Meet the team: Messaging Strategy Frontend (Messaging Product Group)

The Messaging Product Group builds the apps and infrastructure behind marketing Email, SMS and WhatsApp in HubSpot. We work at a serious scale, powering billions of messages per month. We focus on building reliable systems while continuously innovating the product to help our customers achieve better outcomes.

Messaging Strategy Frontend builds the core customer-facing experiences that marketers use every day to create, manage and publish marketing emails and SMS. This is where marketers plan campaigns, iterate on content and make decisions that directly impact their results, across journeys that need to scale and adapt as customers grow with HubSpot.

As a Tech Lead II, you’ll be a player-coach for this space, setting technical direction, shaping product execution and helping a small team deliver high-quality experiences that marketers rely on every day.

• Contribute high-quality React/TypeScript code while guiding architectural decisions, reviewing designs and unblocking others.
• Own technical strategy for the team’s frontend surface area, including modular architecture, design system usage and cross‑app/library boundaries across Messaging.
• Partner in the leadership triad (with Product Management and Product Design) to set goals, sequence work and make trade‑offs that balance customer impact, reliability and iteration speed.
• Drive medium-to-large, multi-quarter initiatives end-to-end, from problem definition and technical proposals through implementation, rollout and measurement.
• Champion reliability and service maturity for our frontend applications. Define SLIs/SLOs, improve performance (bundle size, latency) and keep the app inside our targets.
• Mentor and grow engineers on the team through design reviews, code reviews, pairing and 1:1s, providing clear and actionable feedback.
• Collaborate closely with backend and infra teams across Messaging to design reliable, observable front-to-back solutions that scale across channels.
• Help define and uphold engineering best practices across testing, accessibility, telemetry, experimentation and on-call for our frontend services.
• Play an active role in hiring and onboarding new engineers and in representing HubSpot’s values and HEART culture throughout the interview process.

What you’ll bring

• Deep frontend engineering experience (typically 7+ years) building complex, user‑facing web applications with technologies like React, TypeScript and modern JS tooling, ideally at SaaS scale.
• A proven track record as a technical lead or senior engineer leading at least 2–3 medium‑to‑large projects from design through production, with clear customer or business impact.
• Strong system design and architectural skills in the frontend, with the ability to break down ambiguous product problems, design clear interfaces and boundaries and make pragmatic trade-offs between speed and robustness.
• Experience leading a small team or pod as a player-coach, setting direction, coordinating work and helping others grow while still contributing meaningfully to the codebase.

• A strong sense of ownership over reliability and quality. You’re comfortable digging into performance issues, production incidents and test flakiness and driving them to resolution.
• Excellent cross functional communication skills with the ability to explain technical decisions to engineers and non engineers, write clear documentation and drive alignment across teams and time zones.
• A customer‑ and product‑oriented mindset. You’re motivated by improving marketers’ real workflows (not just shipping features) and you use data and feedback to inform decisions.

Nice to Have

• Experience in marketing technology, messaging, or communications products (email, SMS, WhatsApp, or similar).
• Background working on large-scale, multi‑surface products where multiple UIs share libraries, design systems and infrastructure.
• Experience with performance optimization (bundle size, lazy loading, caching strategies) and service maturity / SLO‑driven development.
• Comfort working in environments with experimentation and AI‑powered workflows, or interest in learning quickly in this space.
• Prior experience in mentoring and developing senior engineers and in collaborating closely with EMs/TLs on promotions, feedback and growth plans.

About the Role

The AI Integrations team builds the tools that bring AI into Telnyx's core products — think voice agents, intelligent messaging, and real-time AI features that improve our customer experience. We need a strong fullstack engineer to help us move faster.

This is a mid-level IC role. You'll own features end-to-end: building React interfaces, writing Node.js services, wiring up databases, and shipping things that work. AI experience isn't required — you'll pick that up here. What matters is that you can build solid fullstack products and want to learn.

What You'll Work On

• Fullstack features across our AI product suite — frontend to database
• Integrating LLMs and AI capabilities into real world applications (with support from the team)
• Building interfaces that make complex AI tools feel simple
• Shipping iteratively — we value working software over perfect plans

Tech Stack

Core (you should know this well):
React 18+, TypeScript, Tailwind CSS, Node.js, PostgreSQL, Prisma, TanStack Query, Docker, Kubernetes

Bonus (nice to have, happy to teach):
Next.js 15+, LLM integration, LangChain/LangGraph RAG/Embeddings, Vector Databases, MCP, WebSockets, WebRTC, Radix UI, Shadcn UI, Framer Motion

What We're Looking For

You're genuinely comfortable across the stack — not a frontend dev who can "do backend" or vice versa. You've built and shipped real features. You take ownership, communicate clearly, and don't need hand-holding.

AI interest is a plus, but we'd rather have a strong fullstack engineer who's curious than an "AI enthusiast" who can't ship.

We move fast on modern web tooling (React/Next, TypeScript, Tailwind). Expect frequent upgrades.

Values

• Ownership — you see things through
• Collaboration — you work well with others and communicate proactively
• Adaptability — comfortable with ambiguity and changing requirements
• Growth mindset — eager to learn, takes feedback well

Our website is our most important marketing asset — where pipeline starts, brand perception forms, and every paid dollar lands. We're looking for a Principal-level engineer who can own the technical strategy for it, end to end.

You'll make architectural decisions, set engineering standards, manage external partners, and shape how the organisation thinks about digital experience as a growth lever. You'll get your hands dirty in code when it's high-stakes or foundational — but your primary value is judgment, strategic ownership, and accountability for outcomes.

The stack: Astro.js, TypeScript, Sanity (headless CMS), HubSpot, GTM, Google Analytics, Zendesk.

What you'll own

• End-to-end technical strategy for the marketing website — platform, architecture, and performance
• Website builds and redesigns from requirements through launch
• Conversion optimisation and experimentation infrastructure — enabling the growth team to move fast
• The website data layer — event architecture and tracking standards that feed broader BI
• Content infrastructure in Sanity — content models, reusable blocks, and COPE pipelines
• AI strategy for the site — evaluating where personalisation, dynamic content, and intelligent search can move the needle
• External partner management and build-vs-buy decisions

What we're looking for

• 12+ years of web development experience, with 5+ years at senior/principal level in B2B SaaS
• Deep expertise with Astro.js and Sanity (or Next.js + demonstrable Sanity depth)
• Proven track record leading major website projects with strategic and organisational implications
• Strong experience with A/B testing architecture, technical SEO, headless CMS, and the analytics/tracking layer
• Ability to communicate technical trade-offs clearly to non-technical stakeholders
• Practical, daily use of AI development tools (Cursor, Copilot, Claude, etc.)

Benefits

• Competitive compensation including equity
• Home office allowance
• Health care and leisure time insurance
• €1,000 annual learning budget
• Sports and wellbeing allowance

#LI-HYBRID

Own the strategic direction of a high-performance B2B SaaS website — and set the standard for how marketing websites drive revenue.

We’re looking for a Principal Digital Experience Engineer to join our Marketing team in Helsinki, Dublin, Amsterdam, or the UK.

Our website is our most important marketing asset — it’s where pipeline starts, where brand perception is formed, and where every campaign and paid media dollar ultimately lands. We don’t need another strong engineer who can build things. We need a recognised authority who can decide what should be built, why, and how — someone who sets the technical strategy for our entire web presence and is accountable for the outcomes.

This is a Principal-level individual contributor role (IC5). You’ll make architectural decisions, define engineering standards, influence senior leadership, manage external partners, and shape how the organisation thinks about digital web experience as a growth lever. You can and will get your hands dirty in the code when it matters — but your primary value is strategic ownership, technical authority, and the judgment to know where your time creates the most leverage.

The stack: Astro.js, TypeScript, Sanity (headless CMS), integrated with HubSpot, Google Tag Manager, Google Analytics, and Zendesk.

The strategic responsibilities you’ll own…

• End-to-end technical strategy for the marketing website — platform, stack, infrastructure, and architecture decisions that you make and are accountable for at the organisational level
• Website builds and redesigns from strategy through launch — you define technical requirements, set engineering standards, oversee delivery, and ensure the final product meets performance, accessibility, and brand standards
• The technical foundation for conversion optimisation and experimentation — designing site architecture where A/B testing, personalisation, and rapid iteration are first-class capabilities. You enable the growth team to move fast; you’re not the person running the tests
• Site performance, Core Web Vitals, uptime, and technical SEO health — developing and documenting performance methodologies that become organisational standards
• The website data layer — defining event architecture and tracking standards that feed the broader BI strategy, working with Data Architects and Analysts
• Content infrastructure strategy in Sanity — designing content models, reusable blocks, and ingestion pipelines that enable a “Create Once, Publish Everywhere” approach across the organisation
• AI strategy for the website — evaluating and championing where AI-driven personalisation, dynamic content, conversational interfaces, and intelligent search can measurably improve the visitor experience or conversion rate
• External partner management — briefing agencies and contractors, reviewing output quality, and making strategic build-vs-buy decisions
• Strategic influence — shaping how senior leadership and external stakeholders think about web as a growth lever, bringing data-backed recommendations, and influencing decisions well beyond your immediate scope

Where you’ll roll up your sleeves…

You’re not above the code — you’re selective about when you’re in it. You’ll get hands-on when the work is high-stakes, architecturally significant, or when you need to set the standard that others will follow. In practice, that looks like:

• Writing and reviewing TypeScript, Astro.js components, and Sanity integrations when the work is foundational or sets a pattern for others
• Managing deployments through GitHub, owning code quality for critical paths, and defining the engineering practices and documentation that keep the site resilient
• Monitoring and optimising Core Web Vitals and mobile performance — diagnosing and resolving issues that require deep technical expertise
• Implementing AI-driven features where you need to evaluate feasibility, set the approach, or prove the concept before handing off
• Building the first version of content models, ingestion pipelines, or integration patterns that engineers across departments will extend

How you’ll raise the bar…

• Mentoring and coaching colleagues at all levels on web best practices, modern development approaches, and AI tooling — acting as a role model across the organisation and potentially the broader industry
• Sharing knowledge proactively through documentation, internal sessions, and external contributions
• Collaborating as a credible technical peer with product and platform engineering teams across departments — not just marketing colleagues

This position is for you if you have…

• 12+ years of professional web development experience, with at least 5 years in B2B SaaS at a senior or principal level
• Deep, hands-on expertise with Astro.js and Sanity; candidates from a Next.js or similar TypeScript-first framework background will be considered provided they can demonstrate Sanity depth and a clear path to ramping up on Astro
• A proven track record of leading major website projects with significant strategic and organisational implications — not just building, but deciding what gets built and being accountable for the outcome
• Experience designing experimentation and personalisation infrastructure — A/B testing frameworks, dynamic content delivery, and the architectural patterns that enable growth teams to move fast at scale
• Strong understanding of technical SEO at a systems level — architecture, rendering strategies, structured data, and crawlability — approached as an engineering discipline that creates compounding gains
• Strong experience with headless CMS architecture — ideally Sanity, but Contentful or equivalent is relevant. Comfortable designing content models, reusable modular blocks, and COPE content pipelines
• Deep experience with the web analytics and tracking layer — event architecture, GTM, and data collection implementation
• Experience integrating with marketing automation and analytics platforms (e.g., HubSpot, Marketo, Segment, Google Analytics/GTM)
• Significant experience working within and actively improving structured engineering workflows — version control, branching strategies, PR review processes, deployment pipelines, and incident management
• Proven ability to collaborate as a credible technical peer with product and platform engineering teams across departments
• Practical, daily use of AI development tools (Cursor, GitHub Copilot, Claude, etc.) and experience implementing AI-driven site features with measurable outcomes
• Demonstrated ability to influence senior leadership and external stakeholders through technical expertise and strategic thinking
• A track record of developing new approaches, methodologies, or standards that have been adopted across an organisation or recognised within the industry
• The ability to communicate technical trade-offs in plain language to non-technical stakeholders and influence decision-making at all levels

To be clear about what this role is and isn’t…

This is a strategic technical leadership role that happens to require deep engineering capability — not an engineering role with some strategy attached. You’ll be assessed on the decisions you make, the standards you set, and the outcomes you drive — not on lines of code shipped.

• You won’t be responsible for product/application development — this is a marketing-focused role
• You won’t be writing content or designing creative — you’ll work with content and design teammates to bring their work to life on the web
• You won’t be doing basic maintenance tickets daily — but if something is broken, you don’t leave it unfixed
• You won’t own data analysis, reporting, or conversion and growth strategy — you’ll be the authoritative technical voice responsible for technical execution and strategic technical leadership

Benefits we offer…

• Competitive compensation package, including equity
• Great work equipment and home office allowance for those in fully remote locations
• Health care benefit and leisure time insurance
• Annual €1,000 personal learning budget
• Sports and wellbeing allowance

Team Overview:

The Amplify Engineering team builds internal tools, platforms, and AI-powered automation that help Klaviyos work more efficiently and at scale as the company grows. We partner across the organisation, including Sales, Marketing, Engineering & Product, Customer Service & Success, and Finance, to solve real operational problems with practical, well-designed software.

Our work spans internal applications, 3rd-party integrations, interactive dashboards, CMS integrations, and robust AI systems and agents that automate repetitive tasks, surface the right information at the right time, and help teams make better decisions. We operate in tight feedback loops with our internal customers, shipping quickly, learning fast, and seeing the impact of our work immediately in how deals move faster, tickets resolve sooner, and launches go more smoothly.

This role is for senior engineers who enjoy turning real-world problems into reliable, scalable solutions. The work is highly visible and has a direct impact on how thousands of Klaviyos get their work done every day.

How You’ll Make an Impact:

The Amplify team builds the internal platforms, automation, and AI-driven systems that power how Klaviyos work every day. As a Senior AI Software Engineer on Amplify, you will:

• Design, build, and own complex internal products and platforms, including internal web applications, APIs, data and event pipelines, and AI-powered workflows used daily by Sales, Marketing, Customer Service & Success, R&D, and Finance teams.
• Lead the end-to-end lifecycle of projects and features – from discovery and technical design through implementation, rollout, and long-term ownership.
• Partner closely with internal customers to understand their workflows and constraints, and translate real operational challenges into scalable, maintainable solutions that measurably improve productivity, quality, and reliability.
• Take ownership of the technical and architectural evolution of parts of the Amplify platform, anticipating scalability, reliability, and observability needs as usage grows.
• Define and maintain operational standards for the systems you own, including SLOs, monitoring, incident response, and follow-up on root-cause analysis.
• Use modern AI tools as part of your day-to-day engineering workflow (e.g. LLM-based tooling for design, coding, testing, and documentation), and help shape best practices for how the team applies AI responsibly and effectively.
• Contribute to shared patterns, tooling, and processes that make it easier for teams across Klaviyo to build high-quality internal tools and AI-powered systems consistently.
• Mentor and support other engineers through design reviews, pairing, and constructive feedback, leaving the codebase and systems better than you found them.
• Collaborate closely with Product, Design, Data, and operational partners to define requirements, trade-offs, and success metrics, ensuring Amplify’s work focuses on the highest-value problems.

Who You Are:

• You care deeply about building software for the long term, balancing technical quality, delivery pace, and business impact.
• You have strong hands-on experience building and operating highly available, full-stack SaaS systems, and are comfortable owning complex problems end to end.
• You’ve led the delivery of significant projects or features independently, including discovery, technical design, implementation, rollout, and ongoing maintenance, and you’re comfortable providing technical direction to others.
• You have deep expertise in one or more areas of modern web engineering (e.g. backend services, data pipelines, internal platforms, or AI-enabled systems) and a solid understanding of scalable, multi-tenant architectures.
• You regularly use AI-powered tools in your development workflow and are curious about applying AI thoughtfully to improve engineering productivity and system capabilities.
• You take ownership of operational excellence for the systems you build, including performance, reliability, observability, and on-call participation where required.
• You enjoy questioning convention and continuously improving how things work, whether that’s architecture, tooling, workflows, or team practices.
• You are a clear communicator and collaborative teammate, comfortable leading technical discussions, writing design docs or RFCs, and keeping stakeholders aligned.
• You enjoy working in small, autonomous, agile teams, shipping incrementally, and partnering closely with product managers and other engineers to deliver better outcomes.

Nice to have:

• Experience building internal tools, platforms, or automations for developers and/or non-technical stakeholders, with a track record of improving reliability, productivity, or operational efficiency.
• Hands-on experience in full-stack environments, including diagnosing and improving application performance, database queries, and complex, multi-service workflows.
• Practical experience building or integrating AI-powered systems and agents; e.g., workflows using LLM APIs/SDKs, agentic or automated workflows, RAG pipelines, or evaluation/monitoring frameworks.
• Experience working with cloud infrastructure (AWS preferred), infrastructure-as-code (Terraform), and containerised environments (Kubernetes), and designing services that run reliably at scale.
