What's the opportunity?

Fin is the #1 AI agent for customer service. It resolves over 1M customer conversations every week, and we're just getting started. We're on the cutting edge of defining how AI agents should work — inventing paradigms that didn't exist six months ago and discovering entirely new problem spaces every time we push the technology further.

This role sits at the heart of the Service Agent pillar — 12 teams and growing, building every capability that makes Fin work. You'll partner at the strategic pillar level: broad context across work streams, deep technical understanding of how Fin operates end-to-end, and the autonomy to decide where you need to go next. When we need a new work stream spun up from scratch — a brand new team, an ambiguous problem space, aggressive timelines — you're the person who makes that happen.

The competitive landscape is intense. Fast-moving AI-native startups are coming hard for this space, shipping aggressively and going after the same deals we are. We need someone who thrives under that pressure, who can maintain technical excellence while moving at startup speed within a company that has the resources and customer base to make that speed count.

What will you do?

• Partner at the strategic pillar level. You'll have broad context across work streams and use that to inform technical strategy and investment priorities. What should we care about? Where should we invest? Where do you need to step in? These are your decisions.
• Spin up 0-to-1 work streams. Bring together engineers who've never worked as a team, disambiguate the problem space, build momentum under aggressive timelines, set high expectations, and drive execution.
• Execute on the most ambiguous, highest-stakes problems. You're hands-on. You write code, you ship features, you're deep in the weeds. We've seen too many Principal Engineers who are brilliant but too far from execution to be effective here.
• Lead experimental work at the AI frontier. Run your own A/B tests, do prompt engineering, build evals, and calibrate accuracy, cost, and latency for LLM-powered features. Much of what we're building are new paradigms for customer-facing software.
• Shape long-term technical strategy through execution. Your hands-on work informs the architecture. You're simultaneously building and thinking about what needs to change about how we build products — data models, system design, the shift from GUI-first to agent-first interfaces.
• Work across the full stack in an AI-first development environment. Every engineer has Claude Code with unlimited tokens and a sophisticated ecosystem of MCP servers, skills, and shared context. You'll push the boundaries of what's possible with AI-assisted development and help shape how the entire engineering org works.
• Raise the bar for the people around you. Give direct, actionable feedback that changes outcomes. We don't need someone who mentors juniors on the basics — we need someone who can accelerate and grow the senior and staff engineers around them.

What are we looking for?

The core requirement: engineering depth and product thinking. We need someone who combines deep engineering ability with strong product and design instincts — not one or the other. We don't want engineers who are technically brilliant but disconnected from the product. And we don't want product-minded engineers who have great instincts but can't execute at the level this work demands. You need to be able to both build complex systems AND identify the right problems to solve. This is the single most important dimension we evaluate on.

Beyond that:

• Operated at real scale and has builder energy. You've likely spent time at companies operating at significant scale — the kind of environment where you've seen what large-scale distributed systems actually look like in production. But you also have startup DNA: urgency, resourcefulness, a bias toward building over discussing.
• AI fluency. You're actively experimenting with AI-assisted development, pushing the boundaries of what's possible, and forming opinions about how it changes the way teams build software. This matters more than any specific stack experience.
• Deep technical depth with breadth. You can go deep into the weeds on at least one technical domain, but you also navigate complex multi-team systems with ease. In conversation, you move fluidly from business context to technical strategy to implementation details.
• Communication as a superpower. You can explain to leadership why a technical investment matters, align multiple teams around a complex project, and then walk an engineer through the gnarly implementation details. This role lives and dies on your ability to communicate across every level.
• Extreme autonomy. You partner with the Engineering Director on where you think the pillar needs to go next. You identify problems, form convictions, and act on them. If you're the kind of engineer who waits to be told what to work on, this isn't the right role.
• Critical thinking about the business. You understand what Intercom is optimizing for and translate that into technical decisions. Which work streams need investment? Where are we falling behind? What should we defund to go harder somewhere else? You think at this level naturally.
• At least ~10+ years of experience, with significant time as a technical leader driving complex projects across multiple teams and stakeholders.
• Stack agnostic. We use Ruby on Rails, React (migrating from Ember), and AWS. But AI tools increasingly abstract the stack — what matters is your ability to learn, build, and operate effectively with tools like Claude Code. If you're great with a high-level programming language and fluent with AI-assisted development, you'll be productive fast.

Why Intercom, why now?

Fin is #1 — and the race is heating up. We built the leading AI agent for customer service, but fast-moving AI-native startups are coming for this space. This is one of the most consequential competitive moments in tech history, and the engineering decisions made in the next 12 months will determine who wins.

A rare pivot that actually worked. Intercom has been building for 15 years — deep product, massive customer base, strong revenue. But unlike most legacy SaaS companies, we made a successful pivot to AI. While most of SaaS trends down, Intercom trends up. We recently raised $250M to go even further even faster..

AI-first engineering culture. Every engineer gets Claude Code with unlimited Opus 4.6 tokens and 1M context. We're investing heavily in the platform capabilities — MCP servers, skills, shared tooling — that make AI-assisted development genuinely transformative. You'll be at the sharp edge of figuring out what this means for how teams work.

The sweet spot. Big enough to have real resources, customers, and revenue. Small enough that you have genuine agency. Bold enough to make decisions that most companies of this size wouldn't. You come to Intercom if you want the impact of a startup with the backing of a company that's been winning for 15 years.

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

#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

Toast creates technology to help restaurants and local businesses succeed in a digital world, helping business owners operate, increase sales, engage customers, and keep employees happy.

Now, more than ever, the Toast team is committed to our customers. We’re taking steps to help restaurants navigate these unprecedented times with technology, resources, and community. Our focus is on building the restaurant platform that helps restaurants adapt, take control, and get back to what they do best: building the businesses they love. And because our technology is purpose-built for restaurants, by restaurant people, restaurants can trust that we’ll deliver on their needs for today while investing in experiences that will power their restaurant of the future.

As a Principal Infrastructure Engineer at Toast, you will lead the architecture of systems powering our developer ecosystem and software delivery lifecycle. This includes platforms for code collaboration, service discovery, developer workflows, and CI/CD at scale.

Toast has invested in a strong foundation of developer tooling and platforms. This role is an opportunity to build on that foundation by connecting these systems into a unified intuitive experience, helping engineers move from ideation to production with speed, clarity, and confidence.

AI-assisted development is deeply embedded in engineering at Toast. The majority of engineers use AI tools daily, and AI agents participate in code review, build triage, and operational workflows. This is your chance to pioneer how the internal developer platform evolves, creating a future that empowers both humans and agents to achieve more.
