Who we are
At OpenUp, our mission is to make mental well-being accessible to everyone. Following a ‘high tech & high touch’ approach, we support companies, their employees, and their families with proactive and practical mental health services. Through our digital platform, clients can access 1:1 check-ins, online courses, articles, videos, group sessions, mindfulness practices, and a team of committed mental well-being experts. As we believe that mental and physical well-being are deeply connected, we have also added Lifestyle Experts to our offering, focusing on nutrition, exercise, and sleep. We offer a truly holistic approach that helps people take ownership of their health. We’re proud to work with forward-thinking organizations and are committed to raising the bar on accessible care.
OpenUp was ranked in the Top 3 on LinkedIn’s Top Startups list for 2023, 2024 & 2025 and is continuously growing. We are expanding our international teams and we are searching for like-minded talent. We are already serving 2000+ companies (e.g. Rituals, Deloitte, Decathlon, KPMG, and McDonalds), through which 600K+ employees have access to our product.
About the role
You own the HR and company experience as a strategic surface. You drive activation from contract to first employee value. You prove ROI so renewals are a formality. You expand revenue by designing the services, playbooks, and value propositions that make HR successful and willing to pay more.
Your scope covers three of OpenUp's growth pillars: boosting signups to OpenUp within companies, driving renewals through measurable HR value and proven ROI, and expanding average revenue per employee (ARPE) through new services and tiered packaging.
Responsibilities
- Activation: Streamline the online journey from contract signed to first employee value delivered. Establish baselines and strategies to drive activation and signups numbers up through structured experimentation, leveraging our tools and capabilities.
Work with customer success to design activation playbooks segmented by company size, industry, and use case. - Customer and revenue expansion: Lead the development and delivery of value-added services that are currently in pilot or discovery phase. This includes Leadership Coaching and Private Sessions. Own the service design: what we offer, how we deliver it, what the menu looks like, and how we improve it based on feedback. Build and evolve the commercial case for expansion, premium offerings, and tiered service packages.
- Discovery, customer intelligence, and commercial strategy: Establish continuous discovery as a core function: customer interviews, usage data analysis, hypothesis formation, and validation cycles. Translate customer signals into packaging strategy and product requirements that feed the build pipeline.
- ROI and outcomes framework: Own and maintain the framework of what HR needs to see to prove value to their leadership, including logic and methodology.
What you'll do
- Collaborate closely with Customer Success who are at the frontline with customers and HR, and drive signups, activation and renewal conversations. You are their strategic partner to design and productise playbooks and you execute them. You collect the intelligence, they surface the signals.
- You collaborate with the PMs and Engineering lead to do your quarterly planning, prioritise and drive outcomes.
- You manage and coordinate the relationship between different stakeholders as needed, including Customers, Customer Success Managers, Experts & Coaches, and Freelancers as needed
- You work with Data (Snowflake, analytics) to define what to measure and interpret results. You don't need to write SQL, but you need to know what questions to ask, what the numbers mean, and what to do about them.
- OpenUp operates an AI-native engineering workflow. You don't need to code or use AI development tools directly, but you need to understand how the team works: specs written in structured markdown, rapid prototyping cycles, and a build-test-adopt-scale model. Your job is to make sure the right things get built by providing clear problem statements, acceptance criteria, and validated customer needs.
Requirements
- Experience in wellbeing, mental health, HR tech, or employee benefits platforms. You have worked in this space, either as a vendor, as an in-house People & Culture / HR leader, or as a consultant. You understand what HR buyers need, how they justify spend, and what makes them champion a platform internally. This is the core qualification.
- 5+ years in a role that combined customer-facing strategy with business outcomes. This could be product management, customer enablement, program management within an HR tech company. We are looking for someone who has owned a business outcome (activation, retention, revenue expansion, ROI), not just delivered programs or shipped features.
- Experience designing and packaging professional services alongside a product: coaching programs, training, workshops, consulting add-ons, or similar. You have built the service, not just delivered it.
- Commercial instinct. You understand pricing levers, packaging strategy, and how service decisions translate into revenue per customer and net retention. You are comfortable working with CS and commercial teams on deal structure and expansion conversations.
- Data-informed decision making. You are comfortable interpreting dashboards, defining KPIs, and working with a data team to answer questions. You don't need to write SQL, but you need to know what good data looks like and what to do when it doesn't exist yet.
Nice to have
- Background in B2B or B2B2C SaaS with land-and-expand dynamics
- Experience building ROI frameworks or outcomes measurement
- Familiarity with AI-assisted workflows or tools like Claude Code, Cursor, or similar
- Experience building for a non-technical enterprise buyer persona (HR, People & Culture, L&D)
- Experience with activation strategy, onboarding optimization, or customer engagement at scale
What the role offers
- A senior IC role with direct strategic impact on company revenue and growth
- Direct reporting to the CPTO, and exposure to board-level strategy.
- A company at an inflection point: you are not maintaining an existing product, you are building the B2B value layer from the ground up
- AI-native engineering environment where PMs ship
- The opportunity to work on something that matters: making mental wellbeing accessible to millions of people across Europe

About the role
As a Senior AI Engineer at OpenUp, you will own the design, build, and evolution of our AI-powered product experiences — starting with our AI Guide, which serves 600K+ users seeking mental and physical wellbeing support.
We're moving from single-prompt to multi-agent architectures that orchestrate tools, manage memory, and hold meaningful conversations at scale. You'll focus on conversational quality, evaluation infrastructure, and user trust — knowing the difference between a demo and a production system.
- Evaluation as a first-class concern. We operate in mental health, where a bad recommendation isn't just a UX issue. You'll build pipelines that measure conversational quality, safety, and clinical appropriateness — with regression detection before every deployment.
- Model-agnostic architecture. You'll design abstraction layers that allow seamless switching between Azure OpenAI, open-source models, and future providers.
- Prompt engineering at scale. You'll design, version, test, and optimise prompts across multiple agent personas — and build tooling that makes iteration fast, measurable, and safe.
You'll collaborate closely with Product, Design, Backend Engineers, and Security to translate product intent into scalable, trustworthy AI systems.
Responsibilities
- Multi-agent architecture and orchestration: Design and build agent-based systems that go beyond rigid scripts. Implement orchestration patterns including tool usage, inter-agent communication, memory management, and context handling. Own architectural decisions about when to use single-agent vs. multi-agent approaches and how agents hand off to each other.
- Evaluation and quality infrastructure: Build and maintain evaluation pipelines that catch regressions before users do. Design golden datasets, automated evaluation rubrics, and monitoring dashboards. Establish quality gates that every prompt change and model update must pass. This is the most critical part of the role in a mental health context.
- Prompt engineering and optimization at scale: Design, version, and optimize prompts across multiple agent personas and conversation types. Build the tooling and processes that make prompt iteration systematic: A/B testing frameworks, performance benchmarks, cost analysis, and safety checks. Treat prompt engineering as a proper engineering discipline with version control, testing, and rollback.
- RAG and grounding systems: Build AI systems grounded in OpenUp content using techniques such as RAG and agentic retrieval. Ensure the AI Guide draws from verified clinical content, articles, and expert knowledge rather than generating unsupported claims. Optimize retrieval quality, relevance, and latency.
- Production AI systems: Productionize AI solutions on Azure, including monitoring, observability, and continuous improvement. Own the operational health of AI features: latency, cost, error rates, and user satisfaction metrics. Work with the platform team on deployment, scaling, and reliability.
- Model-agnostic design for data sovereignty: Contribute to architecture decisions that keep the application layer decoupled from any single model provider. Design configuration-driven model selection and data isolation patterns that enable future private cloud and on-premise deployment scenarios for enterprise customers.
- Cross-functional collaboration: Collaborate with Product and Design to align AI behavior with intended user experience. Work with clinical advisors on safety and appropriateness. Balance user experience with privacy, safety, and compliance requirements (GDPR, EU AI Act).
About you
You are curious about how technology is rapidly evolving and our place in it, and motivated by building solutions that have a real impact on people's lives. You believe that learning comes from action, iteration and feedback, and that strong user value and trust go hand in hand.
- 5+ years software engineering experience, with at least 2+ years building and shipping AI or LLM-based systems in production
- Strong background in data science or machine learning. You understand statistical evaluation, experimental design, and can reason about model performance beyond accuracy scores
- Fluent in Python. Experience with .NET is a plus (our backend stack includes .NET, SQL Server, and ReactJS)
- Hands-on experience with multi-agent or agent-based architectures: orchestration, tool calling, memory, state management
- Experience designing and operating evaluation pipelines for LLMs or conversational systems. You have opinions on how to measure conversational quality and can build the infrastructure to do it
- Experience with prompt engineering at production scale: versioning, A/B testing, regression detection, cost optimization
- Working knowledge of Azure OpenAI or similar LLM platforms (OpenAI, Anthropic, Google)
- Familiarity with embeddings, vector search, RAG, and grounding techniques
- Ability to reason about AI risks: hallucinations, failure modes, adversarial inputs, and trust concerns in sensitive domains
- Bachelor's or Master's degree in computer science, data science, machine learning, or equivalent experience
- Fluent in English
Nice to have
- Experience with open-source LLMs (Llama, Mistral, or similar) and self-hosted model deployment
- Experience working in regulated or trust-sensitive domains (healthcare, mental health, fintech)
- Background in NLP, conversational AI, or dialogue systems
- Experience with Azure AI Agent Service, Semantic Kernel, or similar orchestration frameworks
- Familiarity with fine-tuning techniques and model adaptation
- Knowledge of EU AI Act compliance requirements
