Job description

Engineering|Copenhagen, Denmark (Hybrid)|Full-time

Why we're hiring a Product Engineer

We're building new product domains from zero to market. You'll take ownership of the end-to-end development - from PRD through POC, MVP, to MMP within 6 months. This means shaping requirements, building prototypes for internal review, and shipping MVPs to real users. You'll operate with high autonomy in our innovation lab while collaborating with core domain & platform teams to ensure your work integrates seamlessly and scales.

This isn't a role for spectators - it's for passionate builders who want to master their craft and push the boundaries of what's possible at the intersection of science, data, and AI.

What You'll Do

You will be working across the full stack to ship user-facing features that solve real problems for real users.

• Take ownership of a product domain from PRD through POC, MVP, to MMP within 6 months.
• Build user-facing features across the full stack - React, TypeScript, Node, GraphQL, Postgres.
• Operate as a self-starter while collaborating with core domain & platform engineers for scalability & integration.
• Use AI tools intelligently to accelerate productivity - we expect 4-10x force multiplication through tools like Claude Code.
• Ship early and often using trunk-based development, feature flags, and continuous delivery practices.
• Challenge assumptions, simplify systems, and continuously ask: "Does this make us faster or smarter?"
• Work with Design Systems using atomic composition & component reuse.
• Embrace fast iteration cycles, balancing experimentation with operational excellence.
• Use data and telemetry to drive improvement, not opinion.
• Lead when you're the expert, follow when someone else is, challenging assumptions when necessary.
• Destroy your colleagues at Geoguessr (optional but strongly encouraged).

What You'll Need

Technical Skills

• Full-Stack Development: Strong frontend (React, TypeScript, Tailwind); backend proficiency (Node/TypeScript, GraphQL, API design).
• Database & Data Modeling: Postgres; understanding of graph databases (Neo4j) a plus.
• Cloud Infrastructure: Use what makes sense to move fast; platform team supports AWS migration to scale.
• AI-First Development: Comfortable with context engineering & using tools like Claude Code.
• Modern Practices: Trunk-based development, feature flags, continuous delivery.

Product & Execution Skills

• User-Centric Thinking: Translating needs into features that ship.
• Pragmatic Decision-Making: Balancing speed with quality.
• Shipping Experience: 0→1 or early-stage product experience with real users.
• Design Systems: Experience using atomic composition approach & component reuse.

Executive Skills

• High initiative, low ego: Primarily IC/DRI, secondarily collaborator with PM/engineers.
• Systems thinking with bias for action.
• Strong written communication for async, hybrid collaboration.
• Aptitude and learning velocity over years of experience.

Strong Bonus

• Life Sciences familiarity: DeSci, marketplace experience, or scientific research background.
• Domain interest: Expert networks or knowledge platforms.

Why You Might Hate It Here

• You want predictability & routine.
• You dislike documenting or sharing your thinking openly.
• You see AI as a threat rather than an amplifier.
• You need detailed specifications before starting work.
• You're looking for a "safe" corporate environment - we're not that.

We mean this sincerely: if those points do not work, you'll be happier elsewhere.

Why You'll Love Working Here

• Real Autonomy: You'll own outcomes, not tickets. Your domain, your decisions.
• Ship Fast, Learn Faster: Take a product from zero to market in 6 months. That's the mandate.
• Mission That Matters: Your work directly enables research - accelerating scientific breakthroughs.
• AI-First Culture: We use AI as a creative & operational partner across every function.
• Smart, Small Team: No politics, no bloat - just people who care about mastery and momentum.

Success Metrics (6-month target)

• Product Delivery: Ship a new product domain from PRD to MMP with real users.
• User Impact: Validated product-market fit with measurable user engagement & feedback.

Our Tech Stack

• Frontend: React, Next.js, Tailwind
• Backend: TypeScript, Nest.js, GraphQL
