Fullstack Product Engineer (Agents)

At Sana, we're on a mission to bring superintelligence to work—a seamless, beautiful way to access all your company’s apps, knowledge, and data. We are obsessed with making AI agents do real work to empower our users to process and act on knowledge at an unprecedented scale.

We’re a talent-dense team of engineers and designers in Stockholm, united by a passion for building great products with deep technical excellence. Our backgrounds span AI research at Google, distributed systems at Spotify, product design and AI infrastructure at Apple, competitive programming, and scaling fast-growing startups. At Sana, everyone is an owner. We cut out processes, maximize impact, and value rapid prototyping and iteration.

Our AI tools already help over a million people learn and work better across hundreds of leading enterprises. But we’re just getting started—there’s so much more to build. Join us to tackle some of the most challenging and meaningful problems of our generation.

Ship customer-facing value quickly in small teams—owning everything from problem definition through UX, API, and instrumentation. You’ll work end-to-end to deliver features that delight users and move the needle for Sana and our customers.

• Own features from design to deploy—frontend (React/TypeScript), backend (Node/TypeScript) and database (Postgres)

• Integrate with agent and retrieval APIs to deliver seamless product experiences

• Instrument products, run A/B tests, and iterate quickly with design and PM

• Make pragmatic trade-offs and thrive in ambiguous 0→1 product spaces

• Collaborate closely with stakeholders, users and teammates to define and solve the right problems

• Features ship fast, delight users, and drive measurable impact

• End-to-end ownership is the norm—problems are solved, not handed off

• Product instrumentation and A/B tests inform every iteration

• You are a force multiplier for your squad, making everyone around you better

• Ambiguity is an opportunity, not a blocker
