About Sana
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.
About the role
You'll build the core agent infrastructure that powers Sana's mission to bring superintelligence to work. This is a greenfield opportunity to define how AI agents plan, reason, and execute across enterprise environments—building systems that reliably handle real-world complexity at scale. You'll work at the intersection of agent architecture, context-, tool- and prompt engineering, and production infrastructure.
In this role, you will
Architect multi-step planning, orchestration, and tool routing for agents
Implement code generation agents and sandboxed code execution
Engineer memory, state, and context packing/grounding strategies
Balance latency, quality, and cost controls for agent execution
Develop safe fallbacks, graceful degradation and robust error handling
Collaborate with platform and search teams to deliver reusable agent infrastructure
Establish safety guarantees and measurable quality improvements
What success looks like
Agent architectures are robust, reliable, and enterprise-ready
Context and tool engineering enables agents to act intelligently, at scale
Clear metrics, automated evaluation, and continuous improvement in agent capabilities
Quality and safety are measurable and continuously improving
Durable building blocks accelerate product teams and unlock new capabilities
Our tech stack
We build on a simple modern stack optimized for both humans and AI:
Backend: TypeScript, Node.js
Frontend: TypeScript, React, Tailwind
Databases: Postgres, Redis
Cloud infra: GCP/Kubernetes/Terraform
