Founding Software Engineer, Full Stack

We're building the connective tissue between AI and user data. Today's AI agents are brilliant but mostly blind: they can reason, plan, and execute, but they can't see what's happening across users' work. Every app is a silo. Every database is an island. We're changing that with a focused technical team and great customers, including one of the world's leading AI labs.Airweave turns scattered information into searchable and learned intelligence. We give agents the context they need by ensuring the right information is available when decisions are made.The next wave of software will connect dots across systems and work alongside people naturally. That won't come from a bigger model. It will come from the hard work of connecting intelligence to the data in our work and world. We're building the infrastructure to make that possible.The RoleWe're looking for a full-stack founding engineer to help build Airweave's product layer that connects AI to user data.At Airweave, you'll work across the entire system: from the search pipelines that power AI agents, to the sync infrastructure that keeps data flowing, to the APIs, MCPs, and frontend that developers use every day. You'll ship features that land in production the same day.This is early-stage work. The codebase is young, the architecture is evolving, and your decisions will shape how thousands of AI agents access information.What you'll work onBuild and improve our multi-step, multi-index, distributed LLM search infrastructureDesign and maintain our microservices layer: APIs, MCP servers, and async workers coordinated through Temporal and RedisExtend the sync engine that connects to dozens of sources and keeps data flowing reliablyShip frontend features in React/TypeScript that make complex workflows feel simpleContribute to CI/CD, observability, and the tooling that keeps the team moving fastYou might be a fit ifYou've built and shipped applications end-to-endYou like understanding how systems fit together, not just your sliceYou're comfortable moving between frontend and backend workYou have familiarity with transformers, embeddings, and vector searchYou've worked with async Python, TypeScript, or similarYou're drawn to early-stage environments where things move fast and change oftenNice to haveExperience with data pipelines, infrastructure (Terraform, Kubernetes), or ETL systemsBackground in distributed systems or workflow orchestrationWhat we offerCustomers including one of the world's leading AI labsCompetitive salary (€80K–€100K) with meaningful equity (0.25%–0.75%)Health, dental, and vision coverageWork in-person in San Francisco with a highly-skilled, technical teamDirect impact on architecture and infrastructure decisions from the first weekHiring ProcessFounders call (45 min) – learn about our vision, share your story.Paid work trial (3 days, on-site) – work on a real problem with the team. You'll get a feel for the codebase, how we collaborate, and whether this is the right fit for both sides. We cover your travel expenses.Offer – we decide fast (usually within 24 hours).Our ValuesThe systems we build are made to support real AI infrastructure. They're designed to handle complexity without adding noise, to surface what matters, and to hold up when it counts.We don't wait for specs or permission. High agency means finding what needs to be done and doing it, whether that's a gnarly bug, a missing abstraction, or a conversation no one wants to have. We zoom out to first principles and zoom in to the details, where the real problems live.We have bold opinions, loosely held. We say what we think, change our minds when the evidence points somewhere new, and don't pretend to know things we don't. The best idea wins, not the loudest voice.We bring these values to our product every day.Join UsWe're a small team tackling a big problem.
