About the roleBrickanta is built by an AI-veteran team. We've been shipping AI systems since 2018 and have built technical products inside some of the world's biggest brands. Now we're pointing that at a $15 trillion industry that software mostly forgot. We build for a domain where reliability matters: high-stakes decisions, messy inputs, real money on the line.We're 20 people and moving fast. At our size you own big parts of the backend that the whole product stands on. You'll get fuzzy problems like "document ingestion needs to be fast and reliable," along with the room to decide what to build and the mandate to ship it.We don't optimize for credentials. We optimize for builders who ship.What you'll build and ownThe core services behind bid analysis, estimation, and procurement: APIs, data pipelines, background jobs, and the plumbing that turns messy construction inputs (documents, specs, standards, drawings) into structured data our AI can reason over and our customers can trustThe data layer itself. Schema design, query performance, and the indexing and batching decisions that keep things fast as records pile upThe architecture that outlives any single feature. You make the calls on data model, service boundaries, when to add a queue, and what breaks at 10x, and the rest of the team builds on them for yearsReliability and evaluation infrastructure: the systems that measure quality, catch regressions, and make AI output repeatable and measurablePerformance and observability that hold up as usage scales, so the product stays fast and debuggable under real loadIntegrations and forward-deployed problem-solving that make it work in the customer's realityThe systems live in production, which means you run them. You're on call for what you build, and you write code that's…
