You are also a central part in how we prove changes to the codebase, so that us as a fast moving AI enabled team can move even faster without slop clean up and reviewing becomes the bottleneck.\nBrickanta is the agentic platform for construction. Agents read tender documents, extract requirements, check them against what a contractor knows about itself, and draft bids, reviews and change orders. Every answer is only as good as the data that is available to the agents.\nThat model is hard to get right. Tenders arrive as bundles of PDFs, drawings and spreadsheets, revised mid-process. The same requirement appears in several documents in different words. Customers are groups with dozens of subsidiaries. Turning that into clean, versioned objects takes real skill and experience.\nWhat you'll own\n1. The ontology\nThe objects everything rests on: organisations and subsidiaries, projects, documents and versions, requirements (krav), company facts, standards, bids and their answers. How they relate, version and carry provenance, so every agent answer traces to a document, page and fact.\nThe pipelines that fill it: parsing, extraction, entity resolution and backfills that turn raw documents into those objects and rerun cleanly when the model changes.\nPermissions and tenant isolation across groups with dozens of subsidiaries.\nHow the codebase is structured around it: schema, migrations that ship daily without breaking what's live, and the typed tools agents use to read and write it.\n2. Shipping at agent speed\nEvals and verification by default: every change to the ontology, a pipeline or a prompt comes with evidence it works.\nRules and playbooks for the repo: how code is structured, tested and shipped, so engineers and coding agents build the same way.\nThe systems that take review off the critical path: automated checks and small, verifiable changes, so reviewers judge decisions instead of reading every diff.\nFirst 90 days\nDay 30\nUnderstand where we stand with the current data model. Improvements to the existing data structures shipped to production.\nDay 60\n3 more concepts modelled and integrated into the product. Map out and experiment with how we can improve our codebase to enable us to run event faster with agents.\nDay 90\nEntire product team is shipping on top of your data model and we as a team are moving faster than ever.\nHow we build\nAgents write most of our code (Cursor, Claude Code, Devin). Writing code is no longer the slow part. Judgement and proof are: the model, the interfaces, and knowing a change works without someone reading every line.\nWe like how Lauren Tan (poteto) at Cursor frames it in pstack: don't let agents just write more code. Go deep and get it right first, leave verifiable evidence, and only then run agents in parallel. Few teams have made that work across many engineers. You'll help us do it.\nMust-haves\nYou have designed and owned the data model of a product customers depend on, and evolved it through migrations and backfills.\nYou have built pipelines that turn messy, unstructured documents into structured data people trust.\nStrong in TypeScript and/or Python, with relational and reactive databases.\nYou have built LLM features in production: tool use, retrieval, structured output, evals.\nYou ship with coding agents daily and know how to verify their work without reading every line.\nYou write clearly. Decisions and interfaces get written down.\nFluent English.\nNice-to-haves\nDocument-heavy domains: legal, construction, procurement, compliance.\nOntology, knowledge-graph or entity-resolution work.\nConvex or Cloudflare Workers.\nYou have built eval harnesses, CI checks or MCP servers other engineers rely on.\nSwedish.\nPractical\nTeam\nProduct & Engineering, reporting to Linus Bein Fahlander (CTO & co-founder), working daily with CJ (Engineering Team Lead)\nLocation\nOn-site by default, Linnégatan 89B, Stockholm\nLevel\nSenior. What you've built matters more than years\nComp\nCompetitive salary and equity\nBrickanta is backed by Northzone and Y Combinator and works with some of the largest contractors in the Nordics.\nProcess\n1.
