You own the pipelines and interfaces that power the Logistics Brain: heavy batch processing, durable workflows, and the dashboards customers use to chat with their data. If you love distributed systems and Postgres more than prompts, this is your role. (More into RAG and LLM reasoning? See our AI Software Engineer opening.) We're building the Logistics Brain. Every year the logistics industry loses a fortune to invoices, contracts, and claims still handled by hand. Carriers like UPS, FedEx and DHL overcharge and mishandle shipments at scale, and our customers rarely have the tooling to catch it. We turn that mess into a reasoning engine that audits invoices line by line, recovers money, and closes carrier claims automatically — and our customers watch the money come back. $2.5M pre-seed, backed by Seedcamp and Yellow alongside top-tier investors in London, Paris, and Madrid. On-site in Barcelona, moving fast. You'll work in a small, high-agency team where you own problems end to end and see your code hit production the same week. • Own the lifecycle of heavy batch uploads: reliability and observability for long-running jobs that can't afford to drop a single row., • Build durable workflows on Temporal — idempotent, resumable, per-entity. Our UPS claims and ticketing automation run here., • Build the public APIs and dashboards where customers explore and chat with their logistics data, fast enough to feel real-time., • Optimize the data layer for volume without losing responsiveness: indexing, query plans, schema design., • Turn product specs into technical design before writing code, working close to product and the business., • Build the observability and alerting that lets us trust long-running jobs at scale, so failures surface before customers ever feel them., • 2–3 years building scalable backends and responsive UIs., • An AI-first developer who uses agents and plugins to move fast without dropping quality., • Comfortable with heavy data volumes and the batch-vs-real-time trade-offs., • Workflow orchestration engines (Temporal/AWS/similar)., • Postgres optimization and schema design for high load. EXPLAIN (ANALYZE, BUFFERS) is your daily driver., • High-growth startup experience and comfort with ambiguity., • Meaningful equity. We're all owners of the Logistics Brain., • On-site in Barcelona., • AI budget for every tool you want, • Top-spec hardware (MacBook), • Off-sites in Spain and beyond., • Founder/engineering chat - intro, agency, ownership, the Logistics Brain., • Live technical challenge on a real case (1h). Project-style, get something working. You'll use AI tools., • Team fit & final sync - trade-offs and long-term vision. #J-18808-Ljbffr
