Agent guide: [/agents.md](https://www.wearedevelopers.com/agents.md). --- # Data Scientist - **Company:** Fixico B.V., - **Location:** Amsterdam, Netherlands - **Experience:** Expert - **Contract:** Permanent contract - **Skills:** PHP (Programming Language), Artificial Intelligence, Laravel, Node.Js, Next.js, Google Cloud, ReactJS, State Machines, Kubernetes, Production Code, Front End Software Development - **Published:** October 10, 2026 - **Apply:** https://fixico.recruitee.com/o/senior-full-stack-engineer-search-allocation/c/new ## About the Role * 8+ years of engineering experience at Staff, Principal or Lead level, and writing production code in the last 3 years * You've built the first version of a matching, allocation, dispatch or assignment engine yourself, not just tuned an existing one * Deep experience with event-driven, long-running workflows: state machines, idempotency, retries, timeouts, at-least-once processing, outbox or saga patterns. Temporal, Cadence or Camunda is a strong plus * You've replaced a live system while it kept running, using shadow mode or gradual cutover, without losing performance * Experience with a two-sided marketplace where suppliers have limited capacity, like delivery, ride-hailing, freight or repair networks. You know how allocation choices affect supplier engagement * You make good decisions with limited data: cold start, calibration, experimentation or bandits. Our markets have hundreds of shops each, not millions of listings * You've been the lead technical voice next to Product and Data, setting direction and making build versus buy calls * Fluent English; Dutch is a plus Nice to have * Tendering, RFQ or auction mechanics * Experience in mobility, automotive or insurance ## Description Every repair job on our platform needs to find the right shop. Our matching already combines smart technology with the expertise of our operations team. Now we want to make it fully automated, measurable and ready for the US. We're looking for the engineer who leads that. You'll set the vision, make the key calls and build the engine that decides which shop gets which job. You start lean, with our Product Manager for dispatch and our Data Scientist. You ship a first version fast, prove it works and grow the team from there. The heart of the job: steer a job to the best shop, invite several shops to quote, or combine both. And do it without double bookings, lost quotes or lower shop acceptance. What you will be doing * Set the technical vision and own the architecture for search, matching and allocation * Ship a first working version fast, then scale it market by market * Build the dispatch flow: steering, tendering and a hybrid cascade with timers, retries and escalation * Build a scoring layer we can tune for speed, price, lead time or quality, without a rebuild * Make the build versus buy calls and decide where AI adds value * Grow the team around the engine, while staying hands-on and building the hard parts yourself Tech stack The engine will be its own service, and you choose how it's built. Language and framework are your call. The condition: your fellow engineers need to be able to maintain and extend it, so you weigh that in every choice. For context, the rest of our platform runs on PHP (Laravel) and Node.js, with React and Next.js on the frontend, on Google Cloud and Kubernetes.
