Задачи

• Own the product backend, including application APIs, workflows, data models and access controls;
• Own the product side of payment integration by issuing commands, consuming events and keeping product, notification and analytics state consistent with the payments service;
• Shape API and event contracts with payments engineers, including versioning, idempotency, ordering and recovery behaviour;
• Establish engineering standards through code review, automated checks, database tests and safe release practices;
• Make architectural decisions explicit through concise decision records, operational documentation and shared ownership;
• Ship backend changes and test product journeys when integrations fail;
• Own changes spanning the product and a service from contract and data model through release and production behaviour;
• Help other engineers make sound technical decisions through design discussions, review and pairing;
• Make changes across services safer to deliver and easier to diagnose.

Требования

• Ability to explain a concurrency problem and the design change that resolved it;
• Experience designing and evolving APIs and event-driven service integrations, including retries, duplicate events and recovery from partial failure;
• Deep PostgreSQL expertise, including schema design, transactional behaviour, authorisation models, safe migrations and database testing;
• Production experience shipping and maintaining TypeScript;
• Experience taking ownership of an existing production system and making it easier to understand, operate and extend;
• Experience being the engineer others turn to for difficult technical decisions, explaining alternatives, documenting reasoning and helping others implement decisions;
• English is the working language;
• Not primarily seeking infrastructure, cloud operations or deployment tooling work;
• Not seeking a management role with occasional coding;
• Nice to have: Payment or banking integrations, ledgers, identity verification, regulated systems, security or data-residency due diligence, Dutch.
