Job description
We’re hiring a hands-on Backend Developer to build and ship production serverless services for a fintech platform. Tech stack Languages: TypeScript, Node.js (18–22) AWS: Lambda, DynamoDB, S3, SQS, Event. Bridge, Step Functions Databases: DynamoDB, PostgreSQL Frameworks / middleware: Serverless Framework, Middy Libraries: Zod (schemas/validation), Winston (logging), AWS X-Ray (tracing), Luxon (dates) Testing: Mocha, Sinon Tooling: ESLint, Prettier, Terraform, GitHub Actions Build and evolve Lambda-first microservices that handle real money flows and integrations.
Design REST APIs with type-safe schemas (Zod) and contracts that don’t rot. Model data in DynamoDB (access patterns first) and use PostgreSQL when relational fits better. Ship event-driven workflows with SQS/Event. Bridge/Step Functions: retries, idempotency, dead-letters, backpressure. Ensure observability: structured logging (Winston), distributed tracing (AWS X-Ray), actionable metrics.
Write tests that protect releases (Mocha/Sinon), keep quality bars high, and reduce regressions. You have strong hands-on backend engineering experience in TypeScript / Node.js. You have real AWS production experience — not “used Lambda once”, but built, operated, debugged, and fixed systems in production. You have the ability to ship fast without trashing quality: clean code, predictable delivery, and solid engineering fundamentals.
You use AI tools daily to accelerate output (coding, debugging, analysis) and improve outcomes. You have English at B2+ level (the team is English-speaking). A competitive salary (depending on what you bring). Everything you need to succeed, with flexibility built in — from flexible hours and hybrid/remote work options to private health insurance and paid time off.
Top-of-the-line Apple gear to fuel your work. A workspace designed for focus and collaboration. Ownership of your work end-to-end, with the freedom to move fast and make a real impact. Celebrated wins, opportunities to grow and a culture where voices are heard and chances to grow are ever-present.

If you want real impact, freedom to innovate, and work that drives change - xpate is the place for you.
