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, EventBridge, 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
your role at xpate:
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/EventBridge/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.
we’re ready to meet you, if…
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).
