Senior Backend Developer - xpate

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).

what working at xpate looks like:

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.
