Senior Backend Developer - Remote

Overview

We’re hiring a hands-on Backend Developer to build and ship production serverless services for a fintech platform. This role is about clean execution: designing APIs, owning integrations, and delivering reliable AWS Lambda microservices with strong observability and test discipline. AI tools are part of the daily workflow.

In Short

• 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.

Requirements

• 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).

Benefits

• 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.
