Summary

Senior Backend Engineer builds and scales data pipelines and APIs using TypeScript, Python, and AWS for a crypto-focused financial services startup.

We’re looking for a Senior Backend Engineer with deep experience in TypeScript, Python and AWS to help define and build our core data platform. This is a hands‑on role for an engineer who thrives in startup environments — someone who can move fast, make smart architectural decisions, and iterate alongside product and data teams.

What You’ll Do

  • Architect and implement backend services and APIs using TypeScript / Node.js / Python
  • Design and scale data ingestion pipelines for blockchain and crypto datasets.
  • Build reliable, secure systems on AWS (Lambda, ECS/Fargate, DynamoDB, API Gateway, etc.).
  • Collaborate closely with data engineers and product leads to define data schemas, access layers, and platform integrations.
  • Set technical direction and establish best practices for performance, testing, and observability.
  • Contribute to early product decisions, feature prioritization, and roadmap shaping.

What We’re Looking For

  • 5+ years of experience building backend systems in TypeScript / Node.js / Python.
  • Strong foundation in AWS services and cloud architecture.
  • Proven ability to work in fast‑paced startup environments — adaptable, proactive, and comfortable with ambiguity.
  • Experience designing APIs, data pipelines, and event‑driven systems.
  • Knowledge of or strong curiosity about crypto / blockchain technologies.
  • Bonus: exposure to insurance data, risk analytics, or regulatory systems.
