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.
You’ll be responsible for designing APIs, building scalable microservices, and connecting blockchain data sources to enterprise-grade insurance analytics.
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.
