About the company

Our client is a fast-growing software company.

The role

Raydar is recruiting for this role on behalf of our client. Join an engineering team as a senior full-stack contributor, shipping production code from the start and owning high-impact projects end to end. Work spans application features, third-party integrations and cloud infrastructure, with an emphasis on dependable systems and fast delivery.

What you'll do

  • Design, build and launch complex multi-step automation features powered by AI.
  • Integrate with external provider APIs for document generation, automated decisioning and fraud prevention.
  • Architect and roll out a new generation of background job processing infrastructure in the cloud, improving visibility into system behavior and stability.
  • Develop full-stack web application features from design through deployment.
  • Keep systems secure and maintainable as usage grows.
  • Contribute product ideas and think through the product implications of what you build.
  • Mentor less senior engineers where the opportunity arises.

What we're looking for

  • Experience at a technology company where software was the core product, ideally a high-growth startup.
  • Strong hands-on TypeScript proficiency, with clear examples of complex systems or products built recently.
  • Experience growing cloud-hosted systems that handle heavy workloads, using AWS and infrastructure-as-code tooling.
  • Working knowledge of React, Node.js and Postgres.
  • A track record of tenure and progression of 2+ years within the same company.
  • Experience in high-growth tech companies, such as venture-scale startups or large technology firms.
  • A keen eye for security risks when handling sensitive data.
  • Ability to work remotely during US time zones.

Bonus points

  • Familiarity with modern AI product development practices such as evaluations, experiment design and dataset curation.
  • An operations-minded approach to building infrastructure that is stable, easy to monitor and simple to maintain.
  • Experience designing and scaling complex relational database schemas.
  • Fintech experience.
  • Active GitHub profile or side projects.
