About the company

Our client is a fast-growing software company.

The role

Raydar is recruiting for this role on behalf of our client. Work across the full stack of a web application, taking features from database to user interface and building automated, AI-driven workflows. You will collaborate daily with the end users who rely on the product, scoping problems and shipping solutions quickly in a small engineering team.

- Build integrations with messaging, email, document signing and billing providers to automate business workflows.

- Improve monitoring, evaluation and infrastructure so automated systems remain dependable at scale.

- Work side by side with in-house domain experts to scope problems, ship fixes and gather feedback the same day.

What we're looking for

- 3 to 7 years of full-stack engineering experience on SaaS applications.

- Experience maintaining and evolving a production codebase beyond the prototype stage.

- Experience building and deploying AI-driven systems to production across interfaces, integrations and backend logic.

- Strong skills in TypeScript and React.

- Experience with backend observability.
