Senior Full Stack Software Engineer

About the company

Our client is a software company.

The role

Raydar is recruiting for this role on behalf of our client. Join a small engineering group as a hands-on full stack developer, first helping speed up user interface delivery and then shifting toward backend-heavy work. You will take responsibility for features across their whole lifecycle and help colleagues adopt AI-assisted ways of writing code.

What you'll do

- Partner with a frontend engineer to remove delivery bottlenecks and get interface improvements into production faster.

- Gradually take on more backend-oriented work, including new capabilities, infrastructure and core services.

- Drive features from initial design through release and ongoing stability, with little supervision.

- Introduce and promote effective practices for developing software with AI coding agents.

- Work alongside customer-facing engineers, researchers and founders to prototype and refine new product ideas.

Requirements

What we're looking for

- Roughly 5 years of professional software engineering experience (a range of 3 to 10 is considered), including senior full stack or comparable roles.

- A history of launching new products or substantial features from an early idea into live use, ideally in a fast-paced startup.

- Strong backend-leaning full stack skills with at least intermediate frontend ability, and the judgment to debug AI-generated code that falls short.

- Hands-on responsibility for system design, releases and operational stability.

- An assertive, opinionated approach to AI-assisted development and getting the most out of coding agents.

- A self-directed builder mindset: high ownership, little need for guidance, and flexibility when priorities change.

- Genuine interest in the company's mission and a thoughtful reason for wanting to join.

- Residence in the US or Canada and openness to periodic on-site visits to a California office, roughly one week in every six.

- Existing authorization to work in the US or Canada without sponsorship.

Bonus points

- Interest in physical systems, CAD or simulation.

- Based in the San Francisco Bay Area.
