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. Benefits Compensation and benefits - Base salary: USD 200,000 to 275,000 per year - Equity Location and work model - Remote (US or Canada) - Full-time
