Senior Full Stack Software Engineer

About the Role

Join an AI engineering software startup building tools for designing and simulating physical systems. You will help take new product capabilities from concept to production, working across the frontend and backend as the team develops an agent-driven approach to building software.

What You'll Do

• Partner with a frontend engineer to improve the product interface and help ship updates to production faster.

• Take on increasingly backend-focused full stack work, including new features, infrastructure, and systems.

• Own features end to end, from architecture through deployment, reliability, and ongoing improvement.

• Establish practical best practices for development with AI coding agents.

• Collaborate with forward-deployed engineers, AI researchers, and product leaders to prototype and refine ideas for industrial customers.

What We're Looking For

• Three to ten years of experience as a software or full stack engineer, including work at a startup or early-stage company.

• Experience taking products or major features from concept through production, with strong ownership and adaptability as priorities change.

• Strong backend skills and capable, mid-level frontend skills, including experience with .NET, React, and TypeScript.

• Comfort using AI coding agents extensively, and the judgment to debug and improve their work.

• Experience owning architecture, deployment, and reliability, plus genuine interest in physical systems, engineering design, CAD, or simulation.

• Based in the United States or Canada and able to work without visa sponsorship.

Compensation & Benefits

Annual salary range: $200,000 to $275,000 USD. Visa sponsorship is not available.

Location

Remote in Canada or the United States, with one week onsite in San Mateo, California, approximately every six weeks.
