Senior Full Stack Software Engineer

ABOUT THE ROLE

Join an early-stage AI company developing software for engineering design and simulation of physical systems. You will help build a new product, accelerate frontend delivery, and take on broader backend-focused full stack work as the product and team evolve.

WHAT YOU'LL DO

• Collaborate with the frontend engineer to improve the product interface and move features into production faster.
• Build new product capabilities, infrastructure, and systems, with a growing focus on backend work.
• Own features end to end, including architecture, deployment, and reliability.
• Establish effective practices for AI-assisted, agent-driven software development across the team.
• Partner with field engineering, AI research, and company leadership to prototype and improve product ideas for industrial use cases.

WHAT WE'RE LOOKING FOR

• Three to ten years of experience as a full stack engineer or software engineer, including startup experience.
• Experience taking products or substantial features from concept through production, with strong ownership in changing environments.
• Full stack web engineering experience, with strong backend skills and the ability to build and debug frontend features.
• Experience with .NET, React, TypeScript, and AI coding agents, or closely related tools and technologies.
• Interest in physical systems, engineering design, CAD, or simulation; experience limited to computer vision, robotics, or self-driving systems is not a fit.
• Authorized to work in the United States or Canada without visa sponsorship.

COMPENSATION & BENEFITS

Base salary is $200,000 to $275,000 USD annually. Visa sponsorship is not available.

LOCATION

Remote, with the primary location in Canada. Candidates must be based in the United States or Canada and able to spend one week onsite in San Mateo, California, every six weeks.
