The Role

Backflip is looking for a Senior Software Engineer to join our team as a highly skilled individual contributor. In this role, you’ll work across the stack to build new user-facing features and develop integrations with CAD and other third-party applications. You’ll collaborate closely with product managers, AI researchers, and other engineers to bring new ideas to life and scale them into production-ready systems.

This is a hybrid role based in our San Francisco headquarters.

What You’ll Do

• Build and maintain full-stack web applications using modern frameworks and tools
• Develop integrations with CAD software, 3D tools, and other third-party applications
• Create and maintain connections with external web services and APIs
• Collaborate with product managers, designers, and AI researchers to design and deliver user-facing features
• Contribute to technical architecture, design reviews, and engineering best practices
• Own projects from prototype through production, ensuring reliability, performance, and excellent user experience

What We’re Looking For

• 5+ years of professional software engineering experience
• Strong experience in full-stack development, ideally with JavaScript/TypeScript and Python
• Familiarity with frameworks like React and Express, and technologies like Redis, Postgres, and Docker (or equivalent experience with similar systems)
• Experience building plugins for desktop applications
• Strong product sensibility and ability to work closely with cross-functional teams
• Excellent problem-solving skills with a balance of pragmatism and attention to detail
• Expertise in 3D graphics for the web, including frameworks like three.js or react-three-fiber, WebGL, and a strong understanding of rendering pipelines, geometry, and graphics performance optimization

Nice to Have

• Experience with CAD, 3D graphics, or geometry-related software development
• Background in another engineering discipline (mechanical, electrical, civil, etc.) or experience bridging hardware and software
• UI/UX sensibilities or experience working closely with design teams
• Exposure to building products around core AI technologies

Compensation

The expected base salary range for this role is $175,000 – $240,000, plus equity. Final offers will be based on experience, interview performance, and alignment with role requirements.
