Software Developer Engineer

We are looking for a Software Developer with 3-4+ years of experience to join a 3-person team building AI-powered CAD software that is creating a foundation model for mechanical engineering. You'll be a curious, ownership-driven engineer who can pull their own weight and ship production code end-to-end. This is a ground-floor opportunity at a YC-backed startup that has answered its fundamental technical questions and is now pouring gasoline on the fire, the team is doubling in the next few months . The founders were early employees (first 10) at Cruise Automation (acquired by GM for $1B+) and are recreating that kind of magic.

Responsibilities:

• Own the design, architecture, and delivery of core systems end-to-end: from ambiguous problems to shipped, maintained products.
• Partner with founders to turn fuzzy goals into technical roadmaps, and drive them to ship.
• Set and raise the engineering bar: code review, testing standards, and architectural direction across the codebase.
• Lead the design and productionization of the machine learning systems behind our AI-powered CAD.
• Troubleshoot, debug, and resolve defects: from everyday bugs to systemic issues in performance, reliability, and scalability.
• Build on and improve our engineering practices (CI/CD, testing, observability) as the team and product grow.
• Help shape our engineering culture and team as we grow

Requirements:

• 3-4+ years building and shipping production software.
• Deep proficiency in Python and experience designing backend services that scale (e.g., Django, Flask, SQL).
• Hands-on experience building and deploying machine learning models in production.
• Track record of owning systems end-to-end and making sound architectural tradeoffs with limited direction.
• Comfort with ambiguity and a track record of raising the technical bar of the teams you work with.
• Strong communication and teamwork skills.
• Strong Computer Science fundamentals

Bonus Skills:

• CAD, geometry, or computational-geometry domain experience.
• C#/.NET (some add-ins are C#).
• Experience packaging and shipping native desktop applications on Windows and macOS, including code signing.
• Deep AWS / cloud / infrastructure / DevOps experience at scale.
• Early-stage startup or 0→1 product experience.

What We Offer:

• Competitive salary and equity options.
• Comprehensive health insurance, including medical, dental, and vision coverage.
• Catered lunch.
• Unlimited time-off.
• A collaborative and inclusive work environment.
• Opportunities for professional growth and development.
• The chance to be part of a passionate team building innovative products.
