Software Engineer, Product

Thinking Machines Lab's mission is to empower humanity through advancing collaborative general intelligence. We're building a future where everyone has access to the knowledge and tools to make AI work for their unique needs and goals.

We are a small team of scientists, engineers, and builders who've created some of the most widely used AI products, like ChatGPT, Character.ai, Mistral, PyTorch, OpenAI Gym, Fairseq, and Segment Anything.

About The Role

As our first Product Engineer, you’ll join a small, mission-driven team building the future of human-AI collaboration. You’ll combine technical prototyping, product intuition, and deep AI integration to create entirely new ways for people to work with AI.

This role is perfect for a builder. You spend your nights and weekends creating things that didn't exist before. You understand that making something exist comes before making it perfect, but you still care deeply about code quality and product taste. You'll work shoulder-to-shoulder with world-class AI researchers and designers, building new interfaces and products from the ground up. You might have built AI products before, but even if you haven't, you're excited to push the boundaries of what's possible with frontier models and infrastructure.

What You’ll Do

• Design and prototype new interaction paradigms, pairing closely with our designer to shape the product through code, intuition, and craft


• Collaborate with world-class AI researchers to translate cutting-edge research into usable, intuitive product experiences that feel natural and powerful


• Move fast with full ownership, working end-to-end from initial concept through prototype to production deployment


• Shape the technical architecture and product decisions that will define how people experience collaborative intelligence


• As you grow in the role, you may have the opportunity to take on expanded responsibilities including technical leadership, product strategy, and mentoring future team members

Required Qualifications

• Technical expertise




• Full stack development experience with fluency across modern web frameworks and cloud infrastructure


• Demonstrated ability to build both frontend and backend systems, with experience hardening prototypes into production-level products


• Strong skills in rapid prototyping and iteration


• Product intuition




• Well-developed product taste and opinions about what great user experience looks like


• Experience with translating technical capabilities into compelling product features


• A bias toward speed and discovery, balanced with care for quality and craft

Strong Candidates May Also Have

• Experience building AI-powered products or working with machine learning APIs


• Background in human-computer interaction


• Previous experience as founder or early engineer at a startup or in a zero-to-one role


• Published projects, open source contributions, or side projects that demonstrate technical creativity

Logistics

• Location: This role is based in San Francisco, California.


• Visa sponsorship: We sponsor visas. While we can't guarantee success for every candidate or role, if you're the right fit, we're committed to working through the visa process together.


• Benefits: Thinking Machines offers generous health, dental, and vision benefits, unlimited PTO, paid parental leave, and relocation support as needed.


• Compensation: Depending on background, skills and experience, the expected annual salary range for this position is $300,000-$350,000 USD.
