About the role

Our product engineers own end-to-end product experiences for creative workflows—pushing the boundaries of what’s possible in the browser by building sophisticated creative tools that span delightful user interfaces, video & graphics rendering, and the integration of large generative AI models. As a small, collaborative team, our product engineers are trusted with a high degree of ownership and agency—directly influencing what we build and how we build it.

Responsibilities

• Ship end-to-end product experiences for creative workflows, owning features from initial concept through production and iteration
• Push the boundaries of what’s possible in the browser, building highly polished, performant user experiences for complex, media-rich creation and interaction
• Build full-stack solutions that balance performance, scalability, and extensibility—including APIs, data flows, and services that support real-time and asynchronous workflows
• Understand the capabilities and limitations of modern AI systems and work with the team to integrate them thoughtfully into product surfaces
• Instrument, experiment, and iterate rapidly in production, using data, A/B tests, and user feedback to guide decisions

What makes you a great fit

• 2+ years of professional industry experience
• Excellent engineering taste combined with a strong sense of practicality and time-management

• Strong understanding of computer science fundamentals (algorithms and data structures)

Even better if…

• Experience with complex rendering or real-time media processing
• You are grounded, collaborative, and willing to do whatever it takes to help the team win
• You have been a startup founder or an early engineer at one
