Senior Product Engineer (Tech Lead)

What You Will Do

• Partner directly with product leadership on architectural decisions, sprint planning and technical execution.
• Ship focused, user-facing applications and developer tooling end-to-end, owning frontend, backend, and workflow design.
• Design and build complex workflows around generative models: chained and parallel generation calls, long-running async operations, streaming results, caching, retries, and graceful degradation around inference that takes seconds to minutes.
• Own the deliverable: you set and hold the quality bar for what ships under your name - correctness, performance, polish, and maintainability - and you review others' work to the same standard.
• Work directly with users and design partners; instrument what you ship, watch it get used, and iterate fast.

Key Qualifications

• 6+ years of software engineering experience (8+ for Staff), with a track record of end-to-end ownership. You've shipped user-facing products, not just components of them, and you've been accountable for their quality in production.
• Deep proficiency in modern web application technologies for the frontend (e.g., TypeScript, React) and backend services, with a strong understanding of web architecture; especially in interactive and real-time applications with performance considerations.
• Fluency with AI-assisted development workflows, grounded in fundamentals strong enough to verify, correct, and own everything you ship — you use the tools to move faster, not to outsource judgment.
• Experience building products on top of asynchronous, long-latency, or streaming APIs.
• A product-minded approach: you form opinions about what users need, validate them cheaply, and change course on evidence.
• Excellent problem-solving abilities and a strong foundation in computer science principles.

Preferred Qualifications

• While not required, experience in one or more of the following is a strong plus:
• Experience in 3D graphics programming and shader development, particularly web frameworks such as WebGL and three.js.
• Experience building applications around generative image, video, or 3D AI models.
• Contributions to open-source graphics or machine learning projects.
• Experience working in VFX, gaming, 3D design, or other industries that focus on high-fidelity visual outputs.
