Senior Software Engineer, Design Services

What you'll own

• A meaningful area end to end: a slice of the customer design experience, designer tooling, the iOS app, or a backend service.
• AI-backed features: you'll define how they behave, evaluate output quality, and iterate based on real customer impact.
• Work across the 3D and Studio stack, the TypeScript graph, the PHP monolith, and the agent platform as the work requires.

What success looks like

• In 90 days: you've ramped on the stack and shipped real improvements in your area.
• In a year: you own an area of the platform, you've raised its quality and reliability, and you're the person the team goes to for it.

How we work with AI

AI is a core part of how we build, and we're investing heavily in it, well beyond using it to write code faster.

• The team works with Claude Code, Codex, and Cursor and builds on our agent platform and LLM tooling.
• We're building an internal harness so agents can handle real engineering work, like error resolution, bug fixes, and feature enhancements, around the clock.
• You'll use AI intentionally, help push this forward, review output critically, and stay accountable for everything you ship.

Must-haves

• Strong full-stack fundamentals. You understand how web, mobile, APIs, services, and databases fit together.
• You use AI tools as a real part of your engineering workflow and own the output.
• You've owned meaningful parts of a product or system in production.
• You ramp quickly and are comfortable with ambiguity and unfamiliar code.
