Senior Full Stack Software Engineer

Imgix is the complete visual media platform for teams that care about performance. We’re hiring a Senior Full Stack Engineer who will work across the entire stack, focusing on both front-end and back-end development, while driving technical improvements and mentoring teammates.

Responsibilities:

• Design, build, and ship: Own full-stack features end-to-end, from API design through to polished, accessible UI
• Drive front-end architecture: Lead decisions on component patterns, state management, performance, and design system evolution
• Champion our testing culture: We have a strong testing culture company-wide—we want someone to bring that same rigor to our front-end and account-management code. You’ll set the bar here: choosing the tooling, establishing the patterns, and turning solid coverage into a team habit
• Write clean backend code: Maintain and build scalable Python APIs, collaborating on data modeling and GCP infrastructure
• Build with AI tools: Use Claude Code, Codex, Gemini, or similar daily—for prompting, reviewing, and refining code
• Act as an L3 escalation: Join a genuinely low-volume, third-level on-call rotation. Our SREs resolve Tier 1 and 2 issues with runbooks and rollbacks, so escalations are rare—the manager you’d report to has been in this rotation since late 2024 without a single page
• Mentor and elevate: Guide teammates informally through code review, pairing, and excellent documentation
