Note: The job is a remote job and is open to candidates in USA. Imgix is a visual media platform focused on image and video optimization, AI transformation, and fast delivery. The Senior Full Stack Engineer will build and ship end-to-end features across Python backends and React/Next.js front ends, while driving front-end architecture, testing practices, cloud operations, AI-assisted development, mentoring, and third-level support.
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
Skills
- Substantial full-stack professional experience, with demonstrated ability to work across the entire stack independently and lead technical decisions
- Proficient with at least one major cloud platform (the majority of our work is in GCP); able to design, deploy, and operate production workloads in the cloud
- Strong front-end expertise with React, the modern JavaScript/TypeScript ecosystem, and a real sense for UI craft (spacing, hierarchy, responsiveness, accessibility)
- Backend proficiency in Python, or a demonstrated ability to become productive in Python quickly (we welcome strong developers from Node, Go, or Java eager to work in Python)
- Hands-on experience with relational databases (PostgreSQL or similar) and REST/GraphQL API design
- Fluent use of AI coding assistants in real production work—you can speak specifically to how you use them, where they help, and where they don't
- Comfortable working across the stack and driving features to completion without needing a clear handoff at every stage
- Strong written and verbal communication skills, critical to keeping our US and Japan-based teammates aligned asynchronously
- Remote-first: Work from anywhere in the United States, with the option to work from our San Francisco office if you're local
- Experience with Python web frameworks like FastAPI, Django, or Flask
- Familiarity with modern React tooling (Next.js, Tailwind, shadcn/ui, or similar)
- Basic DevOps and CI pipeline literacy
- Experience integrating LLM APIs (Anthropic, OpenAI, etc.) into production applications
- Background in design systems, component libraries, or design-engineering collaboration
- Interest in image/video processing, computer graphics, or web performance
