Senior Full Stack Software Engineer

About this role

## About the Role

We’re hiring a Senior Full Stack Engineer who genuinely enjoys the front-end and wants to actively push our technology forward. Reporting directly to a hands-on Senior Engineering Manager, you’ll work across our entire stack—our backend runs on Python, our front-end on Next.js. You’ll spend a meaningful portion of your time crafting the surfaces our customers actually touch: the dashboard, the image-editing UI, and the APIs for managing accounts and configuration.

As we continue modernizing our stack, we’re looking for an engineer who looks for meaningful improvements, not just maintenance—someone who raises the technical bar through hands-on work, thoughtful code review, and clear documentation, and treats CSS and UI craft as real engineering, not a chore.

This is a hands-on senior role. In a given week you might design a React component library, optimize a slow Python endpoint, debug a CI pipeline, or review an AI-generated pull request. If that variety is the kind of work you find most engaging, this role is designed for you.

## What you’ll do

• 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 runbook...
