Description
If you take pride in spotless deployments, systems that never go down, and fixes that stay fixed — this role is made for you. We're looking for someone who sees bugs as puzzles, not nuisances. Someone who prefers quality over quick wins. Someone who wants full-stack ownership and actually gets it.
You’ll be the quiet engine behind a clean, stable platform that powers seamless experiences across desktop and mobile. As the team’s first engineer, you won’t be hemmed in by layer-specific roles or bureaucratic dev chains. Instead, you’ll own the codebase from frontend to backend, manage releases, monitor production, and shape the foundation for future growth.
This isn’t a place for constant feature churn or shiny tech experiments. It's a role for a pragmatic problem-solver who builds systems that last — and likes it that way. You’ll work alongside a product-focused leadership team and have the space and trust to do what you do best: make things work, and keep them working. If you want impact without chaos, structure without micromanagement, and autonomy without silos — we should talk.
What you will be doing
- Debug and resolve issues across React, TypeScript, and Python systems using root-cause analysis.
- Maintain and upgrade dependencies, runtimes, and services (e.g., Node.js, Stripe, Firebase) to prevent downtime.
- Manage deployments via GitHub and Vercel, ensuring safe, tested, and consistent production releases.
- Monitor system performance, triage alerts, and implement fixes using tools like Sentry, Mixpanel, Firebase, and Mux.
- Support updates to the Webflow marketing site and analytics tooling for the business and marketing teams.
What you will NOT be doing
- Writing greenfield features week after week — this role is about reliability and maintenance, not product churn.
- Sitting in endless roadmap or sprint planning meetings — your work is driven by impact, not ceremonies.
- Juggling partial ownership over one slice of a stack — here, you own the whole thing.
- Being micromanaged — you'll be trusted to prioritize, execute, and keep the system humming.
Key responsibilities
Ensure platform stability and readiness for future growth by owning maintenance, deployment, and quality across the full stack.

- Comfortable upgrading runtimes and third-party services (e.g., Node.js, Stripe, Firebase)
