We’re looking for a Senior Full-Stack Engineer with strong back-end expertise to help modernize and maintain critical systems—especially those that aren’t always glamorous (like legacy codebases)—but are essential to the heartbeat of our platform. This is not a management role. We want a dependable, experienced developer excited to improve stability, scalability, and maintainability.

You’ll work closely with our fully remote team to support systems written in Ruby on Rails and PHP/Laravel, with some involvement in React/Next.js/TypeScript front-ends. We’re especially interested in engineers who enjoy getting their hands dirty, take pride in quality, and can work independently with minimal direction.

Why Join Proton

Remote-first culture with flexible hours.
Collaborative, respectful team with a passion for music and code.
Opportunities to grow across technologies and systems.
Competitive compensation and meaningful work supporting independent artists.
Proton is a values driven organization, meaning we aim to align the actions we take with shared ideals. Each team at Proton has its own value system; you can check the engineering team's here.

What You’ll Do

Maintain, refactor, and improve existing systems—including a legacy PHP app with raw SQL.
Contribute to modernizing that app in Laravel, Rails, and GraphQL.
Support our Rails platform with clean, scalable code.
Collaborate with front-end engineers on React/Next.js projects when needed.
Be able to write performant SQL queries for use-cases when the ORM is not performant enough.
Assist in API work, including migrating from REST to GraphQL.
Work across cloud platforms (GCP, Netlify), Docker, and CI/CD pipelines.
Follow Shape Up methodology to deliver focused, high-impact work.

What We’re Looking For

5+ years of back-end or full-stack development experience.
Extensive experience with a modern web application framework (e.g., Ruby on Rails, PHP/Laravel, Django, Spring, .NET, etc.).
Familiarity with Ruby on Rails or PHP/Laravel is a plus — or enthusiasm to quickly learn them if not already experienced.
Strong SQL skills—confident writing queries without an ORM.
Familiarity with React, Next.js, and TypeScript.
Comfortable working in a remote, async-first team with excellent communication skills.
Experience with Git/GitHub, Docker, and cloud infrastructure.
Self-driven, accountable, and eager to learn.

Nice to Haves

Experience with Laravel migrations or legacy-to-modernization projects.
Familiarity with the Shape Up process or similar agile methods.
Awareness of web security fundamentals.
