Senior Full Stack Developer (Employee)

If you grew up on the Internet like us, you know mental health is more important than ever. But many people face obstacles when seeking traditional mental health care, like finding the right support or having the right insurance.

At Healthy Gamer, we think modern mental health care should be inclusive and affordable. Our coaching service has helped over 13,000 people across 77 countries since it launched in November 2019. Our movement is gaining traction, putting us in the top 0.1% of Twitch streamers and the top 1% of YouTube channels. And we’re working on even more resources to help people find a way forward when they need it.

We’ve made an impact in the gaming community, but that’s not where our mission ends. We want to change how people think about and deal with mental health, and we’re looking for passionate people to help us get there. We are building teams of the best and the brightest in mental wellness, and we are having fun doing it.

Job Type: Employee

The Senior Full Stack Developer is primarily responsible for building intuitive, performant, and accessible user interfaces, with additional ownership of backend logic and API work on our Ruby on Rails stack. You'll work closely with product, design, and engineering to translate ideas and requirements into polished, user-centered experiences, while being comfortable working across the stack when needed.

This role is ideal for someone who cares deeply about usability and quality, enjoys collaborating across disciplines, and thrives in an environment where ownership, mentorship, and continuous improvement are valued.

• Build, maintain, and improve user-facing features using our Svelte SPA, taking ownership from design handoff through deployment.
• Translate product requirements and design mockups into clean, scalable, reusable front-end code.
• Collaborate with product managers, designers, and backend engineers to deliver high-quality features end-to-end; contribute to backend logic and APIs (Ruby on Rails) as needed.
• Ensure consistent implementation of design systems and UI standards across the product.

• Optimize applications for performance, responsiveness, and cross-browser compatibility.
• Write maintainable, well-tested front-end code and participate in code reviews.
• Ensure accessibility best practices (WCAG) are incorporated into front-end development.
• Identify and address technical debt and front-end architecture improvements.

• Help set front-end best practices, tooling decisions, and technical standards.
• Mentor junior and mid-level engineers; provide constructive code review feedback.
• Debug and resolve issues across the front end and, when needed, the Rails backend.
• Stay current with evolving front-end technologies and apply learnings where appropriate.

• 5+ years of professional experience as a front-end or full stack developer.
• Strong proficiency in JavaScript, HTML, and CSS, with experience building SPAs using a modern front-end framework (we use Svelte, but experience with React, Vue, or similar is welcome).
• Comfortable working with REST APIs and some backend experience (Ruby on Rails preferred, but not required).
• Strong attention to detail with a user-first mindset.
• Clear communicator who works well in cross-functional teams and comfortable mentoring others.

• Experience with Ruby on Rails or a similar backend framework.
• Experience with TypeScript.
• Experience implementing browser-side analytics with tools like Google Tag Manager or Amplitude.
• Experience with testing frameworks such as RSpec and Jest.
• Exposure to accessibility standards and inclusive design.
• Experience in healthcare, mental health, or regulated environments.
• Experience in a startup or scaling product team.
