Position Summary

The Senior Software Engineer, Full-Stack will own meaningful pieces of Epic's web application end-to-end—from Angular UI through PHP and Go services to MySQL—and help raise the quality bar for the engineers around you. You are an experienced engineer who works independently on complex problems, makes sound technical decisions, and pulls in the right people when a decision touches another team. You will design and ship features that span the stack, partner with product, design, data, and infrastructure to land them well, and mentor more junior engineers through code review and pair work. Our back-end is multi-language: PHP/Symfony powers our long-standing application code, and we are actively investing in Go for newer services—senior engineers help drive that evolution thoughtfully rather than reflexively rewriting what works.

This is a fully remote, US-based role working closely with a global engineering team with members in the US and China.

Key Responsibilities

• Design and ship features end-to-end across the stack—Angular front-end through PHP/Symfony and Go back-end services, against MySQL—taking ownership from spec to production
• Make sound technical decisions on architecture, data modeling, API design, and state management; document trade-offs and align stakeholders before significant choices land in code
• Operate independently on ambiguous problems, breaking down scope, surfacing risks early, and shipping in safe increments
• Partner cross-functionally with product, design, data engineering, infrastructure, and content on features that span team boundaries
• Drive code quality through thorough code reviews, raising standards on testing, readability, and maintainability across both front-end (Angular, RxJS, NgRx) and back-end (PHP/Symfony, Go) codebases
• Mentor junior and mid-level engineers—pair on hard problems, give actionable code-review feedback, and help them grow into larger pieces of work
• Improve the developer experience of the codebases you touch—tooling, tests, build times, and observability
• Leverage AI-assisted development tools to accelerate delivery, applying the same review and quality bar to generated code as to anything else, and exercising judgment about where they help and where they don't
