Senior Software Engineer - ServiceCore

About the Role

ServiceCore builds the software that runs the portable sanitation and liquid waste industry — a niche most people have never thought about but that keeps job sites, events, and communities operational. Our customers rely on us daily, and the Senior Software Engineer owns the technical quality of what we ship: designing systems, guiding architectural decisions, and driving down the technical debt that would otherwise slow us down.

You’ll work as the technical anchor of a small, cross-functional pod of 2–3 engineers, partnering closely with Product and Design. You’ll mentor SE1s and SE2s, participate in customer discovery to keep your work grounded in real problems, and hold the line on quality through thoughtful code review and a strong testing strategy.

Our stack is Angular & Typescript (frontend), PHP/Laminas Framework (API), MySQL, AWS, and Ionic ( for mobile. We work fully remote, come together once a year as a company, and do quarterly planning as a team. If you’re near Denver, CO, a hybrid option is available.

What You'll Do

• Architect features and systems end-to-end — from data model through API through UI — and own the implementation quality across your pod.
• Define and champion the testing strategy for your team: what to test, how to test it, and how to keep the suite maintainable over time.
• Identify and address technical debt proactively — propose the tradeoffs clearly, get alignment, and execute.
• Mentor SE1s and SE2s through code review, pairing, and direct feedback; raise the technical bar of your team without being a bottleneck.
• Participate in customer discovery with Product to ensure your technical decisions are solving real problems, not imagined ones.
• Lead AI-assisted development practices on your team — using tools like Cursor, Copilot, and agentic workflows to increase throughput and help your teammates do the same.

What We're Looking For

• 5+ years of professional software engineering experience, with clear ownership of complex, production systems.
• Strong command of backend development (PHP, Java, or similar object-oriented language) and relational databases (MySQL/MariaDB preferred).
• Solid frontend experience with a modern framework — Angular preferred, React or Vue considered.
• Hands-on experience with AI-assisted development tools (Cursor, GitHub Copilot, or similar) as a real part of your workflow, not an experiment.
• Demonstrable ability to architect systems: you’ve made hard technical decisions, documented them, and stood behind them when questioned.
• Track record of mentoring more junior engineers and improving the team around you, not just your own output.
• Comfort operating in a product-led environment — you engage with the ‘why’ behind features, not just the spec.
