At Bloomerang, we believe change happens on purpose. We champion the power and potential of nonprofits, igniting next-level impact with the team and technology built for purpose. Our powerful giving platform and stellar support enable tens of thousands of nonprofits to raise more, recruit more, and retain more, fueling maximum impact and raising the bar on what’s possible for the nonprofit sector.

The Role

As a Senior Full-Stack Software Engineer on the Events & Auctions team, you'll help build the tools nonprofits use to run galas, auctions, and live fundraising events. You'll take a problem from "what do our customers need?" all the way to working software in production: the React interface, the PHP behind it, and the data underneath. The work leans heavier toward the frontend than the backend, and you'll work alongside Product, QA, and fellow engineers to deliver a complete solution rather than handing work across a stack boundary.

The problems we work on are rarely fully specified. We're looking for someone who can make progress with 70% of the picture, state their assumptions, and keep moving; who sees work through to done, including the tests, the rollout, and the follow-up; and who makes the people around them better. AI tools are part of how our team builds software every day, and we expect you to use them well and keep learning as they change.

What You Will Do

• Own solutions end to end. Shape the approach, build the UI, write the PHP services and APIs, design the data changes, test it, and ship it safely behind feature flags.
• Solve real problems. Find the actual problem behind the request, work through ambiguity, and drive it to a genuine resolution rather than a plausible-looking one.
• Work with AI as a normal part of the job. Use tools like Claude Code day to day for coding, debugging, research, and review, and apply the judgment to tell a real fix from a convincing one.
• Build quality in. Write unit, component, Storybook, Playwright, and PHPUnit tests, and give and receive thoughtful code review.
• Diagnose production issues. Use logs, Sentry, and system-level knowledge to find root causes and keep them from coming back.
• Collaborate across disciplines. Partner with Product, QA, and the mobile engineers who build our iOS and Android terminals, and communicate tradeoffs clearly.

What You Need to Succeed

• Deep, recent experience with React and Type Script in production, including state management (Redux Toolkit or similar).
• Strong, recent professional experience with PHP (8.x preferred). PHP is required.
• AI proficiency. Hands-on, day-to-day experience building with AI coding tools such as Claude Code or Git Hub Copilot, including prompting and giving context effectively, and critically verifying AI-generated code with tests and review before it ships.
• Strong modern web fundamentals: accessible, responsive UI, Tailwind or utility-first CSS, and reusable component design.
• Strong SQL and relational database skills (MySQL), including query design and performance.
• Solid understanding of REST API design, async/queue-based processing, caching (Redis), and production debugging and observability.
• Experience with automated testing across the stack (Vitest/Jest, React Testing Library, Storybook, Playwright,…
