The Role

 How You'll Show Up

• Own your work and drive it to done. Treat commitments as promises, push through the murky middle, and share bad news early.
• Communicate directly. Ask the question, raise the concern, and keep the team in the loop.
• Use good judgment and welcome feedback. Make sound decisions with incomplete information, and treat feedback as useful information to act on.
• Keep learning. Pick up new tools quickly and let go of approaches that no longer fit.
• Think like a product engineer. Connect technical work to business goals and to the experience of nonprofits and their donors.

What You Will Do

• Design, build, test, and ship features and integrations across the payments stack, from processor APIs and webhooks to the UI. Partner with product, design, and support to understand the problem nonprofits and their donors face before you build.
• Use agentic AI tools every day to deliver value faster, and help shape the harnesses, guardrails, and conventions that keep AI-generated code aligned with our architecture.
• Keep payment flows secure, reliable, and observable. Debug production issues to the root cause, and improve the live codebase, including legacy code, step by step with the team's agreement instead of through unilateral rewrites.
• Make the team better. Review code, pair with teammates, and share what you know so it doesn't stay siloed. Represent payments in cross-team work and bring that context back.

What You Need to Succeed

AI Fluency

• Hands-on experience taking AI-assisted or AI-driven work to production, beyond writing prompts, in large, established codebases, not just greenfield projects.
• Enough architectural understanding to codify it into the harnesses, instructions, and reviews that keep AI tools producing code that fits the system.

Technical Depth

• Strong recent experience as a hands-on senior engineer shipping and supporting a live production app.
• A deep understanding of software architecture, which matters more to us than any specific language. Our stack includes .NET/C#, TypeScript/Node, React, and SQL, and strong engineers from similar ecosystems will ramp up quickly. This includes:
  
  • object-oriented design, distributed systems, and event-driven architecture
  • asynchronous programming
  • relational databases and ORMs
  • automated testing
  • modern front-end and component architecture, including micro-frontends
• Experience with modern payment processing at scale. That means immediate API responses confirmed later by asynchronous webhooks, and the failure modes that come with them. It also means third-party rate limits, queuing and retries, and traffic spikes. Experience with Stripe, PayPal, or similar processors.
• A working knowledge of modern security practices for web and payment systems, and the instinct to spot a brittle or insecure design before it ships.

Collaboration

• You thrive on a tight-knit, highly communicative team that talks every day and jumps on quick calls to work through problems together.
