Requirements
• Solid programming fundamentals — you can write clean, maintainable test code and contribute to the codebase directly, not just file bug reports. • Hands-on experience owning or significantly contributing to a release process — you understand what it takes to ship software reliably and what breaks when that process is weak. • Experience designing or evolving CI/CD pipelines: what to gate on, what to automate, and how to keep builds fast and signal-to-noise high. Familiarity with GitHub Actions or similar tooling is a plus. • Experience writing automated tests across multiple layers: unit, integration, and end-to-end. Familiarity with TypeScript is a plus. • Strong analytical instincts for breaking down a user journey into the cases that actually matter — you think about what can go wrong, not just what's supposed to go right. • Familiarity with GCP or similar cloud platforms is a plus. • Excellent written communication — you can articulate a test plan, document a bug precisely, and explain a testing principle to an engineer who's never thought about it before. • Self-directed and systematic: comfortable working asynchronously across time zones, managing your own priorities, and pushing work forward without waiting for direction. • Experience testing API-driven or payments products is a plus; familiarity with KYC/KYB flows, webhooks, or financial compliance surface areas is a bonus.
Responsibilities
• Own the release process — you're the last line of defense before code ships. That means uphold release criteria, coordinating across engineering, and making the call on whether something is ready to go. • Shape the CI/CD pipeline alongside engineering — defining what gates matter, what signals are trustworthy, and what tooling gives the team confidence at every stage from commit to deploy. • Work with product and engineering to translate user journeys and acceptance criteria into thorough, well-structured test cases — covering happy paths, edge cases, and failure modes across an expanding product surface area. • Execute those test cases continuously as the platform grows, catching regressions and surfacing bugs before they reach customers. • Collaborate with engineering to improve platform testability — better interfaces for test isolation, cleaner seams between components, and systems that make verification straightforward rather than painful. • Build and maintain automated test suites that scale with the product, reducing the manual burden over time and making quality a property of the delivery pipeline rather than a gate at the end of it. • Fundamentally raise the testing bar across the engineering team — through code review, documentation, pairing, and pragmatic guidance on what good testing looks like at each layer of the stack.
Benefits
• We sit at the intersection of crypto infrastructure and regulated finance — at the moment those worlds are finally converging. That means: • The window is now: For the first time in decades, the backbone of cross-border payments is being rebuilt. Legacy systems are fading, stablecoins are entering institutional finance, and the next settlement layer is being shaped right now. We're building it alongside the institutions that will run it, not around them. • High ownership, no playbook: This is early-stage work. You’ll be making decisions, building processes from scratch, and setting the direction instead of just following one. We’re looking for people who don’t wait for instructions, but jump in and figure things out. • Adaptability is the job: Strategy pivots here aren't failures, they're how we stay ahead of a fast-moving market and that’s our strength. • Real traction, real stakes: SpherePay is live and trusted by 200+ businesses. SphereNet is in active development with banks and regulators across 18 jurisdictions and counting. There’s real demand, real momentum, and a huge opportunity to shape what comes next. • We may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses. These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans.
