About the Role
We're hiring Senior and Staff SDETs to embed across our product teams and raise the bar for quality engineering at Galaxy. You'll work on systems that move real value — crypto and fiat across institutional-grade platforms. The problems are complex, the stakes are high, and the teams are small enough that your work will have outsized impact.
This isn't a "write tests and throw them over the wall" role. You'll shape how your team thinks about quality — designing automation strategies, influencing architecture for testability, and driving reliability across the stack. Depending on your strengths and interests, you'll be placed on one of our product teams: Lending, Trading, Operations, Custody, Settlement, Staking, Derivatives, or Retail (mobile apps on Android and iOS).
We're looking for excellent engineers first — we'll find the right seat together.
What You'll Do
- Design, build, and maintain test automation frameworks and suites for APIs, backend services, web and mobile UI (Android/iOS), and blockchain-integrated components.
- Define and drive the quality strategy for your product team — test planning, coverage analysis, risk assessment, and release readiness.
- Partner closely with developers, DevOps, and product managers to shift quality left and influence system design for testability.
- Analyze test results, production incidents, and system behavior to identify patterns and drive systemic improvements.
- Build and maintain CI/CD-integrated test pipelines that give teams fast, reliable feedback.
- Leverage AI-assisted development tools to accelerate test creation, code analysis, and automation workflows.
- Contribute to performance testing, security validation, and observability practices.
- Mentor other engineers on testing practices, code quality, and automation design.
Additionally at Staff level:
- Set technical direction for quality engineering across multiple teams or domains.
- Drive cross-team alignment on testing standards, frameworks, and tooling.
- Identify high-impact quality problems before they're obvious and build consensus around solutions.
- Act as a trusted technical
