QA Engineer

About us

Relay is a cross-chain payments protocol that provides instant, low-cost cross-chain bridging, swaps, and transactions. We're the fastest and cheapest way to bridge and transact across chains, serving over 5 million users who have completed 59+ million transactions with $6+ billion in volume across 85+ chains.

Our company mission is to make transacting across chains as fast, cheap, and reliable as online payments. We are building the core infrastructure to abstract chains from end user payments, enabling the next billion users to experience the benefits of blockchain without the UX burdens.

About the role

As we expand to new chains, onboard more integrators, and migrate toward microservices, we need dedicated QA coverage on each product team, not a shared function stretched thin.

You'll embed with one of our product teams and own their QA end to end: running the release gate from staging, extending the automated test suite, and working closely enough with engineers that you know what's shipping before it ships. You'll also contribute to active QA infrastructure projects, including AI-assisted integrator test suites and incident back-testing.

What you'll do

Own QA for your product team

• Run the release gate from staging: review what's merged, execute the test suite, and sign off before anything goes to production

• Stay embedded with engineers on your team so you're never catching problems cold at the gate

• Define what "good coverage" looks like for your domain and close the gaps yourself

Build and maintain the test suite

• Write and maintain automated tests for your team's slice of the codebase

• Use AI tooling to accelerate test generation from usage profiles and keep coverage current as the product evolves

• Participate in the quarterly refresh process to keep suites aligned with real behavior

Contribute to QA infrastructure projects

• Help build integrator-specific test suites with usage data to target the workflows that matter most to our top customers

• Analyze reverted or incident-causing PRs, identify where better tests or process could have caught them, and help implement non-blocking CI flags

• Bring findings back into the test suite and tooling, not just into reports

Push QA tooling forward

• Incorporate AI tools into QA workflows, building on what the team has already started

• Work with QA team to improve the AI-powered PR review process and broader automation

About you

• You easily write test code and contribute to owning and evolve a codebase

• You're comfortable reading PRs, reasoning about code you didn't write, and asking good questions when you need context

• You know what a staging gate is and how to operate one

• You don't wait to be told what to test; you figure out what matters and go build coverage

• You communicate clearly and build trust with your fellow engineers easily

• You're curious about AI tooling and already thinking about how it changes what's possible in testing

• You're excited about crypto/blockchain and the unique demands of its infrastructure

Skills and abilities

• Must-have

  • 4+ years of QA engineering experience with automated test suites (not manual testing)

  • Experience owning QA in a CI/CD pipeline

  • Comfortable reading and reasoning about code, even in an unfamiliar codebase

  • Strong written communication and ability to work cross-functionally with engineers

  • Track record of working autonomously without close management

  Nice to have

  • Experience with AI-assisted testing tools

  • Familiarity with Datadog or similar observability tooling

  • Blockchain / crypto domain knowledge

  • Early-stage startup experience

What we offer

• Competitive base salary

• Equity package

• Comprehensive health benefits

• Unlimited PTO policy with encouraged minimum

• Remote-first culture with emphasis on collaboration, communication, and flexibility
