Senior Quality Engineer — Remote, Testing Frameworks & CI/CD

Credo.AI Corp.; United States; Remote; USD 140,000 - 160,000; Full time

Job summary

Credo AI is seeking a Senior Quality Engineer to architect and champion high-quality software across Elixir, TypeScript, and Python codebases. In this enablement role, you'll design testing patterns, build tooling, and coach teams to own quality with confidence.

You'll work hands-on, crafting production-grade tests, strengthening CI/CD, and maturing automated testing practices in a fast-paced startup.

Qualifications

• 5+ years in software engineering, with significant time as a Software Engineer in Test or Quality Engineer.
• Strong software engineering fundamentals and production-quality code in Python, TypeScript, or Elixir.
• You've designed and implemented automated testing across unit, integration, API, and end-to-end layers.
• Built test automation frameworks, test harnesses, or CI/CD tooling that other engineers depend on.
• You use AI and agentic coding tools as part of your day-to-day engineering.
• You have strong influencing and communication skills: you move engineers toward better practices through evidence and credibility.
• You approach quality through a developer-experience lens and have the judgment to know where automation pays off and where it doesn't.
• You understand quality as an engineering discipline and prefer enabling teams to own it over centralizing testing.
• You operate well with autonomy in an early-stage startup environment.
• You have an interest in AI governance and responsible AI.

Responsibilities

• Partner with the Quality Engineering Lead to execute and evolve Credo AI's automated testing and quality engineering strategy.
• Compose, build, and maintain the testing frameworks, tooling, libraries, and supporting documentation that make high-quality software the default.
• Use AI and agentic coding tools to extend our testing framework, debug tests, and build AI-enabled workflows for test authoring.
• Advance automated testing maturity across our Elixir, TypeScript, and Python codebases, keeping our practices current with industry standards.
• Strengthen CI/CD pipelines and quality gates so engineering teams get fast, actionable feedback.
• Improve the developer experience around testing so that quality is easier to build in than to skip.
• Influence and coach engineers on testing strategy and effective use of frameworks and tooling, building shared ownership of quality.
• Participate in engineering reviews focused on testability, reliability, observability, and maintainability.
• Define and track quality metrics — automation coverage, test reliability, release confidence, and defect escape rates — and use them to prioritize the highest-impact work.
