Senior Quality Engineer

About Caribou

At Caribou, we care about giving people financial freedom so they can focus on what’s most important to them. Today, less than two percent of Americans refinance their auto loans despite drastic increases in the cost of new and used cars. We see huge potential to help folks reduce their monthly auto expenses, as well as increase the predictability of those expenses over time. We do this by building technology to pair customers with community banks and credit unions, and ushering them through the process quickly. On average, our drivers save $159/month on their car loans while protecting their investment long term.

Caribou is led by leaders from the technology, automotive, and finance industries. We’re proud to be backed by a great team of investors, including QED Investors, Goldman Sachs, Moderne Ventures, Accomplice, Link Ventures, Motley Fool Ventures and others.

About the Role

Do you thrive on building testing platforms that make great tests inevitable? Do you believe that when engineers take the lead on testing their own work, the end result is a superior product? This may be the Quality Engineering role for you.

You'll join a team of 3 QE engineers using Playwright, Claude Code, and Harness to build the frameworks, tooling, and standards that make robust automated testing the path of least resistance. RSpec, Capybara, Playwright, Harness, Claude Code. You'll evolve and standardize how we use these tools across teams. Our goal: help Caribou reach DORA Elite performance by empowering engineers, not blocking or testing for them.

Interview Roadmap:

• Recruiter phone interview (45 mins)
• Coding assessment (25-60 mins)
• Hiring Manager video interview (60 mins)
• Final interview loop (combined 4 hrs scheduled across 1-4 business days):
  • System Design Interview (60 mins)
  • Project Delivery & Scope Interview (60 mins)
  • Product Partnership & Business Acumen Interview (60 mins)
  • Collaboration & Communication Interview (60 mins)

What You'll Do

• Guide framework evolution: Standardize patterns across our testing stack (RSpec, Playwright, Jest) and make architectural decisions about new tool adoption
• Build enablement infrastructure: Design factory patterns, data seeds, and service stubs enabling sophisticated testing in inner development loops without full integration
• Define quality standards together: Establish coverage thresholds, test suite structures for product types, and boundary metrics giving teams clear targets
• Optimize delivery pipelines: Integrate quality gates into CI/CD, balance performance and reliability, and analyze data to eliminate shipping bottlenecks
• Mentor and share best practices: Collaborate with teams on avoiding flaky tests, designing testable code, and building robust automated coverage
• Enable data-informed improvements: Analyze quality metrics (flaky tests, incidents, DORA) to identify systemic issues and facilitate process improvements

What We're Looking For

Experience with:

• Ruby on Rails applications
• Building or evolving test automation frameworks (RSpec, Capybara, Playwright, or similar)
• Production systems and collaborative debugging
• Translating quality metrics into actionable improvements (DORA metrics experience a plus)
• Mentoring or coaching teams to strengthen engineering practices

Nice to have:

• GCP, Docker, or containerized environments
• CI/CD pipeline optimization
• Interest in using AI to boost testing productivity

Ruby on Rails experience is required—most of our platform is Rails.

We know strong candidates rarely meet 100% of requirements. If you're excited about quality enablement and meet most of these, we'd love to hear from you. We encourage candidates from non-traditional backgrounds to apply.

Location and Flexibility

This role can be based out of our Caribou office in Denver, CO. Alternatively, this role may work remotely from a state where Caribou operates with a preference for the Chicago, IL, Denver, CO or San Francisco, CA markets. This role may require attendance at occasional in-person team meetings.

About You

You're a pragmatic, technically-minded leader who sees quality as shared responsibility. You're guided by data and possess the strategic vision to turn quality insights into engineering action. You communicate effectively with both technical teams and exec...
