Proof of work

The team

The Pro team is responsible for everything to do with the trading backend services such as the matching engine, market data gateways, internal and external APIs, and various other trading services. The team is located globally and responsibilities are split into sub-teams, working with various tech stacks. Our teams code in Rust and work agile around the globe. Recently, the team played a critical role in scaling Kraken's trading infrastructure.

The opportunity

  • Create comprehensive test plans before feature development, defining manual and automated testing strategies.

  • Perform hands-on manual testing during development cycles to validate new features before automation.

  • Balance manual exploratory testing with automation to catch edge cases that scripts might miss.

  • Collaborate with engineers, product managers, and designers to define QA processes for a mission-critical trading platform.

  • Lead automation initiatives end-to-end: strategy, implementation, CI/CD integration, and scaling coverage.

  • Drive performance, security, and accessibility testing to deliver a top-tier experience for traders.

  • Proactively document, report, and triage bugs to improve release quality and velocity.

Skills you should HODL

  • Strong programming skills in Python, Rust or another automation-oriented language.

  • Trading knowledge and experience - understanding of order types, trade execution, margin trading, and general financial markets (we'll support deepening your expertise, but foundational knowledge is essential).

  • Proven ability to design comprehensive test plans before implementation, identifying what should be manually tested vs. automated.

  • Experience designing, implementing, and maintaining test automation frameworks on complex applications.

  • Strong manual testing skills and ability to think creatively to uncover edge cases and unexpected bugs.

  • Solid understanding of QA principles, including exploratory testing, regression testing, and bug tracking.

  • Comfort with CI/CD integration and automation at scale.

  • Detail-oriented mindset with a passion for building high-quality software and ability to think outside the box.

Unless a specific application deadline is stated in the job posting, applications are accepted on an ongoing basis.

Please note, applicants are permitted to redact or remove information on their resume that identifies age, date of birth, or dates of attendance at or graduation from an educational institution.

We consider qualified applicants with criminal histories for employment on our team, assessing candidates in a manner consistent with the requirements of the San Francisco Fair Chance Ordinance.

Kraken is powered by people from around the world and we celebrate all Krakenites for their diverse talents, backgrounds, contributions and unique perspectives. We hire strictly based on merit, meaning we seek out the candidates with the right abilities, knowledge, and skills considered the most suitable for the job. We encourage you to apply for roles where you don't fully meet the listed requirements, especially if you're passionate or knowledgable about crypto!

We may ask candidates to complete job-related skills or work-style assessments as part of our hiring process. These assessments are designed to evaluate competencies relevant to the role and are applied consistently across candidates for similar positions. Assessment results are considered alongside other relevant information, such as experience and interviews, and are not the sole basis for any employment decision.
