• Build and evolve automated regression testing for our mobile applications and backend services, complemented by focused web end-to-end tests for critical customer journeys.

• Develop reusable testing frameworks, simulation tools, and test-data capabilities that help teams validate complex workflows efficiently.

• Integrate automated checks into CI/CD pipelines, improving test reliability, failure diagnostics, and feedback speed.

• Collaborate with engineers and product managers to make systems testable, define clear acceptance criteria, and prioritize coverage based on customer impact and risk.

• Shape and deliver the tribe’s QA automation roadmap, collaborating with QA peers and sharing reusable solutions and engineering practices across teams.

• Help engineering teams strengthen their ownership of quality, using defects and production insights to improve regression coverage.

• Complement automation with targeted exploratory testing to uncover risks and unexpected behavior.

• Evaluate and use AI-assisted tools for test development, maintenance, and failure investigation, critically reviewing their output for correctness and meaningful coverage.

• Strong software engineering and debugging skills, with experience building maintainable test frameworks, libraries, or internal tooling.

• Proven experience owning and improving test automation, from choosing an approach to making it reliable and useful for engineering teams.

• Strong backend and API testing experience, including validating data, integrations, and asynchronous workflows.

• Practical experience integrating automated tests into CI/CD, diagnosing failures, and reducing flaky tests.

• Sound testing judgment: you can identify important risks, choose the appropriate testing level, and balance coverage, execution speed, and maintenance effort.

• Clear communication and the ability to influence technical decisions and drive improvements across engineering and product teams.

• Experience with mobile test automation is particularly welcome. Web UI automation and experience in financial services are additional advantages.
