Your Day-to-Day
- Design, build, test, and maintain shared automation frameworks, internal services, and developer tools that serve multiple QA and engineering teams.
- Partner with QA and engineering teams to identify common testing needs and validate functionality, integration, reliability, performance, and usability across application and platform layers.
- Build and evaluate AI-assisted and agent-based testing capabilities using repeatable evaluations, human oversight, appropriate tool permissions, and fallback behavior for unreliable results.
- Develop and automate security testing for APIs, applications, and shared platforms, including authentication, authorization, access boundaries, and sensitive-data handling; partner with Security teams to validate findings and verify fixes.
- Test AI-enabled tooling for incorrect outputs, prompt injection, information exposure, unintended actions, and behavior when inputs or dependent services fail.
- Integrate reusable quality and security checks into CI/CD workflows, supported by actionable diagnostics, maintainable test data, clear documentation, and compatibility across supported environments.
- Investigate failures and production issues in shared tools and platforms, using targeted experiments and operational feedback to assess correctness, reliability, maintenance effort, and cost.
- Drive adoption through documentation, demonstrations, and mentoring while establishing shared testing practices and measuring improvements in test coverage, manual effort, and feedback time.
About You
- A Bachelor’s or Master’s degree in Computer Science, Engineering, or a related field, or equivalent relevant experience.
- Typically 6–8 years of experience in software testing, including 3+ years building test automation frameworks, quality engineering tools, or shared testing platforms.
- Strong programming skills, including Python, with experience applying software design, automated testing, code review, and maintainability practices to shared frameworks and tools.
- Broad hands-on testing experience across APIs, services, user interfaces, and platform integrations, including functional, integration, reliability, and performance testing.
- Hands-on experience building and evaluating AI-assisted testing solutions, including agent workflows, variable outputs, evaluation criteria, tool permissions, data protection, and failure handling.
- Experience delivering reusable tooling for multiple teams, with practical product thinking, clear documentation, stakeholder collaboration, and support for adoption and ongoing maintenance.
- Strong experience with cloud environments, CI/CD, infrastructure-as-code, and observability, including integrating test frameworks and quality checks into engineering workflows.
- Hands-on security testing experience covering authentication, authorization, API security, and sensitive-data handling, with the ability to automate checks, investigate findings, and collaborate with security specialists.
Bonus Points
- Experience owning internal developer or QA products through design, implementation, rollout, support, and continuous improvement.
- Experience evaluating AI safety and robustness, including prompt injection, unintended tool actions, and information leakage.
- Experience building shared capabilities for test data, test environments, quality reporting, or diagnostics.
- Experience establishing testing standards and enabling adoption of shared quality engineering practices across teams.
