• Design, execute, and maintain manual and automated test strategies for enterprise software applications in an Agile development environment • Review product requirements and functional specifications to define test scope, identify risks, and support sprint planning activities • Collaborate closely with software engineers, QA team members, and infrastructure teams to troubleshoot defects and resolve issues identified during testing • Develop and maintain repeatable QA test plans based on functional requirements, user workflows, system design documentation, and domain knowledge • Investigate test failures across multiple environments, including reviewing application logs, server logs, and database queries to support root cause analysis

• Lead validation and software testing activities across multiple platform delivery projects in regulated environments • Design, execute, and review functional, integration, regression, and performance test cases while ensuring traceability to requirements • Collaborate with developers, implementation managers, and cross-functional stakeholders to assess software changes, identify risks, and ensure product quality • Manage project timelines, testing priorities, defect tracking, and reporting for onsite and offshore testing activities • Contribute to continuous improvement initiatives by enhancing testing processes, tools, automation practices, and quality standards

Role Description We're looking for a QA Lead to join OpenMined, a nonprofit on a mission to build the public network for the world's non-public data — unlocking 1,000,000x more information across every scientific field and industry, and ensuring it stays open, equitable, and accessible to all. Our engineering team is brilliant and mission-driven, and we are looking for someone to join it who can collaborate across teams to build our quality function from the ground up. Our products are gaining customer traction and we strive to ensure reliability, security, and data integrity. This is not a traditional QA role. You won't sit in a separate team writing test scripts against specs. You'll be embedded with engineers — pairing on test design, reviewing architecture for testability, building frameworks and tooling, and creating the habits that make quality a natural part of how every engineer works. You'll set the organizational quality strategy: what gets tested, how deeply, at what layer, and what constitutes "done." The right person for this role is an engineer who chose to specialize in quality — someone who can read a codebase, identify the riskiest surfaces, design a testing strategy, write the tests, build the framework, and teach others to do the same. You earn credibility by contributing code and finding real bugs, not by writing policies and expecting compliance. If you're energized by building something from nothing, teaching through doing, and making an entire engineering organization better at shipping reliable software — we'd love to hear from you. Responsibilities - Own the delivery of engineering’s quarterly goals, ensuring consistent, high-impact delivery while effectively managing resources. - Work collaboratively in each product team’s codebase to access current test coverage, highest-risk surfaces, and its production readiness gap to produce a prioritized testing roadmap that engineers can see and execute against. - Establish testing patterns for a multi-language stack, implementing frameworks that make testing as easy as writing features. - Establish and socialize quality policies, minimum quality gates, and production-readiness standards collaboratively and iteratively with the product teams. - Spend regular time within each team’s workflow, pair on test design for complex features, review PRs for test quality, and make testing collaborative, not imposed. - Build and own what runs inside the CI/CD pipeline quality gates (testing suites, linting rules, reporting) supported by the Platform Lead. - Build automated PR checks and contributor CI gates to prepare for open-source contribution quality management. - Champion high-quality software delivery through the establishment of robust tools, processes, & methodologies, and by providing hands-on technical leadership via individual development contributions and code reviews. - Create technical documentation and processes that support high velocity and knowledge transfer. Qualifications - 5+ years of professional software engineering experience demonstrating capabilities to operate as an engineering peer within squads, not just as a testing specialist. - Python proficiency required; TypeScript and Go strongly preferred to ensure cross-team codebase understanding and ability to contribute beyond just test suites. - Has integrated testing frameworks from zero in at least two ecosystems. - Has defined quality standards and production-readiness criteria for an engineering organization. - Fluency integrating CI/CD quality gates into engineering workflows to encourage adoption and sustained use. - Has introduced testing culture to one or more teams in order to establish a team's capabilities and best practices. Benefits - US Healthcare Benefits: We offer healthcare benefits for employees located in the United States. - Mission-Driven Work: Be part of a 501(c)(3) nonprofit organization, focused on social impact rather than profit, offering the chance to make a meaningful difference in the world. - Open Source Contribution: Make a real impact by contributing to an Open Source project that benefits a broad community. - Collaborative Global Team: Join a dynamic, international team that values collaboration and diversity. - Flexible Work Hours: Enjoy the autonomy to structure your work hours around what best fits your life and productivity. - Fully Remote Work: Work from anywhere in the world—no office or commute required. - Results-Driven Culture: Thrive in an environment that values efficiency and results over bureaucracy. - Flexible Paid Time Off: Take the time you need with flexible vacation days, alongside recognition of local national holidays. - Competitive Compensation: Receive competitive pay, with equity in salary across different regions.
