The SDET will drive an engineering approach to test automation by extending and maintaining the Playwright/TypeScript framework for UI and API tiers. They will also design API-tier test coverage, implement test data strategies, and collaborate with development teams on integration and performance testing solutions.
The focus of this role is improving our cost-of-mistake curve by scaling our testing via automation. We are looking for someone who is resourceful to solve technical challenges such as scaling the test automation suite, test data management strategies, continuous integration as well as performance testing.
You are a test thinker first, software engineer second.
Omatic's product moves nonprofit data between systems, so the interesting bugs live in the data (formats, edge cases, transformation rules), not just the UI. Experience with API testing, data verification, integration testing, working with mocks and AI is preferred.
If you have a public code repository, share it with us! Tell us about one of your projects that you're most excited about or proud of. (It doesn’t have to be automation related.)
What you will be doing:
Effectively help drive an engineering approach to test automation at the level of integration and end-to-end.
Extend and maintain the Playwright/TypeScript automation framework (UI and API tiers), keeping it maintainable, extensible, and stable in CI.
Design and implement API-tier test coverage against Omatic's .NET REST services, including the data-plane services (Transform, Match, Route, Validate) and the configuration/runtime APIs.
Scope and build an automated test harness for Omatic's integration connectors, including strategies for testing against external CRM APIs (mocked, twinned, or sandboxed).
Facilitate discussions with development teams on the appropriate abstraction level to test at (unit, integration, system); collaborate on component and contract tests (Pact pilot).
Use and improve AI-assisted quality workflows (automated triage, change-driven test scoping) as force multipliers, with clear understanding of its outputs.
Implement a test data strategy that allows repeatable and relevant tests.
Evaluate and help architect performance testing solutions.
What you will bring:
Be able to think and act experimentally.
Be able to articulate and demonstrate various test techniques and test heuristics.
Be able to effectively collaborate with development and infrastructure engineers.
Demonstrated experience building and maintaining test automation in a modern web framework (Playwright strongly preferred) with TypeScript/JavaScript proficiency.
Demonstrated experience testing RESTful APIs directly (not only through a UI).
Demonstrated experience keeping automation stable in CI (flake diagnosis, synchronization, environment issues)
Ability to apply concepts of risk, cost/value trade-offs, and prioritization to what gets automated (and what doesn't).
High self-initiative and self-motivation; sustained track record of peer-reviewed contributions.
Ideal: C#/.NET familiarity (our services under test).
Ideal: contract testing experience (Pact or similar).
Ideal: experience with mocking/service-virtualization strategies for third-party APIs.
Ideal: thoughtful use of AI tooling in testing workflows.
