Full-stack Engineer

• Help define and build our quality engineering strategy across UI, API, data, and partner-facing surfaces.
• Improve and extend end-to-end test coverage for high-value workflows, with an emphasis on maintainability, signal quality, and developer confidence.
• Build deeper API-level validation for our GraphQL server and partner-facing REST surfaces, including contract testing, schema validation, regression coverage, and test data strategy.
• Work with product engineers to choose the right level of validation for each problem: unit, integration, API, contract, end-to-end, synthetic monitoring, observability, or exploratory testing when appropriate.
• Use AI and LLM-based tools thoughtfully to accelerate quality work, such as generating test cases, identifying coverage gaps, creating fixtures, analyzing failures, or building internal testing utilities.
• Know when not to use AI. A script, deterministic check, schema validator, or focused test runner is often the better answer.
• Help define what “done” means for features from a quality perspective, without becoming a bottleneck.
• Mentor engineers on writing testable software, designing stable interfaces, and creating systems that are easier to validate.
