Staff SDET

You will be the senior quality engineering owner for Arintra's productivity team. The role is not limited to writing tests; you will define how quality is built into AQM, Abacus, and Harmony. You will own test strategy, CI/CD quality gates, accuracy regression checks, SLO thinking, quality metrics, and the testing standards that engineering teams follow. You will also mentor the SDET-1s and partner closely with AI agents and DevEx engineers.

The core responsibilities for the job include the following:

Quality Strategy and Architecture:

• Define and own the testing pyramid across unit, integration, component, E2E, contract, and accuracy regression layers.
• Set coverage and quality gates by repo/component risk tier and drive engineering alignment.
• Define testable-by-design patterns such as dependency injection, interface boundaries, and shift-left test requirements

CI/CD Quality and Accuracy Gates:

• Own CI/CD quality gates, including static analysis, coverage enforcement, component/E2E checks, and accuracy regression checks.
• Partner with DL/engineering teams to make model accuracy regression a first-class release gate.
• Define fast vs. full regression strategies and thresholds for PRs vs. main branch releases.
• Ensure quality gates are visible, stable, and trusted by engineering teams.

Metrics, SLOs, and Reliability:

• Build and own quality metrics: coverage, defect escape rate, accuracy per specialty, alert volume, code quality score, and reliability trends.
• Define SLOs for AQM accuracy, Abacus processing reliability, and Harmony latency with clear error budgets and alert thresholds.
• Lead defect retrospectives and ensure every escaped defect results in a test, monitor, or process improvement.
• Partner on canary accuracy monitoring, incident-response quality bar, and SRE-AI feedback loops.

Leadership and Mentorship:

• Mentor SDETs through structured reviews, code reviews, and development planning.
• Influence engineers across squads without relying on reporting authority.
• Champion quality is built in, not tested in, across engineering.
• Partner with the AI Agents Engineer to evaluate and improve the Testing Agent.

Requirements:

• 7+ years of SDET/QA engineering experience, including at least 2 years at the staff/principal/lead level or an equivalent scope.
• Strong hands-on automation depth across at least two test frameworks, including pytest and/or Java-based frameworks such as JUnit/TestNG.
• Strong Java and Spring understanding; able to read application code, identify testability issues, and review test design meaningfully.
• Hands-on CI/CD quality pipeline ownership; has written CI YAML, configured required checks, and debugged pipeline/test infrastructure issues.
