Staff SDET
Description
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.
- Experience with static analysis and quality tools such as SonarQube, mypy, pylint, Checkstyle, SpotBugs, or equivalent.
- Experience with contract/component testing for distributed services.
- Experience with Docker and containerized test environments.
- Experience defining test strategy from scratch for inherited systems and driving remediation using data.
- Experience with ML/model regression or accuracy evaluation, or strong adjacent experience in data-heavy correctness testing.
- Strong SQL and BigQuery ability for defect analysis, trend rollups, accuracy/reliability correlation, and dashboard validation.
- Excellent leadership communication: can present quality health to engineering leadership with data and clear recommendations.
Nice to Have:
- Healthcare, medical coding, or other regulated/high-accuracy domain experience.
- Experience with Playwright/Selenium and large E2E suites.
- Experience with SLOs, error budgets, chaos/fault injection, or reliability testing.
- Experience integrating AI-assisted testing or code review workflows.
- Experience building or owning quality dashboards in Looker, Metabase, Grafana, or similar.
