Senior SDET

The Role We are looking for SDET to own quality engineering for the Simbian platform end-to-end. This role is not about executing test plans handed to you. It's about building the test infrastructure, strategy, and culture that makes quality a first-class property of everything we ship. You will design and build automated test frameworks from the ground up, integrate quality gates into the release process, and define what "release-ready" means for a multi-tenant, AI-powered security platform. You'll work closely with engineering, product, and security teams to embed testability into the platform from the start. What You'll Do Test Automation & Framework Ownership • Build and own the automated test framework covering UI, API, and integration layers for a multi-tenant web platform. • Design and implement test suites that are reliable, maintainable, and fast enough to run in CI. • Drive flaky-test reduction and own the health of the regression suite over time. • Establish test patterns and tooling that engineers can build independently. Test Strategy & Coverage • Design the test strategy for complex platform surfaces: multi-tenancy, RBAC, self-serve upgrades, and agentic workflows. • Define coverage targets and release-readiness signals that the team can trust. • Build and maintain regression suites that protect against regressions as the platform evolves rapidly. • Identify gaps in coverage proactively and prioritize closing them based on risk. CI/CD Integration & Quality Gates • Integrate test suites into CI/CD pipelines, so quality checks are part of every release, not an afterthought. • Build containerized test environments using Docker and Kubernetes to ensure consistency across dev, staging, and production. • Define and enforce quality gates that block bad releases and give engineers fast, clear feedback. Engineering Partnership & Defect Triage • Partner with engineers early - during design and implementation - to ensure features are built for testability. • Own defect triage: reproduce issues reliably, prioritize by impact, and track resolution. • Contribute to architectural discussions where quality and testability are at stake. Requirements You Might Be a Good Fit If You • Have 6-10 years of SDET or quality engineering experience, with a track record of building automation infrastructure, not just writing tests. • Think in systems: you design test strategies the way engineers design software. • Are comfortable operating independently - defining scope, making tradeoffs, and driving execution without a detailed spec. • Care about whether the product works for users, not just whether test coverage numbers look good. • Enjoy debugging hard, flaky, or environment-dependent failures and turning them into reliable signal. • Are comfortable in ambiguous, fast-moving environments where the product is changing as you test it. Must Have • 6-10 years of professional SDET or quality engineering experience. • Strong test automation experience in Python and/or JavaScript/TypeScript. • Hands-on experience with API automation (REST, GraphQL) and UI automation (Playwright, Selenium, Cypress, or equivalent). • Experience integrating test suites into CI/CD pipelines (GitHub Actions, Jenkins, or equivalent). • Experience with containerized test environments using Docker and Kubernetes. • Demonstrated ability to design test strategy independently - multi-tenancy, RBAC, or similarly complex surfaces preferred. • Strong debugging skills and ownership mindset. Bonus / Great to Have • Experience testing security products - SIEM, SOAR, EDR, NDR, or similar. • Experience testing LLM-powered or agentic systems - evaluating non-deterministic outputs, hallucination edge cases, or agent behavior. • Experience building evaluation frameworks or golden datasets for AI workflows. • Experience with observability and tracing tools to debug test failures in distributed systems. • Strong academic background in Computer Science or related field. Benefits • Build quality infrastructure for an AI-first cybersecurity platform from the ground up - no inherited mess. • Work at the intersection of AI, cybersecurity, and distributed systems. • Own the quality bar for the entire platform - your decisions shape what ships. • Work directly with founders, engineers, and security experts. • Be part of an early team where your work has an outsized, visible impact. • Ship fast, learn fast, and build systems that matter.
