About Symitri
Symitri is a performance marketing technology company built on an uncompromising promise of privacy and data protection. We help advertisers achieve stronger outcomes using first-party data unavailable in the bidstream, while our privacy-first infrastructure keeps sensitive data protected at every step.
The Role
We’re looking for a QA Automation Engineer to take ownership of quality across Symitri’s backend systems and browser-based integrations. You’ll lead the development of test automation for B2B APIs and JavaScript components running in third-party environments, ensuring performance, reliability, and SLA compliance. Working closely with engineering and product teams, you’ll design the core test suite, drive QA best practices, and embed quality checks directly into our CI/CD workflows.
Key Responsibilities
Test Automation & Engineering Partnership
- Build and maintain automated test suites for RESTful and gRPC APIs
- Develop browser-based testing for JavaScript behavior in third-party and sandboxed environments
- Partner with senior engineers to design and own Symitri’s end-to-end QA strategy
- Integrate testing into CI/CD pipelines and sprint workflows
Performance & Reliability Monitoring
- Define and enforce latency SLAs across key endpoints and integration points
- Analyze test results and production telemetry to detect regressions early
- Create tools and scripts for validating asynchronous and event-driven flows
Documentation & Quality Advocacy
- Write, manage, and organize test cases using TestRail or similar tools
- Maintain coverage reports, test plans, and data requirements documentation
- Act as a quality advocate across agile sprint cycles, surfacing edge cases and usability risks early
What You’ll Bring to Symitri
- 3+ years of experience in QA automation or software testing roles
- Strong background in testing APIs, particularly in server-to-server integrations
- Hands-on experience testing JavaScript execution in-browser across real-world use cases
- Experience working with developers to embed test coverage early in the lifecycle
- Confidence working with tight feedback loops in agile product teams
Tech Stack & Tools You’ll Use
- Automation Frameworks: Cypress, Playwright, Postman, JUnit
- Languages: JavaScript, TypeScript, Python
- Protocols & Tools: HTTP, REST, gRPC, JSON, browser dev tools
- CI/CD & Orchestration: GitHub Actions, Jenkins, CircleCI
- Performance Testing: k6, JMeter, or Gatling
- Monitoring: Datadog, Grafana, Prometheus (nice to have)
- Version Control: Git, branching workflows
- Web Fundamentals: Cookies, localStorage, CORS, sandbox constraints
What Success Looks Like
- You’ve built a robust automation suite that prevents regressions and boosts release velocity
- SLAs are consistently met, and latency issues are caught pre-deployment
- Your test coverage anticipates real-world complexity in both APIs and browser contexts
- You’re a go-to voice for quality assurance across the engineering and product teams
