Role Overview
In this position, you'll focus on strengthening the foundation of software quality by creating robust testing systems and tooling used across engineering teams. Rather than testing individual features, you'll develop the infrastructure that enables consistent, automated validation at scale.
Key Responsibilities
- Design, implement, and maintain shared testing frameworks and services used company-wide
- Develop end-to-end test frameworks from the ground up, ensuring reliability and scalability
- Build and optimize CI/CD pipelines to support automated testing workflows
- Integrate mocking and service virtualization techniques to support isolated testing environments
- Lead technical research and proof-of-concept initiatives to evaluate new tools and approaches
- Partner with product and QA teams to identify gaps and enhance testing capabilities
- Create dashboards and analytics to monitor test stability, coverage, and performance trends
What You Bring
- At least 5 years of experience building test automation systems and developer tooling
- Strong coding skills in JavaScript or TypeScript at an intermediate level or above
- Experience developing backend services using NestJS and understanding of React component architecture
- Proven ability to build E2E testing frameworks independently
- Familiarity with testing libraries such as Jest, Mocha, Playwright, or Puppeteer
- Hands-on experience with mocking tools like Sinon, Nock, or MockServer
- Proficiency with Docker, including image management, networking, volumes, and docker-compose
- Experience configuring Jenkins pipelines and applying CI/CD best practices
- Working knowledge of NoSQL databases, particularly MongoDB
- Understanding of distributed systems including Kafka, Redis, and ClickHouse
- Ability to deliver production-grade tools, not just scripts
- Mindset for creating scalable, reusable solutions across teams
- Strong debugging skills and ownership of technical outcomes
Nice to Have
- Experience with contract testing using PACT or similar tools
- Background in quality analytics using ClickHouse or Grafana
- Track record improving CI efficiency and reducing flaky tests
- Work in test observability and quality metrics
- Experience conducting technical R&D and prototyping
- Familiarity with AI-based testing tools
- Knowledge of additional programming languages
