Core Responsibilities

  • AI-Driven Automation Infrastructure: Design, build, and scale end-to-end automated testing frameworks, integrating AI agents for autonomous test generation, maintenance, and self-healing suites.
  • Framework Architecture: Develop and maintain scalable test tooling and infrastructure across backend APIs, distributed cloud architectures, and web/mobile interfaces.
  • AI & LLM Validation: Establish testing strategies for features powered by Large Language Models (LLMs), focusing on prompt regression, hallucination detection, bias evaluation, and determinism.
  • Code & Quality Reviews: Act as a technical subject matter expert (SME) for code hygiene, guiding design reviews, and evaluating testability and architectural health.
  • Test Strategy & Coverage: Define and drive test strategies spanning functional, regression, API, performance, load, contract, and chaos/resilience engineering.
  • CI/CD Integration: Integrate automated test suites and infrastructure into continuous integration and deployment pipelines (e.g., GitHub Actions, Jenkins, Azure DevOps, GitLab)
  • Debugging & Root Cause Analysis: Investigate complex system failures, performance bottlenecks, race conditions, and production issues.
  • Cross-Functional Collaboration: Partner with software developers, product managers, and DevOps teams to align acceptance criteria and improve system observability.
  • Mentorship: Guide junior and mid-level engineers while advocating for a strong quality-first culture.

Key Requirements & Skills

  • Experience: Typically 5 to 9+ years of combined experience in software development, backend engineering, or specialized SDET/test engineering roles.
  • Programming Languages: Proficiency in languages such as Python(highly preferred for AI workflows), Java, TypeScript.
  • Automation Frameworks: Hands-on experience with modern tools like Playwright, Selenium, Cypress, or TestNG/JUnit.
  • Cloud & Distributed Systems: Familiarity with cloud platforms (AWS, GCP, Azure) and containerized or distributed stacks (Docker, Kubernetes, Kafka, Redis, Cassandra).
  • Infrastructure & Monitoring: Experience using observability and logging tools (e.g., Grafana, New Relic, Elasticsearch)

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
