Sr./Lead QA Automation Engineer – AI Agent

Why This Role Is Important to Us:

We are looking for a QA Automation Engineer to own and evolve the quality strategy for this product. The product's risk sits in cross-service behavior, where agent runs, tool calls, external integrations, and cloud infrastructure meet. The role blends hands-on manual and exploratory testing of new features and AI behavior with designing and building the automated test system (acceptance, integration, contract, and post-deployment validation) that lets the team ship quickly without breaking critical engineering workflows.

What You Will Be Responsible For:

As a QA Automation Engineer on this team, you will:

Test Strategy and Hands-on Testing:

• Define and own the product's test strategy across unit, functional, integration, acceptance, post-deployment, and exploratory testing.
• Perform hands-on manual and exploratory testing of new features, AI-agent behavior, and edge cases before and alongside automation.
• Design approaches for testing non-deterministic AI/LLM behavior, tool-use correctness, and prompt regressions.

Automated Coverage:

• Build browser-level acceptance tests that cover key user journeys end to end, from the UI down to persistence and background processing.
• Create validation for MCP endpoints, including authentication flows, client compatibility, and tool schemas.
• Design contract and replay-based tests for critical external integrations where live systems are slow, expensive, or unstable.
• Strengthen test coverage for the highest-risk execution surfaces: sandboxed code execution and the agent's remote sessions on user machines.

Release Confidence and Test Infrastructure:

• Add post-deployment smoke tests that catch environment, configuration, and identity failures, giving rollback confidence.
• Introduce failure-injection scenarios (service restarts, network loss, expired tokens, rate limits) to prove the product degrades gracefully.
• Improve test data, fixtures, fake connectors, and CI test categorization; manage flaky tests and keep pipelines fast and trustworthy.

Collaboration and Quality Leadership:

• Partner with engineers to make features testable and define acceptance criteria before implementation; mentor the team in testing practices.
• Monitor quality signals from CI, static analysis, telemetry, production incidents, and user feedback, and build release-readiness reporting.

What We Value:

• You can see yourself contributing and thriving in the position described above. We expect you to be strong in several of the following and interested in learning the rest.
• Bachelor's or Master's degree in Computer Science, Engineering, Mathematics, or a related field.
• 6+ years of experience in quality engineering / test automation for complex web and API platforms.
• Strong C#/.NET test development skills: xUnit/NUnit-style frameworks, mocks and fakes, test fixtures, and CI integration.
• Solid experience with API and integration testing, including authentication and distributed-system failure modes.
• Experience with browser automation such as Playwright, Selenium, or equivalent.
• Strong manual and exploratory testing skills, and the ability to design test strategies rather than only execute predefined cases.
• Understanding of CI/CD pipelines, test categorization, flaky-test management, and post-deployment smoke testing.
• Ability to investigate failures using logs, traces, telemetry, screenshots, and reproducible minimal scenarios.
• Experience testing AI/LLM products, agentic workflows, streaming responses, or other non-deterministic behavior is a strong advantage.
• At least 1 year of hands-on experience using AI coding agents such as Claude Code or Codex in your daily work.
• Familiarity with open-source agents (e.g., OpenCode, Hermes, OpenClaw, or similar) and how they behave in practice.
• Passion for the AI space and the flexibility to try new technologies: you stay on top of market trends and bring the ecosystem's best practices (better memory, context management, and agent autonomy) into how we build and test the product.
• Working knowledge of Linux and containerized environments (Docker), enough to test and investigate sandboxed code execution, is a strong advantage.
• Experience with Test containers, contract testing, Azure identity, or Windows automation is a plus.
• Proven ability to lead quality direction, influence engineers, and raise the testing bar across a team.
• Excellent English communication skills, both written and spoken.

Benefits:

• Global hybrid work policy: We ask you to work 2 days a week from the office. If you choose, you can work remotely the other days.
• Culture: Inclusive and diverse company culture.
• Work-life balance: We believe that an equilibrium between professional responsibilities makes us all the best version of ourselves, both in private life and as colleagues in the workplace.
• Empowerment: We believe that all voices are valuable and must be heard. You will be involved in shaping our work processes.
• Career and Growth: SimCorp offers opportunities for professional development, with an individual approach to support the direction you want to take.
