About the role
We’re looking for a backend test automation engineer to help test systems that include AI-powered features. The work is focused on backend services, APIs, data flows, and integrations with third-party AI services.

What you’ll do

• Write and maintain automated tests for backend services and APIs
• Test AI-assisted features and services, including validating outputs and behavior
• Add AI evals into CI/CD pipelines to track AI quality over time
• Test async and event-driven workflows
• Validate data pipelines that mix structured data with text or documents
• Cover non-functional requirements like performance, scalability, and reliability
• Work closely with backend engineers and product to agree on what “good” looks like
• Contribute to CI checks, quality gates, and test reporting

What we’re looking for

• Solid backend test automation experience (3+ years)
• Strong experience with Python and JavaScript/TypeScript
• Hands-on experience with test frameworks (pytest, unittest, or similar)
• Experience testing APIs using tools like Postman, Requests/HTTPX, or similar
• Comfortable working with Docker
• Working knowledge of SQL for data validation
• Experience testing backend systems that include AI / ML / LLM components
• Experience testing non-functional aspects such as performance and scalability
• Experience working in a cloud environment (AWS, GCP, Azure, etc.)

Nice to have

• Experience building or maintaining AI evals
• Familiarity with LLM evaluation tools (DeepEval, Ragas, LangSmith, or similar)
• Experience dealing with non-deterministic systems (flaky results, hallucinations)
• Contract testing experience (Pact or similar)
• Some exposure to prompt engineering or RAG-based systems
• Familiarity with observability tools (CloudWatch, Kibana, Grafana, etc.)
• Basic security testing knowledge (OWASP, API security)
• Experience generating or working with synthetic test data
• Fluent English

We offer

• Competitive salary to be defined upon the interview results
• Full time REMOTE WORK
