Agentic Software Test Engineer

Trane Technologies

La Crosse, WI 54601

5+ years in software quality assurance, with a real track record of shipping tested software.
1+ year hands-on with LLM-based agents, AI coding assistants, or multi-agent systems in a production or near-production workflow.
Strong test-design instincts across unit, integration, system, functional, and exploratory layers; comfortable owning test plans, defect lifecycle, regression strategy, and release gating.
Hands-on experience with AI coding agents (Claude Code, Cursor, Copilot Workspace, or equivalent) and the Anthropic / OpenAI APIs.
Working knowledge of prompt engineering, structured outputs (JSON Schema), tool use, and multi-agent orchestration (parallel/pipeline/judge-panel/adversarial-verify).
Comfort designing evals and treating eval results as a first-class quality metric.
Bias toward human-in-the-loop verification — never trusting agent output blindly.
Ability to read and modify production code in C#, Python, or JavaScript — not just test code.
Experience with GitHub Actions testing pipelines.
Working knowledge of Jira (or equivalent) and testing tools like Playwright, BUnit, xUnit / NUnit.
Strong written and oral communication; able to explain agent behavior, eval results, and quality posture in plain language.
