Agentic Software Test Engineer — TRACE

At Trane Technologies® we Challenge Possible. Our brands – including Trane® and Thermo King® – create access to cooling and comfort in buildings and homes, transport and protect food and perishables, connect customers to elevated performance with less environmental impact, dramatically reduce energy demands and carbon emissions, and innovate with a better world in mind. We boldly challenge what's possible for a sustainable world.

The Agentic Software Test Engineer — TRACE sits on the Customer Driven Solutions (C.D.S.) Team and runs the agentic testing organization for TRACE — the building energy simulation platform that powers HVAC load calculations, equipment sizing, and ASHRAE-compliant reporting for engineers worldwide.

You direct a team of AI testing agents across a multi-repo .NET / Blazor codebase, working shoulder-to-shoulder with the TRACE software developers as their dedicated QA partner. You're the captain of the agent crew and the quality voice the developers trust — coaching the agents, raising the bar, and putting your name on the work that ships.

This is a hands-on engineering seat; you direct the agent crew; you partner with the humans.

·
Direct the agentic testing team — define agent personas, dispatch patterns, and human-in-the-loop checkpoints for QA across TRACE.

·
Author the prompts, context contracts, and knowledge bases that drive the agents through test plan generation, regression authoring, defect triage, exploratory testing, and accessibility sweeps.

·
Build evaluation harnesses that measure agent output quality — false-positive rates on bug reports, regression coverage drift, flaky-test detection, eval-vs-production divergence — and tighten the loop sprint over sprint.

·
Curate what the agents produce — test plans, automated scripts, exploratory findings, regression results — and ship the best of it into the engineering pipeline with your stamp on it.

·
Hunt bugs through manual, automated, and agent-driven methods, and verify every agent-surfaced finding before it reaches the development team.

·
Own TRACE's quality posture as the SME on HVAC simulation correctness, ASHRAE compliance reporting, Energy Plus integration behavior, and cross-repo regression risk.

·
Partner with developers and Product Owners on test coverage decisions, release readiness, and quality strategy.

·
Run regression, functional, and data tests across the .NET 10.0 backend, Blazor frontend, PostgreSQL schema, and Energy Plus calculation engine.

·
Design adversarial verification workflows — parallel agents that try to refute a test result before it's trusted.

·
Curate the agent learning loop — capture recurring failure patterns, encode them into spec rules, and feed them back into agent knowledge bases so the same defect class is caught earlier next sprint.

·
Translate customer-impact reports into agent-runnable test scenarios and explain quality posture to non-technical stakeholders without hand-waving.

· 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…
