About The Position

Ready to be a Titan? Over 50,000 people depend on ServiceTitan’s software to run their daily business operations. You will be a crucial part of the APEX Engineering team, responsible for the technical evolution of our product, platform, and tooling ecosystem. We are a rapidly growing, reliability-driven organization passionate about automation, engineering productivity, and modern technology. We are looking for a technically capable, forward-looking engineer who can balance rapid iteration with long-term strategic thinking. In this role, you won't just be building software; you will be pioneering AI innovation, building platforms that ensure Trust in AI, and spearheading our performance engineering initiatives. If you are comfortable with ambiguity, love solving complex problems on the Microsoft .NET platform, and want to build best-in-class tools adopted across the entire company, you might find your perfect fit here. What you’ll do: As a Senior Software Engineer in APEX, you will own critical tooling and strategy from the local machine through to production, providing observability and fostering a quality mindset across the board. Expect a roughly 70% development and 30% architecture/mentorship/requirements split. Pioneer AI Innovation & Trust: Drive the integration of AI within our engineering tooling and product features. You will build transparent, reliable systems that champion "Trust using AI," ensuring our automated platforms are both cutting-edge and deeply secure. Build the Performance Platform: Architect, develop, and scale our performance testing platform from the ground up. You will define technical SLAs, build out capacity planning tools, and establish comprehensive production performance monitoring to guarantee system reliability at scale. Architect & Implement: Design and implement user-facing features and shared services end-to-end, working closely with product managers, designers, and architects to guarantee thorough system-level checkpoints. Evolve Test Productivity: Build, improve, and speed up testing frameworks, libraries, and shared services. Enable engineering teams to self-service across internal tooling, public cloud (Azure/AWS), and Kubernetes. Evaluate & Mentor: Assess third-party tooling, educate peers on best practices, and mentor engineers to elevate the team's overall velocity and success.

Familiarity with Object-Oriented Programming, Python, and front-end frameworks (HTML5, JavaScript, React).
Proven ability to build horizontally scalable test services.
Deep expertise in performance testing, load generation, defining system SLAs, and utilizing production observability/monitoring tools.
Experience building, testing, or integrating AI-driven tools, with a strong understanding of how to build reliable, trustworthy guardrails around AI implementations.
