Descrizione del lavoro

Ready to be a Titan?

We're looking for a seasoned technical leader who brings deep expertise, broad systems thinking, and the hands‑on drive to take complex ideas from design through delivery. You'll work at the intersection of architecture and execution - shaping the technical direction of company-wide initiatives while staying close enough to the code to make them real.We power thousands of home and commercial service businesses across the U.S. and beyond, helping them operate more efficiently through a platform that includes ML and AI-driven scheduling, dispatch automation, and real‑time operational workflows. We're quality‑minded, embrace modern engineering practices, and believe the best solutions come from engineers who are as invested in the craft as they are in the outcome. If that's how you think about your work, we'd like to talk.

What You'll Do

• Own & Deliver: Define the technical vision for your domain, plan 18+ months ahead, and see it through - writing code, leading implementation, and taking end-to-end accountability for quality and outcomes.
• Design & Build: Produce complete, production-ready system designs and then help build them. You write code and lead others in writing high-quality code. You drive and participate in major architectural decisions relating to scale, reliability, and security, and you're the person who makes those decisions real.
• Set the Standard: Be the reference point for engineering excellence. Your implementations, code reviews, and technical decisions serve as the model others learn from. You conduct architecture reviews, identify systemic risks, and introduce improvements that make the entire organization more effective at shipping.
• Discover & Generalize: Proactively identify opportunities to extract shared systems, define reusable patterns, and establish approaches that eliminate duplication and inconsistency across teams. You prevent the organization from diverging technically and build the foundations others build on top of.
• Empower: Coach and mentor Staff and Senior engineers in technical design, architecture, and systems thinking. You create opportunities for others to grow, run cross-team knowledge‑sharing sessions, and make the engineers around you demonstrably better.
• Shape Strategy: Partner with engineering leadership on roadmap and resource planning across company-wide initiatives. Surface and advocate for non-functional requirements - scalability, resilience, security, performance - and make sure they are reflected in how teams plan and execute. Align technical direction with ServiceTitan's business priorities.
• Recruit & Grow the Team: Assess candidates for senior technical roles, design interview plans, and make hiring recommendations. You help define and uphold the engineering bar.

What You'll Bring

• 15+ years of industry experience in large-scale enterprise web or SaaS applications, with 7+ years in senior IC roles designing and building systems used by other engineers at scale
• A proven track record of designing and shipping large-scale distributed systems - not just advising on them
• Deep expertise in at least one primary technology stack (e.g. C#/.NET, Java,C++ or equivalent), with the ability to quickly ramp up on and contribute to any technology in ServiceTitan's stack
• Strong command of distributed systems fundamentals: event-driven architecture, asynchronous programming, concurrency, fault tolerance, and performance tuning
• Hands‑on experience with cloud infrastructure (Azure, AWS, or GCP), including architecture, automation, and operational practices
• Solid grounding in data architecture: relational, NoSQL, vector databases, and distributed persistence
• Familiarity with AI/ML systems and LLM-based architectures - including orchestration, retrieval, and agentic patterns - aligned with the direction of ServiceTitan's platform
• Experience leading monolith-to-microservices or service-oriented migrations through to completion
• Strong command of modern engineering practices: Git, CI/CD, containerization (Docker), RESTful services, and observability tooling (e.g. Elasticsearch, DataDog, Prometheus)
• B.S., M.S., or PhD in Computer Science, Engineering, or a related technical field

Preferred

• A bias for execution: you are equally comfortable at the architecture whiteboard and in the codebase, and you hold yourself accountable for both
• The communication skill to make complex technical decisions legible to any audience - engineers, PMs, and leadership alike - in writing and in person
• A coaching mindset: you invest in the engineers around you and consistently leave teams, codebases, and architectures better than you found them
• Breadth across the engineering landscape with deep mastery in at least one area, and the intellectual curiosity to quickly develop credibility in new domains
• A habit of identifying risks, dependencies, and improvement opportunities before they surface as problems - and the ownership to address them
• Strong empathy for end users an
