Senior Software Engineer

ServiceTitan is a software company building products for contractors. The Senior Software Engineer will help create a new Exteriors product area covering roofing, siding, windows, and gutters, owning features across the sales-to-production workflow. The role involves full-stack development, technical design, debugging, architecture evolution, and collaboration with product and engineering stakeholders.

Responsibilities:

• Own significant, well-defined pieces of the full sale-to-production lifecycle end to end — from technical design through shipping and iteration
• Design and build full-stack features across our C#/.NET backend and React/TypeScript frontend
• Partner closely with product managers, designers, and other engineers to translate the needs of roofing, siding, window, and gutter contractors into shipped software
• Make sound technical decisions within your area of ownership, escalating and collaborating with senior engineers and your lead on cross-cutting or architecturally significant choices
• Write clean, well-tested, maintainable code, and hold that same bar in code reviews for your teammates
• Debug and resolve complex issues across the stack, including performance and reliability problems in a distributed systems environment
• Contribute to technical design discussions and help evolve the architecture of a fast-growing product area
• Communicate clearly with engineers, product managers, and other stakeholders about progress, tradeoffs, and risks

Requirements:

• Equivalent of 8+ years of professional software engineering experience, including building production systems used by real customers
• Strong full-stack ability, with hands-on experience in C#/.NET and React/TypeScript (or comparable strongly-typed backend and modern frontend frameworks) — comfortable moving across the stack as the work requires
• Solid understanding of SQL databases (Microsoft SQL Server or equivalent) and how to design efficient, reliable data models
• Working knowledge of distributed systems and microservices architecture
• Proficiency with Git, unit testing, debugging, and performance profiling
• Strong communication and technical writing skills — you can explain your reasoning clearly to both engineers and non-engineers
• Comfort with ambiguity: this is a newly-formed squad building new product surface area, so priorities and requirements will evolve as we learn from contractors in the field
• A genuine interest in understanding the contractor's workflow (sales and production) well enough to build software that actually solves their problems
• B.S., M.S., or equivalent practical experience in Computer Science, Engineering, or a related technical field
