Role
Who you are
- A Legacy of Impact: 20+ years of professional engineering experience, with a proven history of being the primary technical lead on multiple "business-critical" systems that have successfully scaled to millions of users
- Mastery of the .NET Ecosystem: Expert-level C# knowledge with a deep understanding of the .NET runtime, memory management, and high-performance optimizations. You are the mentor that Staff-level engineers look to for technical clarity
- Distributed Systems Visionary: Deep hands-on experience with the trade-offs of distributed state, eventual consistency, and global concurrency. You’ve successfully navigated major architectural shifts (e.g., Monolith to Microservices) at enterprise scale
- Strategic Partnership: Experience collaborating directly with VPs and Directors to translate a multi-year business roadmap into a technical execution plan. You can communicate technical risks to non-technical stakeholders with clarity and empathy
- Operational Excellence: A "Service Ownership" mindset. You have the "battle scars" from managing major production incidents and the foresight to build the resilience patterns that prevent them
- Force Multiplier: A track record of mentoring the next generation of technical leaders. You have raised the talent bar of an entire organization through architectural reviews, "Golden Path" creation, and engineering standards
- Education: B.S., M.S., or PhD in Computer Science, Physics, Engineering, or a related field (or equivalent elite-level practical experience)
- We are leaning into the future of AI-assisted development and love to work with engineers who do the same:
- AI as a Teammate: Hands-on experience leveraging AI coding tools (e.g., Claude, ChatGPT, Cursor, GitHub Copilot) to accelerate development, improve code quality, and streamline debugging workflows
- Engineering Judgment: Ability to critically evaluate and integrate AI-generated output, applying sound engineering judgment to ensure correctness, security, and maintainability
- AI Integration: Experience integrating LLM APIs (e.g., OpenAI, Anthropic) or AI services into production applications
- A Growth Mindset: Eagerness to stay current with the rapidly evolving AI tooling landscape and champion best practices for AI-assisted development within the team
- Champion an AI-Forward Culture: Set the standard for how AI-assisted development is adopted and practiced across the R&D org, establishing guardrails, sharing best practices, and inspiring engineers at every level to integrate AI tooling with craft and intentionality
- Being human isn’t about checking every box on a list. It’s about the experiences we have, people we meet, and the perspectives we share. So, if you have the skills but are hesitant to apply because of your background, apply anyway
What the job involves
- We are looking for a Principal Software Engineer to help us dream up and build the next generation of ServiceTitan
- In this role, you’ll be a foundational voice in our technical strategy, acting as a steward for the long-term health and evolution of our entire platform
- We’re looking for someone who enjoys thinking years ahead—designing the resilient systems that will support the trades for a decade to come
- This seat offers a unique balance of high-level organizational influence and a deep, ongoing connection to the craft; you’ll stay active in the codebase (approx. 40-50%) to help our squads navigate complex scaling puzzles and distributed systems challenges
- Your expertise in the .NET ecosystem will be the cornerstone of how we continue to innovate and raise the talent bar across the industry
- Define Global Architecture: Set the long-term vision for our .NET microservices architecture, ensuring it can support massive scale, AI-driven automation, and multi-tenant complexity
- High-Stakes Problem Solving: Act as the "special forces" for R&D, diving into the most critical performance bottlenecks or architectural failures and leading the team to a solution
- Influence the Roadmap: Partner with executive leadership to determine the "art of the possible," ensuring our technical capabilities stay ahead of market demands
- Set the Standard for AI: Lead the integration of AI-assisted development and LLM APIs into our production environment, establishing the safety, security, and quality guardrails for the entire org
- Community & Brand: Represent ServiceTitan Engineering in the broader .NET community through open-source contributions, speaking, or technical blogging, helping us attract the top 1% of talent
Our take
In the US, there's been a booming demand for home-service businesses, yet historically many of these trades were running with outdated software systems. That's where ServiceTitan comes in. Founded by friends who grew up around the trades, the company saw a clear gap and set out to give contractors the modern platform they desperately needed.
ServiceTitan's platform is designed specifically for the trades and brings together everything a contractor might need, in one handy system. By focusing on what trade-business owners actually need, it helps turn chaos into structure, giving visibility into operations, so owners can ultimately run their business better.
Now, ServiceTitan serves more than 11,800 trade customers and reported more than $10,000 in annualized billings and processes a huge volume of jobs on its platform. With a market that's still under-served by technology and a platform built to scale, the company is ready to grow even further.
