As a Senior Staff Software Engineer, iOS, you’ll be the apex technical leader of this effort: setting the long-term technical vision for our entire mobile organization, driving cross-company architectural alignment, and pushing Apple’s ecosystem to its fullest potential to create lasting product differentiation
This is an organization-defining role. You’ll establish the engineering philosophy that guides our iOS platform for years to come—shaping how we build, how we scale, and how we grow our engineers
You’ll operate at the intersection of deep technical mastery and broad organizational influence, working across product, design, data, and backend leadership to deliver outcomes that transform how tradespeople run their businesses
Define and own the multi-year technical vision for ServiceTitan’s iOS platform—establishing architecture principles, engineering standards, and platform frameworks that are adopted company-wide and set the standard for mobile development at scale
Lead the design of next-generation mobile frameworks and foundational systems that serve tens of thousands of field technicians daily, with an uncompromising focus on platform longevity, extensibility, and resilience
Partner at the executive and VP level across product, design, data, and backend to shape long-range roadmaps and ensure iOS capabilities are a strategic driver of business outcomes
Serve as the definitive technical authority for iOS across the entire organization—establishing alignment across multiple engineering orgs, resolving the most complex cross-functional ambiguities, and owning the highest-stakes architectural decisions
Identify and drive strategic technical investments: evaluate emerging Apple frameworks, platform capabilities, and industry trends to ensure ServiceTitan maintains a durable competitive advantage on mobile
Architect elegant, scalable integrations with backend services via GraphQL, establishing patterns for data access and API design that scale with the platform
Champion and evolve ServiceTitan’s use of The Composable Architecture (TCA)—driving shared state management, performance optimization, and modular design patterns across the iOS engineering community
Define the AI-assisted development strategy for iOS engineering—establishing how tools like Claude, GitHub Copilot, Cursor, and Windsurf are integrated into engineering workflows to compound developer productivity at scale
Grow and inspire the next generation of staff and senior engineers—serving as a technical role model, thought partner, and mentor across the iOS org and beyond
Set and hold the engineering bar: code quality, performance standards, testing philosophy, and architectural integrity. Your influence shapes what ‘great’ looks like for all of iOS engineering
