Principal Architect, Product Engineering at Niantic Spatial · LumiJobs

Responsibilities

The Principal Architect is the technical steward for the Product Engineering organization. This role will be responsible for ensuring that every product, platform, API, SDK, and service fits together into a cohesive, scalable ecosystem. This is one of the most senior individual contributor roles within Product Engineering. Reporting to the Senior Director of Product Engineering, you will serve as a technical partner in defining the long-term architecture of Niantic Spatial's product platform while remaining actively engaged in the implementation and evolution of the technology.
This is a hands-on engineering role - not a traditional enterprise architecture function. You will participate in architecture reviews, prototype complex solutions, contribute production code where it matters most, and mentor senior engineers. You will work closely with Product Management, Research, Engineering, and Design to ensure technical decisions advance the company's product vision while maintaining architectural consistency across the platform. Success here requires understanding not only how systems should be built, but why.
Organizational Scope
The Principal Architect provides technical leadership across the entire Product Engineering organization, including the Product Foundations Team, SDK, Mobile Engineering, Web Engineering, and Delivery. The role partners closely with Research to guide the transition of new technologies into scalable, production-ready products.
Technical Strategy
Define and evolve the long-term technical architecture for the Product Engineering ecosystem.
Ensure products, services, SDKs, and applications share consistent architectural patterns and engineering principles.
Balance short-term product delivery with long-term platform health and maintainability.
Drive architectural decisions that improve scalability, reliability, security, developer experience, and operational simplicity.
Product Partnership
Partner closely with Product Management to understand product strategy and ensure technical investments support long-term customer value.
Collaborate with Research to evaluate emerging technologies and define clear paths to productization.
