Join Our Android Platform Team as a Mobile Principal Engineer – Shape the Future of the Marriott Bonvoy App!

Are you ready to make a real impact with your code? Define and build the next evolution of mobile solutions that elevate the Marriott experience. You’ll oversee various mini-projects, ensuring they’re delivered on time and within scope —while leveraging the latest technologies in innovative and meaningful ways.

As a key technical subject matter expert on our Android Platform Team, you’ll play a pivotal role in advancing the Marriott Bonvoy app, providing strategic technical advisory, helping define the Target Architecture for the Platform and advising on the Mobile Platform Roadmap, while driving innovation and excellence across our feature teams.

You’ll collaborate with top-tier talent—including other Principal Engineers, Engineering Directors, Solution Architects, Feature Team Tech Leads, Product Leads, UX Designers, QA Engineers and more — to deliver high-impact solutions that matter. You’ll be the go-to expert for tackling the toughest problems and delivering high-quality, scalable solutions. Your work will directly support our strategic goals, blending hands-on development with technical advisory responsibilities, leading architecture and framework initiatives.

In this role, you’ll partner with Product Owners and lead technical workgroups, acting as a go-to expert for complex, non-routine challenges. You’ll dive into research, design, and implementation of cutting-edge capabilities that meet both current and future developer and user needs while ensuring alignment with our highest standards in design, technology and security.

You’ll lead by example—conducting code reviews, mentoring developers, and recommending improvements to workflows, tools, and standards that elevate the entire mobile engineering discipline.

As a thought leader, you’ll stay on the cutting edge of the mobile ecosystem, exploring OS and device capabilities, researching emerging tools and libraries, and assessing new technologies through hands-on proofs of concept. You’ll also play a key role in educating and inspiring the broader mobile engineering community—both inside and outside the organization.

If you're passionate about crafting elegant code, solving real-world problems, and working in a dynamic, collaborative environment, we’d love to meet you.
