DESCRIPTION

Staff Software Engineer, Mobile (Android, Kotlin, Full Stack) Availability & Commitment Confirmation Form (40 hrs/week, Remote) All application steps are reused whenever another role requires the same step, so you never have to upload your resume or take the same interview twice Join a product engineering team building native mobile and full-stack experiences used by customers every day. We're partnering with a large enterprise technology organization to place a Staff Software Engineer on the team behind its Android and iOS apps. It's a mobile-first role, but engineers here also pitch in on backend services, APIs, and web, and use AI coding tools as a normal part of their day. If you enjoy owning features end to end and learning new parts of the stack, this is a great fit. This is a full-time commitment of 40 hours per week. This is a W-2 employment position with Cincinnatus LLC, with the opportunity to be placed within a leading enterprise client's engineering organization as part of their extended workforce. Key Responsibilities Build and ship features for the team's native mobile apps, mainly Android in Kotlin. Contribute beyond mobile when needed, across backend services, APIs, and web applications. Use AI-powered developer tools to get up to speed on unfamiliar code and ship with quality. Take part in technical design, code reviews, and production support. Work closely with Product, UX, and partner engineering teams, and help other engineers grow. 3. Core
