Staff Software Engineer, Mobile (Android, Kotlin, Full Stack)

Join a product engineering team building native mobile and full-stack experiences used by customers every day.

1. Overview

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.

2. 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 Qualifications

• 4+ years of professional software engineering experience.
• Hands-on native mobile experience, ideally Android with Kotlin and Jetpack. iOS/Swift is welcome too, and Flutter or React Native experience counts if you've also done some native work.
• Some production experience outside mobile, such as backend services, APIs, or web apps.
• Solid engineering fundamentals: design, testing, and debugging.
• Comfortable using AI coding tools such as Copilot, Cursor, or Claude.
