About the role

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.

Scope of Work

• 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.

What you’ll bring

• 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.
• Ability to engage reliably for at least 40 hours/week during weekdays.
• Clear communication and a collaborative, curious mindset.
• Nice to have: exposure to LLM-powered features (RAG, embeddings, agents), experience with accessibility standards, or work on apps with accounts, payments, or orders. You don't need all of these to apply.
• About Cincinnatus LLC: Cincinnatus LLC is an enterprise staffing company that partners with leading technology companies to source and employ highly skilled professionals for contingent and contract-based opportunities. Cincinnatus serves as the employer of record for these engagements, providing W-2 employment, payroll, benefits, and compliance, while placing employees directly within client teams to work on high-impact initiatives.
