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.
What You'll Do
- 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.
You're a Good Fit If You
- 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.
