WORK ENVIRONMENT:

We are primarily a remote-first company, but you may need to travel a few times per year to visit client sites or attend meetings at designated locations with your team members. Working hours align with the Eastern Time Zone, so candidates located in the Eastern or Central time zones are preferred.

POSITION SUMMARY:

Nymbus is seeking an experienced Lead Mobile Engineer to join our engineering team. In this role, you will contribute to the design, development, and maintenance of native iOS and Android mobile applications. Working collaboratively with product management and engineering, you will analyze user requirements, contribute to solution design, implement features, integrate with back-end systems, and assist with testing.

We use Xcode and Android Studio side-by-side with Kiro (kiro.dev) as our standard AI-powered IDE, leveraging the latest Claude models from Anthropic to support design, development, and testing. In this role, engineers are expected to take an AI-first approach to their work and have experience crafting effective prompts, iterating with AI on design and specifications, managing context files, integrating with MCP servers, and reviewing AI-generated code and selected libraries.

This role includes ownership of the iOS and Android build and release lifecycle, ensuring reliable, secure, and repeatable pipelines across environments. Responsibilities include managing mobile signing and distribution requirements, such as provisioning profiles, certificates, and keystores, and supporting CI/CD and automated testing workflows using tools like Bitrise, TeamCity, and BrowserStack. As part of the role you will lead a team of four engineers split between Android and iOS. You will direct their day to day work, coach and mentor them, and work to build up their abilities to develop using an AI-first approach.

If you are a skilled Mobile Engineer with a passion for delivering high-quality mobile applications, embracing AI-powered development, leading and developing a team of talented engineers, we invite you to join our team.
