Sr. Mobile Developer - React Native (Direct Hire)


52 Limited is a digital staffing agency with an industry-leading focus on the creative + technology space. We exclusively place tech and creative talent in direct-hire, contract-to-hire, and contract roles with our clients in Portland, Seattle, and San Francisco.

About the Role

Join our tight-knit quickly growing team to help us design, develop, and bring our core product to market. This is an exciting opportunity for someone looking to get in on the ground floor of a fast-paced pre-launch startup.

As Senior Mobile Software Engineer, you will be responsible for architecture, development, and maintenance of the React Native based mobile apps that interface with our health kit, it’s various sensors, and our cloud services.

The ideal candidate is an experienced, hands-on senior engineer who can jump in and work closely with our VP of Engineering (head of mobile apps) to take over development of our prototype apps and bring them to launch. Initially this role will report to the VP of Engineering. As we continue to scale the team there may be opportunities to move into a leadership role depending on interests and skillset.

Technical Qualifications

Bachelor’s or master’s degree in Computer Science, Electrical Engineering, or related discipline, or comparable industry experience.

Deep knowledge of hooks/state management in React

Proficient with animation of React components and complementary libraries and tools

Experience interfacing with Bluetooth (BLE + classic) devices is desirable

Soft Skills

Ownership mentality with passion to always be learning

Experience in a startup is highly desirable as we are constantly changing, adapting and focusing on minimum viable product vs. long drawn out development cycles you would normally see in an enterprise. If change or ambiguity scares you, this probably isn’t the right role for you.

If you don’t check every box above, we’d still encourage you to apply.
