Build the in-house mobile engineering capability behind Fieldpiece’s connected products.

You’ll work closely with external teams while establishing stronger internal technical ownership. You’ll define the mobile architecture and technical strategy while remaining hands-on—developing critical components, solving complex engineering problems, and setting the technical foundation for our future internal mobile team. Our mobile applications sit at the center of a connected ecosystem spanning mobile, Bluetooth/BLE-enabled tools and sensors, cloud services, APIs, data platforms, and SaaS/DaaS capabilities.
Fieldpiece is a privately held, global leader in professional HVACR tools and test instruments.

- Strong knowledge of mobile architecture, security, performance, data synchronization, testing, mobile CI/CD, automated testing, observability, and release management.
- Strong communication skills and the ability to influence technical decisions across teams – internally and externally.
Even Better If You Have

- Using AI-assisted or agentic development tools to improve engineering productivity.
