Senior Software Engineer, Mobile; React Native

Stronger, more resilient communities are built by the people inside government and regulated industries who keep critical infrastructure running. But they're working against real headwinds: fragmented data, field crews without the right tools, and high-stakes decisions made without a complete picture.

Forerunner exists to fix that. We build intelligent software that connects the systems these agencies and firms already rely on, fills the gaps those systems can't, and turns fragmented information into decisions and actions that reduce liability, surface revenue, and prevent small problems from becoming emergencies.

We're hiring a Senior Software Engineer, Mobile to lead the evolution of our mobile experience. You'll play a key role in building and scaling our React Native application
, which is critical to how governments collect, act on, and communicate real-world data in the field.

This is a high-impact role at the intersection of geospatial data, field operations, and climate resilience
- where performance, reliability, and usability directly affect outcomes for communities.
