We believe that climate adaptation is a necessity, not a luxury, and communities deserve access to powerful software that helps them plan for the future. The challenge of climate change is complex – it implicates how municipalities plan, manage capital, and communicate to both residents and higher levels of government. Forerunner helps local communities do these things better by empowering them to access, understand, and mobilize local-level flood risk data at scale.
The RoleWe’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.
What You’ll DoBuild and scale mobile applications using React Native, delivering high-quality, performant experiences across iOS and Android
Own features end-to-end, from early design and architecture through production and iteration
Develop intuitive, responsive mobile interfaces that work seamlessly in real-world field conditions (low connectivity, high urgency)
Collaborate closely with product, design, and backend teams to ship impactful features
Integrate and optimize APIs, geospatial data, and real-time workflows within mobile applications
Identify and solve performance bottlenecks to ensure native-like speed and reliability
Contribute to mobile architecture decisions, including when to leverage native modules (iOS/Android) for performance or platform-specific needs
Improve developer experience through tooling, testing, and best practices
Mentor engineers and help raise the bar for mobile engineering across the team
5+ years of software engineering experience, with a strong focus on mobile development
3+ years building production applications with React Native
Deep proficiency in JavaScript/TypeScript and React
Experience building and maintaining cross-platform mobile applications (iOS + Android)
Strong understanding of mobile performance, UI/UX, and responsiveness
Experience integrating RESTful APIs and handling complex data flows
Familiarity with native mobile development (Swift/Kotlin or Objective-C/Java) and when to use it
Strong product sense and ability to operate in ambiguous, fast-moving environments
Excellent communication and collaboration skills
Experience with offline-first or field-based mobile applications
Background in geospatial data, mapping, or GIS systems
Experience with state management (Redux, Context API) and modern mobile architecture patterns
Familiarity with CI/CD pipelines for mobile apps and app store deployments
Experience working in GovTech, climate tech, or other regulated/complex domains

What We Do
Forerunner is a Series B company building the AI-powered intelligence layer for local government — helping large cities and counties finally make sense of the data they already have. Here's the problem we're solving: cities spend millions on permit systems, GIS, and asset management tools, but still can't answer their most important operational questions. Data sits fragmented across systems that don't talk to each other. Valuable observations from field crews never get captured. And none of today's tools help agencies connect the dots and take action. Forerunner sits on top of the tech stack agencies already have. We connect their existing systems, give frontline teams an AI-guided mobile experience to fill the gaps, and turn fragmented information into decisions and actions that reduce liability, surface revenue, and prevent issues from becoming emergencies. We serve nearly 200 governments across the country — and we're growing fast.
Why Work With Us
If you want to work on hard infrastructure problems that affect every community in America, with a team that's already trusted by the agencies on the front lines of it, we'd love to meet you.
