Job description

Hi! We're Forerunner.

Hi! We're Forerunner.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.

The Role

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.

What You’ll Do

• Build 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

What We’re Looking For

• 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

Nice to Have

• 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 offer

• We're mission-driven. Our mission orients our business strategy and pushes us to work with a sense of urgency. We’re in the weeds - our entire team spends time engaging with our partners in the field to better understand the real-world problems they face.
• We're a small team. As a member of our growing team, you will quickly become an invaluable part of our organization and have a meaningful impact on our business and technical direction. We welcome unique perspectives and backgrounds. Your opinion matters and we hope you'll share it.
• We build each other up. A team works best when its members are adequately equipped with the tools to tackle the problems they are facing. Forerunner strives to provide adequate feedback and appropriate learning opportunities to help all its team members expand their skills.
• We value in-person collaboration. Some of our best work happens when we're solving problems together in the same room, so this role is hybrid and based near one of our offices: New York City, San Francisco, or Portland, Maine.
• We want you to be happy and healthy. Forerunner offers competitive compensation, health/vision/dental coverage, a 401k plan, and one expensed lunch per week. We also have a quarterly wellness reimbursement so that you can have flexibility in defining what “health” means to you.

The salary range for this position is $185,000-$215,000. This posting may span more than one career level. Compensation is determined based on a variety of factors, including an individual’s skills, experience, and qualifications.

Forerunner is an equal opportunity employer committed to embracing diversity and the perspectives of individuals from all backgrounds.
