What this role is about: Are you excited to build features that make a real-world impact at massive scale, from user interfaces to the services that power them? At RapidSOS, we create technology that helps organizations operate smarter with real-time data — and, in critical moments, powers emergency response by ensuring life-saving information reaches those who need it most.
We’re seeking a Senior Software Engineer to build intuitive, visually engaging, and robust user interfaces that bridge the gap between complex technical solutions and real-world challenges.

You’ll collaborate closely with product, design, and engineering teams to evolve a platform used by leading organizations, defining how real-time information is visualized, understood, and acted upon in emergency situations. You'll also play a pivotal role in driving architectural decisions, ensuring our interfaces are scalable, high-performing, and accessible.

Translate design ideas into high-quality, user-focused interfaces that are technically feasible
Identify opportunities to assess and enhance current applications, including refactoring code and upgrading technologies used
Collaborate in an agile environment with stakeholders across Engineering, Design, GTM, and Product to develop solutions for RapidSOS products
Leverage modern AI development tools (Claude Code, Cursor or similar) to accelerate delivery and improve code quality
Actively participate in code reviews and standups, sharing knowledge, championing best practices, and contributing to the continuous improvement of team processes
Own meaningful parts of our platform, have an impact, grow with the company
What we’re looking for in our ideal candidate:
5+ years of professional frontend or full-stack engineering experience with 3+ years of developing rich, interactive, scalable frontend applications with React and TypeScript
Proficiency with ideally Python – proficiency with Go, node.js, C++/C or a similar language will be considered with willingness to learn Python
Experience with modern CSS frameworks and libraries such as Styled Components
Experience building, maintaining, and integrating RESTful APIs and delivering comprehensive end-to-end solutions in a cloud-based environment
Ideally has experience building AI-driven features or using AI tools to enhance acceleration of development, and is proactive about leveraging emerging technologies
Strong communication and interpersonal skills; is a team player with a positive attitude
Highly self-motivated; ability to adapt and learn quickly in a fast-paced environment with a strong sense of ownership
Cares deeply about the user experience and is able to quickly identify the optimal visual strategies to meet both product and design goals
Strong proficiency in coding best practices – ability to write clean, maintainable, and testable code
Demonstrated expertise in problem solving – troubleshooting issues and debugging a large codebase
Ability and willingness to collaborate in-person quarterly, or as needed
Nice-to-have experience (but not required!):
Experience integrating with WebSocket APIs for real-time data streaming
Experience working with a Map UI provider such as Google Maps or ESRI
Experience with a JavaScript testing tool (We use Jest, Playwright, and React testing library at RapidSOS but any testing library experience would be helpful!)
