Engineering Manager, Site Reliability

About Radar Radar is the global leader in geolocation, with geofencing SDKs, maps APIs, and AI-enabled solutions for marketing, fraud, and operations teams. Why is Radar the best place to work? We're trusted by some of the world's best companies, from high-growth startups to the Fortune 500. We have incredible scale: We're processing over 1 billion API calls per day from hundreds of millions of devices. We're well-resourced, and we've raised $85.5M from world-class investors, including Accel and Insight Partners. We have a high-performance culture, with ambitious and entrepreneurial teammates in every role. We recently moved into an amazing new office in Flatiron, Manhattan, NYC. We were recently named a top 10 best place to work in NYC by Crain's. Despite our growth and scale, we're still just getting started. That's where you come in. About the role We're looking for an Engineering Manager to lead a distributed SRE team to work on our production infrastructure. You will be responsible for supporting a team and driving a roadmap that makes Radar’s services scalable and highly available worldwide. Radar is a high-throughput, data intensive application handling 1 billion+ API calls per day. Over the past year, Radar has been used on over 300MM devices worldwide. We run a multi-availability zone architecture and a major initiative is to enhance our deployment to be multi-region. The stack: We use Terraform to manage our infrastructure. We deploy everything to AWS via EKS. We use MongoDB deployed to Atlas. We do CI and deployments via CircleCI. We monitor production with CloudWatch, Grafana, Pingdom and PagerDuty. DNS is managed by CloudFlare. Most engineers are in the on-call rotation. Our main server languages are TypeScript and Rust. Our data pipelines are written in Airflow and Scala Spark. We sponsor OpenStreetMaps, MapLibre and OpenAddresses. How we use AI: Engineers choose what AI tools they use, Claude and Codex being the most popular. We're actively building Claude skills - for example we've taught it how to debug HorizonDB, our geospatial database. All code changes are reviewed by an Engineer knowledgeable in that area. Claude and Codex also review all PR s. There is a range of how much engineers use AI. Most use it daily if not weekly. We are excited about what AI can do, but we also recognize the risks and don't compromise our coding standards. How we work: Most of our engineering team are former technical co-founders or former Radar interns from schools like Waterloo and CMU. Most engineers at Radar fit one of two molds, technically: either Staff level expertise in one stack, or Multi-Stack at any level. We say Multi-Stack because "Full-Stack" has the connotation of "Frontend and Backend", but Radar Engineers might also work on Mobile or Data engineering. Not that you need to be an expert in all of those, but a desire to learn, jump around to different stacks and get things done is the important part.
