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 $85.5 million 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 a Data Platform Engineer to build out the next generation of our data platform. The ideal candidate has been a data platform engineer on a large system and is energized by deeply understanding customer pain points and opportunities related to our data platform. To date this has been a shared responsibility on our engineering team, but as we've grown to over 1 billion API calls per day (with lots of data exhaust into our data lake), we're hiring a Data Platform Engineering team to modernize and level up our data stack. This role can be either in our NYC HQ or remote in the US. How we work Most of our engineering team are former technical co‑founders or former Radar interns from schools like Waterloo and CMU. Engineers may specialize in one stack or be “Multi‑Stack” at any level. We value a desire to learn, jump around to different stacks, and get things done. Shipping fast and talking to customers is a priority. We meet on Mondays to plan the week in small groups and use Linear for planning. Engineers lead projects, work closely with customers, prospects, and sales teams to deliver value. The stack Our data stack includes Kinesis, S3, Athena, Terraform, Airflow, Parquet, Metabase, Python, Redis, MongoDB, and Kubernetes. Primary languages are TypeScript, Rust, and Python. Most engineers are on the on‑call rotation. We sponsor OpenStreetMaps, MapLibre, and OpenAddresses. How we use AI Engineers choose the AI tools they use; Claude and Codex are most popular. We are actively building Claude skills – for example we have taught it to debug our geospatial database, HorizonDB. All code changes are reviewed by an engineer knowledgeable in that area, and AI tools also review PRs. AI usage varies; many engineers use it daily or weekly. We embrace AI’s potential while upholding our coding standards. The hiring process After a call with our Technical Recruiter, you will have technical Zoom calls with our engineering team: code screen, coding round, and system design round. If those go well, we invite you to our NYC HQ for a final round interview where you meet co‑founders, others from outside engineering, and learn more about our culture. We discuss whether the match is right. What you’ll do Build core Radar data infrastructure using Kinesis, S3, Athena, Terraform, Airflow, Parquet, Metabase, Python, Redis, and Mongo.
