About Us

Radar is location infrastructure for every product and service. Companies like Vercel, Panera, and T-Mobile use Radar's geofencing SDKs and maps APIs to power location-based experiences across hundreds of millions of devices worldwide.

Founded in 2016, Radar is headquartered in New York, NY. Radar has raised $85.5M from leading venture capital firms including Accel and Insight Partners.

About the role

We're looking for a Product Engineer to build multi-stack features across backend, frontend, and mobile. Over the past year, our SDKs have been installed on over 100M devices worldwide and our steady state traffic is 10,000 qps. Our SDKs are open-source (Android, iOS), abstracting away cross-platform differences between location services and allowing you to add geofencing, location tracking, and maps to your apps with just a few lines of code. You'll also work on our demo apps, including "Waypoint," an app used internally and by customers to test the Radar SDK.

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.

We care a lot about shipping fast and talking to customers. We're committed to our product vision of full-stack location infrastructure, but we also know that customer feedback is a treasure map to gold. Even though Slack is the brain of our company, working together in-person in our NYC HQ is the fastest way for us to get things done. We meet on Mondays to plan out work for the week in small groups and use Linear for planning. All projects are run by an Engineering lead, an executive and a Go-to-Market lead. Engineers figure out what to build, talk to customers, talk to prospects, help close them, get them live and make them successful.

One of our most important company values is "Walk a mile," as in walking a mile in the customer's shoes, but also as in literally walking a mile, getting up from your desk and developing a deep understanding of how location services behave in the real world. To us, a week is a long time, and we expect to ship big things every week.

The stack:

Our mobile stack includes Kotlin, Objective-C, and Swift. We also have thin cross-platform SDK wrappers for React Native, Capacitor, Flutter, and few others.

The frontend is React and Next.js deployed to Vercel.

The server is a Node.js Express app and a Rust backend Geocoder. We use MongoDB, S3/Athena, Redis, Airflow and everything is deployed to AWS.

Most engineers are in the on-call rotation.

We sponsor OpenStreetMaps, MapLibre, and OpenAddresses.

The hiring process:

After a brief call with our CTO, we'll invite you to our NYC HQ for an interview if we think there is a possible match. During that time we'll work on system design problems together and do some coding for 2 hours to build something simple. You might meet one of our co-founders and we'll also go into more depth about how we work to see if there is a match.
