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.

Over the past year, the Radar SDK has been installed on over 100M devices worldwide and our steady state traffic is 10,000 qps.

About the role

We're looking for a Backend Engineer to work on our geocoding and routing infrastructure. HorizonDB, our next-gen proprietary geospatial database, powers geocoding and text search workloads all from a single process Rust binary. HorizonDB can process 2000 requests per second per core with a p50 latency of 1ms.

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 the hardest and most valuable practices we have is Walk A Mile - which is shorthand for putting yourself in the user's shoes - but also for literally walking a mile and dogfooding the Radar SDK, because you can't create location infrastructure behind a desk - you have see how the device behaves in the real world. To us, a week is a long time, and we expect to ship big things every week.

The stack:

The HorizonDB kernel is RocksDB, FSTs and Tantivy.

Our data pipelines are written in Airflow and Scala Spark.

We use Terraform to manage our infrastructure.

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.

What you’ll do:

  • Work on core Radar search, geocoding, and routing infrastructure using Rust, RocksDB, Tantivy, S3/Athena, Redis, Airflow, EMR, Scala, and Terraform all deployed to AWS
  • Have your work be used by 100's of millions of devices
  • Talk to Radar customers and prospects, hear their feedback, incorporate it into your work and make them successful

You should:

  • Have experience building search infrastructure
  • Be interested in talking to customers or prospects and making them successful
  • Be deeply curious about how things work, and have the tenacity to sit with hard problems and power through them

Bonus points if you:

  • Are a former technical co-founder
  • Have experience with geocoding, routing, or mapping

You’ll work with
