Product Engineer, Backend

About the role

We're looking for Backend Product Engineers to extend the core Radar platform. Our daily traffic is 1 Billion API calls / day (15,000 requests / second) so you will be operating s role can either be in our NYC HQ or remote in the US.

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 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 API layer is a Node.js Type Script app.

Our main backend service is a geospatial database written in Rust that we call Horizon

DB.

We use Mongo

DB, S3/Athena, Redis, and Airflow.

Everything is deployed to AWS via Kubernetes on EKS using Terraform.

Most engineers are in the on‑call rotation.

We sponsor Open Street Maps , Map Libre, and Open Addresses.

After a call with our CTO, we'll do several technical Zoom calls: code screen, coding round, and system design round. If those go well we'll invite you to our NYC HQ for a final round interview. You'll meet one of our co‑founders, someone from outside engineering, and meet more people from Radar. We'll go into more depth about how we work to see if there is a match.
