Senior / Staff Site Reliability Engineer

About the role

We're looking for Site Reliability Engineers to work on our production infrastructure. Radar is a high-throughput, data intensive application handling 1 billion+ API calls per day. Over the past year, Radar has been used from over 100M devices worldwide. We run a multi-availability zone architecture and a major initiative is to enhance our deployment to be multi-region.

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 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 Copilot review all PRs.
• There is a range of how much engineers use AI.
• 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.
• 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 to 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 Hiring Process

• After a call with our Technical Recruiter, you'll do several technical Zoom calls with members of our engineering team: 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.

What You’ll Do

• Work on core Radar infrastructure using Terraform all deployed to AWS via EKS.
• Work on critical company-level initiatives, for example, 99.99+% availability, multi-region deployment, and cloud cost-saving activities.
• Your work will be used by 100's of millions of devices.
• Be part of the on-call rotation (one week rotation every 1-2 months).
