That's where you come in.\nAbout the role\nWe're looking for Product Engineers to build features across multiple mobile stacks. 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.\nHow we work:\nMost 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.\nWe 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.\nOne 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.\nThe stack:\nOur mobile stack includes Kotlin, Objective-C, and Swift. We also have thin cross-platform SDK wrappers for React Native, Capacitor, Flutter, and few others.\nWe sponsor OpenStreetMaps, MapLibre, and OpenAddresses.\nHow we use AI:\nEngineers choose what AI tools they use, Claude and Codex being the most popular.\n\nWe're actively building Claude skills - for example we've taught it how to debug HorizonDB, our geospatial database.\n\nAll code changes are reviewed by an Engineer knowledgeable in that area. Claude and Codex also review all PRs.\n\nThere is a range of how much engineers use AI. Most use it daily if not weekly.\n\nWe are excited about what AI can do, but we also recognize the risks and don't compromise our coding standards.\n\nThe hiring process:\nAfter 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.\nWhat you’ll do:\nWork on core Radar mobile infrastructure built with Kotlin, Objective-C, Swift, as well as wrapper SDKs written in React Native, Flutter and Capacitor. (Android SDK, iOS SDK)\n\nEmbody our \"Walk a mile\" value by walking around to QA and debug the Radar SDK\n\nPush the limits of what is possible with location services on iOS and Android\n\nHave your work run on 100's of millions of devices\n\nTalk to Radar customers and prospects, hear their feedback, incorporate it into your work and make them successful\n\nYou should:\nHave experience building Mobile infrastructure\n\nDon't think of yourself as an \"iOS Engineer\" or \"Android Engineer\"\n\nAre interested in talking to customers or prospects and making them successful\n\nAre deeply curious about how things work, and have the tenacity to sit with hard problems and power through them\n\nBonus points if you:\nAre a former technical co-founder\n\nHave worked on an SDK\n\nHave experience with Indoor positioning\n\nHave experience with background location or network infrastructure with respect to Doze mode, Wake Locks, Background Execution Limits, App Standby Buckets, and Foreground Services\n\nHave experience with FusedLocationProvider, GeofencingClient and Beacon monitoring and ranging\n\nYou’ll work with:\nNick Patrick, Co-Founder and CEO\n\nTim Julien, CTO\n\nLiam Meier, Director of Engineering\n\nOur customers and prospects\n\nOur Customer Success, Sales Engineering, and Sales teams\n\nWhat we offer:\nCompetitive salary\n\nMeaningful stock options in a fast-growing company\n\n401(k) plan with 4% match\n\nNew HQ in Flatiron, NYC\n\nTop-notch equipment\n\nCatered lunches\n\nUnlimited PTO\n\nHealth, dental, and vision insurance with 100% coverage for employees\n\n12 weeks of paid parental leave\n\nCommuter and fitness benefits\n\nWe’ll share full details of our benefits package at the offer stage.
