高级/资深产品工程师，移动端
Senior / Staff Product Engineer, Mobile
**关于Radar**
[Radar](https://radar.com) 是全球领先的地理位置服务提供商，提供地理围栏SDK、地图API和用于营销、欺诈检测和运营团队的AI解决方案。
为什么Radar是最佳工作场所？
- 我们被一些世界上最优秀的公司所信赖，从高增长的初创公司到财富500强企业。
- 我们拥有惊人的规模：每天处理来自数亿设备的超过10亿次API调用。
- 我们资源充足，并已从世界级投资机构（包括Accel和Insight Partners）筹集了8550万美元。
- 我们有高性能文化，每个职位都有雄心勃勃且具有创业精神的同事。
- 我们最近搬进了位于曼哈顿熨斗区的令人惊叹的新办公室。
- 我们最近被Crain's评为纽约市十大最佳工作场所之一。
尽管我们取得了增长和规模上的进步，但我们才刚刚开始。这就是你的机会。
**关于该职位**
我们正在寻找产品工程师，在多个移动开发栈上构建功能。在过去一年中，我们的SDK在全球安装量已超过1亿台设备，我们的稳定流量为每秒10,000次请求。我们的SDK是开源的（[**Android**](https://github.com/radarlabs/radar-sdk-android)，[**iOS**](https://github.com/radarlabs/radar-sdk-ios))，抽象了位置服务之间的跨平台差异，使你只需几行代码即可在应用中添加地理围栏、位置跟踪和地图功能。你还将参与我们的演示应用，包括“Waypoint”，一款内部及客户用于测试Radar SDK的应用。
**我们如何工作：**
我们大部分工程团队成员曾是技术联合创始人或来自Waterloo和CMU等学校的Radar实习生。Radar的大多数工程师符合两种类型之一：要么是在某一技术栈上有资深水平，要么是“多栈”工程师，无论级别如何。我们称其为“多栈”，因为“全栈”通常意味着“前端和后端”，但Radar工程师也可能涉及移动开发或数据工程。当然，你不需要在所有这些方面都是专家，但渴望学习、在不同技术栈之间切换并完成任务才是关键。
我们非常重视快速交付和与客户的沟通。我们致力于实现全栈位置基础设施的产品愿景，但也知道客户反馈是通往黄金的宝藏地图。虽然Slack是我们公司的大脑，但在我们的纽约总部亲自协作是让我们高效完成工作的最快方式。我们每周见面

**About Radar**
[Radar](https://radar.com) is the global leader in geolocation, with geofencing SDKs, maps APIs, and AI-enabled solutions for marketing, fraud, and operations teams.
Why is Radar the best place to work?
- We're trusted by some of the world's best companies, from high-growth startups to the Fortune 500.
- We have incredible scale: We're processing over 1 billion API calls per day from hundreds of millions of devices.
- We're well-resourced, and we've raised $85.5M from world-class investors, including Accel and Insight Partners.
- We have a high-performance culture, with ambitious and entrepreneurial teammates in every role.
- We recently moved into an amazing new office in Flatiron, Manhattan, NYC.
- We were recently named a top 10 best place to work in NYC by Crain's.
Despite our growth and scale, we're still just getting started. That's where you come in.
**About the role**
We'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**](https://github.com/radarlabs/radar-sdk-android), [**iOS**](https://github.com/radarlabs/radar-sdk-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.
We sponsor OpenStreetMaps, MapLibre, and OpenAddresses.
**How we use AI:**
- Engineers choose what AI tools they use, Claude and Codex 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 Codex also review all PRs.
- There is a range of how much engineers use AI. Most use it daily if not weekly.
- We are excited about what AI can do, but we also recognize the risks and don't compromise our coding standards.
**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 mobile infrastructure built with Kotlin, Objective-C, Swift, as well as wrapper SDKs written in React Native, Flutter and Capacitor. ( [**Android SDK**](https://github.com/radarlabs/radar-sdk-android), [**iOS SDK**](https://github.com/radarlabs/radar-sdk-ios))
