高级/资深产品工程师，后端
Senior / Staff Product Engineer, Backend
Radar 是全球领先的地理定位公司，提供地理围栏 SDK、地图 API 和用于营销、欺诈和运营团队的 AI 驱动解决方案。
为什么 Radar 是最好的工作场所？
- 我们被世界上一些最好的公司所信赖，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：每天处理超过 10 亿次 API 调用，来自数亿台设备。
- 我们资源充足，已从世界级投资者 Accel 和 Insight Partners 获得 8550 万美元融资。
- 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。
- 我们最近搬进了曼哈顿熨斗区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，但我们才刚刚开始。这就是你的机会。
**关于该职位：**
我们正在寻找后端产品工程师来扩展核心 Radar 平台。我们的日常流量是每天 10 亿次 API 调用（每秒 15,000 次请求），因此你将处于大规模环境中。该职位可在我们的纽约总部或美国远程办公。
**我们的工作方式：**
我们大部分工程团队成员都是前技术联合创始人或来自 Waterloo 和 CMU 等学校的 Radar 实习生。Radar 的大多数工程师可以归类为两种类型之一：在某一技术栈上达到资深水平，或者在任何级别上具备“多技术栈”能力。“多技术栈”是因为“全栈”通常意味着“前端和后端”，但 Radar 工程师可能还会涉及移动端或数据工程。当然，你不需要在所有这些方面都成为专家，但对学习、切换不同技术栈以及完成任务的渴望才是关键。
我们非常重视快速交付和与客户沟通。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宝藏的路线图。虽然 Slack 是我们公司的大脑，但在纽约总部面对面协作是我们完成工作的最快方式。我们每周一开会，以小组形式规划本周的工作，并使用 Linear 进行计划。
对我们来说，一周是很长的时间，我们期望每周都能交付重要的成果。
**技术栈：**
API 层是一个 Node.js TypeScript 应用程序。
我们的主要后端服务是一个用 Rust 编写的地理空间数据库，我们称之为 [HorizonDB](https://radar.com/blog/high-performance-geocoding-in-rust)。

[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 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 at scale. This role can either be in our NYC HQ or remote in the US.
**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.
To us, a week is a long time, and we expect to ship big things every week.
**The stack:**
The API layer is a Node.js TypeScript app.
Our main backend service is a geospatial database written in Rust that we call [HorizonDB](https://radar.com/blog/high-performance-geocoding-in-rust).
We use MongoDB, 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 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 products using TypeScript, Rust, Python and Scala
- Work on features across the backend API layer and offline pipelines
- Have your work power 1 Billion API calls / day
- Talk to Radar customers and prospects, hear their feedback, incorporate it into your work and make them successful
**You should:**
- Think of yourself as a generalist engineer first, not tied to any particular stack
- Are interested in talking to customers or prospects and making them successful
- Are 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 worked on a high throughput, high growth SaaS application
- Have worked on geospatial infrastructure
