关于 POSTHOG
产品开发过去意味着手动编写代码、运行分析、诊断错误，并使用数十种工具推出更改。
PostHog 让产品实现自动驾驶 https://posthog.com/self-driving。它是唯一一个能像副驾驶一样与你（和你的 AI 代理）一起完成所有工作的平台——自主完成。
我们从开源产品分析开始，从 Y Combinator 的 W20 届毕业 https://posthog.com/handbook/story。此后我们推出了十多个产品 https://posthog.com/products，包括：
- PostHog Desktop https://posthog.com/desktop，唯一一个能理解你的产品而非仅代码库的 AI 开发工具。
- 内置的数据仓库 https://posthog.com/docs/data-warehouse，让用户可以使用自定义 SQL 洞察同时查询产品和客户数据。
- PostHog AI https://posthog.com/ai，一个由 AI 驱动的分析师，可以回答产品问题，帮助用户找到有用会话记录，并编写自定义 SQL 查询。
我们是：
1. 以产品为导向。超过 45 万个组织安装了 PostHog，主要由口碑驱动。我们有非常强的产品市场契合度。
2. 默认活跃 https://paulgraham.com/aord.html。收入增长非常迅速，我们效率很高。我们融资是为了推动雄心和更快增长，而不是维持运营。
3. 获得充足资金。我们从世界顶级投资者那里筹集了超过 1.8 亿美元。我们为一段漫长而雄心勃勃的旅程做好了准备。
我们专注于为终端用户打造出色的产品，招聘优秀的团队成员，快速交付，并尽可能地保持独特 https://posthog.com/deskhog。
我们关注的事情
- 透明：任何人都可以在我们的公开公司手册 https://posthog.com/handbook 中了解我们的路线图、如何支付（甚至解雇）员工、我们的战略以及我们如何工作。内部，我们分享收入、董事会会议的笔记和幻灯片以及融资计划，以便每个人都能获得做出良好决策所需的信息。
- 自主：我们不会告诉任何人该做什么。每个人根据对客户影响最大的事情，以及他们觉得有趣和有动力去做的事情来选择接下来要做的工作。工程师领导产品团队 https://posthog.com/handbook/wide-company 并做出产品决策 https://posthog.com/handbook/which-products。当需要时，团队灵活且易于改变。

ABOUT POSTHOG
Product development used to mean manually writing code, running analysis, diagnosing bugs, and rolling out changes using dozens of tools.
PostHog makes products self-driving https://posthog.com/self-driving. It's the only platform that acts like a co-pilot for you (and your AI agents) to do it all – autonomously.
We started with open-source product analytics, launched out of Y Combinator's W20 cohort https://posthog.com/handbook/story. We've since shipped more than a dozen products https://posthog.com/products, including:
- PostHog Desktop https://posthog.com/desktop, the only AI devtool that understands your product, not just your codebase.
- A built-in data warehouse https://posthog.com/docs/data-warehouse, so users can query product and customer data together using custom SQL insights.
- PostHog AI https://posthog.com/ai, an AI-powered analyst that answers product questions, helps users find useful session recordings, and writes custom SQL queries.
We are:
1. Product-led. More than 450,000 organizations have installed PostHog, mostly driven by word-of-mouth. We have intensely strong product-market fit.
2. Default alive https://paulgraham.com/aord.html. Revenue is growing incredibly quickly, and we're very efficient. We raise money to push ambition and grow faster, not to keep the lights on.
3. Well-funded. We've raised more than $180m from some of the world's top investors. We're set up for a long, ambitious journey.
We're focused on building an awesome product for end users, hiring exceptional teammates, shipping fast, and being as weird as possible https://posthog.com/deskhog.
THINGS WE CARE ABOUT
- Transparency: Everyone can read about our roadmap, how we pay (or even let go of) people, our strategy, and how we work, in our public company handbook https://posthog.com/handbook. Internally, we share revenue, notes and slides from board meetings, and fundraising plans, so everyone has the context they need to make good decisions.
- Autonomy: We don’t tell anyone what to do. Everyone chooses what to work on next based on what's going to have the biggest impact on our customers, and what they find interesting and motivating to work on. Engineers lead product teams https://posthog.com/handbook/wide-company and make product decisions https://posthog.com/handbook/which-products. Teams are flexible and easy to change when needed.
- Shipping fast: Why not now? https://posthog.com/handbook/values#why-not-now We want to build a lot of products; we can't do that shipping at a normal pace. We've built the company around small teams – autonomous, highly-efficient groups of cracked engineers https://posthog.com/founders/cracked-manifesto who can outship much larger companies because they own their products end-to-end.
- Time for building: Nothing gets shipped in a meeting. We're a natively remote company. We default to async communication – PRs > Issues > Slack. Tuesdays and Thursdays are meeting-free days https://posthog.com/handbook/company/culture#were-on-the-makers-schedule, and we prioritize heads down building time over perfect coordination. This will be the most productive job you've ever had.
- Ambition: We want to solve big problems. We strongly believe that aiming for the best possible upside, and sometimes missing, is better than never trying. We're optimistic about what's possible and our ability to get there.
- Being weird: Weird means redesigning an already world-class website for the 5th time. It means shipping literally every product that relates to customer data. It means building an objectively unnecessary developer toy https://posthog.com/deskhog with dubious shareholder value. Doing weird stuff is a competitive advantage. And it's fun.
WHAT YOU'LL BE DOING
ClickHouse is the core piece of infrastructure at PostHog https://posthog.com/docs/how-posthog-works/clickhouse. Every product and customer relies on it to ingest, store, and query data.
We need someone to automate, manage, and maintain ClickHouse as we grow towards capturing trillions of events per year and having one of the world’s largest clusters.
This includes ClickHouse operations and scaling infrastructure, as well as node and instance-level performance optimization. We want to ensure that we have the right hardware deployed at the right time for each workload on ClickHouse.
You'll build systems and automations for the provisioning and scaling of our large ClickHouse clusters, handling over 100 PB's of data. You'll have the ability to investigate and experiment using the latest hardware that cloud providers have to offer in order to find the optimal setup for our solution. And yes, You'll have a budget to do this.
You'll be using Terraform, Ansible, and Kubernetes to automate the dynamic provisioning of instances and work on a bleeding edge ClickHouse implementation, like open format backed tables, and not just maintenance.
We're also building a query optimizer for ClickHouse, which means you will work on query performance tooling.
YOU’LL FIT RIGHT IN IF:
- You bring OLAP Database Experience. This role is focussed on ClickHouse, but if you bring strong experience with other OLAP Databases, that's great. We're looking for people that went into the internals of ClickHouse and other OLAP Databases, not high level users.
- You bring experience in automating Dynamic provisioning instances. Strong experience with utilizing Terraform, Ansible and K8s is important.
- You bring experience with Scale and Complexity! We're building and operating high-scale complex data storage solutions, we need you to have experience with the challenges this brings.
- You bring the Stack we need. We build using Python, Terraform, Ansible, Kubernetes, AWS, and Zookeeper (An alternative to Zookeeper is fine)
- You’re ready to do the best work of your career. We have incredible distribution, a big financial cushion and an amazing team. There’s probably no better place to see how far you can go.
If this sounds like you, we should talk.
We are committed to ensuring a fair and accessible interview process. If you need any accommodations or adjustments, please let us know.
