It ingests and stores your analytics, errors, replays, and business data so you and your agents can query and act on it.\nWe launched out of Y Combinator's W20 cohort. We've since shipped more than a dozen products, including:\nA suite of analytics and observability tools, including product analytics, replay vision, AI observability, and error tracking\n\nPostHog MCP for users and their agents to query and act on their product and business data\n\nData warehouse so users can query product and customer data together using custom SQL insights.\n\nWe are:\nProduct-led. More than 500K organizations have installed PostHog, mostly driven by word-of-mouth. We have intensely strong product-market fit.\n\nDefault alive. 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.\n\nWell-funded. We've raised more than $180m from some of the world's top investors. We're set up for a long, ambitious journey.\n\nWe're focused on building an awesome product for end users, hiring exceptional teammates, shipping fast, and being as weird as possible.\nThings we care about\nTransparency: 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. Internally, we share revenue, notes and slides from board meetings, and fundraising plans, so everyone has the context they need to make good decisions.\n\nAutonomy: 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 and make product decisions. Teams are flexible and easy to change when needed.\n\nShipping fast: 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 who can outship much larger companies because they own their products end-to-end.\n\nTime 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, and we prioritize heads down building time over perfect coordination. This will be the most productive job you've ever had.\n\nBeing 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 with dubious shareholder value. Doing weird stuff is a competitive advantage. And it's fun.\n\nWhat you'll be doing\nClickHouse is the core piece of infrastructure at PostHog. Every product and customer relies on it to ingest, store, and query data.\nWe 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.\nThis 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.\nYou'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.\nYou'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.\nWe're also building a query optimizer for ClickHouse, which means you will work on query performance tooling.\nYou’ll fit right in if:\nYou 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.\n\nYou bring experience in automating Dynamic provisioning instances. Strong experience with utilizing Terraform, Ansible and K8s is important.\n\nYou 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.\n\nYou bring the Stack we need. We build using Python, Terraform, Ansible, Kubernetes, AWS, and Zookeeper (An alternative to Zookeeper is fine)\n\nYou’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.\n\nIf this sounds like you, we should talk.\nWe are committed to ensuring a fair and accessible interview process. If you need any accommodations or adjustments, please let us know.","description_format":"text","description_chars":5084,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"United States","iso":"US","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Product Analytics & Session Replay","A/B Testing & Experimentation"],"lifecycle":[{"event":"open","at":"2026-09-08T03:10:05Z"},{"event":"close","at":"2026-10-15T22:19:21Z"},{"event":"reopen","at":"2026-10-26T14:26:29Z"},{"event":"close","at":"2026-11-02T15:37:57Z"}],"visa":[],"liveness":null,"pay":null,"html_url":"https://alion.io/job/posthog-clickhouse-operations-engineer","json_url":"https://alion.io/job/posthog-clickhouse-operations-engineer.json","meta":{"generated_at":"2026-11-03T06:36:49Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":9156,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-04T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":33807},"rest":"https://alion.io/mcp/rest/get_company?id=33807"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fposthog-clickhouse-operations-engineer"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fposthog-clickhouse-operations-engineer"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fposthog-clickhouse-operations-engineer"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/posthog-clickhouse-operations-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fposthog-clickhouse-operations-engineer"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":522848}},{"tool":"search_jobs","arguments":{"company":"posthog.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":522848},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
