Requirements
  • 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.
  • Experience in automating Dynamic provisioning instances. Strong experience with utilizing Terraform, Ansible and Kubernetes is important.
  • 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.
Responsibilities
  • Automate, manage, and maintain ClickHouse as we grow towards capturing trillions of events per year and having one of the world’s largest clusters.
  • Perform ClickHouse operations and scaling infrastructure, as well as node and instance-level performance optimization.
  • Ensure that we have the right hardware deployed at the right time for each workload on ClickHouse.
  • Build systems and automations for the provisioning and scaling of our large ClickHouse clusters, handling over 100 PB's of data.
  • Investigate and experiment using the latest hardware that cloud providers have to offer in order to find the optimal setup for our solution. And you will have a budget to do this.
  • You will 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.

PostHog provides a unified platform for product analytics, feature flags, and data integration to help product teams build and ship software.

PostHog is now available in Vercel's v0

PostHog is now available in Vercel's v0. Feb 12, 2026 PostHog, Inc. has released a brand new PostHog x Vercel integration. That integration made the setup intentionally boring. Flags and experiments are defined in PostHog, synced into Vercel's native Flags system, credentials are handled automatically, and your app simply consumes them via the Flags SDK. That integration focuses on how flags and experiments run in production. Now, PostHog, Inc. is extending the same product context into Vercel's v0 via MCP, so it's available while you're building. What you can do with PostHog in v0. v0 can build directly on real codebases, enabling teams to ship production-ready apps and agents rather than prototypes or toy projects. With PostHog as a partner, v0 doesn't just generate code against your repository - it can do so with an understanding of how your product actually behaves in production. It has access to experiment results, user behavior patterns, feature flag state, and error impact, which means the software you generate reflects real product data rather than assumptions about how the product should work. There's so much you can do with PostHog in v0 that PostHog, Inc. asked its Growth team what types of prompts they'd start with. Act based on experiment results. When iterating on onboarding or activation flows, existing experiments often already contain the answer to "which direction should we take." With PostHog connected, v0 can reference experiment data and use it as context when generating UI, so new designs reflect what has already been tested in production. Suggested prompt: Based on the onboarding experiment testing long vs short signup, show me the metrics and then generate a signup flow aligned with the winning variant. Insights from its Growth team: You can use this when redesigning signup or pricing pages. For example, if a shorter signup form improved completion rate but reduced activation, that tells you friction wasn't the only issue. You might keep the shorter form but strengthen the first-run experience, add clearer value framing, or tailor the flow by acquisition channel instead of treating all users the same. Turn ideas into multivariate flags. Product changes are rarely binary. v0 can help turn a concrete idea into a properly structured multivariate feature flag that matches PostHog's experiment model, making it ready to roll out and measure without additional setup. Suggested prompt: Create a multivariate feature flag in PostHog for its new 'Quick Actions' button. Variant A is yellow, variant B is green. Insights from its Growth team: Use this for things like CTA color, button placement, or dashboard layout variations. Instead of debating whether a brighter button "feels more clickable," you can ship both versions behind a multivariate flag and measure downstream impact. Not just clicks, but whether users actually complete the next meaningful action. Ask product questions and act on the answers. Understanding what users do often comes down to a few focused questions. v0 can run trends, funnels, and HogQL queries in PostHog and surface the results directly, so decisions about flows or copy are informed by actual usage rather than assumptions. Suggested prompt: Show me a funnel from page view to signup, broken down by referral source. Insights from its Growth team: You can use this when evaluating campaign traffic. If paid users convert differently from organic users, you could generate different landing page variants tailored to intent. It's also helpful before rewriting homepage copy - if most drop-offs happen before pricing is even viewed, the issue likely isn't the pricing table. Find drop-offs and close the loop. Identifying where users drop off is only useful if it leads to follow-up. With PostHog in v0, you can move directly from analysis to targeted feedback, without stitching together multiple tools. Suggested prompt: Find my worst-performing funnel, then create a survey targeting users who dropped off asking what went wrong. Insights from its Growth team: You can use this for onboarding steps with unexplained friction. If users consistently abandon at, for example, "Connect your first integration," you can automatically trigger a short survey for that segment and ask whether it's confusion, missing documentation, or lack of perceived value. That feedback can immediately shape the next iteration. Create and summarize surveys. Qualitative feedback is most useful when patterns are clear. v0 can help create surveys and then group responses by theme once data starts coming in, making it easier to move from raw feedback to concrete next steps. Suggested prompt: Create an open-text survey asking users: 'What's the one thing you'd change about its product?' and target it to users who've been active for at least 30 days. Insights from its Growth team: Try to use this after launches or major UI changes. Instead of manually reading hundreds of open-text responses, look for recurring themes like "navigation confusion" or "missing export options." That will make it easier to prioritize fixes based on frequency and impact rather than on the loudest individual comment. Once survey responses come in, use a follow-up prompt to pull survey stats and identify the most common themes. Debug anticipating user impact. Errors are easier to prioritize when they're tied to user impact. v0 can query error data from PostHog so investigation starts with which issues affect the most users, not just which ones appeared most recently. Suggested prompt: Show me the top errors affecting the most users this week, and any new errors that appeared after yesterday's deploy. Insights from its Growth team: This should be useful after releases. If a new deploy introduced an error affecting, let's say, 15% of active users in a critical flow, that takes priority over a rare edge-case bug. It will also help you connect technical issues to real user journeys - for example, whether the error blocks upgrade, onboarding, or core usage. Keep LLM costs visible. When building AI features, cost trends matter as much as functionality. v0 can surface model-level spend from PostHog so usage decisions are based on actual data rather than surprises at the end of the month. Suggested prompt: Which LLM model is costing me the most this week, and how is the spend trending? Insights from its Growth team: This comes handy when testing different models for AI-powered features. If GPT-4-level performance doesn't meaningfully improve user outcomes compared to a cheaper model, that's an immediate optimization opportunity. Product data is most useful when it shows up at the moment decisions are made. With PostHog available in v0, you can build agents, features, and experiments with real context in mind instead of assumptions. Check it out: v0.app PostHog is an all-in-one developer platform for building successful products. PostHog, Inc. provide product analytics, web analytics, session replay, error tracking, feature flags, experiments, surveys, LLM analytics, data warehouse, CDP, and an AI product assistant to help debug your code, ship features faster, and keep all your usage and customer data in one stack.

Workflows graduate to beta! Product data, meet automation

Workflows graduate to beta! Product data, meet automation. When PostHog, Inc. first introduced Workflows (in alpha), it was still a bit rough around the edges, and many of you were brave enough to test it. Since then, PostHog, Inc. has spent a lot of time fixing, refining, and adding power where it counts. So, what does that mean in practice? You can finally automate product-led actions, like sending emails, updating properties, or triggering Slack alerts, directly from your PostHog data. No syncing tools, no duct-taped integrations, no API key scavenger hunts. Everything runs on the same event data you already track. Want to send a welcome email when a user completes onboarding? You can build the email and trigger it with an event or a delay. Want to adding branching logic based on their upgrade path? You can do that too. * Send emails, from simple notifications to full drip campaigns * Trigger Slack messages or webhooks based on live product events * Add delays, conditions, and branches to control when and how actions fire * Update user properties or trigger events as part of your automation If you've used Zapier, Make, Brevo, Active Campaign or similar tools before, the idea will feel familiar, but this time, everything happens inside PostHog. It's faster, more reliable, and you don't need to send data to third-party platforms. Teams like Grantable are already seeing the benefits. Evan Rallis, who leads product & growth there, told PostHog, Inc.: "PostHog Workflows just lives on top of the event data and the amazing user data you already have. The setup was incredibly easy." Evan said it's almost twice as fast to build automations in Workflows than with other tools, in part because he doesn't need to switch to a third-party tool and wait for data to sync. Workflows are still free during beta, so now's a good time to experiment. Try building something small - maybe an onboarding reminder, a feedback request, or a Slack alert when a user hits a key milestone. You can learn more in the docs or jump straight into launching your first workflow.
