Location: Denver; Los Angeles
THE ROLE
We're hiring our first Regional Vice President for the Southwest. The territory runs from the Rockies (Colorado and Utah) through Arizona and the desert Southwest to Southern California. It covers some of the fastest-growing tech corridors in the country, plus a dense base of digital-native, media, gaming, and AI companies that already run on real-time data. You'll report to Mike Hayes and build the region from the first hire: set the strategy, recruit the team, and turn a widely spread, high-potential territory into one of the strongest regions in the Americas. This is a builder's seat with a clear path to grow with the business.
WHAT YOU'LL DO
- Design a multi-hub region. Build a coverage model across hubs that are very different from one another, including Los Angeles, Orange County, San Diego, Denver/Boulder, Salt Lake City/Lehi, and Phoenix. Decide where to place reps first and how to sequence growth.
- Hire the founding team. Recruit Enterprise AEs who can sell to engineering buyers as peers: technical, commercially hungry, and able to work on their own across a large geography.
- Own the number and the forecast. Carry the regional quota, run a weekly operating rhythm, and deliver a forecast your leadership can rely on, backed by MEDDPICC-style deal qualification.
- Win where real-time data is the product. Land and expand with digital-native and AI-native companies, media and entertainment, gaming, adtech, consumer internet, and fintech, where performance and cost at scale decide the deal.
- Turn adoption into enterprise agreements. Work with our product-led growth motion to find ClickHouse Cloud and open-source users ready for a committed relationship, then expand across teams and use cases (analytics, observability, and AI workloads).
- Lead from inside the deal. Coach reps through technical evaluations, POCs, procurement, and executive negotiations. Join the calls that matter.
- Orchestrate the extended team. Partner closely with Solutions Architects, Marketing, Partners/Alliances, and cloud marketplace teams to build pipeline and run cohesive account strategies.
- Build ClickHouse's brand across the region. Show up in the local developer, data, and startup communities, from Denver and Salt Lake to LA and San Diego, through events, meetups, and executive programs.
WHAT YOU BRING
- 10+ years of enterprise software sales in data infrastructure, databases, analytics, observability, or cloud, with a strong record as a quota-carrying seller.
- 5+ years leading enterprise sales teams as a first- or second-line leader, with attainment you can back up with specifics.
- Experience building or rebuilding a region from an early stage, ideally one spread across several metros, where you set coverage, hired the first reps, and grew the business.
- A strong network across the Rockies, the Southwest, and/or Southern California, both for hiring standout AEs and for reaching enterprise buyers.
- Rigorous pipeline management, deal qualification (MEDDPICC or similar), and forecast accuracy.
- Technical credibility with engineering-led buyers. You understand the modern data stack and can hold your own in architecture conversations.
- Experience with consumption-based pricing, open-source, or product-led growth models.
- The ClickHouse DNA: integrity, hunger, and accountability. You're curious, serious about the craft, and want to build rather than inherit.
NICE TO HAVE
- Experience selling to digital-native, AI-native, media/entertainment, or gaming companies.
- A background in real-time analytics, OLAP and columnar databases, observability, or AI/LLM infrastructure.
- Experience as an early leader at a high-growth data or infrastructure company through a period of fast scaling.
- Co-selling with AWS, GCP, or Azure, and transacting through cloud marketplaces.
- Experience leading a distributed team across several states and time zones.
PERKS
- Flexible work environment - ClickHouse is a globally distributed company and remote-friendly. We currently operate in over 25 countries.
- Healthcare - Employer contributions towards your healthcare.
- Equity in the company - Every new team member who joins our company receives stock options.
- Time off - Flexible time off in the US, generous entitlement in other countries.
- A USD$500 Home office setup if you’re a remote employee.
- Global Gatherings – We believe in the power of in-person connection and offer opportunities to engage with colleagues at company-wide offsites.
CULTURE - WE ALL SHAPE IT
As part of a rapidly scaling start-up, you will be instrumental in shaping our culture.

adjoe builds the technologies behind mobile apps growth and monetization. With our core product Playtime Arcade, we've become the global leader in rewarded advertising, an ad unit built on a simple premise: users earn real in-app rewards for engaging with new apps. The result is one of the most effective value exchanges in adtech, connecting advertisers and publishers with over 770 million users annually.
Investigating 770 Million User Interactions Across a 100TB Data Lake
When a platform serves 770 million users, every optimization from reward mechanics to SDK integrations needs to be grounded in data. The Rewarded Analytics team builds the internal dashboards, alerting systems, and data pipelines that monitor the user funnel, traffic engagement, and reward consistency.
SQL and Python power deep-dive investigations and automated 100 terabyte-sized data analyses queried through Trino. Using Tableau as the main visualization tool, stakeholders have access to real-time insights on the product performance. Airflow orchestrates the pipelines that keep everything up to date. This team provides the data that turns questions into answers: every A/B experiment the product team runs, every anomaly a publisher flags, and every new SDK integration. These answers guide all the business decisions.
Your Mission & Who We Are Looking For:
- Data analyst with a strong technical foundation. You have 5+ years as a Data Analyst and work fluently in both SQL and Python, writing complex queries, big data optimizations, and analysis pipelines to support product and growth initiatives.
- Master of experimentation and A/B testing. You have deep experience designing experiments, calculating sample sizes, managing variance reduction techniques, and analyzing A/B/n tests to ensure statistically sound business decisions.
- Statistically grounded. You can reason confidently about core statistical concepts—hypothesis testing, confidence intervals, p-values, power analysis, and Bayesian vs. Frequentist approaches—and apply them to real-world product decisions.
- Not a stranger to anomaly detection. You have experience working with anomaly detection algorithms and approaches like distribution analysis and cross-population comparison to monitor test guardrail metrics and identify unexpected shifts in experiment data.
- You own the systems, not just your slice. You understand the end-to-end telemetry and feature flagging systems that power experimentation. You can speak to data flows, event tracking pipelines, architecture tradeoffs, and why things were built the way they were.
- Automation-minded across the stack. You think beyond one-off test analyses and build automated experiment reporting dashboards, reusable analytical frameworks, and data visibility solutions. Experience with dbt, Airflow, or experiment platforms (e.g., Optimizely, GrowthBook) is a strong plus.
- Collaborative and business-aware. You work closely with product managers, engineers, and growth leads to translate complex statistical results into clear, actionable recommendations that drive executive decision-making.
🌎 We welcome applications from talent worldwide and provide relocation support to Hamburg, Germany for those ready to join our team.
What’s in It for You?
At adjoe, you’re not here to just close JIRA tickets, you’re helping build the infrastructure behind one of the most impactful platforms in adtech. The systems you work on will reach hundreds of millions of users and power billions of decisions every day.
- Go Big. Own projects with impact on 770M users and push adtech boundaries.
- Move Fast. Ship solutions multiple times a day, learn from results, and keep momentum.
- Be Direct. Solve problems openly and collaborate across teams.
- Thrive Together. Grow with a diverse, global team of people from over 40 different countries that learn from each other.

What you will do:
- Analyze and evaluate the performance of our machine learning models using user-level and aggregated data, identify inefficiencies and failure patterns, and turn findings into actionable recommendations for our Data Science teams.
- Investigate how our ML models perform in the real world and compare model assumptions and predictions with actual user and business behavior. Identify gaps between offline model performance and online outcomes and help the team close them.
- Define and improve metrics for measuring ML model performance and business impact, working closely with Data Scientists and Product Managers to ensure we optimize for the right outcomes.
- Design, prepare and analyze A/B tests and other experiments to measure the impact of new models, features and algorithmic changes. Assess statistical significance, experiment quality and practical business impact.
