## Job description

### ABOUT THE ROLE

Join an early analytics function at an AI/ML startup and own its data foundation across the warehouse, production pipelines, BI, and conversion tracking. Your work will shape business decisions and the data used to optimize advertising performance.

### WHAT YOU'LL DO

- Design and operate the ClickHouse warehouse, including schemas, ingestion, backfills, and performance improvements.

- Build reliable Python pipelines from databases, payment systems, collaboration tools, and advertising platforms, with testing, monitoring, recovery, and data verification.

- Manage conversion tracking and attribution data, including server-side events and feeds of lifetime gross profit to advertising platforms.

- Build and maintain BI dashboards for growth, finance, support, and product, and retire outdated dashboards.

- Analyze retention, unit economics, attribution, churn, and pricing impact, and proactively flag important metric changes.

- Partner with company leaders to scope and prioritize work, using coding agents while remaining accountable for correctness and production behavior.

### WHAT WE'RE LOOKING FOR

- 2 to 10+ years of experience, including ownership of production data pipelines built with Python.

- Hands-on experience with a columnar warehouse such as ClickHouse, Snowflake, BigQuery, or Redshift.

- Experience building BI dashboards with Hex, Metabase, or Looker, and defining business metrics such as retention cohorts and unit economics.

- Familiarity with Stripe and SaaS metrics such as MRR, ARR, NDR, and LTV; experience with conversion tracking, attribution, Meta Conversions API, or Google Ads conversion imports is valuable.

- Daily use of coding agents, strong engineering ownership, and comfort working proactively in a fast-moving team.

### COMPENSATION & BENEFITS

Visa sponsorship is not available.

### LOCATION

On-site in Munich, Germany, or Warsaw, Poland.

**Live in Clera’s hiring system.** Read from the company's own applicant tracking system, not reposted from a job board — so it's a real, open requisition rather than an ad that outlived the role.

We remove it as soon as it disappears at source.
