🧚🏻♂️ OUR DATA TEAM
The Data team at Joko is turning mountains of data into actionable insights for all the teams! We are part of the Operations
department led by our COO, and our mission is to empower the company to make informed decisions on solid, trustworthy foundations.
More specifically, the team's responsibilities are:
- State-of-the-art analytics & data stack: We build top-notch analyses, predictive models, and robust data infrastructure. We
operate a modern data stack (Snowflake, dbt, Airbyte, and Metabase) and continuously raise the bar on scalability, reliability,
and performance.
- AI-driven autonomy for stakeholders: We are doubling down on the combination of AI and data to unlock a new level of autonomy
for our stakeholders, seamlessly bridging data insights with the AI tools we use.
- Spread the data culture: At Joko, we have a strong engineering and tech culture across all teams. We work hand-in-hand with our
stakeholders, providing support and training on data tools, and building close relationships to ensure our solutions align
perfectly with their operational needs and evolve with them over time.
🎯 WHAT YOU WILL DO
As a Data Engineer, you will own and scale our data infrastructure, working closely with Data Analysts, Product Managers, and
Engineers to build a reliable, secure, and high-performing data platform. This is a high-impact role with significant autonomy as
we invest seriously in data engineering.
Your responsibilities will include:
- Scale our data infrastructure: Lead the evolution of our stack to make it more scalable, reliable, and cost-efficient.
Anticipate growth in data volume and complexity, and design systems with performance in mind.
- Power AI initiatives: Lay solid data engineering foundations that enable AI data products that are used by all stakeholders
across the company.
- Design and maintain data pipelines: Build robust processes to ingest data from multiple sources (internal systems, APIs,
external tools) and orchestrate them efficiently.
- Unlock scalable data modeling: Support Data Analysts by improving dbt project organization, factorizing jobs, and ensuring
quality and scalability of transformations across the stack.
- Ensure data quality & observability: Implement monitoring, testing, and alerting systems to ensure the freshness, reliability,
and accuracy of data across the company.
- Manage data access & governance: Define and enforce access control policies (e.g., in Snowflake, Metabase) to ensure data is
secure, well-permissioned, and compliant.
- Implement documentation & knowledge sharing: Ensure models, pipelines, and workflows are well-documented to support onboarding,
collaboration, and long-term autonomy of the team.
- Tackle exciting challenges ahead: Support new market launches, manage growing data volumes, and help centralize pipelines
within an orchestration tool.
👀 WHO WE'RE LOOKING FOR
- Experience: You have 5+ years of experience in data engineering or a similar role, with demonstrated ownership over building
and/or scaling data infrastructure.
- Track record: You have led the implementation or scaling of a modern data stack (e.g., Airflow, dbt, BigQuery/Snowflake, event
streaming, etc.) in a startup or scale-up environment.
- Technical skills: Proficient in SQL and Python. Solid hands-on experience with orchestration tools (Airflow or similar) and
cloud environments (Snowflake, GCP, AWS).
Architectural thinking: Strong understanding of data modeling, warehousing principles, and performance optimization techniques.
