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.
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.
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.
Interest in AI: You are genuinely curious about AI and its applications. You use AI in your daily work and you are interested in applications related to the data field.
Mindset: Pragmatic, curious, and proactive. You value clean architecture, documentation, and continuous improvement.
Collaboration: Able to clearly communicate with both technical and non-technical stakeholders.
Languages: Fluent in English, both written and spoken.

Joko operates a mobile shopping app that gives users cashback, coupons, and discounts from a wide range of retailers. It earns commissions through affiliate marketing when users make purchases via the app. The app is free for users and automatically calculates the carbon footprint of each transaction, encouraging more conscious consumption. How it works: users browse partners in the app, activate deals, and make purchases through affiliate links to get rewards; the platform tracks sales and credits cashback automatically to the user’s account. How it is different: it combines traditional cashback and coupon offers with real-time carbon footprint insights for each purchase, offering environmental visibility alongside savings, within a broad consumer market. What the company aims for: to help people save money on everyday spending while promoting greener consumption and to grow its affiliate network across retailers.
