The Role

We are implementing a full-scale data warehouse using Snowflake and Kafka. To ensure long-term success, we’re hiring a dedicated Data Engineer to own and maintain this system.

As our first dedicated Data Engineer, you will help shape how data is structured, accessed, and used at Duel. You'll work across multiple functions, ensuring that data is not only available but also meaningful and usable to those who need it, whether that’s engineers, product managers, or customer success teams.

We’re growing fast, but determined to retain the culture and agility of a small engineering team. That means being part of discussions, sharing knowledge openly, and embracing an iterative, action-oriented mindset. We are looking for someone who thrives in a fast-moving, high-impact environment, where they can drive change and own how data is leveraged across the company.

This role is about more than just technical capability. The right person will be a problem solver, a strong communicator, and an active contributor to a growing, high-impact team

We’re Looking for Someone Who Will…

• Take full ownership of the data warehouse infrastructure, including Snowflake and Kafka, once the initial architecture is in place.

• Maintain, optimise, and extend our platform to integrate new data sources and support evolving business needs.

• Ensure performance, security, and cost efficiency as data volume grows.

• Work with engineering teams to ensure data is modeled correctly for business intelligence and AI-readiness.

• Support the future integration of AI by ensuring that data is clean and structured for machine learning and model development in later phases.

• Act as the bridge between engineering, data science, and customer success.

• Work with product managers to ensure they have access to the right data for decision-making.

• Support the company's self-serve data model, ensuring teams can efficiently access the data they need without unnecessary dependencies.

• Ensure data pipelines comply with UK and US data laws, including GDPR and the California Consumer Privacy Act (CCPA).

• Implement governance best practices to ensure data accuracy, lineage, and controlled access.

We’d love to hear from you if you..

• Have 4+ years of experience in a data engineering role, preferably in SaaS, MarTech, or a data-driven environment.

• Have the ability to break down complex problems, investigate effectively, and drive solutions.

• You enjoy working in cross-functional teams, including engineering, product, and customer success.

• You thrive in an autonomous environment, taking ownership, spotting issues and making decisions independently while keeping teams aligned and informed.

• You work iteratively, preferring to ship quickly, get feedback, and refine solutions rather than over-planning in isolation.

• Value creating systems and processes that allow other teams to move faster and be more self-sufficient.

• Shares work openly, documenting decisions and keeping key stakeholders informed.

• Comfortable navigating uncertainty and helping shape solutions without needing a rigid roadmap.
