Data Engineer

Ready to revolutionize healthcare, making it faster and more accessible than ever before?

How we started:

Back in 2013, our founder Dwayne D'Souza saw an opportunity to give people faster and more convenient access to medications using technology. We've grown rapidly since our inception, without any external funding whatsoever – achieving profitability through innovation and a highly disciplined approach to growth.

Where we are now:

We've earned the trust of millions of people worldwide through our top-selling products and well-known brands: MedExpress, Dermatica, ZipHealth, RocketRX, and Levity. A lot of our success is down to having our own pharmacies, manufacturers and products – spearheaded by leading in-house medical teams, researchers and pharmacists. Between 2023 and 2024 our global revenue tripled; £60m to £180m (300% year-on-year growth). We're looking to do the same in 2025; move into new territories, and further accelerate our growth journey. There's never been a more exciting time to join HeliosX.

Where we're going:

Over the next five years, you'll support our goal to become a world-leading healthcare partner, deepening our customer relationships, expanding into new countries, and diversifying our product portfolio to treat more conditions. You'll be part of helping more people access prescription treatments and, most importantly, making personalised care better, quicker and easier for everyone.

Come be a part of making our dream of easier and faster healthcare a reality!

About the role: The Data Engineer will be essential in the continuous development and operation of the data platform, focusing on building reliable data pipelines and ensuring data quality for both internal teams and external customer-facing products. You will execute on the data strategy and take responsibility for the implementation and maintenance of data solutions.

What you'll be doing:

• Develop and Maintain Data Pipelines: Build and maintain core data processing workflows using dbt for transformations. This includes developing scalable SQL logic, creating reusable data models, and implementing incremental processing strategies following software engineering best practices (version control, testing, modular design).
• Manage Cloud Data Platform (Snowflake): Configure and manage the Snowflake cloud data warehouse, focusing on optimizing query performance, controlling costs, and configuring compute resources. Ensure the platform scales effectively by implementing proper data clustering and partitioning strategies.
• Ensure Data Quality and Testing: Implement comprehensive dbt testing frameworks (schema, data, and custom tests) and set up automated data quality monitoring, alerting, and issue resolution processes.
• Establish Data Governance: Establish and enforce data governance policies, manage data access controls, and ensure security and privacy compliance.
• Drive Cross-Functional Data Strategy: Collaborate with Engineering teams to design robust event schemas and instrumentation for consistent data collection at the source.

What you'll bring:

• 2+ years of specific, proven experience delivering end-to-end data solutions using modern data stack tools.
• 2+ years of expert SQL experience, with a focus on real-time or near-real-time data processing.
• 1+ years of hands-on dbt experience building models, including those designed to feed customer-facing features and operational analytics.
• Proven experience building data pipelines that feed directly into application databases or APIs, and a clear understanding of low-latency data requirements.
• Experience building data products that surface in customer-facing UIs (e.g., dashboards, personalization). You understand API design and how analytics data integrates with the application layer.
• Experience leading technical initiatives or mentoring junior team members
