Healthcare systems are struggling; our solution is communication.

We have a bold vision: everyone involved in a patient’s care - including the patient - should be able to communicate easily with each other. And we believe every NHS staff member should be using our software to make that happen. We want to make healthcare genuinely better.
We are solving one of the biggest challenges of our generation, and to do this, we need the best talent possible to help us raise the bar… this is where you come in.

Our products are used by over 98% of GP practices and half of NHS hospitals, impacting millions of lives. As a Senior Data Engineer, your role will be mission-critical. You will be central to shaping the core communication infrastructure of the NHS. You’ll directly enable faster, safer, and more accessible patient care by ensuring that the vast flow of communication data is structured, reliable, and ready to power life-saving insights and real-time decision-making.

The Unique Challenges You'll Solve

This isn't just about executing tasks or managing projects. You'll be:

• Architecting for the NHS Scale: Designing and scaling a robust data architecture that handles massive event-driven communication flows across nearly every GP practice in the UK.

• Bridging the Gap Between Engineering and Insight: Collaborating deeply with product and data teams to transform raw healthcare communication data into high-performance models for analytics and Machine Learning.

• Building Resilient ELT Ecosystems: Implementing sophisticated ELT practices in a cloud environment where data integrity and security are paramount for patient safety.
  

What We're Looking For:

We’re looking for a Senior Data Scientist with strong data engineering foundations — someone who enjoys getting hands-on with pipelines as much as building models.

• End-to-End Pipeline Builder
  Proven experience designing and implementing ingestion and ETL/ELT pipelines from scratch using Python and SQL in production environments.

• Strong Data Modelling & Warehousing Expertise
  Deep understanding of modern cloud data platforms (e.g. Snowflake, BigQuery, Redshift) and data transformation tools like DBT, with a focus on creating clean, reliable, and reusable datasets.

• AI & ML Curiosity
  Experience (or strong interest) in building and operationalising machine learning models, with an eye toward how strong data foundations enable better AI outcomes.

• Architectural Ownership
  Comfortable making and owning decisions around data architecture to support analytics, experimentation, and ML at scale.

• Product & Impact Mindset
  You think beyond pipelines — you care about how data drives real-world outcomes, especially in a healthcare context.

• Highly Collaborative
  Able to work cross-functionally with product, engineering, and data teams to shape problems and deliver solutions.

• Comfortable with Ambiguity
  Excited by greenfield challenges, undefined problems, and the opportunity to build something meaningful from the ground up.

Our Principles in Action

• Fix healthcare communication: Healthcare systems are struggling; our solution is communication - all of our efforts are centred here.

• Be relentlessly resourceful: We embrace constraints as they force us to think differently, be creative, and focus.

• Embrace challenge: We value constructive conflict over harmony, having tough conversations for the best outcome.
