Healf – Senior Data Platform Lead (Full‑time, Mid‑Senior level) – London, England, United Kingdom. Salary up to £140k.


Do your life’s best work – If modern wellbeing were redesigned from scratch, it wouldn’t live in a GP’s office or a cluttered supplement aisle. It would be digital‑first, beautifully curated, and powered by data that actually helps you feel your best.


We’re building an e‑commerce platform at the intersection of personalised health and curated wellbeing. Healf connects customers with the world’s most effective products across EAT, MOVE, MIND and SLEEP. With a culture‑shaping storytelling and cutting‑edge health tech, we’re redefining how the world shops and lives well.


About Us

  • Founded by two brothers whose own wellbeing journeys inspired the mission to empower others.
  • Grounded in The Healf Standard – five principles that define how we work and win:
  • We Work Harder Than Anyone Else: Building something that improves lives takes long hours, grit, and sacrifice, but we thrive on it.

  • Obsession Over Talent: Talent alone isn’t enough – relentless curiosity and a drive to grow set us apart.
  • The Healf Lifestyle: We live what we preach – personal commitment to wellbeing fuels our productivity.
  • Stronger Together: Everyone owns their lane, but we run as a unit.

The Role

We’re seeking an experienced and strategic Lead Data Engineer to guide our data platform and infrastructure, accelerating the growth of our health and wellbeing e‑commerce platform. In this senior position, you’ll architect and oversee a scalable, high‑quality data ecosystem, champion best practices across our modern data stack (Snowflake, dbt, ThoughtSpot, AWS), and mentor a growing team of data and analytics engineers.


Where You’ll Make An Impact
Data Platform Leadership & Strategy

  • Define the technical roadmap for our core data platform, setting standards for data architecture, infrastructure scalability, and CI/CD.
  • Ensure governance, security, and compliance across our entire data ecosystem (Snowflake, dbt, AWS).

Data Engineering & Architecture

  • Architect and optimise our ETL/ELT pipelines, leveraging AWS services (S3, Glue, Lambda, Step Functions) for scalable data ingestion and orchestration.
  • Build robust frameworks for data ingestion, transformation, and serving layers with a focus on performance and cost efficiency.

Technical Mentorship & Development

  • Provide technical guidance to a growing team of data analysts and analytics engineers, conducting design reviews, and fostering a strong engineering culture.
  • Mentor engineers on technical best practices and help them advance their engineering skills.

Collaboration & Business Enablement

  • Partner with analytics, product, and marketing teams to translate business needs into scalable data solutions.
  • Evolve our BI layer (e.g., ThoughtSpot) to enable trustworthy, self‑service analytics for business users.

Data Reliability & Innovation

  • Implement robust monitoring, alerting, and data validation frameworks to ensure the reliability of our data pipelines and datasets.
  • Stay current with emerging data technologies (lakehouse, streaming) and continuously modernise our data stack.

What You’ll Bring

  • 4+ years of experience in a data engineering role, ideally in e‑commerce or D2C environments.
  • Proven expertise in Snowflake and dbt for large‑scale data architecture, modeling, and transformation.
  • Strong proficiency in SQL (query tuning, optimisation, execution plans).
  • Proficiency in Python for scripting, automation, and integration.
  • Hands‑on experience with AWS data services: S3, Glue, Lambda/Step Functions.
  • Experience implementing data observability and reliability frameworks.
  • Demonstrated leadership in growing engineering teams, conducting architecture reviews, and driving coding standards.
  • Excellent ability to collaborate with business stakeholders and communicate technical trade‑offs clearly.
  • Familiarity with BI platforms (ThoughtSpot, Looker, Tableau) and enabling scalable self‑service analytics.
  • A strategic thinker passionate about data infrastructure, best practices, and enabling a data‑driven culture.

Why Join Healf?

  • Do your life’s best work – Build something that matters, with a team that moves fast and aims high.
  • Surround yourself with A+ talent – You’ll work with high‑performers who care deeply and raise the standard every day.
  • Be a builder – This isn’t a cog‑in‑the‑machine role. You’ll help shape our voice, culture, and growth.
  • Wellbeing is the lifestyle – From office yoga to Healf Zone insights, everything we do is rooted in our pillars: EAT, MOVE, MIND, SLEEP.
