We’re seeking a Senior Data Engineer to lead and grow our internal R&D data team. This is a hands-on leadership role for someone who enjoys shaping technical solutions, building team capability, and engaging with stakeholders across the business.

Please note, the working pattern for this role will be hybrid, with two days onsite at the Bristol office.

You’ll work with two data engineers who are already delivering tools and insights using Budibase (for low-code workflow applications), PostgreSQL, and Power BI. These tools support business process automation and data-driven decision-making.

There is a major opportunity to modernise how we deliver and manage data as well as expanding the use of data and analytics inside the business. The right candidate will find real scope to influence direction and develop business cases for change, implement good practice, and guide the team toward scalable, robust solutions.

This role suits someone with strong technical grounding, experience in data transformation or modernisation, and the soft skills to consult, influence, and mentor.

Key Responsibilities

  • Lead technical delivery of data workflows, reports, and tools used to support internal business processes.
  • Mentor and coach junior data engineers, helping them grow their technical and consulting skills.
  • Collaborate with stakeholders across the business to understand needs and deliver value-driven data solutions.
  • Drive modernization efforts, identifying opportunities to improve scalability, maintainability, and performance.
  • Champion best practices in data engineering, governance, and low-code/no-code tooling.
  • Translate business requirements into robust data architectures and analytical workflows.
  • Maintain and improve integrations between Budibase applications, PostgreSQL databases, and Power BI dashboards.

What We’re Looking For

  • Proven experience in senior or lead data engineering roles, ideally within internal consultancy or transformation environments.
  • Strong experience with PostgreSQL, Power BI, and low-code platforms (Budibase or similar).
  • Solid programming skills, preferably in Python, especially for ETL development and support.
  • Proficiency with version control systems (e.g., GitHub), with an understanding of best practices for collaboration, review, and deployment.
  • Familiarity with REST APIs, including how to design, consume, and integrate them into data workflows.
  • Track record of working closely with non-technical stakeholders to deliver effective data solutions.
  • Experience with data transformation, process optimization, or modernizing legacy tooling.
  • Strong communication and influencing skills—comfortable challenging assumptions and guiding decision-making.
  • Passion for mentoring and developing junior talent.
  • A pragmatic, problem-solving mindset—able to work effectively with limited resources.
