The Opportunity

We are working exclusively with a fast-growing clean energy technology company that is redefining how green hydrogen is produced at industrial scale. Backed by significant funding and long-term commercial partnerships, they are now expanding their data capability to support the next phase of laboratory and pilot-plant development.

They are seeking a Data Engineer / Analytics Engineer to help build and maintain the core experimental data platform that underpins scientific development, validation, and scale-up activities.

This is a hands-on, technically engaging role operating at the intersection of data engineering, analytics, and laboratory experimentation. You will be responsible for transforming raw, real-world experimental and sensor data into structured, trusted datasets used daily by scientists and engineers.

This position is ideally suited to someone who enjoys working with messy, real-world data and wants to contribute directly to the commercialisation of next-generation clean energy technology.

Key Responsibilities

Build and maintain data pipelines for ingesting laboratory and plant data (CSV, Excel, sensor and time-series sources).

Work closely with engineering and scientific teams to understand experimental data flows, formats, and validation needs.

Clean, transform, and structure datasets for analysis, modelling, and reporting.

Support the development of metadata standards to improve experiment traceability and comparability.

Contribute to dashboards and analytical views used by R&D teams.

Monitor data quality and investigate anomalies or pipeline issues.

Improve documentation, data standards, and best practices.

Progressively take ownership of operational data workflows under the mentorship of a senior data engineer.

About You

You will ideally bring:

Strong Python skills for data processing and analysis.

Solid SQL capability and experience working with structured datasets.

Experience or interest in time-series data and sensor-driven environments.

A proactive, self-starting mindset with strong problem-solving ability.

Comfort working within a fast-moving, technically complex start-up environment.

A collaborative approach to working with scientists and engineers.

Desirable:

Exposure to cloud platforms (GCP or AWS).

Familiarity with analytics tools and dashboards.

Experience with laboratory, scientific, or industrial datasets.

Interest in hydrogen, energy systems, or electrochemistry.

Understanding of ETL pipelines and data modelling concepts.
