Working at Limejump

Limejump is an award-winning energy tech company, connecting customers to our in-house trading and data centres as we work to revolutionise the UK energy industry.

We are an ambitious company, looking to change the way businesses and consumers interact with their electricity. Following our acquisition by Shell New Energies in 2019, we are looking for talented individuals to support exponential growth against our sustainable goals. This is an exciting opportunity to join an independently operating, fully owned subsidiary of a globally established energy company and to become instrumental in challenging and changing the smart grid space. Our culture is shaped by individuals who want to make a difference every day and enjoy working in a collaborative environment.


The Role 

We want you as our new Senior Data Engineer to be apart and help Limejump shape a more sustainable world of cleaner energy. You will be responsible for contributing to and helping lead the architecture, design and roll-out of a new enterprise-wide data platform.

Your primary responsibility is to oversee the development of our new data warehouse, built on top of Snowflake. You will oversee architecture and design, as well as hands on building out of infrastructure and pipelines; likely leveraging Confluent Cloud/Kafka. You will also take on a wider role supporting data strategy too, whilst being supported from people across the business including data scientists, platform engineers and a BI analyst.

You will have a proven track record of implementing modern data architectures, a strong attention to detail and the ability to learn and work independently. You will report directly into our Head of Data Science.

  • Building pipelines to ingest data, both batch and in real-time.
  • Educating team members in data engineering best practices.

  • Maintain strong relationships with internal and external stakeholders.
  • Project and team management.

Essential Skills & Experience:

  • Good verbal and written communication skills.
  • Both project delivery and management experience.
  • Experience working with both technical and non-technical stakeholders.
  • Experience with modern, cloud-based data architectures, ideally with experience of Snowflake and/or AWS data services.
  • Experience with both batch and streaming ingestion frameworks, and specific experience with Kafka.
  • A flexible, innovative mindset: this is a fast-moving often complex environment where you will have to take responsibility for solving difficult problems.
  • A degree (BSc/ MSc/ PhD) in a quantitative subject (Maths, Physical sciences, Computer science etc…) or equivalent experience.
  • Minimum of 4 years of experience using Python/SQL for data engineering work within data-intensive environments. Ideally in the energy, tech, finance, or consumer goods sector.

Desirable Technology Experience:

  • Snowflake
  • Confluent Cloud
  • Debezium
  • DBT
  • Airflow
  • Looker


Why you would love working at Limejump:

  • Flexible working options and 25 days annual leave (+ a day off for your birthday!).
  • An Innovation Card loaded with your learning budget and 10% time to learn at work.
  • Private Medical Insurance with Axa PPP. Cover has £0 excess per year for employee only. Option to also include family and/or partner via payroll deductions.
  • A subsidised onsite gym membership and a Cycle to Work scheme.
