Senior Data Engineer

Who are we? 

Arenko was founded in 2014 and we are growing rapidly in an emerging sector. We’d describe ourselves as fast-paced and inclusive. Our team are self-motivated problem solvers who take a collaborative approach to help the business develop and grow.

So what do we do?

As we move to the high-renewables and low carbon era, electricity storage is transforming the way the energy industry operates. The energy industry is fast becoming a digital and multidisciplinary sector that provides a fundamental service for modern society, but these needs must be delivered in a socially responsible way. Arenko is using new technology to add flexibility to the grid and secure supply in this fast-changing industry, offering a huge variety of opportunities for the future. At Arenko we are strongly committed to our mission of building a sustainable future by enabling a zero-carbon grid worldwide. Energy storage has a crucial role to play in the energy transition, and our technology enables the transformation of energy systems. We have committed a Sustainability Strategy more details of which can be found on our website at https://arenko.group/sustainability/

What’s the role? 

At Arenko, we’re at the forefront of the energy transition, and data is our driving force. As a Senior Data Engineer, you will be pivotal in designing, building, and managing the infrastructure that enables efficient processing and analysis of our large and diverse datasets, ranging from power market data to asset telemetry. You will play a key role in driving data-driven decisions across Arenko and transforming the electricity grid in the UK and beyond.

Our Primary tech stack & toolchain includes:

• Python: data services

• S3/ Athena: data lake

• Prefect: ETL pipelines

• Pulsar:  messaging and event streaming

• Cassandra and Postgres: databases

• AWS and Terraform: infrastructure

• GitLab: version control and CI/CD

As part of the Data team, you will work in an agile, cross-functional team, collaborating closely with your teammates and stakeholders across the business. Like all high-performing teams, you will have a high degree of autonomy to solve interesting problems that will make a real impact on the energy transition.

You will:

• Engage in cross-team collaboration: Work closely with data scientists, software engineers, stakeholders, etc. to deliver solutions that optimise energy storage assets.

• Lead data engineering initiatives: Take charge of planning, designing, and developing data engineering projects.

• ETL process design and implementation: Create efficient Extract, Transform, Load (ETL) processes to streamline data integration and transformation.

• Data modelling: Design, document, and maintain data models within the data lake. Transform raw incoming data into models that clearly represent the real world.

• Encourage best practices: Define and promote best practices for data pipeline development and tooling. Mentor the wider data team on effective ways of working.

• DevOps adoption: Embrace a DevOps culture by implementing Terraform and infrastructure as code (IaC) for our AWS data estate.

• Ensure data quality and consistency: Maintain high standards of data integrity across multiple data sources.

• Mentorship and team guidance: Foster a collaborative and innovative team culture by mentoring and guiding fellow team members.

• You have a degree in computer science or a related discipline, or are able to demonstrate equivalent workplace experience.

• You have extensive experience in leading projects focused on data collection, storage systems and data pipelines.

• You have advanced Python programming skills.

• You have an in-depth understanding of ETL technologies and best practices.

• You can demonstrate your ability to integrate with external APIs for both data collection and providing data feeds to customers and third parties.

• You have hands-on experience with data storage, processing and analytics in cloud platforms  (e.g., AWS, Google Cloud, Azure).

• You’re familiar with SQL and NoSQL databases and big data frameworks like Spark, Pulsar, etc.

• You’re an organised and adaptable team player capable of leading and mentoring colleagues.

• You’re skilled at communicating with stakeholders to identify needs and evaluate alternative technical solutions and strategies.

So what’s in it for you? 

Hopefully the first thing is you love what we do and want to be part of the mission but let’s be honest…that’s probably not why you’re getting up to work everyday.

We know that rewarding our employees is the best way to make them feel valued. This is a journey we’d love you to take with us and as we grow we look forward to finding more ways to reward and thank you for your commitment to our mission. We currently offer the following benefits with more to come in future; 

• 25 days holidays in addition to public holidays, carry over flex and festive office closure (a pretty decent annual leave allowance even if we do say so ourselves!)

• A genuine approach to flexible working - the vast majority of our employees spend at least a day or 2 each week in the office but we’re open to making this work for everyone, their personal circumstances and their workloads

• Enhanced parental leave offerings with 6 months of full salary for the primary caregiver and 1 month for the secondary caregiver

• A yearly salary review for all employees

• We are proud to support the continuous professional growth of our employees by providing a personal annual learning and development budget and fully covering the costs of professional membership fees and subscriptions relevant to your role

• Access to LinkedIn Learning on us

• Bike to Work Scheme (because it wouldn’t be very on brand if we didn’t encourage you to think about how your travel affects the environment)

• Octopus EV Scheme (see above!)

• A commitment to your wellbeing, with access to our Employee Assistance Programme and complimentary eye tests in partnership with Specsavers

• Internal working groups to focus on the things that matter to you like our “Women of Arenko”. “Diversity, Equity and Inclusion” and “Parents of Arenko” groups

• As part of our DEI efforts, we are currently in partnership with MotherBoard which enable us to be committed to improving the working lives of mums and females at Arenko
