- This software platform allows us to offer responsive, reliable services to Electricity grid operators (National Grid in the UK) while also analysing trading markets to optimise the storage and release of energy (and ultimately the revenue) of assets under our control
- Working within an agile environment, you will be a critical part of a dynamic, passionate and talented software team from across disciplines creating a flexible and efficient platform that our users will use to transform the makeup of modern national electricity grids
- Our primary tech stack & tool chain is:
- Golang for backend services
- Cassandra, TimescaleDB databases and s3\Athena lake
- Backend microservice architecture with Pulsar, RESTFul and Websocket APIs
- AWS for infrastructure
- GitLab for version control and code management, and CI/CD
- As part of the Software team, you’ll be in an agile cross-functional team, working closely with your teammates including the Product Manager and Scrum Master to collaborate with stakeholders from across the business. As with all high performing teams, you’ll work with a high degree of autonomy to solve interesting problems that will make a real impact in the world of renewable energy usage
- We have a genuine need to operate both personally and technically with real agility to retain our leading position and as thought leaders, as the markets we operate in and the problems we need to solve, are quickly evolving
- Technical Leadership: Provide technical leadership within the team, overseeing the construction, maintenance, and evolution of critical components in our cutting-edge platform

Application process
- Initial Call (30 minutes) is an informal chat with one of our Engineering Leaders. It’s an opportunity for us to understand your motivations for joining Arenko, share more about who we are and ensure that we are a good fit for each other. We’ll ask about how you like to work and discuss a project you’re most proud of, so please come prepared to talk about it
- Take-Home Technical Test (~2 hours). We believe in assessing real-world problem-solving, not memorised coding challenges. We’ll provide a take-home test that reflects the kind of problems we solve and will show us your approach to coding and problem-solving. The test will be energy-related and designed to take just a couple of hours
- Technical Interview (1 hour) builds on your take-home test. We’ll discuss your code; why you made certain decisions, what alternatives you considered and your overall approach. Be prepared to share your code on screen and talk us through it. This is also your chance to meet your future colleagues, and we encourage you to use this opportunity to ask lots of questions about the role, team and company culture
- Final Round (1 hour). Here, you’ll meet your future line manager for a behavioural and leadership interview. We’ll discuss real-world situations you’ve encountered and how you approached them. Using the STAR (Situation, Task, Action, Result) technique can help structure your responses. Leadership is a quality we value in everyone, so we’d love to hear about moments when you’ve stepped up or inspired others
- Decision. True to our startup mentality, we aim to provide feedback quickly. If we’re a match, we’ll make you an offer and hope that you’ll join us! No matter the outcome, we'll always make an effort to provide constructive feedback because it’s the right thing to do

Our take
In 2020, renewable energy was the only energy source for which demand increased and it is expected that renewables will account for 90% of capacity increases over the next two years. Arenko Group aims to modernise the infrastructure that ensures this capacity can be optimised.
The company provides software solutions that allow energy operators to increase their grids' flexibility and secure their energy supply more efficiently. Through their AI-powered software system, Arenko supports battery asset owners and operators to optimise their energy storage by allowing them to automatically buy and sell electricity on the grid ensuring they maximise revenue across multiple power and energy markets at the same time.
Arenko currently works with the battery and grid operators across the UK and are part of the National Grid ESO’s Technology Advisory Council, along with the likes of Transport for London and Octopus Energy. With a focus on creating a faster path to net zero and a more resilient energy grid, Arenko aims to become a global leader in this space.
