About Recoy

Recoy is a fast-paced start-up aiming to accelerate the energy transition by providing smart solutions to integrate cheap, but highly variable solar and wind energy production into a stable energy system.

We develop smart charging software that allows flexible assets such as electrical buses, e-trucks, megawatt-scale electric boilers and large-scale batteries to be controlled in a smart way by reacting to fluctuations in the electricity prices and/or predictions of the production of solar and wind energy. This enables energy-intensive companies to save costs by using electricity when prices are low or even negative and by making better use of and expanding the existing energy flexibility. As a result, we help to keep the electricity grid in balance, reduce congestion on the electricity grid and support the successful integration of sustainable energy sources such as solar and wind energy.

We are currently operating and further developing our ‘Real-Time Optimization Platform’, a cloud-based solution that will be key in accomplishing our goals. It combines the variation in energy prices and production with the customers’ flexibility in energy storage and consumption. By using forecasting models and optimization techniques we can exercise optimal real-time control of flexible energy assets in combination with on-site solar panels and wind turbines.

Recoy recently formed a strategic partnership with Heliox, market leader in fast charging systems within public transport, e-trucks, marine, mining and port equipment with a strong-focus on vehicle-to-grid technology. The partnerships gives Recoy access to a strong portfolio of DC charging infrastructure and stationary storage that we can optimise to unlock value for our customers and accelerate the energy transition.

Our Culture

Recoy is a fast-growing company with an informal culture where we solve tangible problems. We like to think out-of-the box and move fast and agile. We are a tight-knit team and believe collaboration is key to deliver the best result for our customers. You will be working in a small but quickly growing development team (full stack), working closely together with business development. This means that you will quickly learn about all aspects of Recoy, the energy domain and of course our customers, making the job interesting and diverse. We regularly pair up and aim to standardize how we work. That makes it much easier to work together and help each other when needed. We value a good work-life balance, so we regularly work from home. Of course, we enjoy and value meeting each other regularly in our comfortable office in Amsterdam to meet-up, collaborate and share a good walk, lunch, or drinks.

About the job

We are looking for a (junior) .NET engineer who can help to develop and scale our cloud-based optimization platform using modern cloud concepts that will allow scaling in a cost-effective way. We try to keep things lean and simple, and leverage on the capabilities of the cloud such as serverless functions and database as a service. We are looking to expand across our entire technology stack (front and back-end), so based on your experience and preference you can choose your own focus.

In this role you will have a major influence on the further development of our platform, and you can really make an impact to speed up the energy transition in the Netherlands and the rest of Europe.

The core tools and technologies that we currently use are:

  • .Net Core
  • AWS suite: Lambda, EventBridge, RDS (SQL Server)
  • Git (Trunk Based Development)

We offer you a full-time job (0.8 to 1.0 FTE), working partly from home, and partly from our office. You would become part of a start-up adventure, and work with highly motivated, energetic, and experienced colleagues.

About You

You are a curious-minded individual, eager to learn and share ideas. You have excellent analytical skills and take pride in developing high quality code. You value success of the team over personal success and are comfortable adopting a shared way of working. You have a passion for the energy transition and the motivation to make a difference. Your background would ideally cover:

  • A Bachelors or Master’s degree in Mathematics, Physics, Computer Science, or a related field
  • Proven proficiency in .NET development (0-3 years of working experience)
  • Familiarity with test-driven development and agile development practices
  • Excellent communication skills in English, native Dutch speaking is a plus
  • Experience with event-driven cloud architecture is a plus
  • Experience working with AWS suite is a plus
  • Experience with front-end development is a plus
