Husband, dad, entrepreneur, Ruby dev, 8-bit hacker, teenage tech dreamer, game creator, space aficionado, and electric vehicle enthusiast. Relentlessly optimistic about the opportunities of science and technology.
I lived in a house built around 1605 in the Netherlands, with some of the windows being hundreds of years old, based on expert opinion. The glass had started to droop downward in certain places, almost like the resin you see in trees. It made me realize that glass is not as rigid as I thought.
Return (https://return.energy) is hiring a developer who will build the software that powers our BESS optimization algorithms. Return’s main activity is building and operating industrial-size Battery Energy Storage Systems. Our operations are located in the Netherlands, Germany, Belgium, and Spain. You will be making a measurable (country-level) impact on the transition to renewable energy. Return recently raised €300M to support its growth.
While we employ over 130 people, our teams are deliberately small. You will join the Optimizer Quant team, which builds the algorithms that decide when and how our batteries charge and discharge. Our platform automates processes in energy storage, monitoring, market optimization, sales, project management, procurement, and construction.
We expect you to be strong in Python and comfortable with APIs and backend fundamentals, cloud, Docker, and basic DevOps. You should be able to reason about system design and architecture, and to build and operate reliable data pipelines. A working understanding of optimization, time-series and forecasting, and the statistics behind quant work will help you move fast and ask the right questions. You do not need a finance background, but you should enjoy working closely with the quants who design our algorithms.
Our tech stack/toolset is straightforward: Python, PostgreSQL, TigerData, dbt, Dagster, Grafana, Terraform, self-hosted + cloud compute. We tend to keep meetings to a minimum in order to provide at least five hours of uninterrupted coding time per day. We practice code reviews and apply automated and manual testing. Our platforms are often deployed multiple times per day.
The team includes people who have co-founded several companies and/or have experience with remote development teams since 2008. They will personally help you through most of the recruiting process (there is no recruiter involved).
Return (https://return.energy) is hiring a DevOps engineer who will build and run the infrastructure behind platforms that accelerate the transition to carbon-free energy. Return's main activity is building and operating industrial-size Battery Energy Storage Systems. Our operations are located in the Netherlands, Germany, Belgium, and Spain. You will be making a measurable (country-level) impact on the transition to renewable energy. Return recently raised €300M to support its growth.
While we employ over 120 people, Return's technical team is still small (15 people). Our platform automates processes in energy storage, monitoring, market optimization, sales, project management, procurement, construction, and customer service. Behind it sits a mix of EU cloud and on-site compute at our battery sites, with strict uptime and security requirements.
During the first four years of operation, we laid the foundation for our platforms, and we are ready to scale up. This is why we are looking for an experienced DevOps engineer who can own the full picture: cloud environments, self-hosted infrastructure at our BESS sites, and the operations centers in Amsterdam and Eindhoven from which we run the fleet.
Your primary focus will be to design, automate, and operate the infrastructure that our virtual battery platform runs on. That means EU-only cloud providers for application workloads, hardened on-premise setups at our sites, and the connectivity in between. You will be the person who decides what gets deployed where, and who makes sure it stays up and stays secure.

During the first three years of operation, we laid the foundation for our platforms, and we are ready to scale up. This is why we are looking for an experienced software engineer.
You will be working on internal tools that support our business departments (origination, development, construction, operation, and general). Our tech stack is straightforward: Postgres, Ruby on Rails 8, Turbo, Stimulus, and Tailwind. We tend to keep meetings to a minimum in order to provide at least five hours of uninterrupted coding time per day. We practice code reviews and apply automated and manual testing. The platform is often deployed multiple times per day.
We’re very much open to remote work as long as you live in the EU. Our hiring process is swift but thorough: a 30-minute call to get acquainted and discuss financials, one or more technical interviews, and a paid visit to Amsterdam to meet the team.
The tech team members have co-founded several companies and have experience with remote development teams since 2008. They will personally help you through most of the recruiting process (there is no recruiter involved).

Interesting, do you also provide the actual audit for ISO 27001 as part of your service? That’s why I went with Oneleet, but a EU-based solution would be attractive.

A cruder version of this was created by the 1001 Crew already in 1986 by the name of ESCOS (Expanded Screen COnstruction Set). There's a video [1] and info page [2].
It was able to import images from KoalaPad, convert, and render it fullscreen using sprites both inside and outside the C64's border.
I will definitely take time to read the full article, it's super interesting at first glance.
