Return | REMOTE | BESS Optimization Developer (Python) | Full-time

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).

FusionAuth | Principal Software Engineer, Senior Java Engineer - Cloud, Account Executive, Solutions Engineer | Varies between REMOTE (in USA, also in Europe but only for the account exec/solutions engineer positions) and ONSITE in Denver, CO, USA, details in each job desc | Salary ranges for the Principal Software Engineer it is 225k-270k, but the Euro positions don't have them :(

At FusionAuth, our mission is to make authentication and authorization simple and secure for every developer building web and mobile applications. We want devs to stop worrying about auth and focus on building something awesome.

There are a lot of companies in the auth space, but we feel like we have something special:

* a relatively unique deployment model (self-host on-prem, run in your cloud or let us operate it for you in ours)

* A well designed API first approach; one customer compared our APIs to petrichor

* a mature product (the code base is nine+ years old and we've found and fixed a lot of the sharp edges around core login use cases; but don't worry, there are plenty more features to add)

* a full featured free-as-in-beer version which makes the sales cycle easier; prospects often come in having prototyped an integration

Our core software is commercial. We open source much of our supporting infrastructure. Technologies and standards that you will work with: modern Java, PostgreSQL, Docker, Kubernetes, MySQL, OAuth, SAML, OIDC.
