About the Role

We are looking for an experienced back-end Python software engineer to join our growing Berlin office. This role will join the Trading Systems Development team, developing best in class back-end services and microservices for our renewables trading platform, with Python and C#.

The team is building a world-class product to help us scale and bring renewables to many more power markets in the world, while trading many more smaller electricity assets. This project is expanding at pace, following Trailstone’s merger with Engelhart Commodities Trading Partners. As a result, this role will be joining an international team with tangible impact on our platform's success from day one.

In addition, this role will own the following responsibilities:

• Design, develop and maintain containerised services for auction-based renewables trading.
• Work in a cross-functional team with engineers, business analysts, traders, data engineers and data scientists.
• Stay up to date with the latest trends in technology and continuously improve our code base, systems, and processes.
• Mentor junior members in the team by emphasising code quality and conducting pull requests and code reviews.

About You

This person will be a seasoned developer, experienced working with time-sensitive hybrid-cloud systems, in order to deliver immediate impact to our growing renewables trading platform. This person will be working closely with commercial stakeholders on a regular basis, so experience collaborating with non-technical staff will help set someone up for success.

We believe the following essential skills & experiences will best set someone up for success in this role, therefore will be prioritising the following:

• Significant relevant Python experience.
• Strong knowledge of object-oriented, functional and asynchronous programming and design patterns.
• Substantial SQL experience and understanding of relational database fundamentals.
• A passion for delivering clean code and working with a test-driven mindset.
• An appreciation of working in a hybrid-cloud and container-driven architecture (partly on-premise and partly AWS).
• Domain knowledge in the energy or financial sector is highly desirable.
• Desirable, but not essential: Experience developing services in C#

Don’t meet every single requirement? Studies have shown that women and individuals from minority backgrounds often hesitate to apply for positions unless they fulfil every requirement. We’re committed to building an inclusive and authentic workplace for everyone. So if this position excites you, but your qualifications or experiences don't perfectly align with the job description, we still urge you to apply. You could be the ideal candidate for this role, or perhaps another opportunity within our expanding business.
