Our mission is to provide innovative services critical to society, unlocking a cleaner, better, and more profitable future.

We are now looking for a Software Engineer who can help us to continuously improve Volue’s ability to provide value to customers in line with the Volue mission.

What you will be doing to make a difference:

• Build and evolve dispoPower and dispoGas, cloud-native Java Spring Boot applications that handle mission-critical energy nomination and scheduling messages between energy companies and European TSOs

• Implement and maintain integrations with TSO systems using protocols such as AS4 (ENTSOG/BDEW) and ECP networks, ensuring reliable and compliant message exchange across Gas and Power markets

• Work across the full message lifecycle: time-series ingestion, validation, XML generation, protocol dispatch, acknowledgement handling, and real-time anomaly and discrepancy detection

• Contribute to platform modernization, Spring Boot upgrades, test automation, API layer development, and automated tenant onboarding

• Collaborate closely with domain experts and product owners to translate European energy market requirements into robust, maintainable software

• Optionally contribute to our React/TypeScript frontends, operational dashboards that give energy dispatchers real-time market visibility

What you need to succeed:

• At least 3+ years of professional software development experience

• Strong Java skills with Spring Boot - this is the core of everything we build

• Solid understanding of RESTful API design and relational databases (PostgreSQL or similar)

• Comfortable working in a cloud environment, ideally Azure

• Ability to work independently and take ownership in a small, agile team

• Good English communication skills (at least B2 level)

Nice to have

• React/TypeScript experience, if you can contribute to the frontend as well, that's a real plus

• Familiarity with energy markets, scheduling protocols, or XML-based messaging standards (ENTSOG, BDEW, ECP)

Reasons to join Volue team and what we offer:

• Large degree of influence in shaping & developing the role further

• Great colleagues in one of Europe’s most exciting green tech companies with innovative and international work environment

• Flexible working hours  & competitive compensation package

In Volue, we cherish each employee’s competence, ideas, and personality. Let your skills and talent be a part of our team – and let us leave our mark on the world together!
