- 5 dagen geleden
Leonardo Belgium supports a major European institution operating in the field of diplomacy and international affairs, delivering critical digital services in a complex and security-sensitive environment.
We are looking for a strong Software Engineer to work on highly customized business platforms, such as a heavily modified standalone SaaS-like application based on Odoo 16, and/or other (proprietary) applications developed and maintained internally.
This is not a role limited to a single system. Engineers are expected to contribute where their skills bring the most value across the application landscape.
Job Specifications
Urgent request, early submissions are highly appreciated
Hybrid setting, on site (Brussels) and remote
Type of contract: Freelance (Or able to create a VAT fast)
CV format: Europass preferred
Starting date : ASAP
Eligibly to undergo a Personal Security Clearance (PSC) required
You will contribute to systems within the Digital Solutions Division of a major European Institution. The division develops and operates a broad portfolio of applications covering corporate processes (finance, HR, ...), information management, external policies, and internal services.
Technologies range from modern web platforms and SaaS solutions to internally developed applications running on a cloud-native private infrastructure built around Kubernetes and DevSecOps practices.
The environment includes both modern services and legacy systems, and engineers are expected to navigate and improve both pragmatically.
Responsabilities
Design, develop, and maintain backend services and business applications
Contribute to customized platforms (ERP-based systems and internally developed tools)
Improve reliability, maintainability, and engineering practices
Build integrations across systems, services, and data sources
Investigate and resolve complex production issues
Analyze existing solutions and propose pragmatic improvements
Collaborate in a DevSecOps environment with operations and security teams
Share knowledge and document technical decisions
Experience - Requirements
Software engineering background or experience
Experience or willingness to work on complex, evolving, or legacy systems
Comfortable operating in environments that are not perfectly structured
Hard Skills
Backend development with Python, Java, or PHP
Knowledge of APIs, integrations, and data modelling
Understanding of relational databases (PostgreSQL or similar)
Git or similar version control
Debugging and root cause analysis
What we value
Ownership mindset — you don't wait to be told what's broken
Pragmatism — you can move forward even when things are imperfect
Curiosity — you want to understand how systems really work
Reliability — you can be trusted and act professional
Clear communication across multicultural teams
Nice to have, not mandatory
Strong or native proficiency in French is considered a significant asset.
Experience with Odoo or other ERP platforms
Experience in large organizations or public sector environments
Exposure to container platforms (Docker, Kubernetes)
Familiarity with CI/CD pipelines
Experience with cloud or private cloud environments
What's in it for you?
Work on high-impact systems supporting international operations within a major European institution
Long-term engagement within a wide and diverse technical ecosystem
Hybrid work schedule, with both in-office collaboration and remote flexibility
Exposure to multicultural teams and international stakeholders
Professional growth through training and skill enhancement opportunities
Once we receive your CV, we will evaluate it carefully. Should there be a match for this or any other position at Leonardo Belgium, we will be in touch with you. In case there is no match now, we will make sure to keep your CV in consideration for future vacancies
