Odoo Software Developer (H/F/X)

Leonardo Belgium is seeking an Odoo Software Developer to support a prestigious European institution at the forefront of global diplomatic strategy. You will join a growing Odoo team working on a highly customized Odoo 13 environment, primarily focused on HR and Payroll management.

This is not a standard Odoo implementation: the system was migrated from legacy platforms and has since evolved into a standalone SaaS-like solution. Customization is at the core of this role — the ideal candidate is pragmatic, adaptable, and curious, not a strict Odoo purist.

Job Specifications

• Hybrid setting, on site and nearby (Brussels)

• Type of contract: Freelance (Or able to create a VAT fast)

• CV format: Europass

• Starting date : ASAP

• Eligibly to undergo a Personal Security Clearance (PSC) required

• Urgent request, early submissions are appreciated

As an Odoo Developer working within a multidisciplinary ERP team, you will :

• Develop and customize high-quality Odoo modules with a strong focus on HR and Payroll

• Design and maintain integration interfaces with internal and external systems (REST API, FastAPI, xml-rpc, json-rpc)

• Participate in functional and technical analysis to ensure that customizations meet business requirements

• Implement best practices in data modelling, business logic, code quality, and unit testing

• Support team members as a technical expert, helping to resolve issues and translate complex business processes into effective Odoo solutions

• Troubleshoot, debug, and document solutions in a clear and maintainable way

Experience - Requirements

• Proven experience with the Odoo Framework (large-scale or highly customized environments preferred)

Hard Skills

• Proficiency with Python, PostgreSQL, and JavaScript

• Experience with REST APIs and third-party integrations

• Knowledge of QWeb templating, GitHub, and relational database concepts

Soft Skills

• Pragmatic and adaptable mindset — comfortable working in a heavily customized ERP rather than a “textbook” Odoo project.

• Strong analytical and problem-solving skills

• Eager to learn, self-driven, and comfortable in an international, multicultural team

• Team spirit and clear communication skills across multicultural, multilingual teams

• Ability to learn quickly and adapt to evolving technical environments

Nice to have, not mandatory

• Knowledge of EU institutions and decision-making processes

• Specific expertise with Odoo ERP in HR and Payroll projects

• Awareness of the Odoo Community Association (OCA) ecosystem

• Odoo front-end development skills (Bootstrap, CSS, Sass, …)

• Experience with Odoo server administration

• Knowledge of Oracle 19c

What’s in it for you?

• An opportunity to contribute to a high-impact EU project in a dynamic and fast-growing environment

• A chance to work on challenging customizations that go beyond standard Odoo development

• 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
