Lead Solution Architect – Technical Lead

This is a long-term freelance assignment for a Lead Solution Architect to join the architecture team of a large organisation in the public sector in Brussels. The work model is 2 days per week onsite. The language requirement is French + English OR Dutch + English. You will become the technical reference for a team of 8-9 experienced Solution Architects, taking the lead on architectural decisions while remaining close enough to the technology and development teams to challenge technical choices, review solutions and provide hands-on architectural guidance.

The organisation is looking for someone who can combine deep technical expertise with strong leadership and communication skills – someone who can challenge experienced architects and developers, but also confidently defend architectural decisions at Board and business level. As Lead Solution Architect, you will act as the technical reference point, take the lead on complex architectural decisions and defend them towards the Architecture Board and business stakeholders, define, evolve and enforce architectural principles, standards and best practices, challenge architectural choices made across multiple projects and Scrum teams, support Solution Architects in solving complex technical and architectural problems, participate in architecture reviews and contribute to the organisation’s technology roadmap, work closely with development teams and remain technically credible with senior developers and technical leads, review technical designs and participate in code reviews, guide teams through technology choices, integration patterns, security considerations and architectural trade-offs, provide architectural leadership across a combination of legacy modernisation and new technology initiatives, and act as a natural leader within the architecture community without direct people-management responsibility.

The ideal candidate brings significant experience in Solution Architecture / Software Architecture, a strong technical background in Java, good understanding of Angular / modern application architectures, strong knowledge of application integration and security, experience with both legacy and modern architectures, experience in large-scale multi-project organisations, the ability to challenge technical decisions and communicate complex subjects clearly, experience interacting with senior management or architecture boards, credibility with developers and technical leads, strong leadership and influencing skills, and excellent English communication skills.

French or Dutch is a plus. The ideal candidate is someone who is already considered a technical reference by the people around them, comfortable moving between Developer, Architect, Architecture Board and Business without losing credibility at any level.
