Give meaning to your career!

Your mission 

• You develop new business opportunities within the Belgian public sector, including federal, regional and local authorities, intercommunales, CPAS and public agencies, selling custom software development, application modernization, our Legacy for the Future (L4F) platform and IT advisory services. 
• You take the time to understand each client’s mission, priorities and constraints before engaging, identifying who is shaping future needs, in order to position 5th Floor’s expertise where it can genuinely add value. 
• You open doors and build a lasting network across decision-makers, influencers and procurement stakeholders, engaging early and ethically to shape opportunities well before tenders are published. 
• You build and run a portfolio of 15 to 25 high-value accounts, with a hunting-first approach, assessing which opportunities are relevant and realistic before committing time and effort. 
• You own the full commercial cycle from first contact to signed contract, managing long sales cycles of 12 to 18 months with discipline and consistency. 
• You bring your client insight and relationship knowledge into bids, contributing to go/no-go decisions, while working in close collaboration with our internal teams, including product and tech experts, marketing, Account Managers and founders. 

Your profile 

• You are a senior business development profile with 8+ years of experience in IT services sales, with an established network within Belgian public sector institutions at federal, regional or local level. 
• You have a proven track record of opening and closing long-cycle B2B opportunities, and you are sharp, structured and execution-minded, with a strong appetite for results. 
• You are skilled in public sector account strategy, using account mapping and ABM approaches, and comfortable navigating regulated procurement cycles. 
• You have a solid commercial understanding of IT services, including software development, application modernization, maintenance, L4F and advisory. 
• You practice consultative selling, diagnosing client needs in depth rather than simply reacting to formalized tenders. 
• You know how to open doors, build trust and engage credibly with decision-makers, influencers and operational sponsors. 
• You operate with real autonomy in the market, while aligning internally at the right moments, and you show commercial discipline and resilience in managing long cycles. 
• You are fluent in French and Dutch; English is an additional working language.
