Solution Architect - B2B, Finance, Corporate Development

Architect the platforms that power Belgium’s businesses every day. 

Telenet Business is in the middle of a major transformation. Multiple tribes simultaneously rebuilding how we sell, serve, bill and support our SME and Large Enterprise customers. The opportunity is huge; the risk of structural fragmentation is real. That’s where solution architecture comes in. 

You’ll join the Solution Architecture team for B2B, Finance and Corporate Development. Most of your work will sit in the B2B circle: multiple tribes building the future of how Belgian businesses connect, work and pay. But you’ll also touch the systems that keep the company running: finance flows, procurement, billing platforms, and the corporate development work that shapes where Telenet goes next. 

Your job is to keep that future coherent. Making sure each new initiative fits the bigger picture, that we reuse capabilities instead of duplicating them, and that simplification actually happens instead of being talked about. 

You’ll lead or review the architecture for initiatives across their full lifecycle, from a half-formed idea to a design the delivery teams can build with confidence. You’ll be the person who makes assumptions explicit early, surfaces dependencies before they hurt, and challenges deviations that would create technical debt nobody wants to inherit. 

Your responsibilities as Solution Architect 

You won’t spend your days drawing boxes nobody reads. You’ll be in the room where the decisions get made. Pushing back when a requirement doesn’t add up, surfacing trade-offs nobody else has spotted, and turning fuzzy business ambitions into designs the delivery teams can build with confidence. 

Concretely, you will: 

• Run high-level impact assessments early on. Pinpoint which applications and capabilities are affected, sketch the rough cost and complexity, and give decision-makers what they need to decide whether an initiative is worth pursuing. 
• Develop and compare solution alternatives. Lay out viable options, weigh them honestly on cost, complexity and time-to-value, and help the business pick the right one. 
• Own the detailed end-to-end solution design once an alternative is chosen: current state, target state, the transition path between them, and any conscious deviations from our architectural guardrails. 
• Sit down with business stakeholders, product owners and engineers to understand what they really need (which is rarely what they first ask for). 
• Keep cross-tribe initiatives coherent. Make sure new capabilities fit the agreed end-to-end operating model and that sequencing, readiness and dependencies are explicit before they become surprises. 
• Keep our architecture repository and LeanIX up to date. Your designs are the reference that delivery teams, partners and decision-makers rely on. 
• Drive sustainable landscape simplification. Challenge unnecessary duplication, promote reuse, and help prevent new technical debt before it gets baked in. 
• Map the full cost picture (build, run, change) and help the business define what “good enough to ship” looks like. 

Your profile as Solution  Architect 

• You’re a strong communicator who actually enjoys the messy human side of architecture: aligning stakeholders, translating jargon, building bridges between business, IT and delivery. 
• You can hold the big picture and the technical detail in your head at the same time. Comfortable enough with application systems and SDLC to challenge a development team’s design, abstract enough to draw the landscape view. 
• You’re comfortable working across multiple teams and programs at once. Cross-tribe coordination doesn’t intimidate you; it’s where you do your best work. 
• You like agile, autonomy and small teams that move fast, and you’re at home in an environment that’s continuously changing. 
• You’re curious by default. B2B telecom services, finance flows, corporate platforms: there’s always more to learn, and that excites you rather than tires you. 
• You think forward. You’re not just solving today’s project; you’re nudging the landscape towards where we want it to be in three years. 
• You bring a bachelor’s or master’s degree and at least 3 years of hands-on enterprise solution architecture experience. 
• You speak fluent English. Knowledge of the telecom operating model is a real plus, but if you don’t have it yet, your appetite to learn it is what counts.
