Help build the future of the trade.
Sebas works on one goal every day: radically modernising the traditional property management sector. We are an AI agent company: our agents take away all the boring, repetitive work, while you apply your expertise where it truly matters. You supervise, correct and make our AI smarter every week. In no time we have grown into one of the most innovative property management firms in Belgium, and we are only getting started.
At Sebas you work in a fixed team that looks after its own set of buildings, with software we build ourselves. Whether you’re a property manager, an accountant or a technical expert, you get room to make the trade better, and you help shape the tools you use every day. All roles are hybrid, from our Antwerp office.
Open positions
Your role
As a property manager at Sebas you independently manage a portfolio of VMEs. You are the point of contact for owners, the co-ownership council and contractors, but you never stand alone. Our software makes the job far simpler and a shared inbox means you work as a team to keep the workload healthy.
What you bring
You have at least three years of experience as a property manager or in real estate management, and you know VME legislation inside out. You feel at home in front of a room: you chair meetings with authority and calm. You work in a structured way, take initiative, and embrace technology.
Your tasks
- Supervising our AI agents that run the day-to-day management of your VME portfolio.
- Reviewing and correcting AI proposals before they go out to owners and suppliers.
- Chairing general assemblies, the human work AI will never take over.
- Stepping into complex files where the AI gets stuck and your expertise makes the difference.
- Giving feedback that makes our AI smarter every week.
What we offer
You get 20 days of leave, a mobility budget and a competitive salary matched to your experience. You work hybrid: a mix of working from home and our office in Antwerp. You join a young, driven team that genuinely wants to do things differently, with short lines, lots of autonomy and zero corporate bureaucracy. And because our AI takes away all the boring work, you spend your days on the work that truly matters.
Your role
As a lift expert at Sebas you watch over every lift installation in our portfolio. You follow up inspections, maintenance and modernisations and are the technical link between VMEs, lift companies and inspection bodies. Our software gives you a clear overview of every installation.
What you bring
You have a technical background and experience with lift installations at a lift company, inspection body or as a technical manager. You know the applicable standards and regulations, communicate clearly with non-technical people and like working in a structured, independent way.
Your tasks
- Supervising AI agents that follow up lift inspections, maintenance and repairs.
- Technically validating and correcting AI analyses and quote comparisons.
- Site supervision during modernisations, checking the physical reality AI cannot see.
- Solving complex technical files where human expertise is required.
- Feeding back your lift knowledge so our AI gets better every week.

Your role
As an architectural engineer you guide the building-related files of our portfolio: from facade renovations and roofing works to energy master plans. You translate complex technical files into clear advice a general assembly can act on.
What you bring
You are an architectural or construction engineer with experience in renovation or building management. You switch smoothly between site and meeting table, write clearly and love pragmatic solutions that also make budget sense.
Your tasks
- Supervising AI agents that prepare technical files and multi-year plans.
- Validating and correcting AI-generated specifications and quote comparisons.
- Visiting sites and checking the reality AI cannot see.

Your role
As an accountant at Sebas you manage the finances of a portfolio of VMEs. Transparency is our promise to owners, and you deliver it daily with correct settlements, clear budgets and punctual payments. Our software automates the repetitive work; you focus on quality.
What you bring
You hold an accounting degree and preferably have experience with VME or real estate accounting. You work accurately, hit deadlines without stress and enjoy explaining numbers in plain language to non-accountants.
Your tasks
- Supervising AI agents that run the day-to-day VME accounting.
- Reviewing and correcting AI-booked invoices, settlements and budgets.
- Solving the complex cases: disputes, arrears and exceptions.
- Validating financial reporting before it goes to the general assembly.
- Giving feedback that makes our accounting AI more accurate every week.

- Negotiating premiums and complex claims, the human work.
- Stepping in where files get stuck and your expertise makes the difference.
