Job Opening: We're looking for a number cruncher

No items found.

Our mothership Onkruid Studio is looking for extra hands. Or brains to be more precise. Onkruid Studio develops projects at the intersection of music, art, architecture and urban development. Through initiatives such as Horst Arts & Music and Asiat Park, we create spaces where culture, experimentation and human connection can thrive. Behind these projects lies a financial operation that deserves just as much attention. That’s why we’re looking for a Financial Controller who can bring structure, ensure reliable financial data and look ahead. Someone who is equally comfortable checking an invoice and analysing a project budget, and who is eager to help build a creative organisation. Discover the job opening below.

What will you do?

You will help manage the day-to-day financial operations of Onkruid Studio and its projects. You combine a solid accounting foundation with an understanding of cash flow, budgets and financial performance. You ensure that information is available on time and translate financial data into actionable insights for the team.

Financial administration and payments

- You are responsible for the internal accounting of all organisations within Onkruid Studio.

- You manage purchase and sales invoices, ensuring they are processed, recorded and allocated to the correct budgets.

- You organise outgoing invoicing, follow up on outstanding customer payments and monitor payment deadlines.

- You prepare payment schedules based on available cash flow and agreed priorities, and prepare payments for approval.

- You coordinate with the external accountant, ensuring that all documentation is complete and ready on time for financial closings and tax filings.

Reporting, cash flow and budgets

- Together with the external accountant, you ensure reliable and timely monthly financial reporting.

- You update cash flow forecasts on a weekly basis, flagging potential shortfalls, risks and changes in advance.

- You monitor project budgets together with project managers. You combine actual costs, committed expenditure and expected income to maintain an up-to-date overview of projected final results.

- You investigate variances and identify where adjustments are needed.

- You support the Financial Director in preparing financial forecasts and providing the financial analysis required for funding applications.

Systems and events

- You oversee the financial setup and data quality of our systems (Odoo), with a focus on analytical accounting, project codes and consistent data processing.

- You improve processes and establish clear agreements on who provides which information and when.

- You organise cash management for events, from preparation and monitoring to reconciling cash and payment records and completing the financial settlement.

- You help identify the administrative support required and organise the division of tasks to ensure timely processing and reporting.

Who will you work with?

- You will work closely with the Financial Director and Managing Director on priorities, financial monitoring, quality control, forecasts and funding applications.

- You collect and connect information from across the business team. Together with project managers, you monitor budgets and expected results. The external accountant will be your regular partner for accounting and tax-related matters.

Who are you?

- You have a solid foundation in accounting and experience in accounting, controlling or a broad financial role. We have at least three years of experience in mind, but your independence and skills matter more than the exact number of years.

- You combine accuracy with analytical thinking. You understand how accounting, project results and cash flow are connected.

- You are confident using Excel or Google Sheets and financial software. Experience with Odoo is a strong asset.

- You bring structure, follow up on agreements and proactively request missing information.

- You communicate clearly about financial matters, including with colleagues who do not have a financial background.

- You flag potential issues early and help develop practical solutions.

- You feel at home in a project-based environment with diverse activities and busy periods. Experience in culture, events or an organisation with multiple legal entities is a plus.

- You have an affinity with what Onkruid does. You don't need to come from the sector, but you are curious about the work behind our projects.

What do we offer?

- A varied financial role with a tangible impact on our projects and day-to-day operations.

- A committed team with diverse expertise in culture, production, spatial development and organisational management.

- The opportunity to improve processes and help shape our financial operations.

- Direct communication with management, project managers and the external accountant.

- A workplace at Asiat Park in Vilvoorde, close to the projects you will be contributing to.

- A full-time position under the terms and conditions of Joint Committee 304 (PC 304).

Preferred start date: 1 November 2026.

Horst Arts & Music is headed for new territories in 2025. Our festival grounds are expanding across the Zenne, for which a new pedestrian bridge will be built.

Leading architect Sumayya Vally, Principal of the Johannesburg/London-based studio Counterspace, has won the competition to design this new bridge in Vilvoorde, Belgium. The Asiat-Darse bridge is a project initiated by the city of Vilvoorde and Horst Arts and Music. It is financed by Kunst in Opdracht at the Flemish Ministry for Culture, and ANB, the Flemish Agency for Nature and Forest who partnered with DVW, the Agency for Flemish Waterways. Curator Heidi Ballet is artistic advisor for the project.

Counterspace’s response to the brief uncovered the story and legacy of Paul Panda Farnana, one of the most important, yet least acknowledged figures of the city, who epitomises the region’s complex relationships with past and future generations of migrant bodies and communities.

Sumayya Vally said: “Vilvoorde is a city celebrated for its diversity. It comprises multiple cultures, identities, and narratives. I was deeply moved to uncover the story of Paul Panda Farnana through our research, which then drove our response to the city’s brief for a pedestrian bridge. Trained as a horticulturist at the Vilvoorde Horticultural School not far from the site, this project will revive Farnana’s legacy by foregrounding the concept of the species explored in his research, alongside water architectures from the Congo.”

Vally took inspiration from water architecture of the Congo as one of the starting points to honour this history. Along the Congo River, fleets of dugout canoes are frequently seen docked alongside one another. As a collective, they form a communal platform, from which trading and gathering can take place. These images form the basis for the proposed Asiat-Darse bridge, itself a place of gathering of travellers, whether commuters or visitors. The bridge is constructed of a series of boats tied together to cross the canal.

“Trained as a horticulturist at the Vilvoorde Horticultural School not far from the Asiat site, this project will revive Farnana’s legacy by foregrounding the concept of the species explored in his research, alongside water architecture from the Congo.”

— Sumayya Vally

Vally looked at plants and species to honour Farnana’s horticultural work. Each ‘boat’ form serves as an isolated seed bed, in which specific plants can be cultivated in order for their seeds to be spread on the wind, and carried on the bodies of people travelling across the bridge. As a result, the bridge pays homage to Farnana’s horticultural work, serving as a nursery, or seeding bed from which plants may distribute themselves, migrating across the site.

In addition to the main structure, several smaller boat structures are proposed, which embed themselves along the river bank. Each of them will be named after the labourers whose names were included on the register from the Congo, which the studio discovered in their research. Every boat will act as a pollinator - pollinating an industrial zone and acting as a little garden for reflection for passers-by to rest in.

“A bridge is a connector - in our project, it is a connector to past and future narratives of migration too. It is my hope that this project helps to embody and raise awareness on the story of Farnana, and that it reminds us as architects that we have to listen deeply to the grounds of the contexts we work in. There is always architecture waiting to happen in places that are overlooked.”

ABOUT SUMAYYA VALLY

Sumayya Vally is Principal of Counterspace—an award-winning design, research and pedagogical practice searching for expression for hybrid identities and territory, particularly for African and Islamic conditions—both rooted and diasporic. Her design process is often forensic, and draws on the aural, performance and the overlooked as generative places of history and work.

In 2022, Vally was selected by the World Economic Forum to be one of its Young Global Leaders, a community of the world’s most promising artists, researchers, entrepreneurs, activists, and political leaders, and, as a TIME100 Next list honoree, has been identified as someone who will shape the future of architectural practice and canon. She has joined the World Monuments Fund Board of Directors, and serves on several boards through her interest in dynamic forms of archive, embodied heritage, and supporting new networks of knowledge in the arts. The Royal Architectural Institute of Canada inducted Sumayya into its 2023 Honorary Fellowship, which recognises individuals that exemplify the tremendous impact that architects have—not only on the built environment, but also on public life and the world around them.

In 2019, Counterspace was invited to design the 20th Serpentine Pavilion in London, making Vally the youngest architect ever to win this internationally renowned commission. Vally is also the Artistic Director of the inaugural Islamic Arts Biennale in Jeddah.
