Excited to shape scalable, future-ready Mendix solutions – with end-to-end ownership and real business impact?

At Valcon, we help organisations across Europe become fit for the future – combining consulting, data and technology to realise real transformation. We work end-to-end: from boardroom strategy to concrete implementation on the work floor. Our approach is pragmatic, fast and collaborative. No buzzwords, just results.

Our culture is defined by ownership, entrepreneurship and continuous learning. We believe in growing together – through mentorship, trust and the freedom to shape your own path. We offer flexibility, challenge, and the opportunity to work on projects that matter.

You’ll join our fast-growing Low-Code capability, with over 100 Mendix professionals across Europe – including 26 experts and 3 MVPs in the Netherlands alone. Our team works on high-impact projects for clients like IND/COA, Prorail, Defensie, BAM and Heineken, with a strong focus on collaboration, quality and long-term solutions. Many of our projects are international – such as our recent engagement in Denmark, where our hybrid team (NL, DK, KR) delivers scalable solutions from design to delivery. Whether you want to specialise, coach others or lead engagements – you’ll find the space and support to grow.

Tasks

What will you do?

As a Senior Mendix Consultant, you combine the role of consultant with that of an application developer. You’ll be part of a multidisciplinary project or DevOps team with end-to-end responsibility for your applications and delivery.

You facilitate workshops to uncover client needs and translate them into high-impact IT solutions – from mobile apps to workflow systems and data-driven platforms. Throughout the process, you apply your platform knowledge and technical expertise to ensure quality and scalability.

You take ownership of complex challenges, contribute to design decisions, and help shape long-term platform architecture. As you grow, you’ll have the opportunity to develop towards lead, expert or principal roles – depending on your interests – whether that’s technical depth, mentorship or shaping strategic client engagements.

Among your responsibilities will be the following:

• Designing, developing and testing innovative Mendix solutions in an agile way.

• Coordinating with clients and end-users on specifications, design and final product.
