Chief Technology Officer (M/F/X) - Permanent Contract Full-Time – Belgium/Netherlands (hybrid) - Leadership Role Our client is an innovative European university spin‑off working on sustainable, self‑healing polymer materials for the tyre and wider polymer industry. The project is moving from academic research into a private scale‑up phase, with the goal of bringing this technology to the market.
The team has already produced up to 100 kg of material and is working with industrial partners to test and develop real‑life applications. The focus is on turning strong scientific results into practical solutions that help products last longer and reduce environmental impact.
The team works in a scientific way, with a flat structure and no corporate layers. People work closely together, combining research and experimentation in a collaborative and dynamic environment. The spin‑off is looking to grow with professionals motivated by cutting‑edge technology and sustainability.
About the role This is a leadership role that combines scientific expertise with operational responsibility. It requires strong technical judgment, the ability to make timely, well‑judged decisions and to present our technology externally with confidence.
The CTO will lead the technical organisation end‑to‑end: materials R&D, laboratory and scale‑up testing, validation and qualification, industrialisation, and technical partnerships. He/She will also translate the material platform into qualified, approved, and market‑ready products, starting with bike tyre manufacturers and distributors.
Challenges of the role The main challenge is to turn an advanced technology into a real product.
Redevelop polymers that enable room‑temperature curing
Achieve proper adhesion to all types of tyres
Ensure the polymer is extrudable with high quality (1–2 mm thick, 20–30 mm wide)
Preserve properties after undergoing the tyre vulcanisation process (the polymer packed into the tyre)
Leverage industry partnerships to solve these challenges
Key responsibilities Lead the materials science team (formulation, synthesis, processing, performance optimisation)
Drive manufacturing of self‑healing polymer across formats (e.g. tapes, coatings, integration pathways)
Define technical strategy and priorities based on performance targets, manufacturability, cost and customer needs
Testing, validation & approvals (lab to scale‑up) Own the testing strategy across lab, pilot, and industrial‑scale testing (robustness, QC, reproducibility)
Build and lead the testing and validation team
Define and run test protocols that directly support customer qualification and approval
Establish quality‑by‑design testing and data integrity, acceptance criteria, sampling plans, statistical thinking and traceability
Program management & execution Implement project planning and execution rhythms (roadmaps, milestones, risks, dependencies)
Maintain dashboards for leadership and investors, tracking progress, risks, and mitigation plans
Ensure cross‑functional alignment between R&D, testing, commercial teams and external partners
IP & patent strategy Own the technical side of IP strategy, including invention disclosures, drafting support, and prosecution follow‑up with counsel.
Coordinate Freedom‑to‑Operate analyses and competitive monitoring.
Ensure IP capture is embedded into R&D workflows and partner collaborations (confidentiality, ownership, background/foreground)
Technical partnerships Develop and manage technical partnerships with: chemical producers and processors (raw materials, toll manufacturing, coating/tape processing, scale‑up)
customers (bike tyre manufacturers and distributors) for trials, qualification, and integration routes
Represent the company as the trusted technical expert in partner discussions forums
What success looks like in the first 6–18 months You will measure your success by:
Establishing a robust R&D, testing, and scale‑up operating system with clear plans, KPIs, documentation and decision gates
Delivering validated performance data and repeatable manufacturing and test protocols that support customer trials
Driving customer approval through a clear qualification path, accepted test results, and commercial readiness
Strengthening the IP pipeline with regular invention capture, a clear prosecution roadmap, and Free to Operate (FTO) position
Building a scalable partner network for manufacturing and processing
Finalising a market‑ready product, including specifications, packaging, QC plans, claims, and documentation ready for sales
Upscaling the product toward ~10‑tonne production with defined processes, supplier/toller readiness, QC release specifications and demonstrated reproducibility
This role is for you if You bring proven industry R&D leadership, including team management, budgeting, prioritisation, and product delivery through validation.
You have strong expertise in materials science, polymer chemistry, chemical engineering, or a related field.
You can structure and drive complex technical programs across multiple workstreams.
You have experience with patents/IP in an industrial setting (invention, capture, counsel interface, strategy input, FTO familiarity).
You communicate clearly and credibly with scientists, customers, and investors.
You are a top candidate if You hold a PhD in polymer chemistry, materials science, chemical engineering, or a similar field.
You have experience with industrialisation, scale‑up, toll manufacturing, or product qualification.
You have exposure to tyres, rubber, coatings, sealants (nice to have).
You have supported customer qualification processes and technical commercial discussions.
This role is not for you if You need guaranteed outcomes.
You are uncomfortable with experimentation and uncertainty.
You want a desk‑only role with minimal lab involvement.
Why join our team This is a rare opportunity to take a key leadership role in a spin‑off company with real industrial traction and meaningful impact.
You will have the freedom: to shape the technical roadmap
structure the organisation
build a partner ecosystem that drives innovation and growth
What we need: a leader, not a boss You learn fast and can master complex science while keeping the business picture in mind.
You are structured, decisive and comfortable making choices in uncertain environments.
You can build and coach high‑performing teams and set clear standards.
You are a strong partner to the CEO and business development teams and are comfortable representing the company externally.
What we offer Very early‑stage opportunity: small team (~7 people)
Secured public funding (>€1M) and active investor discussions
High scientific autonomy within a clear framework
Stock‑option plan to participate in the company’s upside
Competitive compensation package aligned with your impact and company stage
Reimbursement of 157,8 euros replacing internet fees
