Lead the technological core of Kerionics: the development and industrialization of the SOEC technology you'll bring to market in ****.

About us
At Kerionics, we accelerate industrial decarbonization through technologies that make cleaner, more efficient energy possible. We are a spin-off from ITQ (UPV-CSIC), born from scientific knowledge with a clear goal: turning research into real industrial solutions. Our SOEC (solid oxide electrolysis) technology produces hydrogen with high energy efficiency where it is needed most: energy-intensive industries such as steel, petrochemicals, cement, ceramics and paper, where replacing fossil fuels remains a major challenge. What we are looking for We need a CTO to lead the development and industrialization of our SOEC technology, with our ***
* go-to-market in sight. Over the coming years we will scale the technology by orders of magnitude. You would join at a critical point: not at the beginning, where everything is exploration, nor at the end, where everything is execution, but where scientific rigor and industrial discipline must coexist every day. We want someone who combines the scientific rigor to solve the open challenges in MEA (Membrane Electrode Assembly), Stack and Balance of Plant (BoP) with the discipline of New Product Introduction (NPI) to take the technology from the lab to an industrial product. Your challenge is not to build a team from scratch, but to take it to the next level: aligning everyone around the roadmap, professionalizing how we develop product and building a technical culture together. You will be the CEO's technical right hand : following the defined strategy and, when needed, challenging it with arguments if you believe something has been decided wrongly. Why this role matters
• Technical leadership of a European deeptech scale-up ,



with technical, commercial and environmental impact at the same time.
• A project with real backing : financial support from deeptech-specialized funds such as InnoEnergy, top-tier industrial and scientific partners, participation in strategic European projects, and new conversations with private investors for the next phase.
• The full transition to market : from prototype to product, from lab to industrial plant, from first customer to deployment. What you will do
• Product development: lead the cross-functional development of our SOEC technology across MEA, Stack and BoP; make sure it follows an NPI logic with clear stage gates, technical pass/fail criteria and traceability of decisions; Team and culture: lead the MEA, Stack and BoP managers directly, unblock what they need, build a technical culture grounded in data, honesty and accountability, and take an active role in technical hiring.
• Critical technical problems: provide top-level judgment on open challenges and lead decisions that cut across areas, even with incomplete data.
• Industrialization and quality: coordinate with the Industrial Project Manager on the future plant, and with the Quality Testing Manager to align validation criteria with the product. Strengthen the development process: consolidate the existing stage-gate system, refining pass/fail criteria, decision traceability and documentation. Bring AI into how the team works ,



where it adds real value, leading by example. Build Kerionics' technical voice externally and position it as a SOEC reference in Europe. How we work We work on-site at Parque Tecnológico de Paterna (Valencia), close to the product: lab, workshop, prototypes and test benches. We usually start early (around 7:30), which leaves your afternoons free for sports, family or whatever you prefer. A PhD will be highly valued.
• At least 5 years in electrochemical or hydrogen technologies (electrolysis, fuel cells or equivalent). Fluent English, spoken and written, for technical discussions and for representing the company.
• Valid work permit for Spain, or eligibility to obtain one. Has the judgment to say no to a good project that doesn't fit the strategy, and yes to a hard one when the evidence supports it.
• Stays current with AI and uses it critically.
• Have been a CTO, VP of R D or Head of Technology in a deeptech scale-up.
• Have lived a complete industrial scale-up (TRL 5-6 to TRL 8-9) in electrochemical, energy or advanced materials technologies.
• Speak Spanish.
• Have your own network in the European hydrogen, SOEC/SOFC or industrial decarbonization ecosystem. Permanent contract , with a standard 6-month probationary period.
• Relocation support package for candidates moving to Valencia.
• 22 working days of holiday.
• Language lessons (Spanish or English) if you want to strengthen your language skills.
• Annual training budget tailored to your needs.
• A video call with our Head of People Culture. A video call with our CEO, to explore your technical vision and how it fits with Kerionics' strategy. A video call with an external expert. A video call with a me
