CIC energiGUNE is a research center specialized in energy, electrochemical storage (batteries and supercapacitors), thermal energy solutions and hydrogen, a member of the Basque Research and Technology Alliance- BRTA, and, a strategic initiative of the Basque Government. CIC energiGUNE was created in 2011 to generate excellent knowledge and at the same time useful for the Basque business network, being a reference in knowledge transfer.

CIC energiGUNE has a dynamic research team of more than 100 researchers and is extremely well equipped with a wide range of up-to-date facilities that are fully available for all its researchers. Also, the European Commission has recently (2019) awarded CIC energiGUNE with the ´HR Excellence in Research´ which reflects its commitment to achieving fair and transparent recruitment and appraisal procedures and certifies the existence of a stimulating and favorable work environment for researchers in the institution.

The Cell Prototyping group at CIC energiGUNE is searching for a Postdoctoral Researcher or Process Engineer to engage in the research and development of sustainable sodium ion capacitors within a recently granted Horizon EU project.

The role of the selected candidate will be focused on the development of sodium ion capacitor pouch cell prototypes, covering the whole process: from electrode formulation and optimization to manufacturing at pilot line and prototype assembly for electrochemical characterization and validation of the technology.

Main responsibilities of the candidate will include:

  • Definition and optimization of electrode recipes to reach cell energy and power performance targets, including ink formulation, mixing, coating, drying and calendering of electrodes.
  • Deliver feedback to RLM and GL to guide material optimization and processability which is aligned with final use requirements
  • Physicochemical characterization of inks and electrodes.
  • Assembly of laboratory cells (coin, Swagelok) for the electrochemical characterization of electrodes.
  • Transfer existing R&D processes from lab scale to pilot line.
  • Assembly and electrochemical characterization of pouch cell prototypes for technology validation.
  • Post-mortem analysis. Investigate cells failure mechanisms and perform root cause analysis to create mitigation plans
  • Contribute to the development of intellectual property


We are offering a 36-month contract and advantageous professional development opportunities with the possibility of renewal based upon satisfactory job performance, continuing availability of funds, and ongoing operational needs.

Access to a complete set of existing laboratory infrastructure and equipment to ensure a fruitful stay and the fullfilment of the objectives in due time. 

Candidates will join an integrated, enthusiastic, and multidisciplinary institute making high quality research and impactful contributions to the energy and sustainability fields.

CIC energiGUNE will also help smooth the transition for you and your family, providing a welcome program that offers help with accommodation and addresses other aspects to help you integrate into the local environment (such as free language courses, help with schools for children…).

CIC energiGUNE is located close to the city of Vitoria-Gasteiz (Spain), in the heart of the Basque Country. The Basque Country is the region with the highest R&D investment in Spain, with more than 20.000 researchers. The basque research ecosystem comprises a solid and collaborating community composed of universities, technology and cooperative research centers.
