Postdoctoral Researcher in Structural Analysis for 3D Concrete Printing

IMPORTANT NOTICE – PLEASE READ BEFORE APPLYINGThis position is strictly limited to candidates who meet BOTH of the following requirements:• PhD degree obtained from a Spanish university • Valid legal authorisation to work in Spain at the time of applicationDue to the eligibility rules of the public funding programme associated with this position, foreign PhD degrees are NOT acceptable.Applications that do not fully comply with these requirements will NOT be considered.About AridditiveAridditive is a deep-tech startup working at the intersection of structural engineering, digital fabrication, and sustainable construction. We develop next-generation concrete solutions that challenge traditional construction methods and enable new architectural and structural possibilities.We are looking for a Postdoctoral Researcher in Structural Analysis to join our R&D and Engineering team and play a key role in the structural design, validation, and optimisation of innovative concrete elements.Role DescriptionThe position focuses on structural analysis and design, not on robotics or machine operation. You will work on the structural behaviour of lightweight, non-standard concrete elements, including prefabricated components and systems requiring advanced validation and certification approaches.You will collaborate closely with engineers, designers, and materials specialists, contributing to both applied research and real-world projects.Key ResponsibilitiesStructural analysis and dimensioning of concrete elements such as:Lightweight roofs and slabsStairs and architecturally complex componentsPedestrian elements and prefabricated systemsAdvanced FEM modelling (including nonlinear behaviour, stability, cracking, and failure mechanisms).Definition and evaluation of reinforcement strategies (metallic, non-metallic, fibres, or other compatible systems).Design and assessment of connection systems between prefabricated elements.Interpretation and application of relevant structural codes (EN 1991, EN 1992, EN 1993).Development of internal structural design methodologies and validation frameworks.Preparation of technical reports and structural documentation.Contribution to R&D activities and intellectual property generation.Required Qualifications (Mandatory) ONLY CANDIDATES WHO MEET ALL THE FOLLOWING REQUIREMENTS WILL BE CONSIDERED. APPLICATIONS THAT DO NOT FULLY COMPLY WILL NOT BE EVALUATED.PhD degree obtained from a Spanish university in Structural Engineering, Civil Engineering, Materials Engineering, or Architecture with a clear structural focus. Foreign PhD degrees are not acceptable due to grant elegibility rules.Valid work permit for Spain at the time of application.Strong background in structural analysis of concrete structures.Advanced experience with FEM software (Abaqus, ANSYS, RFEM, SAP2000, MIDAS or similar).Solid understanding of nonlinear behaviour of concrete, including cracking and instability.Experience in the design or assessment of structural connections.Good command of spoken and written English.Availability for on-site work in Barcelona.Only candidates who meet the mandatory requirements will be considered.Valued SkillsExperience with complex or non-standard geometries.Familiarity with digital fabrication or 3D concrete printing (conceptual level is sufficient).Strong technical writing skills (reports, justifications, research documentation).Experience in applied research or innovation projects.Ability to work in multidisciplinary environments.What We OfferA role within a highly innovative R&D project in a fast-growing deep-tech startup.A collaborative and flexible work environment.Direct involvement in projects that aim to transform a traditionally low-innovation sector through technology and sustainability.Real opportunities for professional growth and long-term impact as the company scales.Flexible working hours and a strong culture of technical excellence and initiative.Selection ProcessCV and motivation letter screening.Online technical interview.Research plan presentation (10–15 minutes).Final on-site interview in Barcelona with selected finalists.How to ApplyPlease apply directly through LinkedIn by submitting:Your CV, andA short motivation letter highlighting your relevance for the position.Only candidates who meet the mandatory requirements will be considered.
