You will focus primarily on market modelling of European energy markets, power system optimization, capacity expansion planning, cost-benefit analysis, and economic assessment of infrastructure investments, while also engaging in data handling, visualization, and automation development.\n\nThis role combines technical expertise in energy market fundamentals, analytical thinking, and software development skills to deliver high-quality modelling results and insights for our clients across the European energy sector, including TSOs, regional coordination bodies, and European institutions.\n\nKey Responsibilities\n\nLead and participate in the design, implementation, testing, and analysis of energy market models using tools such as Antares Simulator (including Antares Xpansion for capacity expansion studies).\n\nDevelop and maintain data management, automation, and market modelling pipelines to support large-scale European energy system studies (e.g., TYNDP, IoSN, regional adequacy assessments).\n\nConduct economic evaluations, cost-benefit analyses, and scenario-based simulations to support infrastructure investment decisions and cross-border interconnector assessments.\n\nPrepare and maintain input datasets for market models, including demand profiles, generation portfolios, fuel prices, renewable time series, and transmission capacities.\n\nCollaborate with client teams (TSOs, regional groups, European bodies) to ensure accuracy and consistency in data collection, validation, and central dataset maintenance.\n\nCommunicate modelling results, methodologies, and assumptions clearly to both technical and non-technical stakeholders through reports, presentations, and steering group meetings.\n\nContribute to technical documentation, methodology descriptions, and quality assurance of project deliverables.\n\nRequired Qualifications & Experience\n\n2–7 years of relevant professional experience in energy system modelling, market analysis, or power system planning.\n\n2+ years of proven experience in market modelling and economic analysis of energy systems.\n\nProficiency in Python for modelling, simulation, data processing, and automation.\n\nSolid understanding of European energy market fundamentals: merit order dispatch, zonal pricing, cross-border exchanges, adequacy assessment, and capacity mechanisms.\n\nStrong skills in data handling, processing, and visualization of large-scale energy datasets.\n\nEnglish language proficiency at B2 level or higher.\n\nMSc degree in Electrical Engineering, Power Engineering, Energy Economics, Computer Science, or related field.\n\nDesirable Skills & Assets\n\nExperience with PLEXOS for energy market modelling, production cost simulation, or capacity expansion planning.\n\nKnowledge of open-source energy modelling tools such as PyPSA, Calliope, or OSeMOSYS, and the ability to benchmark or cross-validate results across platforms.\n\nFamiliarity with Antares Simulator and Antares Xpansion for adequacy studies and optimal investment modelling.\n\nKnowledge of optimization theory and mathematical programming (LP, MILP) as applied to energy system planning.\n\nUnderstanding of European regulatory frameworks: ENTSO-E methodologies (TYNDP, ERAA, IoSN), CBAM, EU Green Deal targets, and network development processes.\n\nProficiency in R for statistical analysis or simulation post-processing.\n\nFamiliarity with Git or other version control systems.\n\nAbility to translate customer requirements into actionable modelling tasks and deliverables.\n\nExperience in applying AI tools to support programming and analytical work.\n\nStrong communication and teamwork skills, with the ability to meet deadlines and work effectively in multi-stakeholder project environments.","description_format":"text","description_chars":3885,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"Ukraine","iso":"UA","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":[],"lifecycle":[{"event":"open","at":"2026-11-15T15:41:30Z"}],"visa":[],"liveness":{"score":86,"band":"hot","label":"Hiring
