Hydrodynamics Analysis Engineer – Uncrewed Surface Vessel

Location: Hägersten, Stockholm, Sweden; marine operations and offshore work may be required.

Company

hirify.global develops wave-energy technology and systems for the global transition to renewable energy.

What you will do

• Develop hydrodynamic models of the purpose-built uncrewed surface vessel for wave energy converter installation and assess design concepts and changes.
• Analyse vessel motions, seakeeping, stability, operability, hydrodynamic loads, and motion responses to support design decisions and optimisation.
• Perform installation, retrieval, and marine-operation analyses for wave energy converters, mooring systems, dynamic cables, lifting equipment, and deployment tools.
• Use OrcaFlex and related simulation tools to evaluate installation feasibility and operational scenarios.
• Support offshore-operation planning and execution, including installation procedures, risk assessments, method statements, lifting operations, and weather-window analysis.
• Collaborate with mechanical, electrical, controls, and marine teams; participate in offshore operations and pilot installations to validate analyses and improve methodologies.

Requirements

• Degree in Naval Architecture, Offshore Engineering, Mechanical Engineering, or a similar field.
• 2–5 years of experience in marine operations or offshore installation analysis, ideally in offshore renewables, oil and gas, or marine engineering.
• Proven experience with OrcaFlex for dynamic analysis of installation and operational scenarios.
• Understanding of naval architecture principles, including hydrostatics, stability, seakeeping, and hull–equipment interaction.
• Experience with diffraction/radiation tools such as Ansys Aqwa or WAMIT, or with vessel design tools.
• Knowledge of moorings, dynamic cables, lifting equipment, and deployment tools.
• Familiarity with offshore operations planning, vessel capabilities, and marine standards.
• Strong analytical, problem-solving, communication, and collaboration skills, with attention to detail.
• Fluent English, written and spoken.
• Self-motivation, persistence, attention to quality, continuous learning, data-driven decision-making, and the ability to present solutions internally and externally.

Culture & Benefits

• Work in a highly diversified, multinational team focused on renewable energy.
• High degree of autonomy combined with personal responsibility.
• Opportunity to contribute to wave-energy technology and offshore pilot installations.
• Emphasis on excellence, elegant solutions, continuous skills development, and completing work to a high standard.
