  • Analyze simulation data, creating comprehensive reports and presentations for internal stakeholders indicating areas of concern and recommending design changes
  • Support an interdisciplinary team in the development of an in-house 6-degree-of-freedom (6-DOF) vehicle simulation model to predict performance, optimize control systems, and assess new functionalities
  • Stay current with advancements in CFD techniques and underwater vehicle technology


Required Qualifications:

  • Bachelor’s degree in Mechanical Engineering, Aerospace Engineering, Naval Architecture, or a related field (Master’s preferred).
  • Demonstrated experience in CFD analysis, particularly in marine or underwater applications.
  • Proficiency in CFD software such as ANSYS Fluent, COMSOL Star-CCM+, Solidworks Flow, Numeca, or OpenFOAM.
  • Experience with CAD software such as Solidworks (preferred), CATIA, NX, or similar.
  • Strong analytical skills and attention to detail
  • Excellent communication skills with the ability to present technical findings clearly to cross-functional teams.
  • Team player who is proactive in problem-solving and thrives in a fast-paced environment.
  • Passion for marine technology and the future of autonomous underwater systems.
  • Interest and availability to transition to a full time position with Vatn Systems


Preferred Qualifications:

  • Experience with 6-DOF simulation models and system identification for underwater vehicles.
  • Familiarity with parametric optimization in solid modeling and simulation
  • Background in control systems or vehicle dynamics for AUVs or underwater robots
  • Portfolio of previous projects exemplifying the above qualifications
