Location: Portland, Oregon, with exceptional remote candidates considered; regular travel to Portland is expected. Legal authorization to work in the United States is required. Relocation assistance to Portland is available if needed.

Salary: $155,000–$200,000 per year, plus company equity.

Company

hirify.global is a public benefit renewable energy and ocean technology company developing ultra-low-cost ocean energy technologies for computing and renewable fuels.

What you will do

• Lead CFD-based performance validation for optimized marine system designs, including geometry preparation, meshing, solver setup, debugging, post-processing, visualization, and reporting.
• Run and improve workflows using Helyx, OpenFOAM, and/or Star-CCM+ across complex marine operating conditions.
• Evaluate power, propulsion, hydrodynamic loading, device performance, and other engineering metrics.
• Compare CFD results with reduced-order models, BEM and time-domain simulations, experimental data, sea-trial measurements, and metocean observations.
• Develop automation pipelines, reusable simulation templates, dashboards, technical memos, and technical presentations.
• Collaborate with optimization, controls, mechanical engineering, metocean, fleet simulation, and experimental teams to connect predicted and measured performance.

Requirements

• Legal authorization to work in the United States.
• Bachelor’s degree in Ocean Engineering, Naval Architecture, Mechanical Engineering, Aerospace Engineering, Physics, Applied Mathematics, or a similar field.
• Significant experience running end-to-end CFD simulations for real engineering systems and experience with at least one RANS-based CFD tool.
• Strong knowledge of fluid mechanics, marine hydrodynamics, rigid body dynamics, physics-based modeling, and CFD verification and validation.
• Experience diagnosing meshing, boundary-condition, convergence, numerical-stability, turbulence-modeling, and post-processing issues.
• Working knowledge of Linux, scripting workflows, and HPC-based simulation execution, with strong technical communication and project ownership skills.

Nice to have

• 5+ years of experience in CFD, marine hydrodynamics, naval architecture, offshore engineering, turbomachinery, propulsion, or related fields.
• Experience with marine CFD, free-surface or multiphase flows, fluid-structure interaction, propulsion, wave-structure interaction, or metocean environments.
• Multiple CFD tools and solver development experience, especially with Helyx or OpenFOAM.
• Programming experience with Python, C++, Julia, Java, Bash, or similar engineering languages.
• Experience with physical test data, metocean datasets, CAD-to-CFD workflows, dashboards, technical mentorship, or startup R&D environments.

Culture & Benefits

• Work in an idea-meritocracy focused on rapidly deploying sustainable ocean energy technologies.
• Full-time employees receive equity in the company.
• Flexible paid time off and health, dental, vision, and disability insurance are provided.
• Benefits include 401(k), health FSA, and dependent care FSA contributions.
• Occasional extended hours or weekend work may be required for milestones, sea trials, fleet operations, or urgent design decisions.
