Location: 

Porsgrunn, Telemark, NO, 3936

Career area:  Research & Development
Department: 
Job Type:  Permanent
Apply by:  Sunday April 12, 2026, by midnight CET

Hydro is a global aluminium company striving to be a leader in working towards a sustainable future. In December 2021, we announced our plans to develop and industrialize HalZero, a new CO₂ emission-free process for producing primary aluminium.

The development of HalZero is one of three pillars in Hydro’s initiative to deliver aluminium with net-zero CO₂ emissions. HalZero is a new and innovative way to produce aluminium, where no CO₂ is emitted during the production process. In December 2025, we completed construction of the HalZero Test Facility in Porsgrunn. Industrializing the HalZero process requires extensive development, including laboratory work, design and operation of our Test Facility and pilots, and engineering and construction of demo and full commercial plants.

The work towards CO₂ emission-free aluminium is led by the Technology, Operational Support and Projects (TOP) unit in Hydro Aluminium Metal. TOP consists of 300 skilled employees in Norway and Germany, whose main task is to support commercial and operational units in improving profitability and sustainability both in the short and long term. HalZero is strengthening its team in several areas to support the further development of the technology. 

We are looking for an experienced Senior Chemical/Process Engineer to strengthen our Process Development & Engineering department. In this key technical role, you will help develop, optimize, and industrialize our process technology while supporting safe, efficient, and reliable plant operations.

What we offer you

  • A key technical role in a growing and innovative organization
  • Work with advanced process technology and industrial scale development
  • Be part of major development and industrialization projects
  • Join a collaborative team with strong technical expertise

What you will be doing

You will work across the full lifecycle of process systems — from design and development, through project execution and operational support — collaborating closely with test facility operations, technology development, project teams, external engineering partners and suppliers.

Key responsibilities include:

  • Lead and contribute to process design, optimization, and troubleshooting
  • Develop and maintain process documentation (PFDs, P&IDs, mass & energy balances)
  • Perform process simulations and engineering calculations
  • Provide process input to engineering studies, FEED, and detailed design
  • Support HAZOPs, design reviews, and technical assessments
  • Lead or support plant modifications, debottlenecking, and reliability improvements
  • Provide technical process support to operations, including troubleshooting and performance monitoring
  • Collaborate with EPC contractors, equipment suppliers, and engineering partners

What will make you successful?

  • MSc or BSc in Chemical or Process Engineering (relevant experience may compensate)
  • 10–15 years of experience in process and/or systems engineering within industrial or chemical process environments
  • Strong experience with process and equipment design, process control, simulations, and engineering calculations
  • Experience from engineering projects, plant modifications, commissioning, or operations support
  • Familiarity with process safety reviews (HAZOP) and multidisciplinary project work
