BiSN is an award-winning technology company specialising in bismuth-based downhole sealing solutions. Our proprietary wel-lok technology has transformed well barrier performance across P&A, Interventions, and Completions. We are seeking an Application Engineer to join our Aberdeen-based team to help deliver tailored, field-ready solutions to complex well challenges. This role is ideal for an engineer who enjoys combining design, testing, and problem-solving with operator engagement.

• Evaluate operator statements of requirement (SORs), well schematics, and completion diagrams to define application parameters.
• Develop tailored tool designs for sealing applications, with input from the engineering and manufacturing teams.
• Use 3D CAD (SolidWorks or equivalent) to produce design layouts, assembly drawings, and tool models.
• Perform engineering calculations and feasibility assessments for field use.
• Collaborate with the R&D, Operations, and Sales teams to align design solutions with field deployment capabilities.
• Support the build and execution of test plans, including hands-on participation in trial assemblies and evaluations.
• Contribute to technical proposals, case studies, and customer presentations.
• Support continuous improvement of standardised product lines and custom designs.

• Bachelor’s degree in Mechanical Engineering or related discipline.
• Minimum 3 years of engineering experience in oilfield tool design, completions, or intervention systems.
• CAD design experience (SolidWorks).
• Comfortable interpreting well schematics, field data, and tool component drawings.
• Understanding of heat transfer, materials behaviour, or pressure control systems is an advantage.
• Hands-on approach to engineering with willingness to get involved in prototyping and testing.
• Strong communication skills with ability to present technical concepts to non-specialists.
• Based in Aberdeen; occasional travel to other BiSN facilities or test sites may be required.

BiSN engineers work on technology that directly solves persistent field problems for some of the world’s largest energy operators. You’ll have access to a fast-paced, technically curious team, with freedom to innovate and test designs that go straight into field use. This is a hands-on engineering environment with global impact.
