Biosort

Fornebu

At Biosort, we develop cutting-edge solutions that combine machine vision, robotics, and biometric data to enable individual treatment and monitoring of farmed fish. Our products are installed underwater in salmon cages and contribute to improved fish welfare, increased sustainability, and lower production costs for fish farmers.
We are now strengthening our product development team with an experienced Mechanical Engineer who can design robust electro-mechanical modules for marine environments, take prototypes through testing, and prepare them for reliable volume production. If you love solving hard engineering problems and want your work to have real-world impact in the ocean, this is the role for you.
What you’ll do
<ul><li>
Design electro-mechanical products with up to 5000 parts and fasteners over 1500 BOM lines , modules and assemblies for underwater use (typically 5-30m depth), including product architecture, structural components, seals, mechanisms and mechanical interfaces.
</li><li>
Take ownership of designs end-to-end: from early concepts and CAD development → prototype builds → verification testing → design iterations → production-ready solutions.
</li><li>
Improve and refine existing prototypes by analyzing test data, identifying failure modes, and implementing robust mechanical and electro-mechanical solutions.
</li><li>
Develop designs suitable for volume production (≈1000 units/year), including materials, manufacturing methods, tolerance chains, sealing concepts, cable management, and assembly processes.
</li><li>
Collaborate closely with electronics, optics, software, and production engineers to ensure product performance, reliability, and manufacturability.
</li><li>
Support suppliers and manufacturers, review DFM input, and qualify new components and production partners.
</li><li>
Participate in testing of prototypes in our salt-water pool, in the sea close to Oslo, and in real fish-farm environments along the west coast and in Northern Norway
