About the Position

Niron is seeking a Principal Compaction Engineer for its Pilot Production facility, located in Minneapolis, MN. This individual will be involved in many aspects of machining Niron's magnets.

The Principal Compaction Engineer will be responsible for advancing the methods and efficiency of the FeN permanent magnet compaction processes in both Pilot and full-scale Production, including the identification of best equipment, processes, tooling (including coatings), fixturing and work holding, and coolants. You will work closely with the Machinist and the Finishing engineering teams to design trials, process materials, and characterize the resulting magnets.

Interpretation of the results will culminate in a proposal to further improve the quality and efficiency of the machining processes. The role will include hands-on processing of materials and fixturing. You will be responsible for transferring developed processes into production including process documentation and training of Machinists.

Niron is a fast-paced environment requiring a very collaborative approach to work. A team-based mentality and agility is important.
