Rotating Machine Lead Engineer

What we do at Blykalla

Blykalla is a Swedish deep-tech company at the forefront of the nuclear industry, pioneering the development of small modular reactors that provide clean, safe, and reliable energy. Thanks to lead-cooling, we achieve high safety in a very compact format, allowing for a simple and cost-effective design that can be mass-produced. Our unique reactor design will provide safe and green baseload energy that perfectly complements solar and wind power.

What you’ll get to do

As a Rotating Machine Lead Engineer, you will own the rotating equipment portfolio of the SEALER plant — from the Primary Coolant Pumps (PCPs) submerged in molten lead above 400 °C, where conventional bearing and sealing solutions don't apply, to the secondary-side feedwater and condensate pumps and the full set of auxiliary and safety-related pumps the plant requires. It is a technically demanding portfolio that spans genuinely novel engineering on the primary side and rigorous nuclear-grade discipline throughout:

Define functional and design requirements for the full rotating equipment portfolio — PCPs in molten lead, secondary-side feedwater and condensate pumps, and all auxiliary, safety-related, and service pumps.

Develop design basis documentation and lead trade-off studies on pump configuration, drive arrangement, sealing strategy, and bearing technology.

Set priorities across the portfolio — distinguishing where Blykalla-specific engineering is warranted from where standard industrial solutions suffice.

Act as Blykalla's technical counterpart to pump suppliers and engineering partners, challenging design choices and steering solutions to fit plant requirements across hydraulics, sealing, materials, and maintainability.

Define the scope of hydraulic, rotordynamic, and structural analyses; brief specialists; and critically review their outputs. Use hand calculations to sanity-check results.

Own supplier work packages: evaluate proposals, lead design reviews, and keep pump d
