Invest in your career with a Madrona-funded company.

At Nautilus, we have a big and important mission: improve the health of millions by unleashing the potential of the proteome to accelerate drug development and enable a new world of precision and personalized medicine. We are developing a single-molecule protein analysis platform of unprecedented sensitivity, scale, and ease of use that we believe will democratize access to the proteome — one of the most dynamic and valuable sources of biological insight. To accomplish this, we are pursuing deep, hard science with an entrepreneurial mindset and creating a world-class team of builders, innovators, and dreamers across a wide range of disciplines.

We are seeking a Manufacturing Finance & Inventory Operations Manager to serve as the bridge between operations and finance at Nautilus. This role will own the integrity of inventory transactions, operational financial controls, standard costing methodologies, and manufacturing variance analysis for our reagent, flow cell, and instrumentation product lines. You will work cross-functionally with operations, supply chain, procurement, and leadership to ensure our NetSuite ERP and inventory systems accurately reflect the economics of the business.

This is a highly hands-on role, ideal for someone who has operated in biotech, life sciences, medical device, or other regulated manufacturing environments where inventory and operational accounting are deeply intertwined. You will play a critical role in enabling scalable financial reporting, accurate gross margins, inventory visibility, and operational decision-making as Nautilus moves from pre-commercial to commercial stage.

This position will report to the Corporate Controller.
