Who are we:
Locus Fermentation Solutions is a USA-based company delivering bio-enhanced specialty chemicals at industrial scale. Through precision fermentation and integrated chemistry, we produce glycolipid biosurfactants designed to improve performance across oil and gas, mining, agriculture, and industrial applications. Our biomanufacturing platform connects strain selection, fermentation, and formulation design to create functional molecules that behave predictably in real-world systems—bridging the gap between biology and performance chemistry.
What you’ll be doing:
We are hiring a highly experienced Principal Scientist to shape scientific strategy and deliver high-impact research results across our R&D portfolio. In this role, you will independently lead complex research programs, develop advanced experimental strategies, and translate scientific insights into product and process specifications that guide scale-up and commercialization. You will leverage deep subject-matter expertise to develop innovative solutions, contribute to patents and publications, and serve as a recognized technical authority within the organization.
As a Principal Scientist, you will also mentor scientific and technical staff, collaborate with cross-functional partners, and represent the company in external scientific communities. You will play a critical role in strengthening scientific excellence, driving safety and data-integrity standards, and supporting key decisions related to product development, technology investment, and organizational capability. This is an ideal role for an accomplished scientist seeking to make a significant enterprise-level impact.
The primary focus of this role will be the development of specialty chemical reagents that enhance the efficiency and sustainability of mining operations, particularly in flotation and leaching applications.
