Senior Process Controls Engineer

Manus works across industries and value chains to accelerate the transition to BioAlternatives better performing and more sustainable versions of complex molecules traditionally sourced from plants, animals, or fossil fuels. Our platform is proven to work across scales, bridging the Valley of Death between lab and manufacturing more efficiently and more reliably to deliver the benefits of synthetic biology today.


The Senior Process Controls Engineer position is a hands-on control engineering position. Candidates must demonstrate experience in programming, configuring, implementing, commissioning, and troubleshooting Emerson DeltaV DCS applications. Strong Allen-Bradley PLC knowledge and experience integrating PLC-based equipment with DeltaV are also highly valued. Project-management experience is a plus but is not a mandatory qualification
