Plantible is developing the next generation of our commercial production facilities. The Upstream Project Engineer will own the engineering and field execution of the systems that grow, cultivate, harvest, and deliver Lemna biomass to downstream processing.

You will sit between Plantible's agricultural and process experts and the people designing, supplying, and building our facilities. Your scope includes greenhouse structures, cultivation systems, water and nutrient delivery, harvest systems, biomass handling, and the utilities and infrastructure that support them.

This role is both technical and field based. Your job is to turn upstream requirements into systems we can procure, build repeatedly, commission, and operate at scale.

• Translate requirements from Plantible's Engineering, R&D, Operations, Maintenance, and Food Safety teams into clear scopes and deliverables for external engineering partners and vendors.
• Coordinate the disciplines required for your systems, including process, mechanical, piping, civil, structural, electrical, controls, utilities, and facility infrastructure.
• Understand where systems interface, make sure every interface has an owner, and drive technical decisions to closure.
• Maintain engineering deliverables, decisions, dependencies, risks, and open items against the overall project schedule.
• Surface gaps early. 'Waiting on Engineering' is not a project plan.

• Support FEL, conceptual design, FEED, and detailed engineering for assigned systems and project packages.
• Coordinate development and review of Basis of Design documents, equipment lists, utility requirements, layouts, specifications, drawings, and other core project deliverables.
• Lead design reviews with Plantible subject-matter experts, Operations, and external engineers.
• Challenge designs for safety, constructability, operability, maintainability, hygienic design, cost, and unnecessary complexity.
• Translate lessons from Ranchito into engineering standards and repeatable design packages for future Plantible facilities.

• Develop technical scopes and bid packages for equipment, materials, and engineered systems.
• Coordinate RFQs, technical evaluations, bid leveling, vendor selection, and technical alignment before purchase.
• Manage vendor drawings, calculations, data, documentation, and interfaces with the broader facility design.
• Track major equipment and materials from specification through fabrication, FAT, delivery, installation, and startup.
• Understand which decisions and long-lead packages are driving the project schedule and act before they become constraints.

• Serve as Plantible's engineering point of contact during construction for assigned systems and scopes.
• Coordinate RFIs, submittals, design clarifications, field changes, and vendor questions.
• Maintain a strong onsite presence during active installation: walk the work, verify progress, identify constraints, and drive…
