Process Engineer

Job Description

Job Summary:

\n

eos partners with a network of third-party contract manufacturers (CMs) to produce personal care products at scale. The Engineering team owns the technical relationship with these CMs end-to-end — leading tech transfers, production scale-ups, and line trials from formula hand-off through first production run — while working closely with R&D, NPD, Packaging, Procurement, and Quality to keep manufacturing on spec, on time, and audit-ready. This role is the connective tissue between what eos designs and what its CMs can reliably build, evaluating new suppliers, troubleshooting existing ones, and shaping sourcing strategy along the way.

\n

This is a highly technical, hands-on individual contributor role for an experienced manufacturing engineer.

\n
• Lead tech transfers and turn-key formula hand-offs from R&D into commercial-scale production, translating lab-scale formulas into repeatable, CM-ready processes.
\n
• Own onsite scale-ups and line trials, collaborating with R&D and Packaging to bring new primary and secondary packaging components into execution at CMs.
\n
• Travel domestically 40-50% of the time to evaluate potential new CMs, troubleshoot manufacturing issues at existing suppliers, and review/approve scale-up and first production runs.
\n
• Partner on RFQs and sourcing strategy, contributing both upfront and in backend deliberations by providing insight into the capacity and capabilities eos needs from a given CM.
\n
• Collaborate cross-functionally with NPD, R&D, Packaging, and Procurement to keep new product development timelines aligned with manufacturing reality.
\n
• Work alongside the Quality team on root-cause investigations for production issues, driving corrective and preventive actions with CMs.
\n
• Challenge CM assumptions on manufacturing approach, equipment fit, and timelines, and lead difficult supplier conversations directly when needed.

\n
• Experience with capital equipment planning, equipment validations, and automation on high-volume production lines.
\n
• Working knowledge of quality systems and methodologies (e.g., APQP, CAPA) and experience partnering with supplier/manufacturing quality engineering.
\n
• Bachelor's degree in Industrial Engineering, Chemistry, Operations, or a related technical field, or equivalent hands-on manufacturing experience.
\n
• Proven track record managing onsite scale-ups and line trials, including new primary and secondary packaging introductions.
