Process Engineering Lead​/Manager - Atlanta, GA

Nexus Circular is scaling advanced recycling technology from concept to commercial reality and preparing to license that technology globally. This role is a cornerstone position responsible for translating Nexus technology into robust, scalable, and executable process designs that deliver safe, reliable, and successful plants.

This is not a traditional plant support or EPC checker role. This is an end‑to‑end process engineering leadership role, owning the process scope from early concept through startup.

• Process engineering ownership across the full project lifecycle:
  Concept development (FEL‑0 / FEL‑1), scope definition (FEL‑2), FEED (FEL‑3), detailed design, commissioning, and startup support
• Technology scale‑up & translation:
  Work closely with technology and commercial teams to convert Nexus technology into executable process designs and licensor‑grade process packages
• Process scope definition & integrity:
  Develop and own:
  • Process design basis
  • Mass & energy balances
  • PFDs and P&IDs
  • Process simulations and operating envelopes
  • Equipment process datasheets and design criteria
• Licensing & EPC interface:
  Support development of technology packages for external customers; act as the process authority interfacing with EPC contractors and partners
• Process safety & operability:
  Lead and participate in HAZID, HAZOP, LOPA, relief system design, and operability reviews from early project stages
• Team & capability building:
  Establish process engineering workflows, standards, and best practices; mentor and grow future process engineers
• Cross‑functional collaboration:
  Work seamlessly with controls, mechanical, piping, CSA, procurement, construction, commissioning, operations, and commercial teams

• Clear, executable process scopes with minimal rework downstream
• Smooth transitions from FEL → FEED → EPC
• Strong EPC alignment and reduced technical risk
• Successful plant startups with fewer surprises
• Credible, bankable technology packages for customers

• Bachelor’s degree in Chemical Engineering
• ~10–15 years of experience in chemical, petrochemical, refining, or advanced recycling
• Demonstrated experience taking at least one technology/project from concept to startup
• Strong hands‑on capability with:
  • Aspen Plus / Aspen HYSYS (or equivalent)
  • Mass & energy balances
  • PFDs, P&IDs, equipment sizing
• Solid understanding of process safety, operability, and design standards (API, ASME, etc.)
• Comfortable working in fast‑growth, ambiguous environments
• A builder’s mindset: positive, collaborative, accountable, and ownership‑driven
• Able to communicate complex technical concepts clearly to technical and non‑technical stakeholders

• Direct impact on first‑of‑a‑kind and early‑scale plants
• Opportunity to shape how process engineering is done from the ground up
• Exposure to technology commercialization and licensing
• A seat at the table as Nexus scales globally
