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. What you will Own 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 What Success looks Like 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 What we are looking for 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 Why Nexus 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 Note: The above statements are intended to describe the general nature and level of work being performed by the incumbent.
