Process Engineering Lead - 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 endtoend 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 (FEL0 / FEL1), scope definition (FEL2), FEED (FEL3), detailed design, commissioning, and startup support

* Technology scaleup & translation
Work closely with technology and commercial teams to convert Nexus technology into executable process designs and licensorgrade process packages

* Process scope definition & integrity
Develop and own:
o Process design basis
o Mass & energy balances
o PFDs and P&IDs
o Process simulations and operating envelopes
o 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 handson capability with:
o Aspen Plus / Aspen HYSYS (or equivalent)
o Mass & energy balances
o PFDs, P&IDs, equipment sizing

* Solid understanding of process safety, operability, and design standards (API, ASME, etc.)

* Comfortable working in fastgrowth, ambiguous environments

* A builder's mindset: positive, collaborative, accountable, and ownership driven

* Able to communicate complex technical concepts clearly to technical and nontechnical stakeholders
Why Nexus

* Direct impact on firstofakind and earlyscale 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
