In this full-time role, you’ll play a critical part in developing early-phase process designs, managing engineering deliverables across project phases, and ensuring alignment with our technical, commercial, and sustainability goals. You’ll collaborate with design contractors, vendors, and procurement teams, and support commissioning efforts as needed.

What You'll Do

• Develop Concept Designs and Feasibility Studies, including engineering scope of work, timelines, resource planning, and cost estimates for project evaluation.
• Manage and interface with Engineering Consultants and Design Contractors through Concept, FEED, and Detailed Design phases to ensure quality and technical alignment.
• Develop and review core process engineering deliverables, including:
  • Process Flow Diagrams (PFDs)
  • Piping & Instrumentation Diagrams (P&IDs)
  • Heat & Material Balances (H&MB)
  • Equipment and Line Sizing
  • Process Datasheets
  • Utility Flow Schemes
• Perform process simulations using Aspen HYSYS, Aspen Plus, or other tools to validate and optimize designs.
• Lead and participate in technical workshops such as HAZOP, HAZID, SIL, and Design Reviews to ensure thorough risk and design assurance.
• Engage with vendors and support procurement processes, including preparation of technical specifications, bid evaluations, and clarifications.
• Contribute to process improvement and optimization initiatives, working cross-functionally to drive integration, performance, and operability.
• Promote energy efficiency and carbon footprint reduction through innovative and practical design practices.
• Stay informed on industry trends and technologies, particularly those related to carbon capture, utilization, and mineralization.

Who You Are

Essential:

• Bachelor’s or master’s degree in Chemical or Process Engineering.
• 5-8 years of relevant process engineering experience, with significant exposure to Concept, Pre-FEED, and FEED phases.
• Proficiency in process simulation tools such as Aspen HYSYS or Aspen Plus.
• Solid grasp of early-stage project development and ability to translate high-level concepts into executable designs.
• Strong knowledge of international engineering standards (API, ASME, IEC).
• Proven ability to manage and review work from contractors, consultants, and vendors.
• Strong communication and analytical skills to synthesize data and support decision-making.
• Experience supporting cost estimation, scheduling, and value-engineered design development.

Bonus:

• Experience with CO₂capture, utilization, storage (CCUS), or mineralization systems.
• Familiarity with modular design, remote operations, or digital twin technologies.
• Experience working in a startup or fast-paced clean-tech environment.
