Process Engineer

CRA is an engineering company with over 30 years of experience delivering custom-engineered systems to the Energy and Defence sectors. We design and manufacture robust, high-performance solutions including combustion systems, biogas processing packages, gas flaring systems, thermal oxidizers, and defence-grade weapon handling equipment.
Everything we build is manufactured in-house, from mechanical fabrication to assembly and testing, enabling us to serve some of the most demanding industrial and military applications worldwide.
Our manufacturing operations span two facilities in the NCR region and are supported by in-house Design, Engineering, Quality, Procurement, Production, and Projects teams.
As we continue to scale, we are strengthening our operational leadership while implementing ERP, ISO 9001, and AS9100D systems to build a world-class manufacturing organization.

About the Role: 

We are
looking for a Process Engineer to support process engineering delivery
across CRA's product portfolio - combustion systems, biogas processing, and gas
compression. You will work under the Process Engineering Lead, producing
calculations, drawings, and documentation that feed into the design basis for
live projects. This is a hands-on, learning-intensive role suited to someone
early in their process engineering career who wants direct exposure across
multiple product lines rather than a single narrow specialisation.

Across All Product Lines

• Support the Team in
  developing design basis documents, mass and energy balances, process flow
  diagrams, and P&IDs.
  
• Perform routine process calculations under
  supervision: stoichiometry, air/fuel ratio, pressure drop, heat release,
  residence time.
  
• Prepare and maintain line lists, equipment
  lists, and process datasheets for bought-out equipment.
  
• Assist in drafting control philosophy inputs,
  operating sequences, and interlock/trip condition documentation.
  
• Coordinate with the Design/Drafting team to
  ensure P&IDs and process documents stay aligned through revisions.
  
• Participate in internal HAZOP sessions as a
  supporting team member, capturing actions and follow-ups.
  
• Support proposal preparation with preliminary
  sizing calculations and standards references.
  
• Assist with reviewing mechanical, electrical,
  and instrumentation outputs for consistency with the design basis, flagging
  discrepancies to the Team.
  

Combustion (Flares, Thermal
Oxidisers, VCUs, BMS)

• Support combustion chamber sizing
  calculations: residence time, heat intensity, temperature profile.
  
• Assist with flare radiation and stack height
  calculations under guidance (API 521 basis).
  
• Support burner selection data-gathering: fuel
  flexibility, turndown ratio requirements.
  
• Assist in compiling emission calculation
  inputs (NOx, CO, VOC destruction efficiency)
  

• Assist in biogas characterisation data review
  (CH₄/CO₂/H₂S/moisture) for incoming project inputs
  
• Support sizing calculations for gas treatment
  steps (H₂S removal, dehydration, CO₂ removal) under supervision
  
• Assist with CBG plant process documentation
  and quality-compliance checks (IS 16087 or applicable standard).
  

• Support compressor sizing calculations: flow,
  pressure ratio, stage count, intercooling, under the Lead's review.
  
• Assist in preparing skid process
  documentation: scrubbers, separators, coolers, control valves, relief devices.
  
• Prepare process datasheets for bought-out
  equipment (compressors, heat exchangers, vessels) for Lead review.
  

Requirements

• Degree in Chemical Engineering or Mechanical
  Engineering.
  
• 1-3 years of process engineering experience in
  equipment design, EPC, ;internship/project experience
  producing process calculations or documentation is acceptable for candidates at the lower end of this range.
  
• Basic working knowledge of process engineering
  fundamentals: mass/energy balances, fluid flow, heat transfer.
  
• Comfortable working with P&IDs and process
  flow diagrams, and willing to learn plant-specific conventions.
  
• Strong numerical and analytical skills;
  comfortable with detailed calculations and documentation.
  
• Eagerness to learn across multiple product
  lines (combustion, biogas, gas compression) rather than a single narrow
  specialisation.
  

• Exposure to combustion or gas processing
  coursework, projects, or internships.
  
• Familiarity with process simulation tools
  (Aspen HYSYS, ProMax, or similar) at an academic or working level.
  
• Basic awareness of relevant standards: API
  521, NFPA 86 or EN 746, ASME/IS codes for pressure equipment.
  
• Prior exposure to an equipment OEM or
  manufacturing environment.
