Job summary

CRA is seeking a Process Engineer to support process engineering delivery across combustion, biogas, and gas compression products. You will work under the Process Engineering Lead, producing calculations and documentation that feed the design basis for live projects.

This is a hands-on, learning-intensive role suited to someone early in their process engineering career with exposure to multiple product lines.

Qualifications

• Proficiency in mass/energy balances and process fundamentals.
• Comfort with P&IDs and process flow diagrams; learn plant conventions.
• Strong numerical and analytical skills; capable of detailed calculations and documentation.

Responsibilities

• Develop design basis documents, mass and energy balances, P&IDs.
• Perform routine process calculations under supervision (stoichiometry, air/fuel ratio, pressure drop).
• Prepare line lists, equipment lists, and datasheets for bought‑out equipment.
• Assist in drafting control philosophy inputs, operating sequences, and interlock/trip documentation.
• Coordinate with Design/Drafting to keep P&IDs aligned through revisions.
• Participate in internal HAZOP sessions as a supporting team member.
• Support proposal sizing calculations and standards references.
• Review outputs for consistency with the design basis and flag discrepancies.

Job description

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)

Biogas Processing & Upgrading

• 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).

Gas Compression & Processing Skids

• 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.

Preferred

• 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.

Benefits

• Learning & development support — standards training, certifications, mentorship
• Cross-product-line exposure (combustion, biogas, gas compression) as a genuine perk, not just a job requirement
• Performance-linked appraisal and Incentives.
• Site exposure opportunities as experience grows
• Health insurance covering immediate family, not just the employee
• Paid annual/sick leave and public holidays
