About Immensa
Immensa is transforming how the world's largest energy companies address critical spare part challenges. Our solutions help asset-intensive organisations decrease over-stocking, reduce downtime, manage obsolescence, and strengthen supply chain resilience through advanced digital inventory and distributed manufacturing technologies.
We partner with some of the world's largest Oil & Gas and industrial companies, supporting mission-critical operations where reliability, quality, and trust are essential.
Role Overview
We are seeking a Manufacturing Engineer – Subject Matter Expert (Static Equipment), reporting to the Head of Project Management. This is an individual contributor role with matrix accountability for assigned project teams and supplier deliverables.
- To act as the technical subject-matter expert for static equipment — valves, pressure vessels, heat exchangers, columns, tanks, skids and associated piping — across assigned manufacturing projects, interpreting 3D models and 2D engineering drawings to define, plan and drive execution.
- To own the manufacturing project lifecycle for static equipment component scopes, from kick-off through supplier delivery and final inspection, ensuring On-Time-In-Full (OTIF) delivery against customer requirements.
- To be the primary technical and commercial interface between Immensa and its static equipment and fabrication supply base, translating design intent into a manufacturable, code-compliant and quality-assured production route.
Main Responsibilities
- Read, interpret and validate 3D CAD models and 2D engineering drawings — including GD&T, datums, tolerances, weld symbols and joint details, corrosion allowance, material and NDT callouts — for pressure-retaining and fabricated static equipment.
- Select and justify the optimum manufacturing route (plate cutting and rolling, forming and pressing, shell and head fabrication, nozzle and flange preparation, tube-to-tubesheet welding and expansion, cladding and weld overlay, machining of sealing faces, post-weld heat treatment) and material of construction for the service conditions.
- Address fabrication specifics — weld procedure and welder qualification (WPS/PQR/WPQ), welding sequence and distortion control, fit-up and alignment tolerances, out-of-roundness, PWHT cycles and pressure-test requirements.
- Develop and manage project schedules, milestones and deliverables for assigned static equipment orders, tracking live status against OTIF targets.
- Drive supplier execution — issue technical data packages, review fabrication and welding process plans, weld maps and manufacturing record books, and close out technical queries.
- Lead design and process reviews; identify barriers early and apply sound engineering judgement to provide practical solutions.
- Own risk identification and mitigation across technical feasibility, quality, cost and delivery; maintain project risk and lessons-learned registers.
- Manage stakeholders across sales, DFAM/design, quality, production and the customer, providing clear status reporting and timely escalation.
- Review inspection and test data (dimensional, radiography, UT, MPI/DPI, PMI and hardness, hydrostatic and pneumatic test records, material certificates) and disposition non-conformances with the responsible design engineer.
- Support Quality in preparing Inspection & Test Plans (ITPs), coordinate third-party and authorised-inspector involvement, and ensure supplier compliance to ASME, API, ASTM and customer specifications.
- Support estimation and tendering by defining the manufacturing journey, fabrication, welding, NDT and testing costing inputs and realistic lead times for static equipment scopes.
- Coordinate reverse-engineering and spare-parts projects for legacy static equipment and internals, justifying OEM design and material adaptations where required to achieve manufacturability and code compliance.
Scope of Authority
Works closely with sales, DFAM/design, quality, production and external suppliers. Authorised to direct supplier technical execution and disposition assigned project deliverables within the project management framework.
Accountabilities
- Strict adherence to the Company's Policies & Procedures.
- Operate strictly within the Company ISO framework.
- Delivery of assigned projects to OTIF, quality and cost targets as per set KPIs.
Qualifications and Skills Required
- Degree in Mechanical, Manufacturing or Welding Engineering (minimum Bachelor's).
- Minimum 5–6 years experience in static equipment fabrication within oil & gas, energy or heavy engineering, ideally gained with a pressure-vessel or heat-exchanger fabricator.
- Deep subject-matter expertise in the design intent and fabrication of pressure vessels, shell-and-tube and air-cooled heat exchangers, columns, storage tanks and piping — including welding processes, weldability of carbon, low-alloy, stainless and clad materials, heat treatment and associated NDT methods.
- Proven ability to read and interpret 3D models and 2D engineering drawings, including full GD&T and welding callouts.
- Strong familiarity with ASME VIII Div. 1 and Div. 2, ASME IX and B31.3, TEMA, API (including 650, 660, 661 and 510), ASTM and equivalent standards for materials and applications.
- Welding or inspection certification (CSWIP, AWS CWI, IWE/IWT or equivalent) is an advantage.
- Demonstrated project-management capability — planning, scheduling, risk mitigation and stakeholder management.
- Excellent communicator; tailors technical messaging to internal teams, external customers and suppliers.
- Knowledgeable in reverse engineering, spare-parts production, inspection and testing.
- Exceptional attention to detail and accuracy under pressure, with a strong sense of urgency and ownership.
- Self-motivated team player, effective both independently and across multiple locations and time zones.
