Pressure Vessel Design Engineer​/Mechanical Engineer

Arc Rite Manufacturing is seeking a skilled Mechanical Engineer / Pressure Vessel Design Engineer to support the design, drafting, calculation, and fabrication of ASME code pressure vessels and oilfield production equipment.

This role is ideal for someone who can take a customer specification, field requirement, or concept and turn it into a complete fabrication‑ready drawing package with accurate calculations, material requirements, code compliance, and clear communication to the shop floor.

The ideal candidate will have strong experience with pressure vessels, separators, heater treaters, blow cases, scrubbers, production vessels, piping, skids, and fabricated oil and gas equipment.

The engineer will be responsible for:

• Creating detailed 2D and 3D drawings for pressure vessels, production equipment, piping, structural supports, and skid‑mounted packages.
• Preparing fabrication drawings, general arrangement drawings, nozzle schedules, weld details, cut sheets, BOMs, and customer approval drawings.
• Performing and reviewing pressure vessel calculations to ensure compliance with applicable ASME code requirements.
• Designing vessels in accordance with ASME Boiler and Pressure Vessel Code Section VIII, Division 1, which applies to many pressure vessels operating above 15 psig and covers design, fabrication, inspection, testing, and certification requirements.
• Supporting calculations for shell thickness, head thickness, nozzle reinforcement, MAWP, MDMT, hydrotest pressure, corrosion allowance, external pressure/vacuum, lifting lugs, saddles, supports, and wind/seismic considerations where applicable.
• Reviewing customer specifications, P&IDs, datasheets, purchase orders, and project requirements.
• Coordinating with fabrication, welding, quality control, purchasing, and sales teams to ensure the design is practical, cost‑effective, and buildable.
• Supporting ASME documentation packages, data reports, material traceability, weld maps, test requirements, and customer submittals.
• Assisting with design reviews, drawing revisions, redlines, and as‑built documentation.
• Ensuring drawings meet company standards, customer requirements, and applicable codes.
• Providing technical support to sales and operations during quoting, design clarification, and production.

The successful candidate should have experience with one or more of the following:

Preferred experience with:

• Codeware COMPRESS
  Used for ASME Section VIII pressure vessel and heat exchanger design calculations, design reports, nozzle calculations, MDMT, liquid static head, FEA‑supported design items, lift lugs, clips, cladding, fatigue screening, and related vessel design tasks.
• PV Elite by Hexagon
  Used for pressure vessel and heat exchanger design, including ASME Section VIII Division 1 and Division 2 calculations. PV Elite supports current ASME code database selections for allowable stresses and other code‑based inputs.

Acceptable related experience may include other recognized ASME pressure vessel design platforms, provided the candidate understands the underlying code calculations and does not rely solely on software output.

Preferred experience with:

• AutoCAD
• Solid Works
• Solid Edge
• CADWorx
• Navisworks

The candidate should be able to create both customer‑facing approval drawings and detailed fabrication drawings for shop use.

Experience with the following is a plus:

• Microsoft Excel for calculation sheets, BOMs, estimating support, and data tracking.
• Microsoft Word for engineering reports and submittal packages.
• ERP/MRP systems for BOM release, part numbers, and production support.
• Document control systems for drawing revisions and customer approvals.

The ideal candidate should understand or have working experience with:

• ASME Section IX welding procedure and welder qualification requirements.
• Material selection for carbon steel, stainless steel, sour service, and other customer‑specific requirements.
• Shell and head thickness calculations.
• MAWP and design pressure calculations.
• MDMT requirements.
• Hydros…
