• Apply GD&T principles to communicate critical tolerances fits datums surface finishes and inspection requirements.
• Support tolerance stack-up reviews for critical pump assemblies and highly loaded components.
• Create and maintain bills of material for pump assemblies subassemblies and serviceable components.
• Support new product development prototype builds design iterations and production release packages.
• Update existing pump drawings and models to improve manufacturability reduce cost reduce weight improve reliability and simplify assembly or field service.
• Work with engineers to evaluate design tradeoffs related to pressure rating flow rate fatigue life sealing performance bearing loads fastener selection and service intervals.
• Collaborate with NOV manufacturing facilities and suppliers to ensure designs can be machined fabricated inspected assembled and serviced efficiently.
• Support design standardization across pump product lines including common components drawing practices materials fasteners and modeling methods.
• Review as-built feedback field issues manufacturing concerns and service observations to support continuous product improvement.
• Assist with engineering change requests drawing revisions and controlled product release documentation.
• Maintain organized 3D models assembly trees configurations part numbers revisions and drawing files.

• Packing sealing valve and seat arrangements
• Manifolds suction/discharge connections and pressure-containing components
• Service tooling lifting fixtures and assembly aids
• Field retrofit kits and production improvement packages

Required Education Skills and Experience

• High School Diploma or Equivalent and 2-4 years of related experience.
• Proficiency with SolidWorks PDM for 3D modeling assemblies configurations and detailed drawings.
• Proficiency with AutoCAD or similar 2D drafting software.
• Experience creating drawings for machined components with tight tolerances and critical fits.
• Strong understanding of mechanical drafting GD&T tolerance stack-up datums surface finish and inspection requirements.
• Ability to design and document parts for CNC machining fabrication welding coatings and assembly.
• Understanding of materials used in highly loaded mechanical components pressure-containing parts and wear components.
• Ability to create accurate BOMs and clearly define part hierarchy.
• Strong attention to detail and commitment to high-quality drawing releases.
• Ability to work in a fast-moving R&D environment with changing priorities and evolving design requirements.
• Practical understanding of manufacturability assembly inspection cost reduction and field serviceability.
• Strong communication skills and ability to work closely with engineering production suppliers and service teams.

• Familiarity with oilfield pressure pumping hydraulic fracturing cementing coiled tubing drilling or industrial pumping applications.
• Knowledge of pressure-containing component design and documentation.
• Familiarity with applicable ASME API ASTM and ISO standards related to pump design materials tolerancing and manufacturing.
• Experience with high-strength steels stainless steels forgings castings heat treatment coatings and wear-resistant materials.
• Understanding of pump failure modes such as fatigue washout erosion cavitation seal wear bearing failure fretting galling and fastener loosening.
• Familiarity with engineering change processes revision control product lifecycle management and manufacturing release workflows.
• Experience designing for global manufacturing and multi-site production.

Value to the Team

This role will provide dedicated design expertise for positive displacement pump development and improvement. A strong pump designer will help improve drawing quality accelerate design iterations support engineers during field or test activities and create consistent design documentation across pump products.

By working directly with engineering and manufacturing teams the designer will help ensure pump components are designed not only for performance but also for machinability assembly inspection serviceability and cost-effective production. This role will free engineers to focus on system-level design analysis testing and new product development while maintaining strong execution discipline in models drawings and release packages.

Ideal Candidate Profile

The ideal candidate is a mechanically minded designer who understands that pump performance depends on details: tolerances fits materials surface finishes assembly sequence sealing interfaces and service access.

This person should be comfortable working from early concepts sketches legacy drawings field feedback and engineering direction. They should be able to convert ideas into professional design packages that manufacturing teams can build and service teams can support.

The strongest candidate will bring both design software skill and practical product judgment someone who can make a part look right on the screen but also understands how it will be machined assembled loaded repaired and used in the field.
