Job description

Seeking a highly skilled and creative Mechanical Design Engineer with extensive experience in downhole tool development, particularly in the design of BHA related items including positive displacement motors, and understanding of machining/machining automation is a plus. This role will directly support our in-house downhole tool innovation group, working closely with R&D, field operations, and manufacturing to design, prototype, and iterate advanced drilling tools. Candidates must demonstrate a strong command of SolidWorks and ANSYS, a hands‑on understanding of high‑pressure mechanical systems, and an ability to collaborate on unconventional engineering challenges.

Key Responsibilities

• Able to drive/lead mechanical design of downhole drilling tools, including:
  • Creative/R&D downhole tool design and fast improvement iteration capability
  • Positive displacement / downhole drilling motors
  • BHA related tools (Jars, shock tools, etc.)
  • Through Tubing Motors
• Translate conceptual ideas into manufacturable designs using SolidWorks
• Conduct FEA analysis using ANSYS to assess tool durability, fatigue, and vibration performance in HPHT and high-torque conditions
• Iterate designs based on lab testing, field trials, and feedback from engineering and drilling teams
• Collaborate with machinists, vendors, and automation teams to ensure manufacturability and ease of maintenance
• Provide technical documentation, drawings, BOMs, and support for internal and external manufacturing
• Think creatively and strategically to address failure modes, reduce tool wear, and enhance reliability

Job Requirements

• 5+ years of mechanical engineering experience in downhole tool design
• Advanced proficiency with SolidWorks and ANSYS Mechanical/Structural
• Familiarity with material science, elastomer compatibility, and mechanical seals
• Comfortable with prototyping, design iteration, and hands‑on testing
• Strong documentation, version control, and communication skills

Ideal Candidate Traits

• Passionate about solving hard engineering problems in the energy sector
• Highly collaborative, but self‑motivated and proactive
• Comfortable working on a small, high‑performance, cross‑functional team
• Able to think outside the box and thrive in a fast‑paced innovation environment

Position will be filled at a level commensurate with experience.
