Job Description

Role Snapshot

You’ll own the pulse power system that comprises the drill bit, advancing prototypes into reliable, field-ready hardware in a harsh downhole environment. You’ll push electric insulation and field control to the edge of what’s possible, balancing physics, manufacturability, and safety. You’ll turn a working test environment into a repeatable build, test, and learn loop, making smart component-level decisions when the perfect part does not exist

Key Responsibilities

  • Architect and build the pulse power source from component level, selecting, qualifying, and validating parts under real tool constraints
  • Drive electric insulation strategy, using field stress analysis and experiments to define materials, geometries, and interfaces for high reliability
  • Execute pulse power circuit layout and packaging, optimizing creepage, clearance, partial discharge margins, and thermal paths
  • Lead component testing and failure analysis, closing the loop between simulation, bench results, and design updates
  • Translate system requirements into supplier-ready specifications, negotiate tradeoffs, and interpret supplier test data to make pragmatic choices
  • Own the prototype test environment, expand test coverage, and define acceptance criteria tied to field conditions and safety

What You Bring

Technical Toolkit

  • High voltage pulse systems, insulation systems, dielectric materials, potting and encapsulation
  • Field simulation and circuit modeling, FEM tools, SPICE
  • Pulse topologies, capacitors, pulse transformers, resistive dividers, snubbers
  • HV PCB layout, creepage and clearance, corona and partial discharge testing
  • Test methods, high voltage safety, instrumentation, data acquisition

Professional Experience

  • Design, build, and iterate at the component and subsystem level, not just simulate
  • Analyze electric field stress and convert insights into geometry, materials, and interfaces
  • Communicate with suppliers, translate GA specs, and qualify parts against system behavior
  • Operate safely in 40 kV DC input regimes with modest installed power around 40 kW

Nice-to-have

  • Downhole or harsh-environment packaging experience, oil and gas tools
  • Experience balancing nonstandard pulse requirements beyond textbook Marx designs
  • Bilingual collaboration across engineering and manufacturing
