Role Overview

Are you highly resourceful, hands-on, and love bringing complex engineering concepts to life? We are looking for a versatile Lab Technician to play a crucial role in our research and development laboratory.

In this position, you won't just be sitting at a desk—you will be building, testing, and troubleshooting next-generation hardware. You will support our engineering team by maintaining a cutting-edge prototyping lab, operating 3D printers, laminating custom composite parts, and safely handling high-power electrical setups. If you are naturally handy, detail-oriented, and love a job where no two days are the same, we want to hear from you.

Core Responsibilities

  • High-Power Electronics Support: Assist engineers in assembling, wiring, and safely testing high-power electronic circuits and pulsed-power components.
  • Composite & Epoxy Fabrication: Hand-fabricate, coat, and cure specialized parts using composite materials and epoxy resins, ensuring structural and insulating integrity.
  • 3D Printing Operations: Manage our suite of 3D printers (FDM/SLA). This includes preparing CAD files, optimizing print settings, managing filament/resin stocks, and performing post-processing.
  • Lab & General Bench Work: Act as the go-to person in the lab. Modify mechanical components, build test fixtures, solder wiring harnesses, and keep the workshop organized and operating efficiently.
  • Safety & Maintenance: Ensure the lab complies with strict electrical and chemical safety protocols. Perform routine maintenance on machinery and tools.

What We Are Looking For:

  • The "Handy" Factor: A strong, proven track record of mechanical aptitude. You are comfortable using basic hand tools, power tools, workshop machinery, and precision measuring equipment.
  • Electronics Background: Basic understanding of electrical safety and components. Experience with soldering, wire crimping, and reading basic schematics is highly valued.
  • Materials Experience: Hands-on experience working with epoxies, resins, casting, or carbon fibre/fiberglass composites.
  • Digital Fabrication: Proficiency in operating and maintaining desktop 3D printers. Basic familiarity with slicing software (e.g., Bambu Studio, PrusaSlicer); basic CAD tweaking skills are a big plus.
  • Mindset: A safety-first attitude, exceptional organizational skills, and a proactive approach to solving physical, electrical and mechanical problems on the fly.

What We Offer

  • Hands-On Innovation: Work directly with cutting-edge high-power tech and advanced materials.
  • Dynamic Environment: A highly collaborative team that values practical problem-solving over rigid bureaucracy.
  • Skill Growth: Opportunities to expand your expertise in advanced manufacturing, multi-physics testing, and aerospace/defence-grade prototyping.

Due to the nature of this project, applicants must be eligible to obtain the required national security clearances.
