Principal Prototyping Engineer

About the role

Plan A Technologies is seeking an experienced Principal Prototyping Engineer to operate outside the traditional delivery engineering structure. You will report directly to the CEO and collaborate with leadership and engineering teams to rapidly turn ideas into working prototypes. This role requires independence and cross-disciplinary skills in software, hardware, AI, mechanical, and electrical engineering. You will take concepts to working demos quickly and iteratively, with direct access to a prototyping budget and the freedom to move without bureaucracy.

Responsibilities

• Build working prototypes of new casino gaming products: hardware, software, AI, or all three.
• Translate high-level ideas into working code and physical builds quickly.
• Integrate sensors, RFID, cameras, displays, and embedded systems into functional MVPs.
• Use AI tooling and automation to compress development timelines.
• Stand up demos weekly, prioritizing prototypes over presentations.
• Operate independently, setting your own technical direction.
• Hand off mature prototypes to the R&D engineering team in India and Australia for hardening.

Requirements

• 6+ years of experience with Python, JavaScript, Swift, or C/C++, depending on the project.
• Hands-on hardware experience: PCB design, sensor integration, and microcontroller programming.
• CAD fluency (Sharp3D, Fusion 360, SolidWorks, or Onshape).
• Experience with 3D printers, CNC, laser cutters, and other rapid prototyping equipment.
• Comfortable with Raspberry Pi, Arduino, Jetson, ESP32, Android, and similar platforms.
• Working knowledge of modern AI tooling (LLMs, computer vision, agents, automation).
• Integration experience with APIs, RFID, cameras, sensors, and displays.
• A portfolio of shipped projects (GitHub, YouTube, side projects, competitive robotics, hackathons, or maker projects).
• Ability to work independently without needing a PM, Jira board, or standing meetings.
• Excellent verbal and written English communication skills.
• Strong organizational, problem-solving, and analytical abilities.
• Initiative and drive to deliver impactful results.
