Job description

Job Overview

Plan A Technologies is looking for an experienced Principal Prototyping Engineer. This role operates 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. We are looking for someone who can operate independently and is skilled across disciplines: software, hardware, AI, mechanical, and electrical. You will be taking concepts to working demos quickly and iteratively.

Some projects will involve developing new concepts from scratch. Others may focus on improving or rethinking existing technologies. You will have direct access to a prototyping budget and the freedom to move quickly without bureaucracy or layers of approval to fight through.

Please note: you must have at least 6+ years of Software and Hardware experience to be considered for this role.

JOB RESPONSIBILITY

• 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. We value prototypes over presentations.
• Operate independently. You will set your own technical direction.
• Hand off mature prototypes to the R&D engineering team in India and Australia for hardening.

Qualifications

• 6+ years of experience with Python, JavaScript, Swift, C/C++, depending on the project.
• Build hardware. PCB design, sensor integration, microcontroller programming, the works.
• CAD fluency — Sharp3D, Fusion 360, SolidWorks, or Onshape.
• Hands-on 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 things you built — GitHub, YouTube, side projects, competitive robotics, hackathons, maker projects. We care more about what you have shipped than where you went to school.
• Independence. You do not need a PM, a Jira board, or a standing meeting to make progress.
• Excellent verbal and written English communication skills
• Excellent organizational, problem-solving, and analytical abilities.
• Outstanding communication and interpersonal skills.
• Initiative and drive to do great things
