Company

hirify.global is a frontier research lab developing high-bandwidth brain-computer interfaces that integrate with advanced artificial intelligence.

What you will do

• Own the mechanical architecture and packaging of high-density PCBAs, sensors, mixed-signal components, cables, thermal interfaces, and user-facing structures.
• Rapidly prototype and validate hardware using 3D printing, CNC, sheet metal, soft goods, and quick-turn tooling.
• Model and validate thermal performance in compact electronic systems with strict temperature and form-factor constraints.
• Design fixtures, jigs, mounts, sample holders, alignment and calibration mechanisms, environmental interfaces, and test stands for scientific workflows.
• Define and validate quantitative criteria for tolerance, accuracy, repeatability, drift, calibration, environmental stability, and measurement uncertainty.
• Lead prototype-to-production transitions, vendor relationships, tooling, inspection criteria, yield, reliability, and mechanical testing.

Requirements

• Deep experience designing complex mechanical hardware through build, testing, failure analysis, and multiple product iterations.
• Strong fundamentals in tolerance analysis, materials and process selection, thermal design, mechanical architecture, and design verification.
• Experience delivering manufacturable designs and working with vendors through tooling, production release, and yield or reliability issues.
• Experience with rapid prototyping and with designing instrumentation or tooling that enables repeatable, documented workflows.
• Analytical problem-solving skills and a systems mindset focused on calibration, error budgets, ergonomics, documentation, and reproducibility.
• Ability to collaborate with Electrical Engineering, Software/Platform, Industrial Design, Clinical, and scientific teams.

Nice to have

• Experience with scientific instrumentation, precision motion or alignment, medical devices, implantables, lab automation, or lightweight test automation and data analysis.

Culture & Benefits

• Work in a frontier research environment focused on bridging biological and artificial intelligence.
• Build technology across electrical, mechanical, materials, systems, and engineering physics disciplines.
• Use tight prototype, test, and iteration cycles to accelerate scientific development.
• Equity is included in the compensation package.
• Employment is full time.
