Key Responsibilities

1. SoC Hardware Architecture– Design and validate embedded hardware around Raspberry Pi / Jetson Nano or equivalent ARM SoC ecosystems; integrate cameras, thermal modules, and microfluidic actuators into compact, production-ready instrument platforms.
2. Embedded Software Stack– Develop robust firmware and application software under Linux; leverage libcamera for high-frame-rate scientific imaging pipelines; build user-facing control interfaces with Qt/C++.
3. Precision Control Systems– Implement PID or model-predictive control algorithms for high-precision temperature control (±0.001 °C) in microfluidic reaction chambers.
4. Microfluidic Integration– Collaborate with our biologists and fluidics engineers to embed droplet-generation, valving, and sensing sub-systems into the hardware architecture (preferred).
5. IP & Documentation–Draft patent application documents(provisional, PCT, and CN invention patents); maintain detailed hardware design records, BOMs, and regulatory technical files.
6. Cross-Border Collaboration– Communicate fluently in Chinese (Mandarin/Cantonese) and English during technical reviews, vendor audits, and client deployments across the Greater Bay Area.

Requirements

Must-Have

• PhD in Electronics, Computer Engineering, Automation, or related field
• Fresh grad. PhD or equivalent industrial R&D experience
• Proven ability to bring an SoC-based product from schematic to production
• Expert-level C++ (modern C++11/14/17) under embedded Linux
• Deep familiarity with libcamera/V4L2 pipelines and Qt/QMLGUI frameworks

Preferred (Highly Valued)

• Hands-on experience with microfluidic hardware (3D printing, PCB-embedded heaters, piezo actuators, etc.)
• Track record in high-precision thermal management (PCR, qPCR, or chemical synthesis platforms)
• Familiarity with ISO 13485 / IVD instrument development cycles
• Prior filing of ≥2 invention patents as principal inventor
• GPU acceleration (CUDA) on Jetson platforms for real-time image analysis

We Offer

• Competitive salary package commensurate with doctoral expertise and patent track record.
• Direct ownership of hardware architecture decisions in a flat, founder-led R&D team.
• Opportunity to build a patent portfolio in precision diagnostics and microfluidic instrumentation.
• Greater Bay Area cross-border projects with exposure to Hong Kong–Shenzhen biotech ecosystems.

How to Apply

Please submit your CV, a list of patent publications (if any), and a brief technical portfolio (GitHub/ hardware photos / Qt project demos) to admin@rafaelbiotech.com
Shortlisted candidates will be invited for a technical presentation in Shenzhen or Hong Kong within two weeks.
