Flexible ways of working
Flexible hours and delivery-led collaboration — trust professional judgment over clock-watching. We staff by merit and focus people on work that matters.

Based at Hong Kong Science Park, Hitrons combines semiconductor engineering depth with the DR H wearable brand to make AI + Health wearable every day. We are looking for people who care about craft, own outcomes, and collaborate across disciplines.
We respect talent, recruit for character and craft, and invest in development. We hire on merit, give every role clear growth paths and project visibility — so your expertise is seen and your career has direction.

Engineering, design, brand and operations share one table with fewer layers — reviews respect each discipline and solve problems early.

Hong Kong Science Park and Shenzhen R&D teams work in modern offices and labs that support deep work, rapid prototyping and wearable validation.
You finish within constraints — power, size, comfort, data stability — instead of stacking feature lists.
You join reviews, read adjacent disciplines' work, and unblock progress instead of waiting in a silo.
You align with Alan Chan's East-meets-West design philosophy — quiet, trustworthy, durable health tech without gimmick UX.
These roles are open ongoing or as projects start. Send your CV and portfolio; if there is no immediate match, we keep strong profiles on file.
Bluetooth stacks, sensor drivers and low-power firmware for rings and glasses at production scale.
Miniature PCBA schematics, power and sensing chains, EMC and DFM for wearable form factors.
Health data cloud, device connectivity and APIs for app and algorithm pipelines with privacy and reliability.
Ring/glasses structures, ergonomics, sealing and reliability through molding, metal and CNC.
Health time-series models, on-device inference and app data pipelines for readable insights.
iOS/Android health apps, device onboarding and data visualization with firmware and algorithms.
DR H wearable definition, roadmap and cross-team delivery across hardware and software.
CMF, identity and editorial craft under DR H's East-meets-West design aesthetic.
Health app and on-device UX, information architecture and visual design aligned with DR H brand and readable insights.
EVT/DVT plans, sensor calibration and reliability testing through to production yield.
