Job Title

Company Description Mercle is building the foundational layer of trust for the digital age with our innovative proof-of-personhood solution. In an increasingly AI-dominated online landscape, verifying unique human identity is paramount. Our hybrid system tackles this challenge head-on by combiningFacial Scanswith 3D liveness detection,Social Vouchesthrough a decentralized web-of-trust,Behavioral Signalsto differentiate human traits from AI mimicry, and the secure, privacy-compliant integration ofExisting IDsas a supplementary tier. This modular architecture delivers over 99.9% overall accuracy, ensures privacy via zero-knowledge proofs, and offers global scalability at costs under $0.10 per verification, empowering individuals with control over their digital identity and fostering a more trustworthy online ecosystem.Role Description As our Hardware & Electronics Engineer, you will lead end‑to‑end design and development of the core electronics for Mercle’s biometric scanner. You’ll translate system requirements into robust PCB designs, select and integrate sensors and power components, and collaborate closely with mechanical, firmware, and CV engineers to deliver a production‑ready prototype.Qualifications Expertise in Hardware Development and Hardware Engineering Proficiency in Circuit Design and Electronics Hardware Design Strong understanding of Computer Hardware Excellent problem-solving and analytical skills Ability to work independently and collaborate with remote teams Bachelor's degree in Electrical Engineering, Computer Engineering, or related field Experience in the technology or electronics industry is a plusKey Responsibilities Electronic System Architecture Define block‑level schematics covering power distribution, sensor interfaces (RGB & depth cameras), lighting control, and communications (USB, Ethernet, Wi‑Fi). Collaborate on system‑level trade‑offs: cost, size, thermal budget, and EMI/EMC compliance. PCB Design & Layout Create multi‑layer PCB designs using Altium or KiCad, ensuring signal integrity for high‑speed camera interfaces and power rails. Route differential pairs (e.g., MIPI CSI), manage ground planes, and implement design‑for‑manufacturability (DFM) best practices. Component Selection & Procurement Choose sensors, power regulators, connectors, and other BOM items based on performance, availability, and cost targets. Work with vendors to source components, evaluate samples, and mitigate supply‑chain risks. Prototype Assembly & Testing Oversee board fabrication, assembly, and bring‑up on development kits (e.g., NVIDIA Jetson Dev Kit). Develop test fixtures and harnesses to validate signal integrity, power sequencing, and peripheral communications. Cross‑Functional Collaboration Partner with Mechanical Engineers on enclosure interfaces (connector cutouts, thermal paths). Coordinate with Firmware Engineers to define device‑tree entries, power sequencing, and over‑the‑air update mechanisms. Support Computer Vision team by ensuring clean camera power and clocking for reliable image capture. Regulatory & Documentation Draft and maintain hardware design documentation: schematics, PCB fabrication drawings, assembly manuals, and test procedures. Prepare for EMC/EMI testing and safety certifications (CE, FCC), engaging external labs as needed.Required Qualifications Bachelor’s or Master’s degree in Electrical/Electronics Engineering or equivalent. 3+ years of hands‑on experience designing complex PCBs, including high‑speed interfaces (MIPI, LVDS) and mixed‑signal circuits. Proficiency with Altium Designer, KiCad, or similar EDA tools. Strong understanding of power electronics: DC‑DC converters, LDOs, power sequencing, and thermal management. Experience with camera modules or sensor integration on embedded platforms (Jetson, Raspberry Pi, etc.). Familiarity with EMC/EMI principles and design techniques for compliance. Excellent debugging skills using oscilloscopes, logic analyzers, and power analyzers.Preferred Skills Prior work on consumer‑grade hardware prototypes or small‑batch production runs. Knowledge of One‑Way Mirror designs or matrix/LED display interfacing. Experience with camera driver configuration in Linux Device Tree. Exposure to hardware security best practices (secure boot, hardware root of trust). Familiarity with biometric sensor standards or previous work on liveness‑detectionWhat we offer A key role in building the world’s first global proof‑of‑personhood network. A collaborative, mission‑driven environment with a lean, agile team. Flexible remote work, regular syncs in Asia‑Bangkok timezone. Competitive salary, equity, and token incentives. Opportunities for professional growth across hardware, firmware, and product domains.
