Job summary

Ultrahuman is seeking a Hardware Design Engineer to own electronics for our next-generation wearables, including the ring family. You will drive architecture, PCB layout, bring-up, and mass production, working with mechanical, firmware, and manufacturing teams on rapid product cycles.

You will design HDI PCBs, 2.4 GHz BLE antennas, NFC coils, and power architectures to meet multi-day battery life in a compact form factor, while ensuring reliability and compliance.

Qualifications

• Bachelor's or Master's in EEE, Electronics, or equivalent practical experience.
• 4+ years hands-on hardware/PCB design in consumer electronics or wearables.
• Proficiency with OrCAD / Allegro schematic and PCB tools.
• Proven track record taking a product from schematic through layout to volume production.
• Knowledge of power electronics and active/passive component selection.
• Familiarity with FCC, CE, BIS, RoHS and IEC PCB safety standards.

Responsibilities

• Translate product requirements into hardware architecture, then into schematics and manufacturable PCB designs using OrCAD / Allegro (Cadence).
• Own component selection across MCU/SoC, PMIC, sensor AFEs, and RF front-ends.
• Design high-density (HDI), rigid, and rigid-flex PCB layouts for space-constrained wearables.
• Design 2.4 GHz BLE antennas and NFC coils, matching networks, and controlled-impedance routing.
• Apply signal-integrity best practices for high-speed interfaces and mixed-signal boards.
• Own Gerber/ODB++ release, BOMs, panelization, and manufacturing data packages.
• Drive DFM/DFA reviews with fab/EMS partners; support NPI through EVT/DVT/PVT to mass production.
• Coordinate with test engineers on board bring-up and RF validation.

ULTRAHUMAN HARDWARE

Hardware Design Engineer Wearables

Bangalore (Kudlu Gate)| On-site | Full-time |

Salary: 30L-45L + ESOPs

ABOUT THE ROLE

Ultrahuman's Hardware division builds award-winning wearables — the Ultrahuman Ring and Ring Air — pushing consumer technology in health and metabolic fitness. We're looking for a Hardware Design Engineer to own electronics design for our next-generation smart rings, from architecture and schematic capture through PCB layout, bring-up, and mass production.

This is a hands-on role at the extremes of miniaturization and power efficiency. You'll make architecture-level component decisions, drive high-density and RF layout, and take designs through NPI to volume — working closely with mechanical, firmware, and manufacturing teams on fast product cycles.

KEY RESPONSIBILITIES

Architecture & Schematic Design

• Translate product requirements into hardware architecture, then into schematics and manufacturable PCB designs using OrCAD / Allegro (Cadence).
• Own component selection across MCU/SoC, PMIC, sensor AFEs, and RF front-ends — balancing size, power, cost, and supply availability.
• Handle schematic-to-layout conversion and netlist import; create and maintain symbol/footprint libraries and land patterns.

High-Density & RF Layout

• Design and review high-density (HDI), rigid, and rigid-flex PCB layouts for space-constrained wearable form factors.
• Design 2.4 GHz BLE antennas and NFC coils, matching networks, and controlled-impedance routing; support antenna tuning and RF validation.
• Apply signal-integrity best practices for high-speed digital interfaces and mixed-signal boards.

Power & Low-Power Design

• Architect power trees around PMICs, buck/boost converters, and LDOs, including Li-ion charging for small-capacity cells.
• Build and validate ultra-low-power current budgets to meet multi-day battery-life targets.
• Strong grasp of power electronics and active/passive component behaviour.

Sensor Integration

• Integrate optical biosensing (PPG) AFEs, IMUs, temperature sensors, and haptics; own IC/SPI interface design and analog front-end layout.

Manufacturing & DFM

• Own Gerber/ODB++ release, fabrication and assembly drawings, panelization, and full manufacturing data packages.
• Prepare and maintain BOMs; evaluate and qualify alternate / second-source components.
• Drive DFM/DFA reviews with fab and SMT/EMS partners; support NPI through EVT/DVT/PVT to mass production.
• Sound understanding of PCB materials, stackups, and component assembly processes.

Compliance, Reliability & Validation

• Apply EMI/EMC, thermal, and mechanical design best practices.
• Support pre-compliance and certification across FCC, CE, BIS, and RoHS, and familiarity with IEC standards for PCB design safety.
• Coordinate with test engineers on board bring-up and PCB validation; run circuit simulations for RF and signal/timing optimization.

Ownership & Collaboration

• Independently manage hardware projects end-to-end, including vendor coordination and delivery of final hardware.
• Collaborate with mechanical engineers to optimize designs and meet project timelines.
• Bring the latest design tools, methodologies, and industry best practices into the team.

REQUIRED QUALIFICATIONS

• Bachelor's or Master's in EEE, Electronics, or equivalent practical experience.
• 4+ years of hands-on hardware / PCB design experience, ideally in consumer electronics or wearables.
• Proficiency with a leading schematic and PCB toolchain (OrCAD / Allegro preferred).
• Proven track record taking a product from schematic through layout to volume production.
• Working knowledge of power electronics and active/passive component selection.
• Familiarity with global certifications (FCC, CE, BIS, RoHS) and IEC PCB safety standards.

PREFERRED / BONUS

• Experience with miniaturized high-density or rigid-flex designs.
• RF design experience (2.4 GHz / BLE, NFC, antenna tuning and matching).
• EMI/EMC design and pre-compliance testing experience.
• Low-power / battery-operated wearable product experience.
• Familiarity with reliability methods (DFMEA, derating) and RF / signal-timing circuit simulation.
