ULTRAHUMAN • HARDWARE

Hardware Design Engineer Wearables

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

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 I²C/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.

ROLE SUMMARY:

An experienced, hands-on engineering role owning the electrical and electronics hardware content of motor-drive and sensor systems. The Electrical / Electronics / Instrumentation Engineer is responsible for power distribution and motor-drive power-stage design, sensor interface boards, and taking boards through EMI/EMC compliance, with full ownership of schematic capture and layout from concept to fab-ready.

RESPONSIBILITIES:

• Design power distribution and the motor-drive power stage (gate drives, current sense, H-bridge/inverter stages)
• Implement supervised discrete-line circuitry per IF-08 ICD requirements
• Design sensor interface boards (resolver, encoder, analog/digital signal conditioning)
• Take boards through EMI/EMC compliance for MIL-STD-461
• Own schematic capture and layout in Altium or KiCad end-to-end, from concept to fab ready.

REQUIRED QUALIFICATIONS

• B.E./B.Tech/M.E./M.Tech. in Electrical, Electronics & Communication, Electronics & Instrumentation, or any other relevant field.
• 4-8 years of relevant experience.

KEY COMPETENCIES

• Hands-on power electronics: gate driver design, current sensing, protection circuitry
• Analog signal conditioning for sensor front-ends (resolver, encoder, LVDT-class signals)
• Practical EMI/EMC design experience, ideally against MIL-STD-461 or equivalent (automotive/industrial EMC also considered)
• Strong Altium or KiCad skills — layout discipline for power + mixed-signal boards.
• Prior work on ICD-driven or interface-controlled discrete I/O circuitry
• Defence, aerospace, or automotive electronics background

• Provide technical job support for Automotive Embedded/ECU testing activities.
• Validate the MCU 5V reference voltage (VREF) under normal and fault conditions.
• Design and execute test cases for voltage monitoring and fault detection.
• Perform over-voltage and under-voltage fault injection.
• Monitor and validate Power-Good (PG) status during different voltage conditions.
• Capture and analyze ADC readings and compare them against expected values.
• Verify accurate detection of voltage-related faults.
• Validate ECU diagnostic behavior, fault codes, and reporting.
• Perform positive, negative, boundary, and fault-condition testing.
• Analyze test failures and perform root-cause analysis.
• Support debugging of ECU hardware/software issues.
• Review requirements, test specifications, and validation documents.
• Execute regression testing after software/firmware changes.
• Provide technical guidance and troubleshooting support as part of the job-support engagement.
