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:

Strong Product Design Engineer Profile that combines strong product design with hands-on frontend coding

2

Mandatory (Experience 1): Must have 2+ years in product design, with strong depth in dense, complex product interfaces (tables, forms, permissions, multi-role flows) built for real users

3

Mandatory (Experience 2): Must have strong product / visual design judgment along with the ability to ship production-ready frontend code independently. Not a designer who only vibe-codes, and not an engineer who dabbles in UI.

4

Mandatory (Frontend Tech Skills 2): Must be able to set guardrails and standards so AI tools generate clean, production-ready, accessible code that follows the component system, removing the need for a frontend engineer to review design-team code.

6

Mandatory (Portfolio): Must share a GitHub profile and a link to a real product prototype they designed and coded end-to-end. Must show shipped, interactive product UIs. Landing pages, marketing sites, dummy projects, case studies, and Figma / Behance / Dribbble-only portfolios will not be considered.

7

Mandatory (Communication): Must have excellent English communication and be able to clearly articulate their thought process (works with US stakeholders).

8

Mandatory (Company): B2B SaaS background (dense tables / data); early stage startups where design and engineering were not separate functions will also work

9

Mandatory (Exclusion 1): Must not position as Engineer / Developer / PM in their resume. This is a designer-first profile.

10

Mandatory (Exclusion 2): Must not be from big corporates / MNCs (1000+ employees, e.g. Infosys, Wipro) or IT services companies / agencies.

11

Preferred (Profile): Designer-first, engineer-second, with titles like Product Designer, Design Engineer, Design Builder, or Design Technologist; ideally moved from a design role into design-engineering.

12

Preferred (AI): Experience with AI-native interfaces (streaming output, agentic / human-in-the-loop UX, confidence / uncertainty in UI); AI used structurally in shipping features, not just for copy or assets.
