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.

• 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.

Job Title: CAD Design Engineer, Mechanical & Code-First Reverse Engineering

Location: Gurugram | Bengaluru| Hyderabad | Pune (On-site)

Type: Full-Time

Experience: 5+ years

About the Role

We are seeking an experienced CAD professional with strong expertise in 3D modelling, part and assembly design, and technical drafting. In this role, you will create and refine high-quality CAD models and engineering drawings, develop robust design workflows, and collaborate with engineering teams to deliver accurate, manufacturable, and production-ready designs.

What You'll Do

● Create and review data grounded in real CAD and mechanical design practice, parts, assemblies, drawings, and the reasoning behind them.

● Reverse-engineer geometry: take an STL/mesh with no feature history and reconstruct the design intent as parametric, code-first CAD (build123d), inferring sketches, features, datums, patterns, and key dimensional relationships.

● Evaluate AI-generated design solutions, 3D models, feature trees, mating strategies, drawings, and pin down failure cases, edge cases, and quality gaps.

● Decompose complex modelling and verification tasks into structured, step-by-step workflows the model can learn from and be measured against.

Domain Responsibilities

● Build and assess parametric models, assemblies, and detailed 2D drawings across machined, sheet-metal, cast/moulded, and weldment parts.

● Judge design intent, constraints, and robustness, modelling approach. ● Apply and check GD&T, tolerancing, and design-for-manufacturing across the full product design lifecycle (concept → detailing → design review → handoff).

● Validate code-first reconstructions against source geometry via deviation and dimensional-accuracy checks.

Requirements

Must Have

● B.E./B.Tech/M.Tech/Ph.D in Mechanical Engineering (or closely related) from a Tier 1/Tier 2 institute (IIT, NIT, BITS, IIIT, DTU/NSUT, or equivalent).

● 5+ years of hands-on CAD/mechanical design with breadth across multiple platforms (Autodesk Fusion, SolidWorks, Creo, NX, CATIA, or Inventor), multiple part types, and the full design workflow.

● Strong command of parametric modelling, assembly design, engineering drawings, GD&T, and DFM.

● Working Python ability and genuine comfort with code-first CAD (build123d / CadQuery), or a clear track record of picking up scripting fast.

Good to Have

● Mesh processing (trimesh, Open3D, numpy-stl) and familiarity with OpenCascade/OCCT.

● Exposure to adjacent disciplines, surfacing, simulation-driven design, generative/topology optimization, or CAM handoff.

● PLM/PDM and configuration management.
