Job description:

1.1 Position Summary

The Senior Hardware Design Engineer owns the hardware design of embedded electronic products — IoT / IIoT / AIoT gateways, industrial automation controllers, and related embedded systems — from a given system block diagram through schematic capture, PCB layout, BOM optimization, prototyping, testing, certification, and handover to production. The role carries end-to-end accountability for translating a functional/system requirement into a manufacturable, certifiable, field-reliable product, working closely with firmware, mechanical, product management, and manufacturing teams.

1.2 Key Responsibilities

A. Circuit Design & Schematic Development.

Own circuit design from concept to final schematic — component selection, topology decisions (power, analog, digital, RF/wireless, protection), and design-margin analysis.
Prepare schematics and footprints in line with design-for-manufacture (DFM) and design-for-test (DFT) norms; own the component library (symbols, footprints, 3D models).
Perform worst-case analysis, thermal and power-budget calculations, and signal-/power-integrity checks before layout release.

B. End-to-End Product Design & Cross-Functional Delivery.

Take ownership of end-to-end hardware product design starting from the system block diagram / functional requirement handed over by architecture, product, or firmware teams.
Convert the block diagram into a detailed design plan: architecture partitioning, interface definition, connector/pinout strategy, and design & test standard operating procedures (SOPs) to be followed for the project.
Collaborate continuously with firmware, product management, mechanical, and quality teams to align hardware decisions with product goals, cost targets, and schedule.
Drive BOM optimization for cost, lead time, second-sourcing, and long-term (life-of-product) component availability.

C. Embedded Product Design — IoT / IIoT / AIoT / Automation.

Design embedded hardware for IoT/IIoT/AIoT gateways, edge-compute nodes, and industrial automation products — including processor/SoM selection, connectivity (Wi-Fi/BLE/cellular/LoRa/Ethernet/RS-485/Modbus), and sensor/actuator interfacing.
Consider enclosure, mounting, and installation requirements (IP rating, DIN-rail/panel mount, connector placement, cable entry) as part of the hardware design, in coordination with mechanical/industrial design.
Design for long, unattended field life — component derating, thermal management, surge/ESD/EMI protection, watchdogs, and firmware-assisted fail-safe hardware features.

D. High-Level & Functional Block Diagrams.

Generate high-level design and functional block diagrams from system requirements where one is not already provided, to align stakeholders before detailed design starts.

E. Testing, Validation, Compliance & Certification.

Define and execute the test plan for each product as per applicable hardware product standards — functional test, environmental (temperature/humidity/vibration), EMC/EMI, safety, and long-duration burn-in / life testing.
Identify applicable regulatory and safety standards for each product/market (e.g., CE, FCC, BIS/CDSCO, IEC 61000/60950/62368, UL, RoHS/REACH) and plan pre-compliance and formal lab testing accordingly.
Coordinate with external test/certification labs to get products tested and certified; own closure of non-conformances raised during certification.
Test hardware components individually and in conjunction with external/integrated systems; conduct functionality and performance testing of final products against specification.

F. Sustaining Engineering & Documentation.

Analyze field/system data to define and implement hardware configuration or revision changes.
Perform root-cause analysis (RCA) and troubleshoot hardware defects; define and implement preventive/corrective actions to minimize recurrence.
Provide technical support to production, field service, and customers for hardware-related issues; support initial board bring-up and low-level validation.
Create and maintain specifications and documentation for components, sub-systems and complete systems (design docs, test reports, DFM/DFMEA records, certification files).
Stay current with emerging components, tools, and technologies, and evaluate their applicability to existing and future products.

1.3 Required Skills, Tools & Experience

Hands-on proficiency in Altium Designer and/or OrCAD (schematic capture, PCB layout, library management); familiarity with simulation tools (SPICE-based circuit simulation, signal-/power-integrity tools).
Demonstrated experience across the full hardware product lifecycle: concept → schematic/layout → prototype → DFM → EMC/safety pre-compliance and certification → handover to production.
Strong fundamentals in Analog, digital, power electronics, and embedded processor/microcontroller-based design.
Strong low-level software skills and ability to perform initial board bring-up (register-level debug, boot-loader/BSP checks); exposure to Embedded Linux (device tree, kernel drivers, bring-up on SoM/SoC platforms) is a strong plus.
Working knowledge of applicable EMC, safety, and product-certification standards relevant to industrial/IoT electronics.
Bachelor's/Master's degree in Electronics/Electrical/Embedded Engineering with typically 3–8+ years of relevant hardware design experience.
