About the Company

Unnayan Defence Technologies is a Hyderabad-based defence startup focused on developing innovative, indigenous solutions to strengthen national security. With a strong emphasis on in-house research and development, the company designs proprietary technologies that cater to India's defence needs while also contributing to global defence exports. The team works in a fast-paced R&D environment with a focus on designing, prototyping, and manufacturing high-reliability electronic hardware for defence, aerospace, and industrial applications.

Role Overview

We are looking for a skilled Senior Embedded Hardware Engineer with 5–8 years of experience to design, develop, test, and validate electronic hardware for embedded and defence-grade applications. The ideal candidate will have strong knowledge of analog and digital circuit design, multi-layer PCB development, component selection, hardware debugging, and product validation. You will collaborate closely with embedded software, mechanical, and production teams to bring reliable, high-performance products from concept to manufacturing.

Key Responsibilities

• Design analog and digital electronic circuits based on project requirements.
• Develop schematics and multi-layer PCB layouts using industry-standard EDA tools.
• Select electronic components considering performance, cost, and availability.
• Design power supply circuits, signal conditioning circuits, and interface circuits.
• Work with microcontrollers, processors, sensors, and communication modules.
• Perform circuit simulation and hardware validation to ensure design integrity.
• Debug hardware using oscilloscopes, logic analyzers, DMMs, power supplies, and function generators.
• Support PCB fabrication, assembly, and prototype bring-up.
• Troubleshoot hardware issues and implement design improvements.
• Prepare hardware design documents, BOMs, schematics, test reports, and manufacturing documents.
• Collaborate with Embedded Software, Mechanical, and Production teams throughout the product development lifecycle.
• Ensure designs comply with EMI/EMC, reliability, and quality standards.
• Contribute to design for manufacturability (DFM) and design for test (DFT) using IPC standards.
