ELECTRONICS HARDWARE & PCB DESIGN ENGINEER

Eraaz Tech is a technology company specializing in the design and development of modern digital products, including web applications, mobile applications, SaaS platforms, APIs, cloud solutions, and workflow automation systems. As we expand into integrated hardware and software solutions, we are looking for an experienced Electronics Hardware and PCB Design Engineer to help us develop reliable, production-ready electronic products for industrial automation, equipment monitoring, remote telemetry, embedded control, and process-control applications. Role OverviewWe are seeking an experienced Electronics Hardware and PCB Design Engineer to develop a custom industrial controller from initial concept through to a production-ready hardware solution. This is a complete electronics development role—not a PCB layout-only position. The selected engineer will be expected to assess technical requirements independently, recommend a robust and reusable hardware architecture, select appropriate components, develop schematics and PCB layouts, and support prototype bring-up, testing, troubleshooting, and production release. The position will initially be part-time, with the opportunity to transition into a full-time role based on performance, project requirements, and mutual agreement. Key ResponsibilitiesDevelop complete hardware architectures and evaluate practical design alternatives.Select and integrate microcontrollers, communication modules, sensors, storage, and control interfaces.Design custom microcontroller-based systems, including power, clock, reset, boot, programming, and debugging circuits.Design a protected power architecture supporting continuous operation from a 5–28 V DC external input.Develop regulated internal power rails and automatic rechargeable-battery backup functionality.Design industrial analog and digital inputs, high-speed pulse-counting interfaces, relay outputs, and protected transistor or MOSFET outputs.Integrate wired communication interfaces such as Ethernet, CAN, RS485, UART, SPI, and I²C.Support wireless and cellular communication module integration where required.Produce complete schematics, multilayer PCB layouts, bills of materials, connector pinouts, and MCU pin-allocation documentation.Conduct power-consumption, peak-load, voltage-drop, and thermal-budget calculations.Apply grounding, signal-integrity, EMI/EMC, electrical-protection, creepage, clearance, and isolation best practices.Prepare complete fabrication and assembly packages for PCB manufacturers.Support prototype assembly, hardware bring-up, debugging, functional testing, and design validation.Identify technical risks, document engineering trade-offs, and resolve issues before production release.Coordinate with component suppliers, PCB manufacturers, assembly vendors, and software engineers when required.Maintain design revisions and prepare production-ready technical documentation.Required Skills and ExperienceMinimum 3 years of professional experience in electronics hardware development and PCB design.Proven experience personally designing custom microcontroller-based PCBs.Strong understanding of DC-DC power-conversion systems, including buck, boost, and buck-boost topologies.Experience with battery charging, power-path management, reverse-polarity protection, surge suppression, overcurrent protection, and USB power isolation.Experience designing industrial communication interfaces such as Ethernet, CAN, RS485, UART, SPI, and I²C.Experience with protected industrial I/O, relay and MOSFET drivers, pulse inputs, analog signal conditioning, and industrial current-loop inputs.Strong knowledge of multilayer PCB design, stack-up planning, grounding, return paths, signal integrity, thermal management, and EMI/EMC-aware layout.Knowledge of controlled impedance, differential-pair routing, length matching, and high-speed digital design.Understanding of DFM, DFA, DFT, creepage, clearance, electrical separation, and design reliability.Practical experience bringing up, troubleshooting, testing, and validating assembled prototypes.Ability to interpret technical requirements and make independent engineering decisions.Proficiency with PCB design tools such as Altium Designer, KiCad, Cadence Allegro, OrCAD, Siemens Xpedition/PADS, or equivalent.Ability to clearly document design decisions, assumptions, risks, calculations, and test results.Preferred QualificationsExperience developing electronics for industrial automation, embedded systems, telemetry, equipment monitoring, automotive, aerospace, or other high-reliability environments.Experience integrating wireless, Wi-Fi, Bluetooth, GNSS, LoRa, LTE, or other cellular modules.Experience with multiprocessor or multi-MCU architectures.Familiarity with IPC PCB design and manufacturing standards.Experience with high-density or advanced multilayer PCB designs.Understanding of firmware development and hardware–software integration.Experience communicating directly with PCB fabrication and assembly vendors.Knowledge of certification-oriented design practices and environmental testing is an advantage.Project Design ConsiderationsThe planned controller family may include multiple communication and processing configurations. The selected engineer should be comfortable designing a reusable hardware platform and explaining the cost, size, power, thermal, sourcing, reliability, and manufacturing trade-offs of different options. The 5–28 V requirement applies to the protected external power input. The design proposal must clearly explain how the required regulated internal rails, battery charging, communication modules, and peak-load functions will be maintained when the external supply is at the minimum 5 V input, including protection and conversion-stage voltage drops. Expected DeliverablesProposed system-level hardware architecture.Component recommendations and documented selection decisions.Fully editable schematic and PCB source files.Complete bill of materials with manufacturer part numbers and suitable alternatives.MCU pin-allocation documentation and connector pinouts.PCB stack-up and controlled-impedance requirements, where applicable.Gerber or ODB++ files, NC drill files, and fabrication drawings.Pick-and-place data and assembly drawings.Power-consumption, peak-load, and thermal-budget documentation.Interface electrical ratings and protection details.Hardware validation and prototype test plan.Prototype bring-up and functional test results.Support for debugging, design corrections, and engineering revisions.Production-ready final design documentation, subject to the agreed project scope.How to ApplyPlease apply directly through LinkedIn or email your CV to hr@eraaztech.com. Your application should include: A short professional introduction.Examples of relevant custom PCBs you personally designed.Schematics, PCB layouts, or assembled-board photographs where available.A clear explanation of your contribution to each referenced project.Details of your experience with prototype bring-up, testing, and troubleshooting.Your preferred PCB design tools.Your current availability and estimated project timeline.Your expected hourly rate, monthly compensation, or proposed milestone-based arrangement.A brief explanation of how you would approach the 5–28 V wide-input power system, rechargeable-battery backup, and overall controller architecture.Detailed technical requirements will be shared with shortlisted applicants for review and quotation.
