Job Description

We’re looking for a Hardware & Embedded Systems Engineer who enjoys turning ideas into physical, working products - from first schematic to production line.

If you enjoy board bring-up, firmware debugging, signal analysis, low-power optimisation, and seeing devices survive real-world abuse - you’ll feel at home here.

This is not a “hardware-only” or “firmware-only” role.

You’ll work across hardware design, embedded firmware, validation, industrial design collaboration, RF optimisation, and manufacturing - seeing your work through the full product lifecycle.

What You’ll Do

Hardware Development

• Design and review schematics and multi-layer PCBs (KiCAD preferred)
• Select and validate components for connectivity, sensing, and power systems
• Develop and debug IoT hardware platforms using ESP32, STM32, or similar MCUs
• Perform bench-level troubleshooting, signal analysis, and power characterisation using oscilloscopes, logic analysers, and spectrum analysers
• Support RF, EMC, and compliance pre-certification activities
• Own board bring-up and early hardware validation
  
  

You’ll take a design off the screen and turn it into a working, connected device.

Embedded Firmware Development

• Develop production-grade embedded firmware in C/C++
• Implement and debug peripheral drivers (SPI, I2C, UART, ADC, etc.)
• Work with RTOS-based systems (e.g. FreeRTOS)
• Integrate wireless and wired interfaces (Wi-Fi, BLE, LTE, RS485, MQTT)
• Support low-level debugging during bring-up and field issue investigation
  
  

You’ll be as comfortable in a debugger as you are with a scope.

Product Development & Industrial Collaboration

• Work closely with Industrial Design from early concept stage through to production
• Influence enclosure design, internal architecture, antenna placement, thermals, and ingress protection
• Balance aesthetics, RF performance, reliability, and manufacturability
• Help shape not just the PCB - but the entire product
  
  

You won’t just design a board. You’ll help craft the device.

Prototype & Validation Engineering

• Develop structured validation and characterisation plans
• Perform reliability, power-performance, environmental, and RF testing
• Conduct root-cause analysis of hardware and firmware issues
• Improve robustness and repeatability of prototype designs
  
  

We value engineers who ask “why did that happen?” and won’t stop until they know.

Test & Manufacturing Support

• Design and develop production test fixtures and validation jigs
• Develop test automation tools (Python, C#, or embedded test firmware)
• Contribute to DFM and DFT decisions during hardware design
• Work with manufacturing partners to ensure scalable, testable production
  
  

You’ll help ensure what we design can actually ship - reliably and at scale.

Requirements

What We’re Looking For:

• BSc, BEng, BTech, or equivalent in Electronic, Electrical, or Mechatronic Engineering
• 4–8 years of experience in hardware and embedded systems development
• Proven contribution to commercially deployed IoT or connected hardware products
• Strong schematic and PCB design experience
• Solid embedded C/C++ proficiency (bare-metal and/or RTOS-based systems)
• Hands-on experience with lab equipment (oscilloscopes, logic analysers, power measurement tools, spectrum analysers)
• Strong understanding of analog, digital, RF, and power electronics fundamentals
• Experience supporting or developing production test systems
• Comfortable working across hardware, firmware, and manufacturing domains
• Experience with Git and collaborative engineering workflows
  
  

Bonus Points For

• Experience with ESP32, STM32, or similar MCU platforms
• Low-power and battery-operated system design
• Antenna design and impedance matching experience
• RF validation, wireless certification, or EMC pre-compliance testing
• Experience with LTE, Sigfox, LoRa, or other IoT connectivity technologies
• Python-based test automation
• Familiarity with DFM/DFT and small-to-medium scale manufacturing
• Mechanical prototyping or 3D CAD experience
  
  

Benefits

• Exciting Workspace.
• Cutting-Edge Technology.
• Engaging Projects and Innovations.
• High-Tech Atmosphere.
• Versatile Experience - Get exposure to a wide range of things.
• Involvement in Manufacturing Processes - End-to-End Involvement.
• Inspiring Work Environment.
• Opportunity for Career Growth and Continuous Learning - Cross-Functional Teams.
• Contributing to a South African Company with a real impact on people's lives.
• Olarm Device and Subscription.
  
  

Are you ready to embark on a journey that's both professionally fulfilling and personally rewarding? If you're excited about technology, driven by results, and thrive in a collaborative environment, Olarm is the place for you. Join us in shaping the future of smart security solutions!
