Pretoria East: Embedded engineer posted by Network Finance

We’re developing innovative IoT systems that integrate sensors, embedded firmware, and cloud connectivity — and we’re looking for a hands-on engineer to bring our hardware to life.

As our Embedded Systems & PCB Design Engineer, you’ll be responsible for designing custom electronics, programming firmware for microcontrollers, and integrating various sensors into reliable, production-ready IoT devices.

Key Responsibilities

– Design and develop firmware for embedded microcontrollers (e.g. EFM32, ESP32)
– Design, layout, and test PCB boards using tools such as KiCad, Altium, or Eagle
– Integrate and calibrate sensors (temperature, pressure, flow, GPS, etc.)
– Implement and test communication protocols (I2C, SPI, UART, CAN)
– Develop and optimize wireless connectivity (Wi-Fi, BLE, LoRa, NB-IoT, GSM, LTE)
– Collaborate with software/cloud teams for end-to-end IoT integration
– Prototype, test, and debug using lab equipment (oscilloscope, logic analyzer, etc.)
– Prepare production documentation and support hardware manufacturing partners
– Fault finding and repair of PCB’s, electrical and electronic assemblies.
– Technical support for projects and support for new designs.
– Participate in project technical reviews.
– Provide mentorship and technical guidance to other members of the discipline.
– Provide input into Skills Development/Training and contribute to discipline-specific 
training where applicable.
– Assist with the procurement, maintenance, training in use of discipline specific Tools.
– Implement and maintain version control processes for firmware development using Git 
repositories.
– Able to make adjustments on all existing firmware projects.
– Assist and generate necessary engineering documentation related to the work being executed.
– Support the Company proposal/quotation generation process.
– Assist with budgeting for capital expenditure and expenses.
– Assist with creating BOMs for products and update when changes are implemented.

Requirements

– 3+ years experience in embedded systems and PCB design
– A minimum of an BEng in Electronic or Computer Engineering
– Strong in C/C++ programming for embedded systems
– Experience with sensor integration and analog/digital signal interfacing
– Familiarity with IoT communication protocols (MQTT, CoAP, REST)
– Working knowledge of power management and low-power design
– Experience with hardware bring-up, testing, and troubleshooting
– Advantageous: experience with OTA updates, device provisioning, or cloud IoT platforms (AWS IoT, Azure IoT, etc.)
