Embedded Systems Development

With expertise in Embedded Systems Development, you become the programmer of hardware. Microcontrollers, sensors, IoT devices—you write code that runs on tiny computers with limited memory and no operating system. Your software controls real physical things in the real world.

What You'll Actually Be Doing

As the Embedded Systems Development go-to person, you might spend your morning writing C code for a microcontroller with 32KB of RAM (welcome to resource constraints), then debugging why the sensor isn't reading correctly (turns out it's a hardware issue), followed by optimizing power consumption because the device needs to run on a battery for 5 years.
  • Develop firmware for microcontrollers and embedded devices
  • Work with hardware constraints and limited resources
  • Implement communication protocols like SPI, I2C, UART, and CAN
  • Program Real-Time Operating Systems (RTOS)
  • Debug with hardware tools like JTAG and oscilloscopes
  • Optimize for power consumption and memory efficiency

Communication Protocols

ESSENTIAL
MQTT, I2C, SPI, UART, Serial communication
MQTT appears in <5% of Embedded Systems Developer postings. I2C, SPI, UART appear minimally but are fundamental embedded communication protocols. These explicit mentions understate importance—protocol implementation is core to embedded work. Understanding serial buses and IoT protocols is assumed baseline.

Security & Trusted Execution

ADVANCED
Secure Boot, TrustZone, Trusted Execution Environment, Encryption
Secure Boot appears in <5% of Embedded Systems Developer postings. TrustZone and TEE appear minimally. Security expertise represents advanced embedded specialization—implementing secure boot chains, trusted execution, and cryptography at firmware level. Increasingly important but typically senior-level depth.

Testing & Simulation Tools

COMPLEMENTARY
MATLAB/Simulink, Hardware simulators, Testing frameworks
MATLAB/Simulink appears in <5% of Embedded Systems Developer postings. Testing and simulation tools complement embedded development for model-based design and hardware-in-the-loop testing. Particularly valuable in automotive and aerospace embedded systems.

What Separates Good from Great Engineers

Technical differentiators:

  • Resource-constrained optimization (memory, power, processing)
  • Real-time system design and meeting timing requirements
  • Understanding hardware-software interaction and peripheral programming
  • Debugging techniques for systems without traditional debugging tools

Career differentiators:

  • Working across hardware and software teams effectively

  • Creating testing strategies for hardware-dependent code
  • Understanding the cost implications of design decisions in hardware
Your value isn't in writing C code—it's in building reliable embedded systems that work in the real world with real constraints. Great embedded engineers think holistically about the hardware-software system, not just code.
