Is It Still Worth Learning Embedded Engineering Today?

Five years ago embedded engineers were highly sought after, earning decent salaries while the IoT boom created abundant opportunities; even a developer familiar with STM32 could easily find work. Today the market has become fiercely competitive: recent graduates list skills like ARM architecture, RTOS, and PCB design, yet often cannot explain basic concepts such as interrupt priority during interviews.

Demand for embedded positions is shrinking, while training programs continue to churn out thousands of so‑called "embedded engineers." The required technology stack has grown dramatically—engineers now need to understand the Linux kernel, driver development, numerous communication protocols, and even AI inference deployment. Learning only Arduino is merely an introductory step.

The return on investment is low. Acquiring development boards, oscilloscopes, and logic analyzers costs several thousand dollars, and the learning curve is long because both hardware and software expertise are required. Salary ceilings are modest: unless one joins top firms like Huawei HiSilicon or DJI, most engineers plateau around ¥200,000 annual income, whereas software developers at major internet companies can earn ¥400,000–¥500,000 after a few years. Overtime demands are comparable, and hardware failures often require 24‑hour on‑call support.

Industry segmentation is evident. High‑end roles—such as autonomous driving, industrial robotics, and high‑performance computing—demand deep hardware knowledge, algorithms, and system architecture, and are typically filled by elite graduates from top universities. Low‑end work on consumer electronics and small‑appliance microcontrollers is oversaturated, with outsourcing firms in Shenzhen paying as little as ¥5,000 per month for long hours, offering little technical depth and high replaceability.

Traditional mid‑level embedded positions (driver development, application‑level coding) are being squeezed out by vendor SDKs and open‑source solutions, and companies are increasingly reluctant to retain engineers who fall between hardware and software specialties.

For those still considering entering the field, the author advises clear motivation: do not assume embedded work is simpler than pure software, recognize the steep learning curve, and be prepared for limited short‑term rewards. Genuine passion for hardware and a willingness to self‑study—purchasing development boards, troubleshooting bugs, and gaining hands‑on experience—are essential, as training courses alone cannot provide the necessary practical skills.
