The six best-paid IoT programming languages
C: The key programming language for embedded devices
The C programming language is next in line as a favorite language for IoT stacks. However, it is considered a leading technology when it comes to constrained device development, according to the Eclipse Foundation.
This programming language provides direct access to low-level hardware APIs. Owing to its similarities with machine language, C is extremely fast and flexible, making it a perfect match for IoT systems with limited processing power.
Similar to Java, C developer salaries vary considerably around the world. In the United States, a C developer can expect to earn around $100k per year, while in Switzerland, the average annual salary of a C developer is $92k. Among the countries we have analyzed, the lowest salaries for C experts can be found in the United Kingdom. According to Payscale, the annual average C developer salary in the United Kingdom is only just over the $40k mark.

There is also significant deviation between the salaries of junior and senior C developers. Senior C developers earn almost twice as much as entry-level employees in both the United States and the United Kingdom.

C++: Number one language for Linux
Similar to its predecessor, C, C++ has been used extensively in embedded system development. However, the main advantage of C++ is in processing power, making it a useful alternative to C when the task is more complex.
C++ is best for writing hardware-specific code. It works well with Linux, the number one IoT operating system. However, in comparison to Java, it has a limited portability.
C++ engineers can expect lower salaries than C developers. Our research found that C++ developers can expect to get around $82-86k in Israel and Denmark, while in the United States this figure was a lowly $71k.

However, despite the low average rates for C++ developers in the United States, experienced specialists can hit six figures later in their careers.

Python: The solution for data-heavy IoT systems
As one of the most popular web programming languages, and a go-to technology for scientific computing, Python has gained a significant traction in the IoT development as well. Python is a good choice for data-intensive applications, especially when it comes to managing and organizing complex data.
Moreover, source code written in Python is compact and extremely readable thanks to the language’s clean syntax. This works especially well with small devices that have limited computational power and memory, albeit not as fast as C/C++.
Average Python developer salaries in the United States hover around the $71k mark, while developers with similar skillsets can expect to earn around $68-67k in Israel and Switzerland respectively.

As ever, there is a substantial pay gap between junior and senior-level Python developers.

A closer look at the number reveals that despite a relatively low national average, Python developer salaries in the United States can be very high on an individual basis. Owing to soaring demand for developers and a limited supply, salaries can reach as high as $142k in certain states. Traditionally, California is among the states that offer the highest salaries for tech specialists. Local Python developers there earn about $135K on average.
