Average junior backend developer salary

The average salary for entry-level backend developers in South Africa starts at an average of R27 225 per month, 25.9% (R5 595) more than they did in 2022. That means they start out earning 22.8% (R5 054) more than entry-level full stack developers and a whopping 33.5% (R6 838) more than their frontend counterparts.

After two years on the job, junior backend developers see their salary rise by 30.1% (R8 183) to a monthly average of R35 408. At this stage of their careers, they earn 11.5% (R3 641) more than full stack developers and R8 226 more than frontend developers with comparable experience.

Mid-level backend developers can expect the most significant salary increase of their careers once they pass the four-year mark. Once they have at least four years of experience, they can expect a 43.4% (R15 376) increase. This gives them an average salary of R50 784, 10.7% (R4 919) and 30.4% (R11 842) more than their full stack and frontend counterparts, respectively.

The constantly growing demand for backend developers, coupled with the fact that more junior developers tend to switch jobs more often and thus negotiate for fresh salaries, can likely explain why their earnings rise so rapidly during this phase of their careers.

Average senior backend developer salary

Once they reach the senior level, backend developers can expect a 37.5% (R19 025) pay rise. This puts the average monthly salary for backend developers with at least six years of experience at R69 809 – 9.9% (R6 267) more than 2022's average. At this stage, their advantage over full stack developers has grown slightly to 13.7% (R8 391), but it has narrowed to 17.7% (R10 521) for frontend developers.

After they've been in the profession for more than ten years, senior backend developers see their salaries grow by another 30.4% (R21 234) to R91 043. On the other hand, full stack developers with comparable experience earn 11.1% (R9 100) less, while their frontend counterparts earn 27.8% (R19 829) less at this experience level.

Senior backend developers are typically responsible for the whole product development life cycle, including designing, developing, deploying and maintaining new and existing features and overseeing junior developers' teams. As such, they continue to see notable salary increases as they grow in seniority.

Keep in mind

The data in this article comes from OfferZen's 2023 State of the Software Developer Nation Report. In this article, 'salary' refers to the gross monthly salary (before tax) provided by more than 4500 survey respondents.

Average salaries are single data points and only one part of a bigger story. Many respondents are expected to earn significantly more or less than these averages. However, we aim to provide a picture of underlying trends by mapping the average salaries for different experience levels.

These averages should not be used to estimate what your actual salary will or should be.

Salaries depend on the industry, individual, perks and nature of work. These factors influence the salary a company will offer prospective hires. In addition, most developers are "fluent" in several languages, which will affect the final figures.

It's also important to remember that every individual's context is different. Ultimately, salary is a personal conversation that should take place between employee and employer.
