SQL, Python, and Java remain the most sought-after programming skills by employers, according to new research from System Design School. The study analysed job listings on Glassdoor, revealing the languages most frequently cited as required skills.
“In today’s competitive job market, having the right skills is more important than ever, and this data provides clear evidence of the programming languages employers are seeking,” commented Sheldon Chi, ex-Google engineer and creator of System Design School.
“Whether someone is just starting their career or looking to advance, understanding which languages are in demand can significantly improve job prospects and career trajectory.”
The findings highlight the dominance of SQL (Structured Query Language), with 2,291 job postings demanding proficiency in the language. Primarily used for database management, SQL’s advantages extend far beyond the realm of software development. As data analytics becomes increasingly integral to businesses across various sectors, SQL skills are highly transferable and valuable to a wide range of professionals.
Trailing behind SQL in second place is Python, with 1,488 job postings seeking expertise in the language. Python’s popularity stems from its simplicity, versatility, and extensive libraries, making it suitable for a diverse range of applications from web development to data science and machine learning.
Java secured the third position with 856 job postings. Renowned for its reliability, platform independence (“write once, run anywhere” capability), and extensive use in enterprise applications, Java remains a mainstay in industries spanning finance to Android app development.
JavaScript, the backbone of front-end web development, took fourth place with 674 job postings. Powering the functionality of countless websites and web applications, JavaScript’s versatility extends to back-end development with frameworks like Node.js, solidifying its status as a crucial skill for full-stack developers.
Top 10 in-demand programming languages:
| Rank | Programming language | Number of jobs |
| 1 | SQL | 2,291 |
| 2 | Python | 1,488 |
| 3 | Java | 856 |
| 4 | JavaScript | 674 |
| 5 | HTML5 | 572 |
| 6 | R | 535 |
| 7 | CSS | 490 |
| 8 | C# | 327 |
| 9 | SAS | 261 |
| 10 | C++ | 252 |
The research also highlighted the enduring importance of front-end technologies. HTML5 secured fifth place with 572 job postings—its ability to deliver rich multimedia experiences, interactive elements, and responsive designs across devices makes it indispensable for modern web development.
Chi encourages professionals to actively cultivate in-demand skills: “We encourage professionals to focus on these areas to enhance their employability and career growth. By continuously updating skillsets and staying informed about industry trends, people can position themselves as a valuable asset to potential employers.”
