The programming landscape is often dominated by modern languages like Rust and TypeScript, but several legacy languages continue to play crucial roles in various industries. These languages, though considered outdated, can provide unique job opportunities for those willing to learn them.
COBOL: The Backbone of Financial Systems
The Common Business-Oriented Language (COBOL), developed in 1960, remains integral to many financial systems today. It was designed to facilitate communication between technical and non-technical stakeholders using a syntax that resembles plain English. Despite its age, COBOL is responsible for handling approximately 95% of ATM transactions and 40% of online banking systems. The language primarily operates on mainframe computers, processing vast amounts of data for various industries.
While many COBOL systems are in maintenance mode, the demand for COBOL developers persists, particularly in the financial sector. According to Franklin University, the median salary for COBOL developers is around $99,000, with experienced professionals earning up to $167,000.
Ada: High-Assurance Applications
Ada, named after Ada Lovelace, emerged in the early 1980s as a project initiated by the Department of Defense (DoD). It is specifically designed for embedded and real-time systems where reliability is paramount, such as in avionics and military applications. Ada emphasizes code correctness and features like design-by-contract, which helps ensure program integrity.
Although its popularity waned after the DoD dropped its Ada mandate in the 1990s, recent trends towards memory-safe programming have revived interest in Ada. In 2025, it ranked among the top ten languages in the TIOBE Programming Community Index. Salaries for Ada developers range from $86,000 to $113,000, depending on experience.
Perl: The Early Web’s Scripting Language
Introduced in 1987, Perl is a general-purpose scripting language known for its flexibility and powerful string processing capabilities. It played a significant role in the early web, particularly in CGI scripts that facilitated backend operations. Despite its decline in popularity, legacy Perl code is still prevalent, with over 39,000 companies actively seeking Perl skills.
The average salary for Perl developers is approximately $106,000, reflecting its continued relevance in certain sectors.
Conclusion: Niche Skills for Job Security
While the tech industry often focuses on newer languages, understanding legacy programming languages like COBOL, Ada, and Perl can provide significant job security. These languages may not be the most glamorous, but they offer valuable skills that are still in demand across various industries. As the programming landscape evolves, having knowledge of these legacy systems can set candidates apart in a competitive job market.
