This paper examines the career and marketability implications of UNIX expertise in the modern enterprise environment. It surveys the dominant role UNIX plays as the foundational operating system across enterprise computing, Linux distributions, and mobile platforms such as Google Android and Apple iOS. The paper outlines the technical skill sets — including shell scripting, database administration, and programming languages — that command high salaries and career advancement. It also addresses the strategic importance of certifications and the need for UNIX professionals to plan proactively against technological obsolescence. Together, these themes form a practical framework for building and sustaining a long-term career in UNIX-related fields.
UNIX is the most widely used operating system powering enterprise computing today, surpassing Microsoft Windows and all other operating systems combined. UNIX is also the foundation of Linux operating systems, many variants of open source software, and serves as a significant theoretical basis for the Google Android operating system (Sen, Singh, & Borle, 2012). As a result of its pervasive adoption and widespread standardization, career opportunities in UNIX are very significant. Salaries for these positions vary by the difficulty of the work involved, the difficulty of replacing the person performing it, and the breadth of experience a job candidate possesses (MacInnis, 2006).
The future for those with UNIX programming and development skills is being further accelerated by the rapid adoption of Linux as the foundational operating system of enterprises today, specifically in the areas of Enterprise Resource Planning (ERP) integration, transaction management, and database management and administration (de Brulin, Bos, & Bal, 2011). The highest growth opportunities for those with UNIX programming and software development skills, however, lie in web application development and the creation of mobile applications for the Google Android and Apple iOS operating systems. Of these two, UNIX has had a far greater influence on the development and continual refinement of Android, as Google sought to bring this operating system to tablets, smartphones, and mini-tablets during the 2012–2013 timeframe (Sen, Singh, & Borle, 2012).
For those more interested in the administration and management of enterprise systems, there is also the role of system administrator, which can over time become a career path leading to system manager and eventually IT Director of Infrastructure (Dobb, 2011). This analysis evaluates the current state of UNIX and job marketability, focusing specifically on how Linux, Google Android, and Apple iOS operating system development represent some of the fastest-growing areas of programming employment. These three areas are also heavily based on the fundamental concepts of UNIX, as the creators of these platforms are focused on building scalable, secure, and stable operating systems that support mass adoption of the applications built upon them.
Since the majority of enterprises today run on UNIX, the majority of jobs for those with UNIX administration and programming skills are found in larger enterprises running distributed applications — most often in conjunction with complex, enterprise-wide databases (MacInnis, 2006). Current UNIX skills that are most marketable in these larger enterprises, which often have hundreds of millions of dollars invested in their systems, include SQL query writing and Oracle database administration and management (de Brulin, Bos, & Bal, 2011). Additional in-demand skills include managing complex data structures and the ability to design and create them quickly, while aligning those structures to business problems within large organizations.
The role of the UNIX developer in Fortune 1,000 companies — the largest corporations listed annually in Fortune magazine's ranking of the top one thousand firms — also requires intensive training in analytics, accounting, and financial reporting application expertise, extending to the data warehouse and data table levels (MacInnis, 2006). These skill sets are critical for UNIX developers in enterprises, as they often must also create highly specific transaction processing and order management systems and queues to streamline integration between legacy, third-party, and very large-scale enterprise systems (Dobb, 2011). In this regard, the UNIX developer also acts as a system architect, ensuring that the overall complex of systems within an enterprise can integrate with one another in real time while simultaneously giving business units the agility and flexibility to accomplish their goals and initiatives (de Brulin, Bos, & Bal, 2011).
UNIX developers are expected to have a high level of expertise in shell scripting, including Korn and PERL scripting languages, with Python — the scripting language popularized in part by Google — also becoming increasingly prevalent (de Brulin, Bos, & Bal, 2011). UNIX developers with these skill sets often create shell scripts for managing complex transactions and automating workflows across various systems through embedded commands that drive system integration and data routing. This expertise in data routing and integration is critical in enterprise environments, as the insight and capability of UNIX developers often keep entire organizations moving toward their objectives.
