Unveiling the Skills and Responsibilities of Serverless Practitioners: An Empirical Investigation

Abstract

Enterprises are increasingly adopting serverless computing to enhance scalability, reduce costs, and improve efficiency. However, this shift introduces new responsibilities and necessitates a distinct set of skills for practitioners. This study aims to identify and organize the industry requirements for serverless practitioners by conducting a qualitative analysis of 141 job advertisements from seven countries. We developed comprehensive taxonomies of roles, responsibilities, and skills, categorizing 19 responsibilities into four themes: software development, infrastructure and operations, professional development and leadership, and software business. Additionally, we identified 28 hard skills mapped into seven themes and 32 soft skills mapped into eight themes, with the six most demanded soft skills being communication proficiency, continuous learning and adaptability, collaborative teamwork, problem-solving and analytical skills, leadership excellence, and project management. Our findings contribute to understanding the organizational structures and training requirements for effective serverless computing adoption.
