How to become a QA engineer 🪜
These fundamental steps and strategies will shape your career in quality assurance:
Education and experience 🎓
Becoming a QA engineer involves a combination of education and practical experience, both of which lay the foundation for a rewarding career. QA engineers typically possess a bachelor’s degree in computer science, engineering, or a related field, solidifying their knowledge base.
Aspiring QA engineer candidates are encouraged to accumulate two or more years of experience in software development, software testing, or similar roles. This hands-on exposure refines their skills in manual and automated software testing, testing analysis tools, and other aspects of software development.
A well-crafted QA engineer resume should showcase a candidate's experience in testing software, knowledge of testing frameworks, and any relevant certifications in the field.
Courses and certifications 📜
QA engineer courses and certifications allow you to elevate your skills and propel your career forward to discover a world of growth and expertise. Aspiring individuals can enhance their career prospects by enrolling in courses that cover topics like test automation, quality assurance methodologies, and software testing best practices.
Professional path 💼
Aspiring QA engineers often move forward after accumulating experience as software developers, software testers, and other related positions. During this journey, it’s important to distinguish between a QA engineer and a QA analyst.
QA engineers take on a multifaceted role that involves comprehensive testing, ensuring software integrity across systems. Meanwhile, QA analysts focus on meticulous testing processes and data analysis, contributing to enhanced software quality.
Although both roles involve ensuring software quality, comparing QA engineer versus QA analyst reveals that QA engineers often focus on technical testing aspects and automation. In contrast, QA analysts concentrate more on test planning and documentation.
Contrast these paths to front-end and back-end developers. QA engineers and QA analysts play vital roles in assuring software excellence, whereas developers primarily craft and shape the software itself.
Rising in the ranks as a QA engineer opens doors to leadership roles such as QA lead or QA manager, often culminating in the esteemed position of Director of Quality Assurance. This trajectory requires expertise, leadership, and an unwavering commitment to software quality.
