software engineer in test
A Software Engineer in Test (SET), often called a Software Development Engineer in Test (SDET), is a dual-focused professional who applies advanced software engineering principles to develop and implement automated testing tools and frameworks. After 14 years in this field, an individual is a seasoned expert who not only finds bugs but designs the robust systems that prevent them from occurring in complex, enterprise-level software.
The Role and Responsibilities
With 14 years of experience, an SET's work goes far beyond manual testing or simply using automation tools like Selenium or Cypress. The key aspects of the work include:
- Development:Designing and building comprehensive test automation frameworks from scratch using programming languages .
- Infrastructure & CI/CD:Integrating tests into the continuous integration/continuous deployment (CI/CD) pipelines, ensuring tests run automatically as part of the build and deployment process(Jenkins).
- Technical Problem Solving: Possessing deep analytical skills to not only identify a bug but to trace its cause through the codebase, often collaborating with development teams to find solutions.
- System Design & Architecture:Understanding the entire software development lifecycle and contributing to the design process to ensure testability and quality are baked in from the start.
- Risk Assessment: Applying experience to prioritize testing efforts based on risk, ensuring critical features are thoroughly vetted.
Software Developer Jr
As a Software Developer with 1 year of experience, you're past the absolute beginner stage, comfortable with core tasks like writing and debugging code, using Git, and working in Agile teams (stand-ups, sprints). You're expected to handle smaller features or bug fixes independently, learn quickly from seniors, contribute to the whole Software Development Lifecycle (design, code, test, maintain), and show strong problem-solving skills, adaptability, and teamwork. You're basically a solid junior dev, building on your foundational knowledge and focusing on practical application and growth.
What You're Doing (Day-to-Day)
- Coding & Debugging:Writing features, fixing bugs, writing unit tests.
- Collaboration: Daily stand-ups, planning, brainstorming with designers/engineers, code reviews.
- Tools: Using version control (Git) and contributing to Agile/Scrum processes.
- Maintenance: software keeps working, documenting your work.
Key Focus for Growth
- Understand the "Why": Learn how systems are built, not just what to type (e.g., design patterns, concurrency).
- Code: Study open-source projects to see best practices in action.
- Questions: Lean on senior devs for complex issues; it's expected.
