1. Responsibilities Of An Entry-level Software Developer

Assisting the development team with all facets of software design and coding is the role of entry-level Software Developers, also known as Junior Software Developers. Some of their main responsibilities include learning the code base, participating in design meetings, writing simple code, addressing bugs, and helping the Development Manager with all design-related software developer job duties.

2. Responsibilities Of A Mid-level Software Developer

Mid-level programmers, unlike entry-level developers, do not require much aid or supervision. They are capable of doing everything alone and have additional responsibility because they have a thorough understanding of the code and technologies used in the projects.

For instance, if a Junior developer's primary focus is to develop a code that works, mid-level developers need to ensure that the code is up to the company's quality standards, clearly understandable, and fulfills all the project objectives. Mid-level programmers mostly write the majority of the code base for any software.

3. Responsibilities Of A Senior-level Software Developer

The following are the responsibilities of a Senior-level Software Developer: 

• Create high-quality software architecture and design 
• Identify, prioritize and carry out tasks across the software development life cycle 
• Create tools and applications by developing clean, efficient code 
• Utilize tools and programming to automate tasks 
• Code review and debugging 
• Conduct validation and verification tests
