Software Engineer Levels In Big Tech Companies

Software Engineer Levels In Big Tech Companies

Software engineer levels typically range from software developer level 1 to software engineering manager level 5 in big tech companies. Entry-level work on small projects. Midlevel designs and implements new or modifies existing ones. Senior-level usually lead teams of developers.

Software Developer-Level 1

Software developer-level 1 (SD1) is the entry-level position for software developers in big tech companies. Candidates who hold this designation typically have a college degree in computer science or a related field and can write code using object-oriented programming languages.   

Developers do:

  • Working on basic applications such as databases, websites, app stores, or contact forms
  • Collaborating with other team members to develop features
  • Resolving customer issues

Other responsibilities include creating user interfaces, designing database structures, implementing algorithms, creating test cases and performing quality assurance checks on their projects, and optimizing software performance. In addition to coding tasks, they are responsible for documenting their work so that other team members can understand it better. 

They may also be required to participate in team meetings and provide feedback on project updates or bug fixes. Increasingly, they are expected to contribute their skills to expanding company products by taking on new challenges and tasks that fall outside their traditional role descriptions.

If you’re looking to develop your career in technology consulting or start your own tech business, then becoming an SD1 may be a good starting point. However, keep in mind that there is competition for these positions across the globe so don’t let anyone tell you otherwise – hard work does pay off.

Software Developer-Level 2

A software developer level 2 (SD2) is a mid-level position in software companies. This designation would typically be held by individuals who have eight or more years of experience coding and designing web applications. 

Roles and responsibilities include:

  • Developing new applications or features using object-oriented design patterns and other programming languages.
  • Creating, testing, and maintaining modules of existing software.
  • Debugging programs to find and fix errors.
  • leading and participating in code reviews
  • architecting solutions
  • developing test scripts
  • mentoring other developers on their team
  • managing complex projects from conception to delivery
  • maintaining source control systems.
  • Contributing code changes to a team’s source control system (Git, Mercurial).

You will be researching new technologies, writing efficient code using best practices, and debugging errors no matter how small they might seem. Your time at this level should be spent learning as much as possible so that you can improve both your skills and your career prospects. In addition, being well-versed in different programming languages will give you an edge when it comes to finding future employment opportunities within the industry.

Software Developer-Level 3

At a software developer level 3 (SD3), you will likely be working on high-level and complex systems that are used to serve the business. As such, you may be responsible for developing application logic and designing user interfaces. You should expect to spend a large chunk of your time writing code and debugging it so that it meets the required functional specifications. 

You must also have strong technical skills in at least one programming language(s), which makes coding difficult problems very quickly. In some cases, you might also need to work with other departments such as marketing or sales to create an effective customer experience.

Your main tasks may include:

  • Designing and developing application components
  • Updating/maintaining application codes according to design specifications
  • Maintaining project timelines
  • Working with other software developers within the organization
  • Developing user manuals and training materials.
  • Contribute ideas/suggestions to improve productivity/procedures across different areas of an organization.

SDL 3 Other Responsibilities 

It includes:

  • Develops business logic using object-oriented design principles, with emphasis on modeling, testing, and debugging. 
  • May work concurrently with architects to create explicit user stories or use cases that can then be mapped into a system architecture.
  • Uses an integrated development environment (IDE) to develop code manually or through automated scripts. 
  • Has deep knowledge of related libraries and frameworks used for software development within a company’s technology stack.
  • Regularly reviews code against preplanned tests and evaluate changes based on their impact on compliance with specified requirements laid down by management/ownership group(s).

Finally, being able to quickly understand larger system design issues is essential for success in this role.

Software Developer-Level 4 And Level 5

As a software developer level 4, you will be developing large and complex applications. You may also provide front-end design, back-end development, or other related services.

Software developer-level 4 (SD4) often do: 

  • designing, developing, testing, and maintaining the end-user interface (UI), application development life cycle management (ADLC), back-end architecture, cloud computing services, and applications design. 
  • Building web applications using HTML/CSS/JS
  • working with databases such as MySQL or MongoDB
  • Architecting APIs for access by other systems or devices
  • managing project deadlines and resources effectively.

Software developers at level 5 (SD5) in big tech companies will be developing and delivering high-quality code that meets the business requirements of the company. They typically work with other team members to design, test, deploy, and optimize applications.

More About Software Developer-Level 5

As an SD5 in a big tech company, you should be proficient in multiple programming languages and tools. You should also have experience working on large-scale projects and understand how to use automated testing frameworks like unit tests or integration tests. In addition to coding skills, you must also be familiar with agile methodologies such as Scrum or Kanban so that your development processes are aligned with customer goals.

You may also need advanced knowledge of marketing automation tools such as market research surveys or lead gen forms processing scripts. And lastly, you will need excellent problem-solving skills to identify defects and fix them quickly before they affect users’ experiences with the application.


We have highlighted important skills and knowledge that you need to have and summarized some of the most important points that you might want to know if you’re looking to embark on this rewarding software engineering career journey.
