What is a Software Development Engineer(SDE)?
A software development engineer (SDE) is tasked with building applications and software systems by applying principles from computer science, computer engineering, information technology, and analysis. Their role includes optimizing programs for better performance and modifying software based on client requirements.
Beyond coding, a software development engineer plans high-level aspects of applications, such as functionality and ways to reduce time and space complexity. Proficiency in algorithms and programming is essential.
To better understand an SDE’s role, let’s examine their responsibilities at a tech giant like Amazon:
- Contributing to the definition of security, scalability, and low-latency processes
- Collaborating with cross-functional teams to deliver on-demand projects
- Delivering and supporting multi-tiered software applications and tools
- Innovating new products for customers by working with fellow employees
SDE-1:
This is likely the first step in your tech career journey. Fresh computer science graduates or those with 1-2 years of experience usually start as an SDE 1. These candidates are expected to have a basic understanding of programming, a willingness to learn, the ability to follow instructions logically, and the capability to complete assigned tasks. Using Stack Overflow to find solutions is acceptable if they comprehend what they’ve copied and ensure the code is reviewed for compliance with existing styles. Following Standard Operating Procedures (SOPs) is a fundamental requirement.
Engineers typically begin this phase by developing test cases and fixing bugs—skills often not emphasized in universities. Problem-solving is a key strength they should possess. When errors occur, they need to identify them using tools or log messages, understand their causes, and collaborate with team members to resolve them. SDE-1s often need additional support from their senior colleagues to fulfill their responsibilities. In most product-based companies, an SDE-1 (or L1 SWE-2 at Google) mainly focuses on implementation tasks. They convert design documents from senior colleagues into production-ready code, which is why “production-ready code” is a common phrase in interviews. At a minimum, an SDE-1 should produce accurate and correct code.
Skills and Tools Used
- Programming Languages: Proficiency in one or more programming languages (e.g., Java, Python, C++, JavaScript).
- Version Control: Using version control systems like Git.
- IDEs and Text Editors: Working with Integrated Development Environments (IDEs) like Visual Studio Code, IntelliJ IDEA, or Eclipse.
- CI/CD Tools: Utilizing Continuous Integration/Continuous Deployment tools like Jenkins, Travis CI, or GitHub Actions.
- Testing Frameworks: Writing tests using frameworks like JUnit, pytest, or Jasmine.
- Communication Tools: Collaborating through tools like Slack, Microsoft Teams, or email.
- Project Management Tools: Tracking tasks and progress using tools like Jira, Trello, or Asana.
By following this process, an SDE 1 can effectively contribute to the software development lifecycle and grow into more advanced roles over time.

SDE-2:
This is a step up the tech career ladder, often filled by individuals with 2-4 years of experience. An SDE-2 is expected to have a solid grasp of programming concepts, demonstrate proficiency in software design, and take ownership of more complex tasks.
The candidate should not only understand and follow directions but also contribute to the decision-making process, providing insights and suggestions. While still referring to resources like Stack Overflow is acceptable, an SDE-2 should now be able to identify the nuances and implications of the solutions they find, ensuring adherence to best practices and existing code standards.
Responsibilities and Expectations
- Problem-Solving: Tackling more complex problems, debugging, and improving the efficiency and performance of the code.
- Code Quality: Ensuring code quality by writing comprehensive unit tests, performing code reviews, and following coding standards.
- Collaboration: Working closely with cross-functional teams, including product managers, designers, and other developers, to deliver high-quality products.
- Mentorship: Assisting and mentoring junior developers, helping them to understand and implement best practices.
- Design and Implementation: Contributing to the design phase and converting high-level design documents into production-ready code. SDE-2s are often involved in designing modules or features rather than just implementing them.
Skills and Tools Used
- Programming Languages: Advanced proficiency in one or more programming languages (e.g., Java, Python, C++, JavaScript).
- Version Control: Mastery of using version control systems like Git.
- IDEs and Text Editors: Expertise in using Integrated Development Environments (IDEs) like Visual Studio Code, IntelliJ IDEA, or Eclipse.
- CI/CD Tools: Proficient in utilizing Continuous Integration/Continuous Deployment tools like Jenkins, Travis CI, or GitHub Actions.
- Testing Frameworks: Advanced skills in writing tests using frameworks like JUnit, pytest, or Jasmine.
- Communication Tools: Effective collaboration through tools like Slack, Microsoft Teams, or email.
- Project Management Tools: Efficient tracking of tasks and progress using tools like Jira, Trello, or Asana.
Additional Responsibilities
- System Design: Contributing to high-level system design, including architectural decisions.
- Optimization: Identifying and implementing optimizations to improve system performance and scalability.
- Research: Staying updated with the latest industry trends and incorporating relevant technologies and practices.
By excelling in these areas, an SDE-2 can significantly impact the software development lifecycle and pave the way for more advanced roles, such as SDE-3 or technical lead positions.
