In the world of software engineering, there are various levels and titles that signify different levels of experience and responsibilities. Two common roles are Software Development Engineer 1 (SDE-1) and Software Development Engineer 2 (SDE-2). In this technical blog post, we will explore the key differences between these roles, the responsibilities they entail, and provide insights into how to progress from SDE-1 to SDE-2.
Role Overview Link to heading
Software Development Engineer 1 (SDE-1) Link to heading
SDE-1 is an entry-level position where engineers begin their professional journey. At this level, engineers are expected to have a solid foundation in software development concepts, programming languages, and problem-solving skills. They work closely with their team members and contribute to the development and maintenance of software applications.
Software Development Engineer 2 (SDE-2) Link to heading
SDE-2 is a mid-level position that requires a higher level of expertise and experience compared to SDE-1. Engineers at this level are expected to have a deeper understanding of software engineering principles, design patterns, and best practices. They take on more complex technical challenges and have a greater level of autonomy in their work. SDE-2s often mentor junior engineers and provide guidance to help them grow.

As an SDE-2, your responsibilities expand, including:
- Architectural design: You will contribute to the overall system architecture and design decisions, considering scalability, performance, and maintainability.
- Technical leadership: You will take ownership of complex features or projects, providing technical guidance and mentoring junior engineers.
- Code quality and best practices: You will advocate for code quality, enforce best practices, and drive initiatives to improve the development process.
- Cross-team collaboration: You may collaborate with other teams, such as product management or quality assurance, to align technical requirements and ensure successful project delivery.
Interviews: SDE-1 vs. SDE-2 Link to heading
SDE-1 Interviews Link to heading
For an SDE-1 position, the interview process typically focuses on assessing fundamental coding skills, problem-solving abilities, and technical knowledge. The interviews may include coding exercises, data structure and algorithm questions, and discussions on basic software engineering concepts. The goal is to evaluate your ability to apply core principles to solve problems efficiently and write clean, maintainable code.

As you progress to the SDE-2 level, the interview process becomes more challenging and comprehensive. Along with coding skills, the focus expands to assess your architectural and design capabilities, system scalability considerations, and ability to lead and mentor other engineers. You may encounter more complex coding exercises, design discussions, and behavioral interviews that evaluate your leadership potential and collaboration skills.
The SDE-2 interviews aim to gauge your readiness to handle higher-level responsibilities, drive technical decisions, and contribute to the overall success of the team and the organization.
Interaction with Product Managers Link to heading
SDE-1 Interaction Link to heading
As an SDE-1, your interaction with product managers typically involves understanding and implementing the features and functionalities specified by the product requirements. You will collaborate closely with the product manager to clarify requirements, provide technical insights, and ensure alignment between the product vision and the implementation.
Your role is primarily focused on executing the technical aspects of the product roadmap, while relying on the guidance and decision-making of the product manager to define the overall product direction.
SDE-2 Interaction Link to heading
As you transition to an SDE-2 role, your interaction with product managers becomes more strategic and collaborative. You are expected to provide valuable input in product discussions, contribute to feature ideation and planning, and offer technical expertise to shape the product roadmap.
You may have more influence over the product direction and be involved in higher-level discussions on prioritization, feasibility, and technical trade-offs. Your experience and understanding of the product domain allow you to provide valuable insights and help drive the product’s success.
Interaction with Engineering Managers Link to heading

As an SDE-1, your interaction with engineering managers focuses on receiving guidance, support, and mentorship. Engineering managers provide technical guidance, help prioritize tasks, and ensure you have the necessary resources to succeed in your role. They assist in your professional growth, provide feedback on your performance, and help you develop the skills needed to excel in your career.
SDE-2 Interaction Link to heading
As an SDE-2, your interaction with engineering managers evolves to a more collaborative and strategic level. You may work closely with engineering managers to define technical strategies, contribute to team planning and execution, and provide insights on resource allocation and team dynamics.
Engineering managers at this level rely on your expertise and leadership skills to drive technical initiatives, mentor junior engineers, and contribute to the overall success of the engineering organization.
Roadmap to Getting Promoted from SDE-1 to SDE-2 Link to heading
Progressing from SDE-1 to SDE-2 requires dedication, continuous learning, and expanding your skill set. Here is a roadmap to help you navigate the journey:
- Master core programming skills: Strengthen your programming skills and deepen your understanding of data structures, algorithms, and object-oriented design principles. Practice solving coding problems and challenges regularly.
- Gain domain knowledge: Become an expert in the domain your team operates in. Understand the business requirements and challenges to provide valuable technical solutions.
- Take ownership: Show initiative and take ownership of tasks and projects. Demonstrate your ability to work independently and deliver high-quality results.
- Collaborate effectively: Develop strong collaboration skills, communicate effectively with team members and stakeholders, and contribute actively to discussions and decision-making processes.
- Mentor and guide: Share your knowledge and mentor junior engineers. Help them grow and develop their skills.
- Expand technical expertise: Invest time in learning new technologies, frameworks, or tools that are relevant to your work. Stay updated with industry trends and emerging best practices.
- Contribute to the team: Take on additional responsibilities, such as leading initiatives, contributing to process improvements, or participating in cross-functional projects.
