The Software Engineer (SE-2) is a mid-level role for developers who have established a solid technical foundation and are ready to take on more complex tasks with greater independence. At this tier, engineers are expected to deliver medium-sized features end-to-end, contribute to technical discussions, and begin mentoring junior team members. SE-2 engineers play a crucial role in ensuring the quality and scalability of the software they develop while collaborating effectively within a team.

This role marks a transition from learning to contributing independently, with a growing focus on ownership, problem‑solving, and collaboration.

Key Responsibilities

- Independently design, develop, and deliver medium-sized features and components
- Troubleshoot and resolve moderately complex bugs, performance issues, and technical challenges
- Contribute to code reviews, providing detailed and constructive feedback to peers and junior engineers
- Follow and improve team coding standards, best practices, and software development workflows
- Write and maintain comprehensive unit tests and contribute to improving overall code coverage
- Document solutions, processes, and technical decisions for clarity and future reference
- Participate in technical discussions and contribute ideas for solving project challenges and improving processes
- Collaborate effectively with Tech Leads, product managers, designers, and QA engineers to clarify requirements and ensure feature delivery
- Mentor and assist junior engineers (SE-1 and interns), helping them improve their coding and debugging skills
- Learn and apply new technologies, tools, and frameworks as required by the team or project

Skills & Qualifications

- Proficiency in at least one programming language (e.g., JavaScript, Python, C#)
- Solid understanding of software development concepts:
- Data structures and algorithms
- Debugging and problem‑solving techniques




- Write clean, maintainable, and efficient code following SOLID principles and team best practices

- Experience working with relational and/or NoSQL databases (e.g., PostgreSQL, SQL Server, MongoDB)

- Experience implementing and maintaining CI/CD workflows (e.g., GitHub Actions)
- Familiarity with Agile methodologies (e.g., Scrum, Kanban) and tools like Jira, Azure DevOps
- Understanding of RESTful APIs, HTTP protocols, and basic architectural patterns
- Experience with version control systems, particularly Git
- 2-4 years of professional experience as a software developer
- Strong communication, collaboration, and problem‑solving skills
- Exposure to front‑end frameworks like React, Vue.js, or Angular

Additional Skills (Nice To Have)

- Experience optimizing software for performance, scalability, and reliability
- Familiarity with containerization tools like Docker or orchestration tools like Kubernetes
- Basic knowledge of security best practices for software development
- Contributions to open-source projects or personal coding projects
- Experience with React Native and mobile application development in general

Career Path Recommendations

- Taking ownership of increasingly complex and critical projects
- Developing deeper expertise in system design, architecture, and scalability
- Expanding proficiency with cloud platforms, CI/CD, and performance optimization
- Contributing to technical decision‑making and mentoring junior team members more actively

Evaluation Metrics

- Ability to deliver features with quality and growing autonomy
- Proficiency with databases, cloud platforms, and CI/CD tools
- Consistency in adhering to team processes, Agile practices, and coding standards
- Effective collaboration with Tech Leads, peers, and stakeholders
- Mentoring contributions and ability to help junior engineers grow
