SDE 3

Job Summary:

As an SDE3, you will be a technical leader within your team, responsible for driving the design

and implementation of complex software systems. You will play a crucial role in shaping our

technical roadmap, mentoring junior engineers, and ensuring the delivery of high-quality, scalable,

and maintainable code. This role requires deep technical expertise in both PHP and Python, a

strong understanding of architectural patterns like MVC, and proficiency with modern web

frameworks and database technologies.

Key Responsibilities:

● System Design & Architecture: Lead the design and architecture of highly scalable,

reliable, and performant backend systems and microservices. Make informed technical

decisions, considering trade-offs and long-term system health.

● Full-Stack Development (Backend Focus): Develop robust and efficient backend

solutions using PHP and Python.

○
PHP:
Design and implement complex features leveraging PHP, with a strong

emphasis on MVC (Model-View-Controller) architectural patterns to ensure

modular, maintainable, and scalable code.

○
Python:
Develop high-performance APIs and services using Python, with

demonstrated proficiency in either Flask or FastAPI.

● Database Management: Design, optimize, and manage database schemas for both SQL

(e.g., MySQL, PostgreSQL) and NoSQL (e.g., MongoDB, Redis, Cassandra)

databases. Optimize complex queries and ensure data integrity and performance.

● Technical Leadership & Mentorship: Provide technical guidance, conduct thorough

code reviews, and mentor SDE1 and SDE2 engineers, fostering their growth and ensuring

adherence to best practices.

● Code Quality & Best Practices: Champion clean code principles, test-driven

development (TDD), and continuous integration/continuous deployment (CI/CD)

practices. Identify and address technical debt proactively.

● Problem Solving & Debugging: Independently analyze, troubleshoot, and resolve

complex technical issues across various layers of the application.

● Cross-Functional Collaboration: Collaborate closely with product managers, QA

engineers, and clients to translate business requirements into technical solutions and

deliver features effectively.

● Performance & Optimization: Identify performance bottlenecks and implement solutions

to optimize system response times, resource utilization, and overall scalability.

Qualifications:

● Bachelor's or Master's degree in Computer Science, Software Engineering, or a related

field.

● 5-7 years of progressive experience in software development, with a significant portion in

backend development.

● Proficiency in PHP, with extensive experience in designing and implementing

applications adhering to the MVC architectural pattern.

● Expert proficiency in Python, with hands-on experience and a strong understanding of

either Flask or FastAPI for building robust web services and APIs.

● Demonstrable strong knowledge of SQL databases (e.g., schema design, query

optimization, indexing, stored procedures) and experience with at least one relational

database system (e.g., MySQL, PostgreSQL).

● Strong knowledge of NoSQL databases (e.g., document stores like MongoDB, key

value stores like Redis, or column-family stores like Cassandra), including data modeling,

querying, and performance considerations.

● Experience with version control systems, particularly Git.

● Solid understanding of data structures, algorithms, and object-oriented programming

(OOP) principles.

● Excellent problem-solving, analytical, and debugging skills.

● Strong communication and interpersonal skills, with the ability to articulate complex

technical concepts to both technical and non-technical audiences.

Preferred Skills:

● Experience with cloud platforms (e.g., AWS, Azure, GCP, MediaLive).

● Familiarity with containerization technologies (Docker, Kubernetes).

● Experience with message queues (e.g., RabbitMQ, SqS).

● Knowledge of front-end technologies (JavaScript,HTML, CSS) is a plus.

● Experience working in an Agile/Scrum development environment.
