Role Overview The Software Engineer (Backend) is responsible for the development, maintenance, and continuous improvement of backend systems supporting company products. This role applies solid object-oriented programming (OOP) principles, algorithmic problem-solving, and system design skills to build scalable, secure, and maintainable software. The engineer collaborates across teams to deliver reliable, high-quality solutions across distributed environments.

Core Competencies ● Object-Oriented Programming (OOP): Strong understanding of OOP principles, design patterns, and abstraction to create modular, reusable, and testable systems. ● Algorithms &

- Data Structures: Ability to apply algorithms and complexity analysis to build performant, optimized systems. ● Distributed Systems &
- Microservices: Familiarity with distributed, service-based architectures and an understanding of service contracts and observability. ● Authentication &
- Authorization: Understanding of secure authentication and access control models, including token-based and role-based strategies. ● System &
- API Design: Ability to contribute to backend architectures, RESTful and Graph QL APIs, and service integrations that balance performance and maintainability. ● Code Quality &
- Testing: Committed to producing clean, secure, and maintainable code supported by automated testing frameworks and CI/CD processes. ● Problem Solving &
- Root Cause Analysis: Able to diagnose issues across services and layers, identify root causes, and implement sustainable fixes. ● Collaboration &
- Communication: Works effectively across Product, Architecture, QA, and Support teams with explicit, proactive communication. ● Continuous Improvement: Demonstrates ownership in enhancing processes, tools, performance,



and code quality across the engineering lifecycle.

Responsibilities ● Develop and maintain backend systems, APIs, and integrations supporting company products and distributed services. ● Write clean, modular, and testable code in PHP and complementary technologies such as Java Script, HTML/CSS, and related frameworks. ● Contribute to distributed systems and microservices that support scalability, reliability, and separation of concerns. ● Apply OOP principles and solid architectural patterns to ensure extensibility and maintainability. ● Implement and maintain secure authentication and authorization mechanisms (e.g., OAuth2, JWT, RBAC). ● Utilize data structures, algorithms, and caching strategies to optimize system performance and responsiveness. ● Conduct debugging, profiling, and performance tuning across multiple environments and services. ● Collaborate with Product Managers, Architects, QA, and Support Teams to gather requirements, define scope, and ensure successful delivery. ● Participate in testing strategies with QA/QE teams to ensure coverage of both new and existing functionality. ● Adhere to code quality, security, and scalability standards across the development lifecycle. ● Participate in peer code reviews, contributing to knowledge sharing and consistent practices. ● Maintain technical documentation including API specifications and relevant implementation notes.



● Participate in engineering reviews, sprint ceremonies, and cross-team demos to align on progress and priorities. ● Ensure compliance with company policies regarding open-source usage and third-party dependencies.

Qualifications ● Bachelor's degree in Computer Science, Software Engineering, or related field, or equivalent professional experience. ● 3+ years of backend software engineering experience, primarily in PHP production environments. ● Solid understanding of OOP, design patterns, algorithms, and data structures. ● Experience building and maintaining backend systems and service integrations. ● Proficiency in secure API design and familiarity with authentication/authorization concepts. ● Experience with relational databases (My SQL, Postgre SQL) and backend architecture fundamentals. ● Familiarity with version control (Git), CI/CD pipelines, and containerized environments. ● Ability to debug, optimize, and deliver reliable solutions. ● Positive communication, collaboration, and documentation skills. ● Strong sense of ownership and accountability.

Preferred Skills ● Experience with modern PHP frameworks such as Laravel or Symfony. ● Familiarity with RESTful and Graph QL API design and frontend integration best practices. ● Experience with Dev Ops, container orchestration (Docker, Kubernetes), and cloud infrastructure (AWS, GCP, Azure). ● Knowledge of distributed caching, queuing, and messaging systems (e.g., Redis, Rabbit MQ, Kafka). ● Exposure to observability and monitoring tools (e.g., Prometheus, ELK Stack, Datadog, Open Telemetry). ● Understanding of asynchronous processing, event-driven systems, and service-to-service communication patterns.
