As a Principal Backend Engineer, you will be responsible for architecting and guiding the development of robust, scalable, and secure backend systems. You'll play a strategic role in technical decision-making, mentor engineering teams, work closely with product and client-facing stakeholders, and drive adoption of modern technologies including AI/ML where relevant.

Key Responsibilities

Backend Architecture & Development

Own and evolve backend architecture across PHP (CodeIgniter/Laravel), Node.js services. Design and review scalable systems using microservices or modular monoliths. Manage integration across relational (MySQL) and non-relational (MongoDB) databases with optimal indexing, performance, and data modeling.

Technical Leadership

Lead design reviews, code quality checks, and establish backend development standards. Guide mid/senior engineers on best practices, CI/CD pipelines, and testing frameworks. Make critical decisions on refactoring legacy systems and modernizing platforms.

Client & Stakeholder Communication

Act as a technical point of contact for clients for backend architecture and integrations. Translate client/product needs into technical execution plans and communicate trade-offs. Present PoCs or explain complex backend workflows to non-technical stakeholders.

AI & ML Integration (Optional/Strategic)

Identify potential areas in backend or client systems to leverage AI (e.g., personalization, recommendations, fraud detection, data cleaning). Collaborate with data teams to design backend APIs or cron jobs that interact with AI models. Stay updated with practical AI APIs, tools (e.g., OpenAI, Langchain), and their integration points.

Scalability, Security & Performance

Perform regular audits on security, API rate-limiting, and role-based access. Optimize performance using caching, query optimization, job queues, etc. Plan for horizontal/vertical scaling on cloud infrastructure (AWS, GCP, etc.).
