🏢 About Our Client

Our client is a leading enterprise cybersecurity company offering an integrated platform for Digital Rights Management (DRM), Enterprise File Sync and Share (EFSS), and Content-Aware Data Protection (CDP). With patented technologies for secure file sharing, endpoint encryption, and real-time policy enforcement, helps organizations maintain control over sensitive data — even after it leaves the enterprise perimeter.

🎯 Role Overview

We are looking for a skilled Python Developer with a strong product mindset and experience building scalable, secure, and performance-critical systems. You will join our core engineering team to enhance backend services powering DRM enforcement, file tracking, audit logging, and file sync engines.

This is a hands-on role for someone who thrives in a product-first, security-driven environment and wants to build technologies that handle terabytes of enterprise data across thousands of endpoints.

🛠️ Key Responsibilities

●      Develop and enhance server-side services for DRM policy enforcement, file synchronization, data leak protection, and endpoint telemetry.

●      Build Python-based backend APIs and services that interact with file systems, agent software, and enterprise infrastructure.

●      Work on delta sync, file versioning, audit trails, and secure content preview/rendering services.

●      Implement secure file handling, encryption workflows, and token-based access controls across modules.

●      Collaborate with DevOps to optimize scalability, performance, and availability of core services across hybrid deployments (on-prem/cloud).

●      Debug and maintain production-level services; drive incident resolution and performance optimization.

●      Integrate with 3rd-party platforms such as LDAP, AD, DLP, CASB, and SIEM systems.

●      Participate in code reviews, architecture planning, and mentoring junior developers.

📌 Required Skills & Experience

●      3+ years of professional experience with Python 3.x, preferably in enterprise or security domains.

●      Strong understanding of multithreading, file I/O, inter-process communication, and low-level system APIs.

●      Expertise in building RESTful APIs, schedulers, workers (Celery), and microservices.

●      Solid experience with encryption libraries (OpenSSL, cryptography.io) and secure coding practices.

●      Hands-on experience with PostgreSQL, Redis, SQLite, or other transactional and cache stores.

●      Familiarity with Linux internals, filesystem hooks, journaling/logging systems, and OS-level operations.

●      Experience with source control (Git), containerization (Docker/K8s), and CI/CD.

●      Proven ability to write clean, modular, testable, and scalable code for production environments.

➕ Preferred/Bonus Skills

●      Experience in EFSS, DRM, endpoint DLP, or enterprise content security platforms.

●      Knowledge of file diffing algorithms (rsync, delta encoding) or document watermarking.

●      Prior experience with agent-based software (Windows/Linux), desktop sync tools, or version control systems.

●      Exposure to compliance frameworks (e.g., DPDP Act, GDPR, RBI-CSF) is a plus.

🌟 What We Offer

●      Work on a patented and mission-critical enterprise cybersecurity platform

●      Join a fast-paced team focused on innovation, security, and customer success

●      Hybrid work flexibility with competitive compensation and growth opportunities

●      Direct impact on product roadmap, architecture, and IP development
