Employment Type: Full-time

Employment Agreement: Minimum 3 years (At the completion of 3 years, One Time Commitment Bonus will be applicable based on performance)

🏢 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

What will be your key responsibilities?

Although it’s an engineering role, you will have significant involvement in product, hiring and business as well. You may expect following key responsibilities:

Engineering: You’ll need to write code – a lot of code. At the end of the day, your most important responsibility is to get your company’s product to market and maximize the number of product experiments that can be run. You’ll make key architectural decisions that will be pillars of the engineering organization for years to come. At the same time, you’ll have to make serious trade-offs to balance speed of execution with quality.

Product: As a founding engineer, you’ll also have a significant amount of ownership over the product direction. You should expect to spend time talking to customers, teasing out use cases, and making prioritization decisions regarding both the short- and long-term roadmap. In many cases, you will be building features in the absence of any formal product requirement document.

Support: You should also expect to spend a fair amount of time in the trenches supporting customers. You’ll probably find yourself engaging with customers in shared Slack channels, WhatsApp groups etc.

Hiring: As a founding engineer, you will spend a ton of time sourcing, interviewing, and closing early team members. 

Business: Finally, you’ll gain exposure to all other aspects of the business – from fundraising, to sales, and beyond. Although you probably won’t be closing deals or making pitch decks, you will certainly be expected to sell your product and pitch the company’s vision.

How do you know you are right fit for the role?

• You have at least 2-4 years of experience. You are proficient with most of the following languages/frameworks:
• NodeJS
• AWS
• Databases (both SQL and NoSQL)
• You crave ownership. If you often find yourself raising your hand to own things end-to-end, you will likely really enjoy the ownership afforded to you as a founding engineer.
• You’re okay with ambiguity. You won’t get product requirement documents or designs for everything you’re expected to build. A stellar founding engineer will know when to ask for clarity and when to make educated assumptions. If you tend to gravitate towards more loosely scoped projects, that’s a good indicator that you’ll do well in this type of role.
• You’re multidisciplinary. A typical day might include anything from several hours of coding, to a few customer conversations, to a technical brainstorm or architecture discussion, to an interview or two. 

• You operate at light speed. A great founding engineer should welcome this challenge and thrive under the pressure of intense deadlines. 

What will be the hiring process?

• 2 round of technical interviews
• 2 round of behavioural interview

What will be your compensation?

• Review business requirements, identify gaps, and assist in authoring functional design documents.
• Analytical mind with problem-solving aptitude.
• Proactive and self-starter requiring minimal supervision, who can collaborate with multiple stakeholders in the company.
• Proficiency in relational databases like MySQL, MS SQL Server, and/or Oracle and web servers like IIS/Apache.
• Knowledge of cloud technologies (AWS, Azure, Google cloud), container, and virtualization will be a big plus.
• Familiarity with Continuous integration (Jenkins/Hudson), automated testing, and version control (GitHub, SVN).
• Knowledge of 3 rd party libraries and APIs, modern frameworks and design patterns, and test automation tools for Unit and Performance testing.
• Awareness of secure coding practices and standards.
• Knowledge of Single-Sign-On using OAuth 2.0/SAML/OID/JWT would be a definite plus. Above all, you should love to build and ship products that real people use every day!
