Job description

About Druva

We are building a modern standard with our cloud‑native solutions, designed to simplify the toughest challenges in cyber resilience for our customers. As a pioneer and market leader in fully managed SaaS data protection, we help organizations secure and recover their data from ransomware, cyberattacks, and operational disruptions without the complexity, cost, or risk of legacy infrastructure.

Our momentum is backed by the market: Druva was named a Leader in the 2025 Gartner® Magic Quadrant™ for Backup and Data Protection Platforms, a Leader in the 2025 IDC MarketScape for Cyber‑Recovery, and a Leader & Outperformer in the 2025 GigaOm Cloud Data Protection Radar. Customers validate that leadership every day through strong Gartner Peer Insights ratings, standout Net Promoter Scores (NPS), and top willingness‑to‑recommend results.

The Foundation team at Druva is responsible for designing a highly performant and scalable cloud file system on the Druva cloud in AWS. This file system is used to back up billions of files per day, translating to millions of metadata requests per second across regions. It leverages key concepts such as file system metadata, versioning, and eventual consistency, along with AWS services like S3, DDB, and Kinesis. A purpose‑built key‑value store manages these metadata requests. While the core file storage engine provides backup storage for all Druva products, allied components like the indexing engine, key‑value store, and big data pipeline provide scalable search, analytics, and compliance services. The team keeps track of newer services, storage tiers, and various aspects of existing AWS services to take advantage of the continuous evolution of services and use them effectively in the background.

As a Sr. Software Engineer in the filesystem team, you will provide technical ownership to create high‑quality software by designing and implementing features within the filesystem. This role requires excellent communication skills to collaborate with architects and other senior engineers to refine requirements and with product owners to drive features to completion with good quality.

Key Areas the Team is Working On

• Improving resiliency of the filesystem with periodic incremental consistency checks, both for petabytes of metadata and hundreds of petabytes of data residing in the cloud, including metadata versioning and change tracking.
• Third‑party secondary storage appliance integration for data centre data protection.
• Extending the filesystem to store a variety of workloads beyond files/folders, e.g., emails and messages.
• Optimising the filesystem for cost using strategies and algorithms to reduce cloud cost, such as leveraging cheaper cloud storage tiers and reducing IO requests.
• Developing tools that help debug production issues more efficiently.

Key Skills

• 6+ years of experience, preferably in a product company with exposure to storage architectures.
• Strong demonstrable experience in systems programming, especially in multithreading, synchronization, fault tolerance, and data consistency at scale.
• Hands‑on experience in the design and development of complex products.
• Extensive hands‑on experience in Go, Python, C, C++, or Java on Unix/Linux platforms.
• Strong understanding of complex concepts related to computer architecture, data structures, algorithms, design concepts, and programming practices.
• Experience in working with Service‑Oriented Architecture (SoA), especially in the service’s backend.

Desirable Skills

• Excellent written and verbal communication skills.
• Experience in Cloud Technologies (preferably AWS) will be advantageous.
• Working knowledge of Docker and Kubernetes will be an advantage.
• Working knowledge of storage and file systems, including file system consistency checks.
• Hands‑on experience using generative AI for codegen.

Role and Responsibilities

• The Sr. Software Engineer is the technical owner in building enterprise‑grade, scalable, performant systems that deliver the required functionality.
• Design and implement sufficiently large and complex features and/or architectural improvements to the product.
• Suggest and propose solutions to complex design problems.
• Identify areas of engineering improvements to the product and work with product architects and the team to address them.
• Technically guide junior engineers with feature design and implementation.
• Review the design and implementation done by junior engineers.
• Independently handle complex escalations and guide others as required.
• Write technical blogs and make technical presentations in internal and external forums.

Qualification

• B.Tech / B.E / M.E / M.Tech (Computer Science) or equivalent.
