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. To build this petabyte-scale, distributed,
services-oriented cloud file system, various key concepts like file system
metadata, versioning, and eventual consistency are used along with leveraging
various AWS services like S3, DDB, and Kinesis. A purpose-built key-value store
is used for managing these metadata requests.  While the core file storage
engine provides the backup storage for all the Druva products, allied components
like the indexing engine, key-value store, and big data pipeline provide
scalable search, analytics, and compliance services. The team diligently 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 be providing
technical ownership to create high-quality software by owning the design and
implementation of features within the filesystem. This role will require
excellent communication skills as you will collaborate with architects and other
senior engineers to refine requirements, and other product owners to drive
features to completion with good quality. 

Some of the 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.  Metadata versioning and change tracking.
* Third-party secondary storage appliance integration for data centre data
protection.
* Extend the filesystem to store a variety of workloads beyond files/folders,
e.g., emails and messages
* Optimise the filesystem for cost using  strategies and algorithms to reduce
cloud cost  (eg. leveraging cheaper cloud storage tiers and reducing IO
requests)
* Develop tools that help debug production issues more efficiently

Key Skill

* 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++/Java on Unix/Linux
platforms.

A strong understanding of complex concepts related to computer architecture,
data structures, algorithms, design concepts, and programming practices.

* Experience in working with SoA (Service-oriented Architecture), 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's role is to be the technical owner in building
enterprise-grade, scalable, performant systems which deliver the required
functionality 
* Should be able to 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.
* Should be able to technically guide junior engineers with feature design and
implementation.
* Review the design and implementation done by junior engineers.
* Should be able to independently handle complex escalations and guide others
as required.
* Be able to 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
