Radical works with some of the largest hospitals and public health programmes in India, and has a growing footprint both inside the country and abroad.
As a DevOps Engineer at Radical, you will:
Work closely with all stakeholders in the healthcare ecosystem - patients, doctors, paramedics and administrators - to conceptualise and bring to life the ideal set of products that add value to their time
Work alongside Software Developers and ML Engineers to solve problems and assist in architecture design
Work on systems which have an extraordinary emphasis on capturing data that can help build better workflows, algorithms and tools
Work on high performance systems that deal with several million transactions, multi-modal data and large datasets, with a close attention to detail
We’re looking for someone who has:
Familiarity and experience with writing working, well-documented and well-tested scripts, Dockerfiles, Puppet/Ansible/Chef/Terraform scripts.
Proficiency with scripting languages like Python and Bash.
Knowledge of systems deployment and maintainence, including setting up CI/CD and working alongside Software Developers, monitoring logs, dashboards, etc.
Experience integrating with a wide variety of external tools and services
Experience navigating AWS and leveraging appropriate services and technologies rather than DIY solutions (such as hosting an application directly on EC2 vs containerisation, or an Elastic Beanstalk)
It’s not essential, but great if you have:
An established track record of deploying and maintaining systems.
Experience with microservices and decomposition of monolithic architectures
Proficiency in automated tests.
Proficiency with the linux ecosystem
Experience in deploying systems to production on cloud platforms such as AWS
The position is open now, and we are onboarding immediately.
Please write to us with an updated resume, and one thing you would like us to see as part of your application. This one thing can be anything that you think makes you stand apart among candidates.
Radical is based out of Delhi NCR, India, and we look forward to working with you!
We're looking for people who may not know all the answers, but are obsessive about finding them, and take pride in the code that they write. We are more interested in the ability to learn fast, think rigorously and for people who aren’t afraid to challenge assumptions, and take large bets -- only to work hard and prove themselves correct. You're encouraged to apply even if your experience doesn't precisely match the job description. Join us.
