Hiring For
Front-End Engineer - I / II / III
Radical is a platform connecting data, medicine and people -- through machine learning, and usable, performant products. Software has never been the strong suit of the medical industry -- and we are changing that. We believe that the same sophistication and performance that powers our daily needs through millions of consumer applications -- be it your grocery, your food delivery or your movie tickets -- when applied to healthcare, has a massive potential to transform the industry, and positively impact lives of patients and doctors. 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 Full Stack 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
- Write code on the front-end, the back-end and anything it takes to solve the problems and delight users both internally and externally
- Build 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

- Knowledge of databases, and familiarity with REST API patterns
- 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:

- 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.

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.
