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

- Familiarity and experience with writing working, well-documented and well-tested code in at least two of the following: React/Redux (preferred), NodeJS (preferred), Golang and Python
- Proficiency in the features of the language they are using, with knowledge of standards and best practices (Eg: ES2015 and above, Python 3.5 and above, React Hooks/HOC/Redux)
- 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:
- An established track record of building systems from scratch
- 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
- Experience in TypeScript

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: it can be an interesting hobby project that you’ve self-hosted, a research paper that’s been published, a collection of blog posts you’ve written, a repository you maintain, or your contributions to a major library.
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.
