About Medflix - empowering healthcare professionals for better care

Medflix (www.medflix.app/app) is a platform where healthcare professionals (doctors, medical students and more) stay updated through live talks, Q&As, support material and more. Through the platform we believe that these professionals can be empowered to deliver better care to patients (like our families) throughout the globe.

In its current (and evolving) form, it is a live learning and engagement platform seeing tremendous week-on-week growth through stellar speakers and a very active early community. The product is in the growth stages and you will be playing a key role in steering the tech to create a scalable and lovable product experience.

We are backed by startup, VC and PE veterans including Kunal Shah (CEO, Cred), Raghunandan G (Zolve, ex-TFS), Avnish Mehra (Everstone) and more.

Medflix is a platform by PlexusMD (www.plexusmd.com/app), a network trusted and loved (4.4 stars on Playstore and 4.4 on Appstore) by more than 3 lakh doctors in India and working closely with leading healthcare providers and companies like AIIMS, Jaslok, Hinduja, Apollo, HCG, Elsevier, Association of Physicians of India, Indian Association of Cardio-thoracic surgeons, Society of Nuclear Medicine, Govt of Gujarat (HFW Dept), Govt of Haryana (SIFHW), McKinsey and company, Takeda, Mankind and others.

About the Role

Tech stack (expertise in all is not required, experience in some will be sufficient):

• React / Next.js (required, at least 1 year of experience)
• Express.js (required, at least 1 year of experience)
• Familiarity with cloud services (gcp / azure / aws)
• PostgreSQL (or expertise in any relational database)
• Redis
• Docker/Kubernetes deployment (good to have)

For this role we are looking for engineers with an entrepreneurial mindset, an understanding of how startups operate and who like to get their hands dirty when unknown things come their way. You will work closely with the product team to prioritise and ship features with a predictable cadence.

As this role is full-stack, you need to have a good understanding of frontend design and be obsessed with responsiveness and pixel-perfect behaviour. On the backend side, an OCD for efficiency and optimisation is a required personality trait.

Demonstrated history of solving hard problems (frontend/backend or both) is a great-to- have.

Benefits and growth

While we ensure competitive compensation (plus ESOP options for deserving candidates), at Medflix, you will also have a strong say in how final solutions look. You will get the opportunity to learn to steer an accelerating rocket ship.

College credentials, background or years of experience are no bar for growth inside the company for enthusiasts who believe in our mission and demonstrate that passion to create a product that healthcare workers love.
