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. 

About the Role

We are looking for an ambitious Software Engineering Intern to join our engineering team. You will write production-ready code, collaborate directly with senior engineers, and build features used by real users from day one. High performers will be considered for a full-time Pre-Placement Offer (PPO) at the end of the internship.

Key Responsibilities

• Build and maintain clean, scalable frontend or backend features under senior mentorship.
• Write modular, testable code and assist in unit testing and bug fixing.
• Collaborate with product managers, designers, and peers in an agile, fast-paced environment.
• Participate in code reviews, tech discussions, and sprint planning.

What We Are Looking For

• Strong grasp of data structures, algorithms, and core object-oriented/functional programming principles.
• Hands-on experience with at least one programming language (e.g., JavaScript/TypeScript, Python, Java, or Go) through personal projects, coursework, or open-source contributions.
• Working knowledge of REST APIs and relational or NoSQL databases (e.g., PostgreSQL, MongoDB).
• Basic familiarity with Git and version control workflows.
• Strong problem-solving mindset, fast learning ability, and genuine curiosity about software engineering.

What you will do:

● Design and build features for our web applications — front end and back end, using Ruby on Rails, Python, JavaScript, and React

● Work across the stack: databases, APIs, and the plumbing that connects them

● Take a feature from first line to shipped — you'll touch every phase of the build, not just one slice of it

● Test for performance, security, and the edge cases that actually break things in production

● Work directly with the rest of the team on shared infrastructure, not off in a corner

● Push for better tools and approaches as the codebase grows, instead of settling for "it's always been done this way

What you need 

 ● 0-1 years of professional experience building with Ruby on Rails, Java, Python, JavaScript/React, or Node

● Comfortable with JavaScript, HTML, CSS, and jQuery on the front end

● A real grip on data structures and algorithms — not just the interview-prep version

● Solid object-oriented design instincts

● You'd rather write simple, clean code than clever code

● Comfortable with relational databases day-to-day

● Working knowledge of NoSQL is a plus, not a requirement

● Some interest in the math and stats side of finance helps — you don't need to be an expert.

Also running in production here — OPTIONAL / NICE TO KNOW You won't be hired against this list. Prior exposure is a genuine plus, and you'll bump into these once you're in — but not knowing them isn't a blocker.

● Rust — pricing & risk engines

● Go — auth & billing services

● AWS Lambda

● API Gateway

● Redis

● DynamoDB

● CI/CD pipelines
