Senior Software Engineer (ReactJS+RoR)

Position Name : Senior Software Developer (Node.js/RoR/Swift/React)

Experience : 5 to 10 Years

📍 Location : Remote

Notice Period : Immediate to 15 Days

Role Overview :

We are looking for a highly skilled Senior Software Developer with expertise in Node.js, Ruby on Rails (RoR), React, and Swift.

The ideal candidate should have strong problem-solving skills, hands-on development experience, and a deep understanding of software architecture, design principles, and TDD best practices.

Key Responsibilities :

• Backend-Heavy Full-Stack Development : Strong focus on Ruby on Rails (RoR) for backend and React for frontend.
• Test-Driven Development (TDD) : Follow TDD principles to ensure high-quality code.
• Software Architecture & Design : Implement scalable and maintainable solutions.
• Data Structures & Algorithms : Optimize performance and ensure efficient solutions.
• Clean Code Practices : Write modular, reusable, and well-documented code.
• Agile Development : Work in an Agile environment with CI/CD pipelines.
• Full-Stack Ownership : Manage both backend and frontend development, including deployment.
• Peer Collaboration : Participate in code reviews, pair programming, and knowledge sharing.

Technical Skills & Experience :

Must-Have :

• Ruby on Rails (RoR) - Backend
• React.js - Frontend
• Strong expertise in architecture, design, and hands-on development.
• Excellent understanding of Data Structures & Algorithms.
• Proven experience with TDD principles.
• Excellent communication skills.

Good to Have :

• Experience with Node.js, TypeScript, Swift, and JavaScript
• Familiarity with relational databases and web frameworks
• CI/CD tools like Jenkins, Hudson, or Bamboo.

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

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. 

Job Summary: We are seeking a highly skilled Full-stack Developer to join our dynamic team as a Delivery Module Lead. The ideal candidate will possess strong expertise in Python and front-end technologies, enabling them to design, develop, and maintain robust web applications.

What you’ll work on

• Build features from end to end. Translate product requirements into working interfaces, backend services and database changes, and follow them through testing and release.
• Create responsive web experiences. Develop reusable React and Next.js components, connect them to APIs, and handle forms, loading states, errors and accessibility across screen sizes.
• Develop dependable APIs. Build modular Node.js services with NestJS, Fastify and related frameworks, with clear contracts, input validation, authentication, authorization and consistent error handling.
• Design and improve data models. Work with PostgreSQL and MySQL for relational data, MongoDB for document models and Neo4j for connected data. Write efficient queries, use appropriate indexes and manage schema changes carefully.
• Integrate systems and workflows. Connect third-party services and internal APIs, manage asynchronous operations, and account for failures, retries and data consistency.
• Make quality part of delivery. Write meaningful unit and integration tests, review code, reproduce bugs and document API behavior and technical decisions.
• Improve performance and security. Investigate slow pages and queries, troubleshoot service errors, and apply secure coding practices to protect application data.
• Work closely with the team. Discuss trade-offs with designers and developers, break work into manageable tasks, and communicate progress and blockers clearly.

• Comfort with Git, code reviews, debugging and testing your work before handing it over.
• A practical approach to problem-solving, willingness to learn and ownership of the features you build.

Bonus skills

Helpful experience, rather than prerequisites for applying.

• CI/CD pipelines: Automating builds, checks, tests and deployments, working with environment-specific configuration, and understanding release and rollback workflows.
• Jenkins: Creating or maintaining Jenkinsfiles, organizing pipeline stages, handling credentials securely and diagnosing failed builds.
• AWS: Deploying or supporting applications using services such as EC2, S3 and RDS, with awareness of IAM permissions, networking and CloudWatch logs.
