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 Title: Tech Team Lead – Flutter

Department: Engineering

Location: Surat / Ahmedabad (On-site)

Employment Type: Full-time

About the Company

We are an AI-driven nutrition platform built to make healthier eating and living effortless. We translate ingredients and dishes into reliable nutrition profiles, then personalize recommendations based on goals, context, and preferences—across home cooking, daily routines, and restaurant ordering.

Our technology includes Flutter mobile apps, a Python/Django API, real-time data services, and machine learning models for tagging, ranking, and predictions. We’re building a delightful, safe, and scalable experience that helps users choose better meals and track progress—with strong standards for privacy, quality, and performance.

Role Summary

As the Tech Team Lead, you will lead a cross-functional engineering squad (Flutter, Backend, QA, and occasionally Data) to deliver secure, scalable product features on predictable timelines. This role combines hands-on architecture and coding with team leadership, agile execution, and quality ownership.

You’ll mentor engineers, improve engineering practices, and collaborate closely with Product and Design teams to ship impactful, user-centric experiences.

Key Responsibilities

• Own squad roadmap delivery — break down epics into milestones, estimate efforts, prioritize, and ensure timely releases.
• Provide technical leadership — define architecture, enforce coding standards, and guide trade-offs between performance, cost, and complexity.
• Contribute 30–50% hands-on coding — review critical PRs, pair program, and work on key modules.
• Ensure quality and reliability through robust testing (unit/integration/E2E), CI/CD gates, observability, and incident management.
• Mentor and manage 4–8 engineers — conduct 1:1s, set goals, and drive performance and career growth.
• Maintain security and compliance — apply secure development best practices (AuthN/AuthZ, PII handling, secret management).
• Collaborate with Product/Design on scope and acceptance criteria; communicate status, risks, and dependencies effectively.
• Keep technical documentation up to date — architecture decisions, system diagrams, runbooks, and release notes.

Required Qualifications

• 6–9+ years of software engineering experience, with at least 2–3 years in team/squad leadership.
• Strong backend expertise in Python, Django/DRF, REST API design, caching, queues, and WebSockets.
• Working knowledge of Flutter/Dart architecture and state management to lead cross-stack initiatives.
• Experience with CI/CD (GitHub Actions, Fastlane, Codemagic), containers (Docker), and AWS (EC2/ECS/ECR, S3, CloudFront, CloudWatch).
• Strong testing culture using PyTest, Flutter Test, and observability tools (logs, metrics, tracing, alerts).
• Excellent estimation, prioritization, and communication skills, with the ability to challenge scope when necessary.

Preferred (Nice to Have)

• Experience releasing and managing mobile apps (Play Console, App Store Connect, TestFlight).
• Exposure to Data/ML pipelines (batch vs. real-time inference, model versioning).
• Familiarity with security practices — OWASP, IAM, secret management, VPCs.
• Domain experience in health-tech or food-tech, or other privacy-sensitive industries.

Tech Stack You’ll Work With

• Mobile/Web: Flutter (Dart), React (optional)
• Backend: Python, Django/DRF, Celery, Redis, WebSockets
• Data/Storage: PostgreSQL/MySQL, MongoDB
• Infra/DevOps: AWS (EC2/ECS/ECR/S3/CloudFront/CloudWatch), Docker, Nginx, GitHub Actions, Fastlane, Codemagic
• Quality/Observability: PyTest, Flutter Test, Playwright/Cypress, Sentry, Crashlytics, OpenTelemetry (optional)
