We're hiring – Senior Full-Stack Developer

Chennai, Tamil Nadu, India KERA C Full time

I'm looking for a senior-level full-stack developer to join me full-time and take the lead on software development across two projects.

Both are already prototyped (POC) and ready to be industrialized.

About the Projects

Project 1: Fitness × Gaming Mobile App

A cross-platform mobile app that connects real-world strength training (reps, sets, volume, intensity) with a digital progression system linked to video games and virtual avatars.

This is not another gamified fitness app – it's a bridge between the physical world and real gaming universes.

The app will integrate with a dedicated smart device (under separate hardware development by another team).

Your scope:

  • You do not handle the hardware or firmware
  • You will work on Bluetooth/data integration, back-end processing, and mobile UX

Project 2: Lean / Operational Excellence Web Platform

A SaaS platform for businesses to:

  • Run structured maturity assessments
  • Visualize gaps & progress via dashboards
  • Encourage teams through gamified progress indicators (badges, levels, seasonality)
  • Used in real-world consulting projects already (global deployment underway)

Your scope:

  • Full-stack web development
  • Back-end on Firebase (Firestore, Auth, Functions)
  • Front-end in React
  • Multi-user logic, multi-country scaling, admin panels

Your Responsibilities

  • Lead full-stack development for both products
  • Build & scale a React Native mobile app
  • Build & scale a React web app (Firebase stack)
  • Collaborate on architecture & product logic
  • Ensure security, performance & code quality
  • Connect to APIs (including BLE / fitness device data)
  • Contribute to roadmap decisions with the founder
  • Optionally: grow into a CTO-like role and lead a future tech team

Required Skills

  • 5+ years experience in full-stack dev
  • Strong in React & React Native
  • Strong in Firebase (Firestore, Authentication, Cloud Functions)
  • Experience with REST APIs, Git, Node.js
  • Familiar with BLE integration, data handling from external devices
  • Good sense of UX/UI and clean code architecture
  • Bonus: experience in dashboarding, SaaS platforms, or fitness/gaming

What I Offer

  • Full-time engagement, freelance to start
  • Autonomy and freedom to explore solutions
  • Full remote accepted + Physical meetings at least twice a month in Chennai or Bengalore.
  • Possibility of equity and evolution to CTO/co-founder (formal or informal)
  • Direct access to the founder
  • Creative autonomy & ownership
  • Meaningful tech, clear vision, international deployment
  • Based in Chennai or Bangalore preferred – hybrid is fine, but we need proximity

Interested? Know someone who could fit?

DM me or email felix.quemard@kerac.fr

Let's build something powerful, purposeful, and scalable – together.

Monthly Budget : up to 1.5 lakhs INR
