Backend Engineer

Why This Role Matters
We’re building EASE, a next-gen healthcare platform powering clinical mental health and neurofeedback therapies. Our systems process real patient data, EEG signals, and therapy protocols used by clinicians every day.

What You’ll Build
● Scalable backend systems for patients, doctors, therapy sessions, and clinical protocols
● REST APIs using NestJS (TypeScript) powering web and device integrations
● Real-time EEG data pipelines from medical devices (MQTT + background jobs)
● Secure multi-role authentication systems (patients, doctors, admins, finance)
● High-performance databases and analytics layers for time-series medical data
● Fault-tolerant background jobs for EEG processing, reports, and automation

Your Day-to-Day
● Design and ship backend features end-to-end
● Own APIs, database schemas, and core business logic
● Work closely with frontend, product, and clinical teams
● Review code, mentor teammates, and raise the engineering bar
● Debug production issues and improve system reliability

Our Tech Stack
● Backend: NestJS (Node.js, TypeScript)
● Databases: MongoDB (core data), PostgreSQL (time-series EEG data)
● Real-time: MQTT (medical devices)
● Cloud: AWS (S3, SES)
● Testing: Jest
● Infra: Docker, PM2

What We’re Looking For
Must-Have
● 3–4 years of backend engineering experience
● Strong TypeScript + Node.js fundamentals
● Experience with NestJS or Express.js
● Solid understanding of MongoDB and SQL databases
● Hands-on experience building production APIs
● Comfortable with async systems and background jobs
 

Nice-to-Have (Not Required)
● Experience in healthcare, medtech, or regulated systems
● Real-time systems (MQTT, WebSockets)
● Redis, queues, caching strategies
● AWS or cloud infrastructure experience
● Event-driven or microservice architecture
