Job Description
"Unlock the secrets of building scalable, high-performance backend systems with NestJS, Redis, and PostgreSQL as a Senior Backend Engineer at GoodSpace AI."
As a Senior Backend Engineer at GoodSpace AI, you will be responsible for designing and building the backend infrastructure that powers our mobile app's UI, driving a dynamic and engaging user experience.
In this role, you will lead a small team, make high-level architectural decisions, and build scalable systems that can handle high-traffic events, ensuring our app remains fast, reliable, and secure.
Why you should learn this:
The demand for skilled backend developers is on the rise, with the global market expected to reach $2.4 billion by 2025.
Expected Salary: $120,000 - $200,000 per year, depending on experience and location.
How it works:
- Step 1: Design and build the Backend-for-Frontend (BFF) layer using NestJS, which serves dynamic UI layouts to the mobile app.
- Step 2: Architect scalable database schemas, caching strategies (Redis), and background workers (BullMQ) for high-traffic events, ensuring efficient data retrieval and processing.
