Full Stack Engineer (Backend-Focused) - Onsite at mandin studios
Role Overview
This role is for someone who can take ownership of backend systems end-to-end, move fast, and ship production-grade features without constant supervision.
You’ll work directly on core systems: payments, integrations, data pipelines, and AI-driven features.
If you need hand-holding or clear step-by-step tickets for everything, this is not the role.
What You’ll Do
Own backend development from design to production
Build and maintain APIs using Node.js
Design scalable systems using MySQL / PostgreSQL
Integrate third-party services (BBPS, payment gateways, KYC, etc.)
Work on AI-powered features (spend analysis, recommendations, assistants)
Deploy, monitor, and maintain services (basic DevOps ownership expected)
Handle production issues, debugging, and performance optimization
Collaborate with frontend (Flutter) and product teams
Ship fast, iterate faster, and improve continuously
What We Expect (Core Skills)
Strong hands-on experience in Node.js backend development
Deep understanding of databases (PostgreSQL or MySQL)
Not just queries - indexing, performance, scaling
Experience integrating third-party APIs reliably
Solid understanding of system design and architecture
Working knowledge of DevOps (AWS, Docker, CI/CD, monitoring)
Experience building production-grade systems, not just side projects
Ability to debug real-world issues under pressure
AI & LLM Expectations (Non-Negotiable)
Practical experience with LLMs / AI integrations
Ability to build or integrate: a . AI assistants b. Data-driven insights systems c. Prompt workflows / pipelines
Understanding of where AI works and where it doesn’t (we don’t want blind API callers)
Good to Have (But Valuable)
Experience with Flutter (to coordinate better with mobile team)
Exposure to fintech systems or payments
Experience with real-time systems / event-driven architecture
Who You Are
You take ownership - you don’t wait to be told what to do
You learn fast and adapt faster
You care about shipping, not just writing code
You can balance speed and stability
You communicate clearly with both tech and non-tech teams
You don’t panic in production issues
Work Setup
Onsite role
Fast-paced environment - expect rapid iteration cycles
Direct impact on product decisions and architecture
What This Role Is Not
Not a “9–5 ticket executor” job
Not for someone who only knows frontend or only writes APIs without understanding systems
Not for someone new to real-world production environments
