About the Role:
We are building systems that operate at scale - high write volumes, real-time state sync, and burst traffic that doesn’t politely warn before it arrives. We are looking for engineers who love owning systems end-to-end, care deeply about performance and reliability, and want to build things that don’t just work - but last. This is not a ticket-execution role, its a system ownership role.
  • Backend System Ownership:
  • Design and evolve Node.js / NestJS services powering systems that operate at scale
  • Take architectural decisions that balance scale, cost, and long-term maintainability
  •  
  • API Craftsmanship:
  • Build well-typed, thoughtful REST contracts for high volume flows
  • Think in versioning, backward compatibility, and clean boundaries
  •  
  • Data at Scale:
  • Model and optimize MongoDB / Firestore schemas for high read/write workloads
  • Design atomic updates and consistency strategies for distributed systems
  •  
  • Scalability & Resilience:
  • Implement queues, caching layers, and rate limiting to handle burst traffic gracefully
  • Design for failure modes before they happen
  •  
  • Frontend Integration:
  • Ship modular Vue 3 UIs that efficiently consume APIs
  • Optimize realtime updates and state management (Pinia)
  • Improve Core Web Vitals and perceived performance
  •  
  • Observability & Production Ownership:
  • Instrument logs, metrics, traces, and alerts
  • Participate in on-call
  • Debug real production issues
  • Drive post-mortems to meaningful closure (not just documents)
  •  
  • Mentorship & Leverage:
  • Review code thoughtfully
  • Support junior engineers
  • Raise engineering standards across the team
  • 4+ years of professional engineering experience
  • Strong backend-heavy fullstack background
  • Deep comfort with Node.js + TypeScript
  • Experience building and scaling microservices (NestJS / Express)
  • Modern frontend experience (Vue 3 or similar)
  • Strong understanding of: API design, Data modeling, Distributed systems tradeoffs, Concurrency & rate limiting
  • Real production debugging experience
  • Comfortable in cloud-native environments (GCP / AWS)
  • CI/CD and containerization familiarity
  • Pub/Sub or message queue experience
  • Event-driven systems exposure
  • Domain-driven design familiarity
  • Performance optimization work
  • Experience reducing infra costs
  • Location & Eligibility
