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.
Responsibilities:
- 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
Requirements:
- 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
Nice to Have:
- Pub/Sub or message queue experience
- Event-driven systems exposure
- Domain-driven design familiarity
- Performance optimization work
- Experience reducing infra costs
