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
