Responsibilities
Own feature delivery from concept to production for the Sub-Accounts platform — design APIs, implement backend logic, and build clean, responsive frontend experiences (any modern UI framework; Vue.js experience is a big plus)
Build and evolve highly scalable, performant microservices using Node.js, MongoDB, Redis, and event-driven patterns running on Kubernetes and GCP
Proactively hunt down and fix systemic issues (race conditions, deadlocks, memory leaks, timeouts, data inconsistencies) across the sub-accounts hierarchy and permissions system
Drive performance and cost optimizations — query tuning, intelligent caching, indexing strategies, and GCP cost reduction without sacrificing speed or reliability
Ruthlessly reduce technical debt through refactoring, improving test coverage, and eliminating anti-patterns in both backend and frontend code
Strengthen security at every layer — RBAC/ABAC enforcement, tenant isolation, audit trails, rate limiting, secrets management, and input validation
Improve observability across the stack — meaningful logs, metrics, distributed tracing, and alerts that make incidents easy to debug in real time
Work hand-in-hand with QA from day one: review test cases, give live demos during QA handover, and resolve feedback quickly
Build internal tools, scripts, and automation that accelerate development, testing, and deployment cycles for the entire team
Actively pair with teammates, share knowledge, conduct code reviews, and help unblock others
Participate in on-call rotation and own incident resolution for the sub-accounts services you build
Qualification
Required
4–7 years of hands-on engineering experience with proven exposure to scale (high TPS, large datasets, or complex multi-tenant/multi-account systems)
Expert-level Node.js and a strong habit of writing clean, modular, reusable code
Deep expertise with MongoDB (complex schemas, aggregation framework, indexing, sharding, change streams)
Solid production experience with Redis (caching, rate-limiting, pub/sub, distributed locks, session management)
Real-world experience building and operating microservices on Kubernetes (deployments, services, configmaps, helm, basic troubleshooting)
Strong hands-on experience with any major cloud provider (GCP, AWS, or Azure) – you know how to use managed services for containers, queues, caches, serverless, and databases effectively
Comfortable building responsive, high-quality UIs with any modern frontend framework (Vue.js is a big plus; React or Angular experience works perfectly too)
You've shipped and supported large-scale, mission-critical systems that stayed stable under heavy load
You're passionate about modular architecture, obsess over performance and GCP cost optimization, and can seamlessly jump into the frontend to deliver complete, polished features
Preferred
Experience with AI Tools and contributions to open-source tools, internal platforms or engineering blogs
NestJS or Express.js experience
Elasticsearch for advanced search/filtering use cases
