What you will do

• Own and scale the Client Portal Notifications System for reliable, real-time delivery across in-app, push, and email channels.
• Design and optimize high-throughput, event-driven backend services that process over 10M notifications daily, ensuring high availability and minimal latency.
• Implement features such as multi-channel routing, message deduplication, rate limiting, and personalization.
• Build robust observability into the notification pipeline, covering monitoring, logging, and distributed tracing.
• Ensure data security, privacy compliance (CAN-SPAM, GDPR), and safe storage of user communication preferences.
• Collaborate with product, infrastructure, and frontend teams to design APIs, event schemas, and SDKs.

Requirements

• 4+ years of hands-on software engineering experience building and scaling high-volume distributed systems or event-driven architectures.
• Strong backend engineering and distributed system design skills, with hands-on experience in API development, data modeling, and systems architecture using Node.js (NestJS preferred), TypeScript, PostgreSQL, MongoDB, and Redis.
• Expertise in backend performance optimization, caching strategies, and event-driven architectures (e.g., Redis, Kafka, Pub/Sub).
• Familiarity with notification protocols and integrations (SMTP, FCM, APNs, in-app SDKs) and email templating systems.
• Strong understanding of security best practices across the full stack—including authentication, authorization, access control, secure data flow, and privacy compliance.
• Excellent communication and cross-functional collaboration skills, able to drive complex initiatives and lead technical discussions.

Nice to have

• Familiarity with modern frontend frameworks (React, Vue, Angular), advanced UI engineering patterns, and CSS libraries like Bootstrap or Tailwind CSS.
• Advanced experience with complex state management libraries (e.g., Redux, Vuex, MobX) and architectural design of large-scale application state.
• Proven track record of optimizing frontend performance and web vitals at scale, including experience with server-side rendering (SSR), edge, or hybrid rendering architectures.
• Familiarity with frontend and backend observability—including monitoring, tracing, error tracking, and performance profiling in production (e.g., Grafana, Prometheus, Sentry, PostHog).
