Description :

- Own and contribute to architecture and development across Agency Module, Billing, and Affiliate systems, driving technical excellence across frontend and backend services.

- Design and implement robust backend APIs for subscription management, payments, invoicing, and affiliate tracking, using test-driven development and scalable distributed patterns (caching, messaging, queuing).

- Deliver performant frontend experiences for agency onboarding, billing dashboards, and affiliate management using modern frameworks and component-driven architecture with strong state management principles.

- Architect secure integrations with third-party payment gateways (e. g., Stripe) and internal microservices, ensuring accuracy, reliability, and compliance in all financial transactions.

- Implement and maintain observability, logging, and monitoring to ensure high availability and rapid incident resolution across critical billing and agency workflows.

- Champion platform security and compliance by enforcing best practices across authentication, authorization, data protection, and rate-limiting, ensuring the integrity of sensitive financial and user data.

- Leverage LLMs and AI-assisted tools to accelerate development, automate testing, refactoring, and documentation, while maintaining strong reliability guardrails.

- Collaborate cross-functionally with product managers, designers, and other engineering teams to ensure alignment between business goals and technical architecture.

- Participate in technical reviews, deep dives, and on-call rotations, fostering a culture of accountability, operational excellence, and continuous improvement.

Requirements :

- 4+ years of hands-on software engineering experience building and scaling robust backend systems and high-performance frontend applications.

- 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, and Pub/Sub).

- Familiar 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).

- 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, lead technical discussions, and mentor junior engineers.
