This position offers the chance to work on high-impact projects, including the migration of legacy systems to cutting-edge microservices architecture. Responsibilities: • Design and implement a robust, high-throughput request ingestion layer to handle tokenization and redirect services while ensuring low latency and reliability. • Migrate existing workloads into Docker containers and implement autoscaling capabilities using AWS services. • Develop and enforce multi-tenant isolation strategies, including per-client database configurations and rate-limiting mechanisms. • Replace cron-heavy workflows with event-driven or asynchronous processing solutions, such as queues and background workers. • Ensure system resilience to traffic spikes, high database write volumes, and millions of requests through advanced scalability techniques. • Establish operational safeguards, including logging, monitoring, kill switches, and cost controls to ensure system reliability and efficiency. • Modernize the current production stack by transitioning to stateless request handlers and horizontally scalable architectures. • Collaborate with senior developers to transform legacy systems into containerized, autoscaling microservices. • Optimize system performance while maintaining high security standards and protecting against abuse and misuse. • Implement client-isolated environments to support multi-tenant SaaS architecture.

• Proven expertise in designing scalable, high-performance production systems. • Strong hands-on experience with AWS technologies, including EC2, RDS, and networking configurations. • In-depth knowledge of autoscaling patterns, stateless service design, and high-throughput request handling. • Proficiency in Docker for containerization and experience migrating monolithic systems to microservices. • Practical understanding of database performance optimization and scaling strategies. • Ability to make confident, fast decisions under tight deadlines. • Familiarity with ASP.NET and .NET frameworks for application architecture and API development. • Pragmatic approach to system design prioritizing reliability and scalability over perfection.
