What you'll do

• Lead the design and implementation of complex backend features, distributed microservices, and asynchronous REST APIs optimized for high throughput, low latency, and fault tolerance.
• Design event-driven data pipelines, real-time message integrations, serverless functions, and distributed caching strategies to ensure data consistency and synchronization between modern and legacy data stores.
• Implement advanced error handling (retry patterns, circuit breakers), automated database migrations, and secure authentication/authorization flows (OAuth 2.0, JWT, RBAC).
• Implement micro frontend (MFE) architecture and low latency user interface systems.
• Manage cloud infrastructure via Infrastructure as Code (IaC), optimize containerized environments, and establish robust observability stacks (distributed tracing, metrics, logging).
• Maintain excellent automated test coverage (unit, integration, load testing), drive performance profiling, and foster team growth through code reviews, pair programming, and technical guidance.

What you'll need

• 5+ years of professional software development experience.
• 3+ years with high-level backend languages (e.g., Python, Go, Java) and frontend development (Angular).
• 2+ years scaling production distributed systems.
• Strong command of microservices communication, event streaming/message brokers, containerization, and event-sourcing concepts.
• Hands-on experience with major cloud ecosystems (serverless compute, managed storage, IAM), IaC tools, and secure API design principles.
• Exceptional analytical and communication skills, with a demonstrated ability to take absolute ownership of technical initiatives and lead alignment discussions in agile environments.

Nice to have

• Experience bridging modern cloud architectures with legacy database infrastructure.
• Experience optimizing automated CI/CD pipelines, high-availability setups, and disaster recovery planning.
• Familiarity with advanced telemetry dashboards (Prometheus/Grafana) and performance profiling tools.
