Provide technical leadership and mentorship to intermediate and junior developers. Participate in code and design reviews to maintain high-quality standards. Ensure high availability and reliability of the systems. Write clean, maintainable, and efficient code using industry best practices. Evaluate and adopt new technologies and practices relevant to the team's stack. Diagnose and resolve production issues across the stack using alerts, dashboards, and log analysis. Write and maintain automated tests to ensure system reliability. Use AI-assisted development tools while remaining accountable for the code they produce. Skills & Qualifications Degree or Diploma in Computer Science or related field. 5+ years of professional software development experience in Microsoft .NET. 2+ years of professional front-end experience with a modern framework: React preferred, Angular or Vue also valued.

Flexibility and adaptability to business requirements and priority changes. Self-motivated, team player, action and results oriented. Well-organized, good communication and reporting skills. Capacity to prioritize and effectively handle numerous tasks in a fast-paced, results-oriented environment. Ability to adapt to a diverse and reactive working environment. Initiative to work independently, but also able to work effectively with team members. Preferred Knowledge & Experience Extensive experience in design/development of highly scalable and high-performance distributed systems. Proven experience with message-oriented middleware systems such as RabbitMQ and Kafka. Experience with Redis. Experience with Kubernetes. Experience with cloud platforms (Azure preferred, AWS also valued). Experience with test automation. Experience with REST APIs, gRPC, WebSockets, or Server-Sent Events (SSE). Experience with observability tools (e.g., OpenTelemetry).
