Key responsibilities include providing technical authority to your team through hands-on leadership, owning the overall design, development, architecture, code quality, and production deployment for your team's work. You'll demonstrate a mentoring approach and be responsible for growing team members.
Required qualifications: BSc in Computer Science or equivalent; 5+ years backend development in .NET with practical React experience; 5+ years advanced SQL (MSSQL, Oracle, MySQL, PostgreSQL); SaaS platform experience on cloud (preferably AWS); containers and Kubernetes (K8s/EKS); message brokers (RabbitMQ, SQS, Kafka); microservices development; OOP and design patterns; engineering best practices (code reviews, testing, Agile); and a passion for managing and growing people.
