• Work with SQL Server and T-SQL for querying, troubleshooting, and supporting application data
• Support MongoDB/DocumentDB document storage and reason about relational and document database usage across application services
• Design and support event-based, message-driven architecture using MassTransit over message brokers such as Amazon SQS, RabbitMQ, and Apache MQ across distributed application services
• Apply AI-assisted development tools (e.g., GitHub Copilot, Devin) to coding, debugging, documentation, and PR workflows to measurably improve team productivity
• Review, validate, and govern AI-generated code and infrastructure-as-code; evaluate emerging AI productivity tools and recommend adoption across engineering teams
• Adapt deployment processes and engineering practices as platform requirements and tooling evolve
• Mentor and guide engineers across the stack, raising the bar on code quality, architecture, and operational practices
• Lead technical decisions and provide hands-on guidance on complex, cross-cutting problems from development through production troubleshooting
• Partner with engineering leadership to set technical direction, plan coordinated releases, and onboard and grow team members

Requirements:

• 8+ years of experience in software, DevOps, or platform engineering, including time as a senior individual contributor or technical lead, with hands-on AWS infrastructure management (VPCs, EC2, Kubernetes, load balancers, and network security controls such as firewalls, WAF, and network ACLs)

• Experience with SQL Server, MongoDB/DocumentDB, and event-based, message-driven systems (MassTransit, Amazon SQS, RabbitMQ, or Apache MQ)
• Proficiency with Git-based source control workflows (GitHub or GitLab), including branching strategies, code reviews, and coordinated deployments
• Demonstrated ability to mentor engineers and lead technical decisions, balancing hands-on contribution with guidance and team development
• Demonstrated use of AI coding assistants (e.g., GitHub Copilot, Devin) to accelerate development and improve code quality in daily engineering workflows
• Familiarity with CMS and identity platforms such as Umbraco and Identity Server
• Experience supporting complex distributed applications from development through deployment and production troubleshooting
