• Partner directly with business and technical stakeholders to communicate incident status, RCA findings, and improvement recommendations.
• Participate in on-call rotation and CAB (Change Advisory Board) processes as required.

• 8 years of hands-on experience in .NET application development and/or production support.
• Strong expertise in C#, ASP.NET Core, .NET Framework.
• Front-end experience with Angular and/or React.
• Solid understanding of microservices architecture and REST API design/support.
• Advanced SQL Server skills - performance tuning, execution plan analysis, query optimization.

• Experience supporting batch processes, scheduled jobs, and system integrations.
• Strong incident management and RCA discipline, ideally within an ITIL-aligned environment.
• Experience with tools such as ServiceNow, Jira, Splunk, or equivalent monitoring/ticketing platforms.

Good to Have

• Experience in Banking / Financial Services production support environments.
• Exposure to Appian or low-code platforms.
• Familiarity with DevOps automation, branching strategies (e.g., BODM/trunk-based models), and release engineering.
• Prior experience mentoring or leading L2/L3 support pods.

Soft Skills / Attributes

• Calm, methodical operator under production-incident pressure.
• Strong stakeholder communication - able to translate technical RCA into business-readable updates.
• Ownership mindset with a bias toward permanent fixes over temporary patches.
• Comfortable operating in a regulated, compliance-conscious banking environment.
