The ideal candidate is a hands-on engineering leader who enjoys solving complex platform problems, working across distributed teams, and building reliable systems that support critical financial operations. You should be comfortable moving between architecture discussions, coding, code reviews, production troubleshooting, and stakeholder conversations.

In this role, you’ll make an impact in the following ways:

• Modernize Eagle Accounting platform capabilities by building scalable services for high-volume accounting and data processing workflows.
• Build a multi-tenant, cloud-based accounting platform capable of ingesting data in both real-time and batch modes.
• Design, build, test, deploy, and operate highly scalable API-driven services, primarily using Java, with SQL and NoSQL databases, hosted in Microsoft Azure and on-prem platforms.
• Evolve legacy platform capabilities into modern cloud-ready and API-first services.
• Provide technical leadership across design, implementation, testing, deployment, and production support while mentoring engineers and helping the team maintain high standards for quality, resiliency, scalability, and maintainability.
• Build software with strong attention to reliability, observability, auditability, data quality, and operational controls in a highly regulated financial services environment.
