  • Working knowledge of agentic workflows, spec-driven development (translating low-level design artifacts such as class structures, API contracts, and data models into structured specs that guide AI-assisted implementation), and custom instructions and prompt engineering, with the ability to establish team-level practices for effective AI-assisted development.
• Education: Bachelor's degree in Computer Science, Software Engineering, or related technical field, or equivalent practical experience
• Experience:
  • 7+ years of professional software engineering experience in actively developing large-scale software using C#, .NET/.NET Core, ASP.NET, cloud-native development, and Web Services/APIs, supporting high-volume transactions in a highly available, mission-critical environment.
  • 2+ years of hands-on experience with AI/ML implementation and production deployment
  • 6+ years of experience working with containers and microservices in the cloud.
  • 6+ years of experience in cloud deployment in a continuous integration, and continuous delivery model (CI/CD).
  • 2+ years of experience with Pivotal Cloud Foundry (PCF), or AWS or GCP.
  • 2+ years' experience working with databases like MongoDB, Aerospike, and/or PostgreSQL.
  • 2+ years Prior experience in IT Transformations and system modernization initiatives from legacy to distributed platforms, i.e., Mainframe Cobol apps/DB2 to Java apps/SQL or MongoDB
  • Hands-on experience with Large Language Models (e.g., GPT-5, Claude, Gemini, PaLM)

• Domain Expertise: Understanding of broker-dealer capabilities and operations.
