Senior Consultant / Architect - AI-Driven Modernization (North America) (Engineering / Architecture

CAST Software Inc.

Millerton, NY • On-site, Remote

$131K - $178K/yr

Full-time

Re-posted 12 days ago

Job description

CAST Software is the global leader in Software Intelligence. We help enterprises understand, improve, and transform complex software systems.
Our platform provides deterministic system-level insight into large codebases, which-combined with AI models and agents-enables enterprises to move from experimentation to production-grade AI outcomes in brownfield environments.
About the Role
We are hiring strong engineers and architects who want to move beyond pure development into end-to-end ownership of real-world outcomes in the AI era.
You will work directly with large enterprise codebases (often millions of lines of code), using CAST and AI tools to:
  • Understand system architecture and dependencies
  • Enable AI-assisted modernization and transformation
  • Ensure outputs are accurate, complete, and production-ready

This is a role for someone who wants to stay deeply technical while stepping into higher-impact, customer-facing ownership.
What You'll Do
Work on Real Enterprise Systems
  • Analyze large, complex codebases (.NET, Java, SQL, etc.)
  • Reconstruct architecture, dependencies, and data flows using CAST Imaging
  • Identify risks, hidden dependencies, and modernization blockers
Enable AI-Assisted Transformation
  • Use tools such as VS Code, GitHub Copilot, Claude, and CAST MCP to:
    • Support code transformation (.NET → Java, legacy → modern frameworks)
    • Validate structural and functional accuracy of AI-generated outputs
  • Ensure transformations preserve:
    • Dependencies and integrations
    • Architecture integrity
    • Security and operational requirements
Bridge Deterministic Insight and AI
  • Ground AI outputs in deterministic system context
  • Identify gaps where AI-only approaches fall short (e.g., missing layers, incorrect flows)
  • Iterate toward deployable, production-ready outcomes
Own Customer Outcomes
  • Work directly with engineering and architecture teams
  • Translate technical insights into clear action plans
  • Drive progress from:
    • Initial analysis → transformation → adoption
Expand into Customer Ownership
  • Lead technical discussions with:
    • Architects, engineering leads, and CTO organizations
  • Contribute to executive conversations with clear, structured insights
  • Gradually take on broader ownership of customer success and outcomes

Who You Are
  • 5-12+ years in:
    • Software engineering, architecture, or modernization
  • Strong experience with:
    • Java, .NET, SQL, distributed systems
    • Enterprise application architectures
  • Comfortable working with:
    • Large, complex, poorly documented systems
  • Exposure to or strong interest in:
    • AI/GenAI for software development
    • Code transformation and modernization
  • Strong problem-solving mindset - able to trace issues across systems
  • Good communication skills, with interest in becoming more customer-facing

What Makes This Role Different
  • You work on brownfield systems where correctness matters
  • You don't just generate code - you validate and make it real
  • You bridge AI capability with system reality
  • You evolve from architect → customer owner
  • You are positioning your career at the center of the AI shift - working on the exact problems that will define how AI is used in enterprise software, not just experimenting at the edges
