About the role

Senior Agentic Developer leveraging AI-native workflows to generate production-grade enterprise code, modernize legacy systems, and apply agentic AI practices in highly regulated environments within Lab49/ION.

Responsibilities

  • Continuously experiment with emerging AI tools, development techniques, and agentic workflows to accelerate delivery and improve client outcomes.
  • Partner with clients to turn innovative AI capabilities into practical, production-ready solutions that create measurable business value.
  • Generate, refactor, and extend enterprise-grade codebases by orchestrating LLMs as first-class development tools, not just assistants.
  • Modernize and evolve legacy systems using AI-driven development workflows.
  • Apply “vibe coding” practices responsibly within highly regulated domains such as financial services, capital markets, or other compliance-heavy environments.
  • Design and guide agentic workflows where LLMs reason, iterate, and produce code aligned with business and architectural constraints.
  • Validate, test, and harden AI-generated code to meet production, security, and audit standards.
  • Collaborate closely with product managers, architects, and clients to translate ambiguous requirements into working systems, fast.
  • Influence how Lab49 and its clients adopt LLM-native software engineering practices at scale.

Qualifications

  • Strong engineering fundamentals with real-world enterprise problem-solving experience.
  • A passion for continuous learning, experimentation, and delivering results for clients.
  • Hands-on experience producing production-grade software in an AI-assisted way at scale (beyond basic autocomplete or chat usage).
  • Experience in mature CI/CD environments with automated testing integrated into the delivery pipeline.
  • Comfort in regulated, risk-aware contexts where correctness, explainability, and traceability matter.
  • Ability to reason about system behavior, edge cases, and failure modes in AI-generated code.
  • Fluency in at least one major enterprise language (e.g., Java, C#, Python, JVM stacks).
  • Strong judgment on when to trust AI models and when not to.
  • Experience leading teams through AI adoption and building scalable AI software factory frameworks.
  • Interest in growing toward Forward Deployed Engineering (FDE) style profile.
