About the Role

Lab49 is seeking a Senior Agentic Developer to engineer software using AI tools as a primary interface, focusing on modernizing legacy systems in regulated environments. This role is for curious engineers interested in an FDE-style mindset, combining technical expertise, customer impact, and AI-native workflows.

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.
  • Modernize and evolve legacy systems using AI-driven development workflows.
  • Apply “vibe coding” practices responsibly within highly regulated domains.
  • 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.
  • Influence how Lab49 and its clients adopt LLM-native software engineering practices at scale.

Requirements

  • Strong engineering fundamentals coupled with real-world experience solving difficult production problems in enterprise systems.
  • Hands-on experience manufacturing production-grade software in an AI-assisted way at scale.
  • Experience working within mature CI/CD environments, with automated testing fully integrated into the delivery pipeline.
  • Comfort working in regulated, risk-aware environments, where correctness, explainability, and traceability matter.
  • Ability to reason about system behavior, edge cases, and failure modes, even when the code is AI-generated.
  • Fluency in at least one major enterprise language or ecosystem (e.g., Java, C#, Python, JVM-based stacks, etc.).
  • Strong intuition for when to trust the model, and when not to.
  • Leading teams through the AI adoption journey and helping enterprises build scalable, robust AI software factory frameworks.
  • Interest in growing toward a Forward Deployed Engineering (FDE) style profile, combining technical excellence, customer engagement, and outcome-driven delivery.
  • Experience designing or using agentic development workflows (multi‑step prompting, tool‑using agents, code‑generation loops).
  • Exposure to modernization programs (monolith → services, legacy refactors, platform rewrites).
  • Opinions about how software engineering should evolve in an LLM‑first world - and the ability to defend them.
