Explicitly requires vibe coding skills — using LLMs as first-class development tools and designing agentic workflows to produce enterprise code rapidly while maintaining compliance.

About the Role

Contractor role for an Agentic Developer who uses large language models as a primary development interface to generate, refactor, and modernize production-grade enterprise code. The role focuses on designing agentic workflows, validating AI-generated code for security, auditability, and compliance, and guiding enterprises through LLM-native engineering practices in regulated environments.

Job Description

Role

Agentic Developer (LLM-Native / Enterprise) — contractor role focused on using large language models as first-class development tools to generate, refactor, and modernize production-grade enterprise code, especially within regulated or compliance-heavy domains.

Key Responsibilities

  • Generate, refactor, and extend enterprise-grade codebases by orchestrating LLMs as primary development tools.
  • Modernize and evolve legacy systems (often in traditional enterprise stacks) using AI-driven development workflows.
  • 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 with product managers, architects, and clients to translate ambiguous requirements into working systems quickly.
  • Influence adoption of LLM-native software engineering practices at scale within client organizations.

Requirements

  • Strong software engineering background with experience in enterprise or legacy systems.
  • Hands-on experience producing production-grade software via sustained AI-assisted development (beyond simple autocomplete or chat usage).
  • Experience working within mature CI/CD environments with automated testing integrated into delivery pipelines.
  • Comfort operating in regulated, risk-aware environments where correctness, explainability, and traceability matter.
  • Ability to reason about system behavior, edge cases, and failure modes, including for AI-generated code.
  • Fluency in at least one major enterprise language/ecosystem (examples cited: Java, C#, Python, JVM-based stacks).
  • Strong judgment about when to trust model outputs and when not to, and ability to lead teams through AI adoption.

Nice to Have

  • 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).
  • Well-formed opinions about how software engineering should evolve in an LLM-first world and ability to defend them.

Location & Employment

  • Contractor role with office hubs in Midtown Manhattan, Washington DC, London, Budapest, New Delhi, and Sydney.
