Agentic Developer, LLM‑Native / Enterprise (Contractor)
Explicitly requires vibe coding: using LLMs and agentic workflows as primary development tools to rapidly generate and iterate production code.
About the Role
Lab49 is hiring an Agentic Developer to generate and maintain production-grade enterprise code using large language models as primary development interfaces. The role focuses on modernizing and extending complex legacy systems in regulated environments while ensuring rigor, compliance, and reliability.
Job Description
Role
Agentic Developer (LLM‑Native / Enterprise, Contractor, Hybrid) responsible for producing, refactoring, and extending enterprise-grade code by orchestrating large language models as first-class development tools. The role emphasizes modernization of legacy systems in regulated, compliance-heavy domains and driving adoption of LLM-native engineering practices.
Key Responsibilities
- Generate, refactor, and extend production enterprise code using LLMs and agentic development workflows.
- Modernize and evolve legacy systems (traditional enterprise stacks) with AI-driven development processes.
- 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.
- Operate within mature CI/CD environments with automated testing integrated into delivery pipelines.
- Collaborate with product managers, architects, and clients to translate ambiguous requirements into working systems quickly.
- Influence how the firm and clients adopt LLM-native software engineering practices at scale.
Requirements
- Strong software engineering background with experience in enterprise or legacy systems.
- Hands-on experience producing production-grade software via AI-assisted workflows (beyond simple autocomplete/chat use).
- Experience working within mature CI/CD environments and automated testing practices.
- Comfort in regulated, risk-aware environments where correctness, explainability, and traceability are required.
- 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 given: Java, C#, Python, JVM-based stacks).
- Strong judgment about when to trust model outputs and when not to.
- Experience leading teams through AI adoption and building scalable AI software factory frameworks.
Nice to Have
- Experience designing or using agentic development workflows (multi-step prompting, tool-using agents, code-generation loops).
- Exposure to modernization programs (monolith refactors, platform rewrites).
- Well-formed opinions about the evolution of software engineering in an LLM-first world and ability to defend them.
