Senior Agentic Developer, LLM‑Native / Enterprise, NY

Lab49 is a specialist strategy, design, and technology consulting company dedicated to the financial services industry. We were founded in 2002 to fill a need in the Financial Technology marketplace for high-end execution and reliable delivery of technology projects. Lab49 is now looking for a Senior Agentic Developer, an engineer who doesn’t just use AI tools but writes software through them. We are looking for bright, curious engineers who thrive on continuous learning, experimentation, and delivering tangible results for clients. This role is ideal for developers interested in evolving toward an FDE-style mindset, combining deep technical expertise, customer impact, and AI-native ways of working. This is not a role focused on “adding AI features” or “building AI platforms.” Instead, we are seeking an experienced developer who generates production-grade enterprise code using large language models as a primary interface, particularly while modernizing or extending complex, legacy systems in highly regulated environments. You will operate as a vibe coder in the best sense of the term: combining deep engineering intuition, strong system design instincts, and fluent command of LLMs to move faster than traditional development workflows, without compromising rigor, compliance, or reliability. What You’ll Do Continuously experiment with emerging AI tools, development technique [... source excerpt omitted ...] 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. What We’re Looking For Strong engineering fundamentals coupled with real-world experience solving difficult production problems ("battle scars") in enterprise systems A passion for continuous learning, experimentation, and achieving resu [... source excerpt omitted ...] 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. 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) Opinions about how software engineering should evolve in an LLM‑first world - and the ability to defend them LAB49 consultants are experts in strategy, user experience, architecture, engineering, and delivery management.
