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.

LAB49 consultants are experts in strategy, user experience, architecture, engineering, and delivery management. We combine knowledge of the latest trends in technology with deep domain expertise to deliver innovative solutions with accelerated time-to-market.

We have office hubs in Midtown Manhattan, Washington DC, London, Budapest, New Delhi and Sydney.

Lab49/ION is committed to maintaining a supportive and inclusive environment for people with diverse backgrounds and experiences. We respect the varied identities, abilities, cultures, and traditions of the individuals who comprise our organization and recognize the value that different backgrounds and points of view bring to our business.
