Senior Agentic Developer - LLM‑Native / Enterprise

Salary Range: 220000 to 240000 (Currency: USD) (Pay period: per-year-salary)

What You’ll Do

• 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, not just assistants.
• Modernize and evolve legacy systems (often written in traditional enterprise stacks) using AI-driven development workflows.
• Apply “vibe coding” practices responsibly within highly regulated domains such as financial services, capital markets, or other compliance-heavy environments.
• 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, 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 results with clients.
• Hands-on experience manufacturing production-grade software in an AI-assisted way at scale (not just autocomplete or chat usage, but sustained code production through prompts, agents, or workflows).
• 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.

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
