Lead Agent Engineer at LTS. . Location: United States - Remote. LTS. is seeking a . Lead Agent Engineer. to join a small, senior engineering team applying frontier AI to one of the most consequential legacy systems still running in production today.. . The mission: build agents that read, translate, and modernize a decades-old codebase that millions of people quietly depend on. The work has executive backing, real users, and a customer who knows exactly what they’re buying. Specifics shared once we’re talking.. . The team is small by design. Every seat carries unusual leverage, and we hire people who are already deep in this work. We use AI tooling natively — agents in parallel, model as collaborator, no exceptions.. . What You'll Do:. . The Lead Agent Engineer sets the technical ceiling on what the platform can do: translation accuracy, dependency-map correctness, hallucination control, multi-agent orchestration. Capability bets at the frontier of code understanding live here. So does the prompt-and-eval iteration cycle, in partnership with the RAG & Eval Engineer.. . . Own the agent layer of the platform — architecture, prompts, tool surfaces, multi-agent orchestration, and the eval loop.. . Set the technical ceiling for the platform’s core capabilities: translation accuracy, dependency-map correctness, hallucination control.. . Drive translation and dependency-mapping accuracy across an unfamiliar legacy paradigm — call graphs, data references, semantic equivalence checks.. . Take on capability bets that don’t show up on most roadmaps yet — agent work at the frontier of code understanding.. . Drive the prompt-and-eval iteration cycle in partnership with the RAG & Eval Engineer.. . Write production agent code daily; subagents and multi-agent workflows are your normal way of working.. . Establish foundations the rest of the team builds against — agent architecture, eval loop, prompt-and-tool patterns, multi-agent topology.. . . What We’re Looking For:. . . Bachelor’s degree in Computer Science, Engineering, or a related field, plus 5 years of professional software engineering experience; equivalent experience may substitute for the degree requirement.. . Has shipped at least one production agent (real users, real failure modes) and can describe in detail what broke and how it was fixed.. . Ability to work in a fast-paced, collaborative environment.. . Working fluency across the modern agent stack: tool use, MCP, evals, RAG, streaming, multi-agent coordination.. . Strong TypeScript or Python.. . Subagents and multi-agent workflows are a normal way of working.. . Comfort with measurement, regression detection, and prompt-and-eval iteration.. . Ability to operate without a roadmap — defines the next problem worth solving and goes.. . Heavy native use of AI tooling: agents in parallel, model as collaborator.. . Demonstrated experience in a remote work environment.. . Prior architectural ownership of an agent platform; track record of establishing eval and prompt patterns for a team.. . . Nice to Have:. . . Tooling around Claude or comparable frontier models at scale.. . Code-understanding agent work — translation, refactoring, test generation, dependency analysis.. . Background in compilers, program analysis, or static/dynamic code understanding.. . Open-source contributions to agent frameworks, MCP servers, or eval harnesses.. . Legacy-language or legacy-system exposure (rare, and a plus rather than a requirement).. . Public technical writing or conference talks on production agent work.. . Healthcare IT or legacy modernization domain experience.. . .  . . What’s in it for you? . . . The opportunity to support high visibility federal missions in IT and healthcare. . A culture that values innovation, growth, collaboration, and quality. . Access to cutting-edge tools and technologies. . Comprehensive benefits for you and your family. . A career path that rewards ambition and performance. . .  . .
