About the role

<p></p> <p><strong>LTS</strong> is seeking a <strong>Senior Agent Engineer</strong> to join a small, senior engineering team applying frontier AI to one of the most consequential legacy systems still running in production today.</p> <p>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.</p> <p>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.</p> <p><strong>What You'll Do:</strong></p> <p>The Senior 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 &amp; Eval Engineer.</p> <ul> <li>Own the agent layer of the platform — architecture, prompts, tool surfaces, multi-agent orchestration, and the eval loop.</li> <li>Set the technical ceiling for the platform’s core capabilities: translation accuracy, dependency-map correctness, hallucination control.</li> <li>Drive translation and dependency-mapping accuracy across an unfamiliar legacy paradigm — call graphs, data references, semantic equivalence checks.</li> <li>Take on capability bets that don’t show up on most roadmaps yet — agent work at the frontier of code understanding.</li> <li>Drive the prompt-and-eval iteration cycle in partnership with the RAG &amp; Eval Engineer.</li> <li>Write production agent code daily; subagents and multi-agent workflows are your normal way of working.</li> </ul> <p><strong>What We’re Looking For:</strong></p> <ul> <li>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.</li> <li>Has shipped at least one production agent (real users, real failure modes) and can describe in detail what broke and how it was fixed.</li> <li>Ability to work in a fast-paced, collaborative environment.</li> <li>Working fluency across the modern agent stack: tool use, MCP, evals, RAG, streaming, multi-agent coordination.</li> <li>Strong TypeScript or Python.</li> <li>Subagents and multi-agent workflows are a normal way of working.</li> <li>Comfort with measurement, regression detection, and prompt-and-eval iteration.</li> <li>Ability to operate without a roadmap — defines the next problem worth solving and goes.</li> <li>Heavy native use of AI tooling: agents in parallel, model as collaborator.</li> <li>Demonstrated experience in a remote work environment.</li> </ul> <p><strong>Nice to Have:</strong></p> <ul> <li>Tooling around Claude or comparable frontier models at scale.</li> <li>Code-understanding agent work — translation, refactoring, test generation, dependency analysis.</li> <li>Background in compilers, program analysis, or static/dynamic code understanding.</li> <li>Open-source contributions to agent frameworks, MCP servers, or eval harnesses.</li> <li>Legacy-language or legacy-system exposure (rare, and a plus rather than a requirement).</li> <li>Public technical writing or conference talks on production agent work.</li> <li>Healthcare IT or legacy modernization domain experience.</li> </ul> <p>&nbsp;</p> <p><strong>What’s in it for you?&nbsp;</strong></p> <ul> <li>The opportunity to support high visibility federal missions in IT and healthcare</li> <li>A culture that values innovation, growth, collaboration, and quality</li> <li>Access to cutting-edge tools and technologies</li> <li>Comprehensive benefits for you and your family</li> <li>A career path that rewards ambition and performance</li> </ul> <p>&nbsp;</p> <p>If&nbsp;you’re&nbsp;ready to push boundaries, sharpen your skills, and join a team that is passionate about building&nbsp;what’s&nbsp;next,&nbsp;we’d&nbsp;love to meet you. Apply today and&nbsp;let’s&nbsp;build a future together!&nbsp;</p> <p></p><div class="content-conclusion"><p><strong>LTS </strong>shares salary ranges to promote transparency.
