• Deliver cross-cutting engineering work — platform components, refactors, integrations, and high-leverage features — at a pace achievable only through disciplined use of coding agents (Claude Code, Codex, or comparable) and modern agentic engineering practices. • Set the technical standard for the engineering organization. • Define and codify what good agentic engineering looks like at Marathon, including spec-driven development workflows, agent steering documents, custom Skills, MCP server patterns, subagent orchestration, and disciplined context engineering. • Package these as reusable skills, plugins, templates, and internal documentation that other engineers can adopt without reinventing them. • Drive architectural decisions that span Engineering, Data, and Infrastructure. • Partner with the Principal Architect and engineering leadership on systems design problems that cross team boundaries, lead ARB-level reviews, and bring strong fundamentals to API design, distributed systems, event-driven patterns, observability, and security within a HIPAA-regulated environment. • Build internal agents, MCP integrations, and RAG-backed applications where the return on investment is clear. • Apply agent development frameworks pragmatically, with appropriate evaluation, guardrails, and cost discipline. • Influence both what gets built and how it gets built. • Partner directly with engineering leaders, product partners, and internal stakeholders to shape initiative scoping, sequencing, and tradeoff decisions. • Bring product judgment and technical discernment upstream into the question of whether a problem warrants engineering investment — not just downstream into how the work is delivered. • Mentor senior and staff-level engineers across the organization. • Lead pairing sessions, design reviews, and brown-bags. • Grow agentic and AI-native engineering fluency across Engineering, Data, and Infrastructure through hands-on collaboration and visible example. • Operate as a healthcare-aware engineer. Respect PHI handling, BAA requirements, audit trails, clinical safety considerations, and regulated change management, and help teams move efficiently within these requirements.
