Bolt is McKesson's AI-first platform for rapid enterprise application development. Instead of hand-writing every line, or vibe coding fragile systems, teams describe their intent — and Bolt's agentic harness turns it into enterprise-grade, production-ready software, with design, security, and data standards baked in from the first commit. We're hiring a Senior Software Engineer to help build the platform itself: the harness, tooling, and guardrails that let AI agents (like Claude Code) ship real enterprise software — safely and fast. This is a build role at the frontier of AI-assisted software development.
