Position Summary

Turn intent into production software - and build the platform that does it.

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.

What you'll do

• Design and build core components of the Bolt harness - skills, commands, platform tools, and the guardrails that keep AI-generated code safe and standards-compliant

• Develop tooling that makes agentic development reliable and efficient - orchestration, context/token optimization, and reusable templates

• Strengthen the enterprise guarantee layers: design systems, shift-left security, data integration, and automated verification & validation

• Own the path from spec to shipped software across multiple environments, including CI/CD and secrets management

• Set the technical bar through architecture, code review, and mentorship

• Strong with cloud infrastructure and IaaS ( AWS / Azure / GCP ), containers, and CI/CD in an enterprise setting

• A proven automation mindset - a track record of eliminating toil and building things that scale without manual effort

• A customer-first mindset
  , with a habit of grounding technical decisions in real user needs

• Genuinely passionate about the fast-changing AI landscape and eager to build on the frontier of agentic development

• A track record of owning projects from ambiguity to launch

• Clear communication and a strong bias toward action

Nice to have

• Hands-on experience with LLMs or agentic AI systems - prompt/context engineering, tool use, agent orchestration

• Background in developer platforms, internal tooling, or SDKs

• Application security / Dev Sec Ops  or enterprise data-platform experience

• Healthcare or other regulated, large-scale enterprise environments

Why join us

• Shape a platform that's redefining how enterprise software gets built in Health Tech

• Real ownership and the autonomy to make it count
