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

What we're looking for

Minimum Requirement

Degree or equivalent and typically requires 7+ years of relevant experience.

Critical Skills

• 7+ years of professional software engineering experience.

• 5+ years building and shipping production software

• Strong system-design fundamentals and clean, testable, well-architected code

• Full-stack breadth: [TypeScript / Python / Go], modern frontend, APIs, and backend services

• 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 / DevSecOps or enterprise target="_blank">click here.
