> Own end-to-end Sandboxes business at Blacksmith (product strategy, GTM, pricing, partnerships, revenue, team-building). Build the default execution platform for AI agents using existing compute fleet; requires technical credibility, product/GTM strength, and zero-to-one founder mentality.

## Job Description

## What you’ll do
- Develop a clear view of the sandbox market, customers, product, and how Blacksmith wins.
- Work directly with early customers building agents and other code-execution products, turning their needs into the roadmap.
- Make Blacksmith the default sandbox provider for AI startups, developer companies, and larger enterprises.
- Build repeatable acquisition, onboarding, retention, and expansion motions.
- Own pricing, packaging, partnerships, adoption, revenue, and unit economics.
- Establish Blacksmith as the technical and commercial leader in sandbox infrastructure.
- Recruit and lead a dedicated cross-functional team.

## Who you are
- Former founder, early leader at a developer-infrastructure company, or someone who has built a technical product from zero to meaningful adoption.
- Technically credible with engineers and technical founders.
- Strong across both product and go-to-market.
- Exceptionally ambitious and hungry to build something enormous.
- Comfortable personally selling, onboarding customers, and doing unscalable work before a mature motion exists.
- Highly urgent, hands-on, and effective in ambiguous environments.
- Able to move between strategy, customer conversations, product decisions, and execution.
- Excited to own an entire business rather than a single function.
- Fluent in developer platforms, distributed systems, workload isolation, infrastructure economics, APIs, reliability, and security.

## Compensation and benefits
- Medical, Vision, and Dental insurance.
- Competitive base + equity.
- Unlimited PTO.
- Annual offsite.
