Posted Apr 28AI Agent Infrastructure Lead
at Sphere
On-site
Responsibilities
- - Own the infrastructure, tooling, and workflows that let agents safely take on more complex internal work over time.
Requirements
- Our AI (TRAM) ingests global trade law, interprets it, resolves conflicts across jurisdictions, and produces compliance determinations more reliable than human experts.
- THE ROLE Sphere is looking for an engineer to lead our internal AI agent enablement efforts.
- You’ll build the systems that let AI agents safely and effectively increase velocity across.
- WHAT YOU'LL DO Within days - Ship AI agent features that help Sphere’s engineering team use agents more effectively and responsibly. - Iterate on versions of Sphere’s agent sandbox environments. - Create workflows where agents can inspect the codebase, run local infrastructure, make changes, run tests, and prepare work for human review. - Work directly with engineers to identify high-leverage internal workflows where agents can create immediate velocity.
- Within months - Lead Sphere’s internal efforts to enable AI agents to act more autonomously across engineering, ops, customer success, tax research, and implementation.
- - Build “Goose” for Sphere: the internal AI agent layer that helps agents understand and operate across Sphere’s systems.
- Experience in AI agents, coding agents, internal developer tooling, or AI agent enablement. - Comfort working across backend systems, infrastructure, local development environments, CI, and internal tools. - Strong judgment around autonomy, safety, permissions, and human review. - High agency.
Benefits
- We handle the entire lifecycle — calculation, registration, filing, remittance — at millisecond latency with zero downtime. - Backed by a16z and YC. $21M Series A, 30%+ month-over-month growth, customers include ElevenLabs, Replit, Deel, Runway, and Lovable. - Small team, global surface area.
- Expanding into input tax, withholding, e-invoicing, tariffs — each multiplies the complexity.
Additional details
- ABOUT SPHERE Every breakthrough in trade infrastructure has followed the same pattern: reduce a transaction cost, expand the market.
- Compliance is one of the last and largest — and the hardest, because trade rules aren't data to be looked up.
- They're a complex adaptive system with 190+ sovereign jurisdictions, in different languages, changing constantly, reacting to each other.
- Everyone owns a domain that would be a full team at a larger company.
- San Francisco, five days in office. - The problem keeps compounding.
- Tens of millions of transactions today, billions ahead.
- Sphere, starting with engineering and expanding into ops, customer success, tax research, and implementation workflows.
- - Establish the patterns for how Sphere uses agents internally, including context, permissions, review, observability, and escalation. REQUIREMENTS -
- Experience building production-quality software. -
- You can take a vague internal problem and turn it into a working system people actually use. - Strong attention to detail.
