Sphere AI is building Abe — an AI Business Engineer that deploys into operations teams, connects to their systems, speaks their language, and does the work. Production solutions built on their systems of record — RBAC, audit trails, and zero data leakage into foundation models. No migrations. No rip-and-replace. Ship real enterprise AI from week one.

Sphere's AI orchestration expert. You'll experiment deeply with Claude Code, build reusable AI patterns, and shape our core orchestration architecture. Rapid learning, competitive compensation, meaningful equity, and fully covered healthcare.

Claude Code Mastery Become the team's Claude Code expert through extensive experimentation. Master skills, subagents, tools, and hooks—understand deeply when to apply each pattern and why. Document learnings and share with team and Anthropic.

Orchestrator Architecture Build and refine AI orchestrators as RPC for realtime decisioning. Establish patterns the entire platform uses. Design for latency, error handling, observability, and testing in AI systems.

Experimentation Culture Constantly test Claude Code boundaries, push capabilities, discover what's possible. Create reusable orchestration patterns and templates that accelerate platform development. Be at the frontier.

• Become the team's Claude Code expert through extensive hands‑on experimentation
• Build 3-5 production orchestrators demonstrating different patterns (skills vs. subagents vs. tools vs. hooks)
• Create orchestration playbook: when to use which pattern, with working examples and decision trees
• Present weekly learnings to team showing what you discovered about AI orchestration

Must Have:

• Hands‑on Claude Code experience (actively experimented, not just used Claude chat; can show skills/subagents/tools you've built and articulate trade‑offs)
• Systems thinking for AI (understands orchestrators as RPC for realtime decisioning; thinks about latency, error handling, observability, testing)
• Tinkerer mentality (constantly experimenting, pushing boundaries, documenting what works/doesn't; excited to be at frontier of AI orchestration)

Nice to Have:

• Contributed to Claude Code skills or shared orchestration patterns publicly
• Backend engineering experience (understands APIs, async patterns, error handling)
• Experience with other AI orchestration frameworks (Lang Chain, AutoGPT, CrewAI) for comparison

Shape the Future of AI Development AI orchestration is the new infrastructure layer. You'll define patterns that become industry standards. This expertise doesn't exist yet—you'll help create it.

Direct Access to Frontier Work with Anthropic's latest capabilities before most engineers know they exist. Your experiments inform both our product and Anthropic's roadmap.

Become Irreplaceable In 18 months, you'll be one of ~100 people globally with deep AI orchestration expertise. This knowledge compounds—every company building with AI will need what you know.

Most AI transformations stall in slide decks and endless migrations. At 1
