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.

As a Platform Engineer at 1

Sphere, you'll ship essential platform components, support production systems, and integrate enterprise solutions for leading companies. Work with cutting-edge AI tools, enjoy a competitive package, equity, and fully covered benefits.

Service Delivery Build and ship platform components (auth, connectors, APIs) that product teams depend on. Write clean, tested code that becomes the foundation for customer workflows.

Production Support Own on-call for platform services, resolve incidents, maintain reliability. Debug production issues, write runbooks, establish operational excellence.

Customer Enablement Deploy platform services to customer environments (SAP, Salesforce, Workday, Service Now) and iterate based on real-world usage. Build data connectors that integrate seamlessly with enterprise systems.

• Ship platform services to staging with comprehensive tests and monitoring
• Build 3-5 data connectors to major enterprise systems (SAP, Salesforce, Workday, Service Now)
• Establish on-call rotation and incident response patterns
• Support first customer deployments and gather feedback for iteration

Must Have:

• 2+ years backend/platform experience (shipped production services; can show systems you built or describe architecture)
• Used AI coding tools recently (Cursor, Claude, or Copilot in last 3 months; can show what you built faster and how you directed the tools)
• Production debugging skills (debugged live incidents, written runbooks, owned on-call)

Nice to Have:

• Multi-tenant SaaS experience (tenant isolation, row-level security)
• Built integrations to enterprise systems (REST APIs, OAuth, rate limiting)
• Experience with Go (our primary backend language)

Ship Fast, Learn Faster Every 90 days, you'll see your work come alive. Real integrations, real customers, real outcomes—zero vaporware. While others debate in meetings, you'll be deploying.

AI-Native From Day One Use next-gen AI orchestrators (Claude Code, Cursor, Codex) daily, mastering the tools that ensure your career stays future-proofed. You're not just learning about AI—you're becoming fluent in it.

Ownership As a key team member, your impact is immediate and your growth exponential. Meaningful equity, visible responsibilities, and direct influence on our trajectory. This is the ground floor.

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

Sphere, we break the cycle—shipping real enterprise AI solutions in 90-day sprints, delivering tangible outcomes for Fortune 500 giants like SAP, Salesforce, Workday, and Service Now.

Founded by the former Co-Founder and CTO of Abnormal Security (trusted by 25%+ of Fortune 500), we're not just riding the AI wave—we're building the infrastructure that powers it.

• Competitive salary + meaningful equity
• Medical/dental/vision covered at 100% for employee and dependents
• SF Bay Area headquarters (in-person - building culture and velocity requires proximity)
