1Sphere is pioneering AI transformation for the Fortune 500.

Founded by Sanjay Jeyakumar (previously Co-founder/CTO at Abnormal Security—now valued at $5B+, securing 25%+ of the Fortune 500), we're assembling an elite founding-stage team in Oakland to repeat this success in enterprise AI. Ship real solutions in weeks, master AI-native tooling, and make real impact to our F500 customers.

Software Engineer – Full-Stack

Join 1Sphere as a Full-Stack Engineer to create polished, customer-facing features. You'll build intuitive UIs, robust APIs, and deliver complete solutions rapidly. Showcase your work weekly, benefit from competitive compensation, meaningful equity, and comprehensive health coverage.

What You'll Own

Feature Delivery Own Studio (code generation), Runtime (deployment dashboards), and Guardrails (monitoring UIs). Ship complete features from design to deployment that customers use daily.

End-to-End Ownership Design, implement, test, deploy, and iterate based on customer feedback. Own the full stack—no handoffs, no waiting. Your features, your responsibility, your impact.

Demo Culture Show weekly progress and shipped features to customers and team. Build in public, gather feedback, iterate fast. Make demos so compelling they become sales assets.

Your First 90 Days

Ship Studio UI features (workflow editor, preview, deployment controls)
Build Runtime dashboards showing workflow status, logs, and metrics for customers
Establish weekly demo cadence showcasing shipped features
Gather customer feedback and implement 2-3 major improvements based on usage

What We're Looking For

Must Have:

2+ years full-stack experience (shipped production web apps with modern frontend and backend APIs)
Used AI coding tools recently (built features with Cursor, Claude, or Copilot in last 3 months; can show what you directed AI to build)
End-to-end ownership (taken features from design to production, handled edge cases, monitored and iterated)

Nice to Have:

Experience with TypeScript + React and Go (our primary stack)
Built developer tools, dashboards, or workflow builders
Design sensibility (can create clean UIs without dedicated designer)

Why This Founding Role is Your Career Accelerant

Ship Fast, Learn Faster Every 90 days, you'll see your work come alive. Real features, real customers, real feedback—zero bureaucracy. While others wait for approval, you'll be shipping.

AI-Native From Day One Use next-gen AI orchestrators (Claude Code, Cursor, Codex) daily to build features 3-5x faster. Master the tools that ensure your career stays future-proofed.

Founding Team Ownership As a founding team member, your features define the product. Meaningful equity, product influence, and direct customer impact. This is the ground floor.
