About General Intuition
General Intuition is the frontier lab for acting in space and time. We build large action models and world models that can perceive, predict, and act across virtual and physical environments. General Intuition builds on the strength of Medal, the world's largest and fastest-growing platform for gaming clips, where millions of gamers capture, share, and discover new games every year. We recently raised $320M at a $2.3B valuation led by Khosla Ventures with participation from General Catalyst, Eric Schmidt, and Jeff Bezos, to discover the next generation of real-world intelligence.
The Role
MGI's platform enables human feedback within our research engine. Today, the platform is a desktop app that allows users to browse tasks, record gameplay, and get paid, backed by services that manage sessions, verify uploads, and process payouts. Next, the platform will power ever more diverse tasks such as watching and correcting the model, collecting data of humans operating in simulation, and real-world teleoperation tasking.
We're spinning it up now and need someone to own it end-to-end. You'll lead the engineering and think like an owner about where the platform goes - we need extremely high ownership and ruthless optimization for speed.
What We're Looking For
Frontend React/TypeScript (Zustand, Vite), admin in Next.js

What We're Looking For
- You integrate with our C#/.NET game recorder over WebSocket JSON-RPC - screen capture, game detection, input capture, video encoding - and debug across the Electron↔recorder boundary when things break; you're at home with the Electron main↔renderer split and IPC (deep Node.js is enough if Electron is new).
- You build anti-cheat and fraud detection - server-side validation that catches faked gameplay, AFK farming, input spoofing, and manipulated recordings. Workers are paid to beat you; your job is to make it impossible.
- You own the money path in Java / Spring Boot against Postgres - earnings, payouts, and status tracking (Tipalti) on an immutable, auditable ledger where correctness is non-negotiable (migrations, query optimization, transaction isolation).
- You build the admin tools in Next.js for managing users, reviewing sessions, and processing payments - productive day one in TypeScript + React (Zustand, Vite).
- You harden the full stack - mTLS between Cloudflare and origin, OIDC-authenticated Pub/Sub webhooks, encrypted-at-rest auth tokens (Electron safeStorage/DPAPI), a pillar-encrypted secrets pipeline, and signed installers - on GCP (Cloud Run, Cloud SQL, GCS, Pub/Sub, Secret Manager), reading Terraform and debugging deploys as you go.
- You run the marketplace mechanics - a cohort system for A/B testing task configs (pricing, duration, game selection) to find the price point that maximizes training-data volume and quality per dollar.
- You build the legal + compliance tooling - click-wrap ToS versioning, sanctioned-country geofencing, GDPR DSR fulfillment, and worker-classification guardrails that keep the contractor relationship defensible.
