Fullstack Engineer - Data Platform

Game Devs of Color Expo; New York (NY); On-site; USD 150,000 - 210,000; Full time

Job summary

General Intuition seeks a platform engineering lead to own the desktop and cloud components end-to-end. You will integrate a C#/.NET recorder, implement anti-cheat measures, and own the Java/Spring Boot payouts against a Postgres ledger. You’ll build Next.js admin tools in TypeScript/React and tighten security across GCP.

You will work across the stack from Electron to cloud services, optimizing performance and data integrity while shipping with fast iterations and clear ownership.

Qualifications

• Must integrate with our C#/.NET game recorder via WebSocket JSON-RPC and debug across Electron-recorder boundary.
• Build anti-cheat and fraud detection with server-side validation to ensure integrity of gameplay data and payments.
• Own money path in Java/Spring Boot against Postgres, including earnings, payouts, and status tracking on an auditable ledger.
• Develop admin tools in Next.js with TypeScript + React (Zustand, Vite) for user sessions and payments.

Responsibilities

• Harden full stack: mTLS, OIDC-authenticated Pub/Sub webhooks, encrypted tokens, and secure installers on GCP.
• Design and optimize cohort-based A/B testing for task configs and pricing to maximize data quality and volume.
• Collaborate across frontend/backend teams to deliver end-to-end platform ownership.

Job description

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.

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

• 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.

Our Stack

Frontend React/TypeScript (Zustand, Vite), admin in Next.js

• Desktop Electron + C#/.NET recorder (WebSocket JSON-RPC)
• Backend Java/Spring Boot + Postgres (Flyway)
• GCP (Cloud Run, Cloud SQL, GCS, Pub/Sub, Secret Manager), Cloudflare, GitHub Actions, Terraform
• Media: ffprobe, CRC32C, NVENC/AMF
• Payments: Tipalti
