Fullstack Engineer - Data Platform
About The Position
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.

Responsibilities
- 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.
- Build anti-cheat and fraud detection server-side validation to catch faked gameplay, AFK farming, input spoofing, and manipulated recordings.
- Own the money path in Java / Spring Boot against Postgres for earnings, payouts, and status tracking (Tipalti) on an immutable, auditable ledger.
- Build admin tools in Next.js for managing users, reviewing sessions, and processing payments.
- Harden the full stack including mTLS between Cloudflare and origin, OIDC-authenticated Pub/Sub webhooks, encrypted-at-rest auth tokens, a pillar-encrypted secrets pipeline, and signed installers on GCP.
- Run the marketplace mechanics, including a cohort system for A/B testing task configs (pricing, duration, game selection).
- Build legal + compliance tooling for ToS versioning, sanctioned-country geofencing, GDPR DSR fulfillment, and worker-classification guardrails.
