Job description

• Nerve is MGI’s platform to enable human feedback within our research engine. Today, Nerve 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, Nerve 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
• 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
