Job Description

Posted on: March 17, 2026

Senior/ Principal Full-Stack Engineer (B2C Anti-Cheat POC)Node.js / React

Remote | Full-Time

About the Role

We are building a B2C Anti-Cheat product surface that exposes integrity signals, trust scores, and suspicious behavior indicators to end users.

This role is focused on execution — building the first production-grade POC that turns anti-cheat outputs into real, user-facing product experiences.

You will work closely with the Data / Anti-cheat team and integrate detection outputs into scalable backend services and intuitive frontend dashboards.

This is a hands-on role with direct impact on product delivery.

What You’ll Do1️⃣ Build the Anti-Cheat Application Layer (POC First)

  • Develop backend services (Node.js) to consume integrity signals from data systems
  • Design APIs that serve trust score, risk indicators, and evaluation results
  • Build real-time and batch processing flows for B2C hand evaluation
  • Ensure reliability and clean data boundaries

2️⃣ Deliver B2C Product Surfaces (React)

  • Player integrity dashboard
  • Trust score visualization
  • “Why this score?” explanation UI
  • Suspicious signal indicators
  • Evaluation result page

Focus: clarity, transparency, and product usability.

3️⃣ Integrate with Data / Anti-Cheat Systems

  • Work with data engineers & ML teams
  • Integrate model outputs into serving layer
  • Handle ingestion, validation, deduplication
  • Maintain version control and logging

4️⃣ Prepare for Core Integration

  • Build architecture that can later integrate into QuintAce core
  • Ensure modular, scalable service boundaries
  • Support future multi-platform extension

What We’re Looking ForRequired

  • 5+ years full-stack engineering experience
  • Strong Node.js backend development
  • Strong React / frontend architecture
  • Experience working with data-heavy systems
  • Experience building APIs and dashboards
  • Comfortable working in ambiguous 0→1 environments
  • Strong ownership mindset

Preferred

  • Trust & safety / fraud / risk product exposure experience
  • Gaming or fintech background
  • Experience working with ML-driven systems

Why This Role Matters

This is the first version of a product that makes anti-cheat transparent to players.

You’re not building detection models —

you’re building the product layer that makes integrity visible, understandable, and actionable.

POC → Core Product → Platform Integration.
