About the Position
Senior/ Principal Full-Stack Engineer (B2C Anti-Cheat POC) (Remote)
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.
Responsibilities
-
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
-
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.
-
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
-
Prepare for Core Integration
- Build architecture that can later integrate into QuintAce core
- Ensure modular, scalable service boundaries
- Support future multi-platform extension
Requirements
-
Required
- 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.
We Offer
- Remote Work: Fully remote position
- Employment Type: Full-Time
