About the Job

Requirements

At least 5 years of experience building and shipping production software, with senior-level ownership of non-trivial systems.
Strong full-stack range across a client stack and backend services, with the ability to work deeply on both client and server.
Hands-on experience with C# and/or Unity, or a credible record of rapidly learning these technologies through strong C++, game-client, graphics, or real-time systems experience.
Experience with real-time, low-latency, or high-concurrency systems such as multiplayer networking, streaming, matchmaking, or trading.
Ability to operate built systems, including testing, observability, and incident response.

Responsibilities

Ship end-to-end features across the Unity/C# client and backend game services, including table user experience, mini-games, application programming interfaces, and real-time state.
Improve client performance and stability for multi-tabling on desktop and mobile, including memory, frame budget, thermals, and reconnect/resynchronization.
Design and evolve real-time, low-latency gameplay services for table state, matchmaking, tournament flows, wallet/ledger, and event streaming.
Partner on fairness, integrity, and anti-cheat work, including random-number-generation correctness, hand-history accuracy, and an analytics pipeline that monitors anomalies.
Build for a regulated, real-money context and work alongside payments, know-your-customer, and geo-compliance systems without allowing that complexity to leak into gameplay.
Raise engineering standards through reviews, testing, observability, and on-call ownership for the surfaces assigned.

Desired Qualifications

Experience in poker, casino, social-casino, real-money gaming, iGaming, or sweepstakes.
Experience shipping live games or games-as-a-service to an audience using feature flags, staged rollouts, and A/B testing.
Unity performance profiling, memory or thermal optimization, or Electron desktop packaging experience.
Experience with multiplayer networking, matchmaking, or state synchronization at scale.
Experience with Kafka or Kinesis pipelines, hand-history, telemetry, or analytics.
Experience with Kubernetes, ArgoCD, or Jenkins.
Experience with payments/PSP routing, know-your-customer, geo-compliance, or fraud/integrity systems.
Being a poker player.

Salary Range: 225000 to 300000 (Currency: USD) (Pay period: per-year-salary)

At Bellota Labs, we’re building the next generation of interactive gaming experiences. Our newest product, WPTHome, is redefining how players engage with the World Poker Tour by creating a connected, engaging platform that brings the excitement and community of poker beyond the table. As a fast-growing startup backed by the World Poker Tour, we’re driven by innovation, world-class product development, and a passion for delivering exceptional player experiences.

We’re looking for a Senior/Principal Software Engineer to join our team and play a key role in shaping the architecture, design, and development of WPTHome. You’ll work alongside a talented engineering organization to build scalable systems, solve complex technical challenges, and help define the future of our platform. If you’re excited by the opportunity to build a product from the ground up and make a meaningful impact in a high-growth environment, we’d love to meet you.

Why this role is worth your time

Real product, real stakes, real players. ClubWPT Gold is a live, real-money (sweepstakes) poker + casino platform under the WPT brand — not a prototype. Your code ships to players multi-tabling for real prizes.

Genuinely hard engineering. Real-time table state, multi-tabling performance, client perf budgets across desktop (Electron) and mobile, provably-fair gameplay, and an event pipeline doing live hand analytics. This is netcode and low-latency systems work, not CRUD.

Greenfield leverage. We're mid-way through decoupling our platform into clean, independently-shippable services and a new back-office — so a senior engineer has room to set patterns, not just fill tickets.

Small US team, high ownership. You'll be one of a handful of senior full-stack engineers on Home. Scope is wide, decisions are yours to make, and impact is visible from day one.

Poker DNA welcome. If you play, you'll shape a product you understand better than most engineers ever could.

What you'll do

Ship end-to-end features spanning the Unity/C# client and backend game services — from table UX and mini-games to the APIs and real-time state behind them.

Improve client performance and stability for multi-tabling on desktop and mobile (memory, frame budget, thermals, reconnect/resync).

Design and evolve real-time, low-latency services for gameplay: table state, matchmaking, tournament flows, wallet/ledger, and event streaming.

Partner on fairness, integrity, and anti-cheat — RNG correctness, hand-history accuracy, and the analytics pipeline that watches for anomalies.

Build for a regulated, real-money context: work cleanly alongside payments, KYC, and geo-compliance systems without letting that complexity leak into gameplay.

Raise the engineering bar: reviews, testing, observability, and on-call for the surfaces you own.

What we're looking for

Must-haves

5+ years building and shipping production software; senior-level ownership of non-trivial systems.
Real full-stack range: strong in a client stack and in backend services (you don't need both to be Unity/C#, but you must be able to go deep on the client and the server).
Hands-on with C# and/or Unity, or a track record that makes picking them up fast credible (strong C++/game-client, graphics, or real-time systems background).
Experience with real-time / low-latency or high-concurrency systems (multiplayer netcode, streaming, matchmaking, trading, or similar).
Comfort operating what you build: testing, observability, incident response.

Nice-to-haves

Domain: poker, casino, social-casino, or real-money / iGaming / sweepstakes experience.
Live-ops / games-as-a-service: shipping to a live audience with feature flags, staged rollouts, and A/B testing.
Client depth: Unity performance profiling, memory/thermal optimization, or Electron desktop packaging.
Real-time systems: multiplayer netcode, matchmaking, or state sync at scale.
Data / eventing: Kafka / Kinesis pipelines; hand-history, telemetry, or analytics work.
Infra / CD: Kubernetes, ArgoCD, Jenkins.
Regulated domain: payments (PSP routing), KYC, geo-compliance, or fraud/integrity systems.
You're a poker player.

If you are excited to be part of a fast-growing team that is redefining the online gaming experience, we would love to hear from you. Join us at Bellota Labs and help shape the future of gaming innovation!
