Islamabad, Islamabad, Pakistan RocketDevs Full time $60,000 - $120,000 per year

RocketDevs empowers software engineers in remote and economically disadvantaged regions by connecting them with global tech opportunities. Our mission is to bridge talent and opportunity, enabling developers to thrive while contributing to a more inclusive and connected tech community.

We're hiring a Senior C++ engineer to lead the emulator / core-game integration work for a browser-forward, skill-based contest platform built around classic retro games. This role focuses on adapting open-source emulators for time-limited, pay-to-play contest modes, automated scoring, anti-cheat, and integration with a WordPress-based site and a custom web app.

This is an
external role
for one of our
client companies.

Why this is interesting

You'll be working on a high-volume micro-entry gaming product that combines low-level systems work with web integration: optimizing emulators for browser delivery (WebAssembly/emscripten flows), ensuring deterministic scoring under strict time limits, and building robust anti-cheat measures so thousands of short contest runs are fair and auditable.

What you'll own

  • Evaluate and adapt existing open-source emulator codebases for web delivery (porting / modifying C++ emulators to run in-browser where needed).
  • Implement deterministic scoring instrumentation and a secure way to record/upload scores from ephemeral contest runs.
  • Design and implement anti-cheat measures (game-state isolation, tamper-detection, server-side validation, replay proofs).
  • Work with the front-end/devops team to pipeline WebAssembly builds, optimize runtime performance, and support controller/keyboard input mapping.
  • Integrate emulator scoring and contest lifecycle with the platform backend (APIs for contest creation, entries, payouts, and admin notifications).
  • Provide technical guidance for ROM handling, permitted code modifications, and safe/legal reuse of open-source components.
  • Produce clear, maintainable C++ code and documentation; participate in design reviews and candidate interviews when needed.

Must-have skills & experience

  • 3+ years professional C++ development (modern C++ preferred).
  • Proven experience reading and modifying emulator or game engine code, or experience with systems that require deterministic reproduction of runtime state.
  • Experience porting C++ to WebAssembly (emscripten) or similarly shipping native code to the browser.
  • Strong knowledge of multithreading, low-latency I/O, memory management, and performance profiling.
  • Solid understanding of security/anti-tamper techniques and practical anti-cheat strategies.
  • Comfortable integrating native components with web backends (REST/GraphQL, secure score submission, authentication flows).
  • Strong debugging skills and familiarity with reverse-engineering/debugging tools (symbol analysis, runtime tracing).
  • Excellent communication — able to explain low-level tradeoffs to full-stack and product teams.

Nice-to-have

  • Previous work on emulators (NES/SNES/arcade/DOS-era titles) or contributions to retro-gaming projects.
  • Experience with controller input APIs and mapping (XInput, HID, browser Gamepad API).
  • Familiarity with WordPress integration patterns and creating plugin/extension hooks.
  • Experience with cloud-hosted game backends, Redis, message queues, or real-time leaderboard systems.
