This is a unique role that blends fast-paced gameplay prototyping, hands-on technical leadership, and a front-row seat to learning innovation.

We’re looking for a Senior Unity Gameplay Engineer to prototype a 4-player first person game about surviving a nuclear reactor as systems fail and pressure escalates. You’ll own the critical path for gameplay—building and iterating on the core experience while keeping the codebase clean and shippable. You’ll elevate junior engineers through high-signal code reviews and clear feedback, and collaborate with a dynamic team and partner studios. Beyond the game, you’ll help shape a new model of education that bridges learning with working, turning real production tasks into individualized growth paths.

What you'll do

  • Prototype, implement, and iterate on core co-op gameplay systems (first-person interactions, team objectives, dynamic events, and tension/pacing systems, etc.)
  • Define lightweight architecture patterns that keep rapid prototypes flexible but sane
  • Lead a team of junior engineers: break down tasks, unblock devs, and provide technical direction
  • Run code reviews and uphold standards on readability and performance
  • Help shape our AI-powered individualized learning system by contributing ideas and sharpening the feedback loop

Required qualifications

  • 5+ years of professional Unity/C# experience.
  • Shipped at least 2 commercially released titles (any genre/platform) or equivalent production experience with a live/released product.
  • Deep, practical Unity gameplay engineering experience (systems built end-to-end, iteration on feel, debugging, basic profiling).
  • Practical multiplayer networking experience (replication and authority fundamentals, latency-aware design, diagnosing desync and bandwidth issues). Experience with Coherence is a plus.
  • Comfortable providing technical direction: code reviews, task breakdown, and mentoring/unblocking junior engineers.
  • Pragmatic decision-making in fast-moving prototype environments; able to balance speed with maintainability.
  • Strong async communication, ownership, and collaborative problem-solving.

What we offer

  • A startup-style environment with a supportive, high-trust culture
  • Creative freedom and real influence over the game’s direction and execution
  • Exposure to a variety of projects as we expand our partnerships
  • Flexible hours—you decide when you work, with light coordination for reviews/syncs
  • A strong learning culture, with access to mentor office hours and guest lectures
  • Make tangible impact on the next generation of game developers

Additional Details:

  • Location: Remote
  • Type: Contract, 20 hrs/week
  • Compensation: $50-$100/hr
About
RealXP Lab

At RealXP Lab, we’re building more than just an education platform—we’re exploring how continuous learning and meaningful work can go hand-in-hand. In a world shaped by rapidly advancing technology, especially AI, it’s time to rethink the traditional notion of a "job" and create systems that support lifelong learning and value creation.

We began with a simple goal: to experiment with such a system by applying it to the game industry. Meaningful work shouldn’t be reserved only for those who’ve mastered their craft—though they certainly deserve it—or for those fortunate enough to land in the right job. By democratizing access, we can foster a more equitable and humanistic future.

 

Why join us

  • Startup-style environment. Join a supportive, fast-moving team with candid collaboration, and low-bureaucracy execution.
  • Creative freedom. Bring ideas, make calls, and directly shape the game’s direction and moment-to-moment feel.
  • Wide exposure. As we expand our studio partnerships, you’ll have opportunities to touch new projects and genres.
  • Flexible hours. Work when you’re sharpest, with light coordination around reviews and syncs.
  • Strong learning culture. Participate in mentor office hours and guest lectures alongside a team that’s always leveling up.
  • Shape the future of learning. Help create a new model of education that bridges learning with work.

 

Join a team of talented individuals who are passionate about games, innovation, and making a real impact.
