About Roam

Roam is looking for strong engineers to help us build the first true Game Super App: an AI native, mobile game engine that lets anyone create, publish, monetize and play studio quality 3D multiplayer games with their friends.

Our goal is to finally let everyone make games quickly. Similar to how TikTok turned everyone into creators through easy to use good video edit tools, we'll turn every person into a studio quality game author without the need for any technical skills.

Users can make any world, objective, art, level, multiplayer, etc can be made in seconds. Since starting couple months ago, we have:

• Locked in >1 000 gaming & livestream creators (100 K–10 M followers each) who will launch Roam-made titles to an aggregate reach of 250 M+ fans.
• Assembled a tight team of SAIL researchers, ex-Voodoo / Supersonic studio founders who have already shipped 100+ mobile game hits, and built AI infra for numerous companies.
• Raised an unannounced round from a great VC, who are investors in Pokemon Go, Twitch, SpaceX, Polymarket and founders of similar companies.

Role: Senior Unity Engineer

You will help build the core of our mobile engine and toolset in Unity, enabling anyone to author 3D multiplayer experiences in seconds. This role demands both deep technical expertise and a passion for making powerful game-creation tools accessible to non-technical users.

Responsibilities

• Architect and implement a seamless bridge between Unity runtime and our native iOS frameworks
• Build and optimize real-time 3D systems for world generation, networked multiplayer, AI-driven gameplay, and live streaming
• Design and maintain reusable Unity UI components and editor extensions to accelerate feature iteration
• Profile and tune performance across CPU, GPU, memory, and network to guarantee sub-60 fps on a wide range of devices
• Collaborate with design and AI teams to integrate machine-learning tools directly into Unity workflows
• Own end-to-end feature development—from design spec through testing, analytics, and live deployment

You might be a good fit if you have

• 5+ years of professional Unity development experience, shipping at least one 0→1 game or tool
• Deep knowledge of C#, ECS or DOTS, Scriptable Render Pipelines, and the Unity Editor API
• Proven track record of optimizing large-scale Unity projects for performance and stability
• Strong product instincts for usability, authoring workflows, and tool UX
• Experience building multiplayer game systems (state sync, rollback, matchmaking)

Strong candidates may also have

• Background in AI/ML integration or procedural content generation in Unity
• Led a small engineering team or mentored junior developers
• Open-source Unity tools or published Unity Asset Store packages

Compensation

• Gameplay engineers get paid a minimum base salary of $50,000. The pay goes up to $150,000 a year base if you are truly exceptional. This is in addition to 0.1% - 0.5% equity.
