Roblox Game Developer (Lua/Luau)

Job Type: Temporary Contract

About the role

We are building polished, high-performance Roblox experiences for a global player base. You will own gameplay systems from concept to live deployment — writing clean, efficient Luau code across both client and server, designing multiplayer interactions, and maintaining live games post-launch.

What you'll do

• Design and implement core gameplay systems — movement, combat, progression loops, inventory, currency, and social features using Lua/Luau in Roblox Studio
• Build and maintain server-side logic: DataStore (player data persistence), RemoteEvents/RemoteFunctions, and server-authoritative game state
• Architect client–server separation correctly — preventing exploit surfaces with server-side validation and filtering-enabled checks
• Implement in-game economy systems: Developer Products, Game Passes, virtual currency flows, and reward structures
• Optimize game performance — minimise network replication overhead, manage memory, and keep server FPS stable under concurrent load
• Build responsive, cross-device UI using Roblox's GUI framework (Frame, ScreenGui, TextButton, etc.) with clean UX
• Set up and operate live-ops features: timed events, A/B testing hooks, analytics telemetry, and patch workflows
• Collaborate with designers and artists to integrate 3D assets, animations, and audio into playable experiences
• Write modular, maintainable code using OOP patterns, ModuleScripts, and Knit/Aero/custom frameworks
• Conduct code reviews, write technical documentation, and mentor junior developers

Must-have skills

• 2–5 years hands-on Roblox development with demonstrable shipped games or experiences
• Strong Lua/Luau proficiency — closures, coroutines, metatables, OOP patterns, error handling
• Deep understanding of Roblox's client–server model, Workspace, Lighting, StarterGui, ServerStorage, ReplicatedStorage
• DataStore and DataStore2 / ProfileService — PCalls, retry logic, versioning, data migration
• RemoteEvents and RemoteFunctions — correct usage, rate limiting, and exploit prevention
• Multiplayer systems — replication, lag compensation, and secure server-authoritative logic
• Performance optimisation — Part streaming, LOD, script profiler, Micro-Profiler usage
• Experience with Roblox monetisation APIs (MarketplaceService, Developer Products, Game Passes)
• Familiarity with Git or Rojo/Argon for version control and team workflows

Good-to-have skills

• Experience with community frameworks: Knit, AeroGameFramework, or self-built service architectures
• Knowledge of TypeScript-to-Luau transpilation via roblox-ts
• Basic 3D modelling or rigging familiarity (Blender) — not required, but reduces friction
• Understanding of F2P game design, player retention, and in-game economy balancing
• Analytics integration (Roblox built-in, or custom telemetry via HttpService to an external sink)
• Anti-cheat and exploit mitigation patterns
• Previous experience shipping a Roblox title with 10K+ concurrent players
• Background in Unity (C#) or Godot as a secondary engine

What we look for in a portfolio

• Links to playable Roblox games — we will play them and review scripting quality, UI polish, and performance
• Code samples demonstrating DataStore persistence, RemoteEvent architecture, or a game economy system
• Evidence of shipped live games, not just prototypes
• Any open-source Roblox modules on GitHub or Roblox DevForum
