Senior Gameplay Developer - Unity & Unreal | Game Systems & AI

Studios usually bring me in when gameplay is the bottleneck: combat or AI that doesn’t work yet, a progression system that needs building, or tools so designers can iterate without waiting on code. I’m a senior gameplay developer with 10+ years in Unity (C#, including 2D) and Unreal Engine 4/5 (Blueprints), released on iOS and Steam (Early Access). I work embedded in teams of 5–10 people, and my longest engagements have each run close to three years or longer. What I build: - Combat and AI: squad tactics with vision, targeting, shooting and cover; RTS-style unit commands; hostile creature AI - Progression and economy: crafting, base building, ranked ladder, seasonal rewards, in-game economies - Controls and mechanics: player controllers (2D/3D), driving and flying vehicles, weapons, placement and building systems, skill trees and branching dialogue - Gameplay UI and tools: deckbuilding and match flow, balance iteration, procedural generation, live-content updates, UI, SFX and VFX integration - Physics and animation integration, and profiling of core gameplay code Inside a team I also prototype features, fix bugs across the codebase and help prepare releases. Recent work: Destiny’s Divide (Fobia, Unreal, Steam Early Access, 140+ reviews), MERCS INC (Chicken Feet Digital, Unreal, upcoming on Steam), Expansion Beyond (Expansion Games, Unity, live on iOS; the only Unity developer in a 5–10 person team), DispoZone: Waste Wars (TroppoSoft, Unreal, prototype). Tell me the engine, team size and the gameplay problem, and I’ll say honestly whether I’m the right fit. European time zone, 20+ hours a week open now, more for the right long-term engagement.
