About Steel City Interactive

SCI was born out of passion for video games and boxing, with the ambition to create an authentic and exciting boxing game that does justice to the sport we love. What started as a fun prototype has grown into 'Undisputed', the first major boxing video game in over a decade.

SCI is a welcoming place for expression and open communication, where everyone has a voice. We're a diverse bunch, consisting of people with decades of games industry experience, graduates and talented individuals who come from other industries. We all bring knowledge and learn from each other.

Together we are driven by ambition to bring the world of boxing into a video game like never before.

The Role

You are a highly experienced AI Programmer, having worked on AAA titles within Unreal Engine, where you showcased your skills in NPC controls.

We're looking for a Senior AI Programmer to help shape the future of our game. In at the start as we pivot to UE5 you'll be responsible for the development of new character AI for our game, optimising and maintaining the AI systems of our product to AAA fidelity.

You will be working in collaboration with a highly talented, diverse team to create world-class character-based gameplay.

Responsibilities

• Design, implement, and maintain our AI systems using UE's native tools (State Trees, Blackboards, Perception systems) as appropriate, and extending them when needed.

• Create believable boxing opponents with advanced decision-making for attack, defence, ring movement, stamina management, and adaptive strategies.

• Integrate AI systems with the existing controls of the game to provide a balanced, responsive, and controlled challenge.

• Collaborate with designers to define, implement, and refine AI designs into manageable tools and reliable outcomes.

• Collaborate with the Gameplay, Tools, and Networking teams to ensure seamless integration with animation, physics, networking, and replay functionalities.

Knowledge, Skills & Experience

• Proven experience in AI programming for games.

• Experience with Unreal Engine 4 or 5 AI systems (Behaviour/State Trees, Perception strongly preferred).

• Familiarity with multiplayer AI considerations (e.g. determinism for rollback/match replays) is desirable.

• An eye for realistic opponent behaviour - the ability to discuss with designers and animators what makes a fight feel authentic.

• Proven experience with engine-level debugging and performance optimisation (Unreal Insights experience a must)

• Strong understanding of the underlying (UE) engine structures and techniques.

• Solid understanding of software architecture and engineering best practices.
