Programmer, AI

Black Ember Games, an all-new development team within Xsolla, is looking for a Programmer for AI & Behavior to join our team building an asymmetrical multiplayer FPS using Unreal Engine5.

Our small internal team operates with an indie mindset, fueled by our passion for games. We're a diverse,  lively group dedicated to exploring new ideas within genres we love to play. We enjoy a hybrid work model, collaborating in our central Berlin and Novi Sad offices. Full remote is a possibility. 

As a Programmer for AI & Behavior, you will work first hand on making our NPCs (a crucial element of our design) feel realistic, playing a crucial role in developing the feel of the game. We want our NPCs to feel like an extension of the player and to surprise them with their abilities.  As a team with an indie mindset, we are not adherent to a stringent hierarchy and set of processes… if you know a better way to do something, bring that to the table, discuss, and set a new direction in collaboration with design and tech leadership.

• Implement and iterate on gameplay and AI behavior features — including NPC logic, movement, and decision systems — in Unreal Engine 5.
•  Integrate AI behaviors with core gameplay systems such as combat, navigation, perception, and interaction.
•  Contribute to tool development or debug visualizations to assist in testing and tuning AI behaviors.
• Collaborate closely with designers, animators, and artists to bring gameplay ideas to life and ensure AI behaviors align with design intent.
• Write clean, maintainable C++ and Blueprint code, following established architecture and coding standards.
• Debug and optimize AI and gameplay systems for performance and stability, identifying bottlenecks and proposing practical solutions.
• Communicate effectively with your team — raise risks early, give feedback on design feasibility, and help ensure features ship on time and at high quality.
• Particulate in code reviews, playtests, and QA sessions to help maintain consistency and polish across gameplay systems.

• 3–5 years of professional game programming experience, with at least one shipped title or major update using Unreal Engine 4 or 5.
• Proficient in C++ and comfortable working in both code and Blueprints for gameplay implementation and iteration.
• Hands-on experience with Unreal's AI systems — Behavior Trees, Blackboard, AI Controllers, Perception, and Navigation.
• Understanding of common AI architectures: state machines, behavior trees, perception systems, and movement logic.
• Solid understanding of 3D math and linear algebra, especially for movement, spatial reasoning, and targeting.
• Performance-minded developer: able to identify inefficiencies, profile gameplay logic, and optimize where needed.
• Comfortable with source control (Perforce) and collaborative workflows.
• Strong communication skills and ability to work effectively across design, animation, and engineering teams.
• Fluent English communication (written and verbal).

• Exposure to AI debugging or visualization tools (EQS, gameplay debug panels, etc.).
• Experience with Unreal Gameplay Ability System (GAS), MassEntity, or Chaos
• Familiarity with multiplayer gameplay and replication.
• Experience with live game updates or post-launch feature support.
• Knowledge of build pipelines (Horde, Jenkins) and general packaging workflows.

At Xsolla, we are passionate about providing a conducive environment for our team to thrive personally and professionally. Our Benefits Program caters to the physical, mental, and emotional well-being of our full-time employees.

Understanding the detrimental effects of burnout, we offer unlimited Flexible Time Off and 28 paid holidays each year. Personal and professional development is a cornerstone of our ethos at Xsolla. Each employee has a personalized career roadmap, developed in partnership with their manager, aligning individual and company goals.
