You will be responsible for the core simulation logic that powers our partners’ interactive experiences.

An ideal candidate is passionate about games, enjoys tackling a wide range of technical challenges, and has a track record of delivering great player and customer experiences across different areas of game development.

WHAT YOU’LL DO:

• C++ Migration: Identify and migrate under-performing GDScript systems to C++ for improved performance and maintainability.

• ECS Implementation: Design and implement simulation logic using the Flecs ECS framework, ensuring efficient data locality and scalability.

• Performance Optimization: Profile simulation workloads, identify bottlenecks, and apply multithreading techniques to optimize frame time.

• Serialization & State: Develop robust serialization and state replication systems for distributed simulation support.

• Technical Design: Collaborate with the team to break down complex simulation requirements and deliver practical, high-performance solutions.

WHAT WE VALUE:

• ECS Experience: Proficiency with Entity Component System architectures, preferably with Flecs.

• Mathematical Fundamentals: Solid understanding of linear algebra, physics, and simulation mathematics.

• Engineering Excellence: A commitment to writing clean, testable, and efficient code.

• Problem Solving: Ability to debug complex state issues and optimize performance-critical code paths.

• Breadth of Experience: Comfort working across different systems and disciplines within game development, with a generalist mindset.

• Team Collaboration: Strong communication skills and the ability to work collaboratively with engineers, designers, producers, and project leads.

• Problem Solving: A proactive and thoughtful approach to identifying, diagnosing, and resolving technical challenges.

• Passion for Gaming: A genuine enthusiasm for games and a desire to help create engaging, high-quality experiences for players.

• Interest in Learning: Curiosity and eagerness to learn new technologies, engines, and practices to remain adaptable and effective.

WHAT YOU MAY ALSO HAVE:

• GDScript Experience: Familiarity with Godot/GDScript to assist in migration efforts.

• Distributed Simulation: Experience with networking, state synchronization, or multi-server architectures.

• Multithreading: Advanced knowledge of concurrency, lock-free data structures, and parallel processing.

• Mentorship Skills: Experience supporting or mentoring less experienced developers as they build new skills.

• Stakeholder Communication: Experience working with internal or external partners to gather feedback, provide technical input, and solve problems collaboratively.
