About the role

  • Mob Entertainment is seeking a Senior Systems Engineer to join the team supporting development of one of our upcoming Unreal Engine projects.
  • This role is designed for a highly experienced engineer who can own core gameplay and engine-adjacent systems end-to-end, set technical direction, and raise the bar for the rest of the engineering team.

Responsibilities

  • Design, build, and maintain core gameplay systems and frameworks used across the project, ensuring they're robust, scalable, and easy for other engineers to extend.
  • Develop and maintain custom Unreal Engine plugins to support project-specific tooling and gameplay needs.
  • Architect and implement multiplayer/networked gameplay systems, including replication strategy, network optimization, and debugging desync or performance issues.
  • Own technical decisions for systems under your purview, balancing production needs, performance, and long-term maintainability.
  • Partner with designers and gameplay programmers to translate gameplay and design intent into well-structured, tunable systems.
  • Identify architectural risks and technical debt early, and drive solutions before they become blockers.
  • Mentor junior and mid-level engineers through code review, pairing, and ongoing technical guidance; help grow the team's overall skill level.
  • Debug and resolve complex, systemic issues reported during production, QA, and post-launch, using Jira to track and prioritize work.
  • Document system architecture, workflows, and design patterns in Confluence to support team-wide understanding and onboarding.
  • Participate in and help lead code reviews, design discussions, and sprint planning as part of a cross-functional development team.

Requirements

  • 8+ years of professional experience in game development, or 2+ shipped AAA titles, with a focus on systems or gameplay programming.
  • Strong knowledge of systems and framework design (data-driven architecture, modular/extensible system design, gameplay frameworks).
  • Strong gameplay programming knowledge, with a track record of shipping gameplay systems in Unreal Engine.
  • Experience designing and building Unreal Engine plugins.
  • Solid, hands-on multiplayer/networked gameplay experience (replication, RPCs, network optimization, debugging networked issues).
  • Excellent proficiency in both C++ and Blueprints within Unreal Engine.
  • A genuine passion for mentoring other engineers and helping them grow.

Preferred qualifications

  • Some Unreal Engine core/engine-level knowledge (engine source, low-level systems beyond typical gameplay code).
  • Prior leadership experience (leading a team, owning a discipline, or acting as a technical lead on a project).
  • Experience shipping systems that scaled or evolved significantly beyond MVP.
  • Familiarity with performance profiling and optimization within Unreal Engine.
  • Familiarity with source control tools (e.g., Perforce) in a game production pipeline.
  • Passion for horror games, narrative-driven experiences, or the Poppy Playtime franchise specifically.

Benefits

  • medical, dental, and vision insurance
  • 401(k) matching
