If you’re passionate about building emotionally charged spaces and understand how spatial design influences gameplay, we’d love to hear from you.

Responsibilities

• Design Structured, Tension-Filled Environments: Create detailed level layouts that encourage player separation, increase navigational pressure, and support claustrophobic, high-stakes exploration.

• Establish Gameplay Flow and Encounter Spaces: Integrate player movement, pacing beats, and moment-to-moment tension into the layout, ensuring both challenge and navigability.
• Design Alternate Layouts (e.g., Nightmare Versions): Plan spatial and functional variations of environments to support dual-world gameplay, psychological disorientation, and dynamic threat strategies.
• Collaborate Cross-Functionally: Work closely with game designers, tech artists, and level artists to ensure technical feasibility and fidelity to narrative and gameplay goals.
• Support Navigation-Driven Storytelling: Design spatial logic, transitions, and layouts that align with the story experience, while leaving visual storytelling and asset placement to the Level Art team.
• Contribute to Playtesting Strategy: Provide design intent documentation and support structured testing phases to validate level usability and gameplay goals.

Ideal Candidate Has…

• 3+ Years of Experience: In level design, ideally in horror, immersive sims, survival games, or other tension-driven genres.
• Unreal Engine 5 Expertise: Strong proficiency in level building, Blueprints, lighting, and performance considerations.
• Deep Understanding of Player Psychology: Especially how space, sound, and ambiguity can evoke discomfort, dread, and curiosity.
• Collaborative Work Style: Comfortable coordinating with art and tech disciplines to ensure designs fit technical and aesthetic goals.
• Comfort with Waterfall Design Methodology: Able to work through defined phases of layout development and feedback cycles.
• Experience With Navigation-Oriented Level Challenges: Familiarity with building maze-like, layered environments for single-player or co-op navigation under pressure.

Bonus Points For…

• Experience with:
  • Environmental storytelling or puzzle design.
  • Co-op/multiplayer level balancing.
  • AI pathing and dynamic spatial triggers.
• Knowledge of:
  • Neuroarchitecture and sensory-affect design principles.
  • Horror cinematography or sound design.
