We’re looking for a Level Designer to help construct unsettling, labyrinthine environments that promote tension, disorientation, and strategic exploration. In this role, you’ll design layouts that serve as the backbone of suspenseful gameplay, emphasizing player navigation, pacing, and psychological discomfort.

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.
• Structured Iteration Based on Feedback: Develop levels using a waterfall-inspired pipeline: concept, layout definition, design pass, and refinement—incorporating feedback at clearly defined stages.
• 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.
