Responsibilities

  • Drive a small portfolio of complex features through initial creative input, stakeholder buy-in and alignment, consistent design reviews, and day-to-day execution.
  • Respond quickly to feedback with stable in-engine updates and iterate rapidly.
  • Provide design leadership within your feature area while contributing to broader game quality by mentoring others and sharing insights.
  • Reliably source ideas from around the studio, combining with own proposals and references to other products, in order to quickly solve and innovate within design challenges.
  • Work cross-functionally within and outside of your team to communicate and align on the work, tradeoffs and dependencies.
  • Radiate changes across the organization; set and mobilize against feature goals; and provide forward-looking direction aligned with greater design philosophy.

  • Quantitative and analytical, with past experience building and interrogating economy models and simulations to validate and align design decisions.
  • Deep understanding of the various components that come together to achieve an unparalleled player experience.
  • A self-starter who can align with the team's goals but isn't hesitant to create solutions of their own.
  • Capable of rapidly filtering large volumes of feedback into concrete and useful improvements.
  • Ability to flexibly design, implement, and iterate under tight deadlines & production constraints.
  • Well-played in the multiplayer PvP / Competitive Space and able to deconstruct what works and why.
  • Capability to abstract designs outside of single solutions into patterns and models of player behavior; providing options and flexible design solutions.
