WE ARE GAME MAKERS
Who we are:
We are a diverse team of developers driven by a passion for our art, united by our core values and inspired by a culture of inclusivity to build amazing games that thrill players everywhere. We pursue growth and innovation in an environment of safety and trust. Our culture is built on the belief that the more varied voices in our collective will strengthen our team and our games. We are looking for our next teammate who will raise our bar and make us better.
What we need:
31st Union is looking for a Senior Gameplay Engineer to develop our Player Bots - AI agents that stand in for human players in our AAA free-to-play, cross-platform action game. Using C++, Unreal Engine 5, and our in-house utility AI framework, you will make bots that fight, traverse, loot, and team up convincingly enough that players second-guess whether they're facing a human. The same bots power mode backfill and automated testing at scale.
Responsibilities:
Develop combat behavior: target prioritization, hero-appropriate weapon and ability use, movement, and disengagement
Develop humanization: tunable aim, reaction time, and error models across difficulty levels
Develop macro behavior: team cohesion, traversal, pacing, events, looting, and progression
Extend our utility AI framework: new behaviors, scoring, and tuning
Keep bot populations performant: throttling, suspension, and LOD
Extend bots as automated test clients, from feature tests to match-scale load tests
Build bot evaluation tooling: debug visualization and playtest metrics
Partner with design to tune behavior through playtests
Who you are:
5+ years of gameplay or game AI engineering on shipped action games
Strong C++ and Unreal Engine fluency, including AI controllers, navigation, and EQS
Utility AI or comparable decision-making architectures
AI in networked multiplayer: client/server authority, prediction, dedicated servers
Humanlike combat AI: aim and error models, reaction time, believable movement
Optimizing many concurrent agents: LOD and tick throttling
Nice-to-Haves:
Player bots in a competitive shooter
Unreal Engine 5, StateTree, and the Gameplay Ability System
Control systems (e.g., PID controllers) and input simulation
Automated test clients and load testing
The pay range for this position in California at the start of employment is expected to be between $108,900 and $161,160 per year. However, base pay offered is based on market location, and may vary further depending on individualized factors for job candidates, such as job-related knowledge, skills, experience, and other objective business considerations.
Subject to those same considerations, the total compensation package for this position may also include other elements, including a bonus and/or equity awards and eligibility to participate in our 401(K) plan and Employee Stock Purchase Program.
Regular, full-time employees are also eligible for a range of benefits at the Company, including: medical, dental, vision, and basic life insurance coverage; 14 paid holidays per calendar year; paid vacation time per calendar year (ranging from 15 to 25 days) or eligibility to participate in the Company's discretionary time off program; up to 10 paid sick days per calendar year; paid parental and compassionate leave; wellbeing programs for mental health and other wellness support; family planning support through Maven; commuter benefits; and reimbursements for fitness-related expenses. Ontario only: The use of Artificial Intelligence is not being used to screen candidates. The position is for an existing vacancy.
