Build lightweight processes, advise on org design, and drive culture initiatives in a fast-moving startup environment. ## Job description ## About Arena Intelligence Arena is the platform for evaluating how AI models perform in the real world. Founded by researchers from UC Berkeley's SkyLab, we're on a mission to measure and advance the frontier of AI for real-world use, and to build the foundation for everyone to understand, shape, and benefit from it. Tens of millions of people use Arena each month to evaluate how frontier systems handle the work they actually do. The preferences they share power the most transparent, rigorous, and human-centered evaluations in AI. Leading AI labs, enterprises, and independent researchers rely on our work and open datasets to understand how models behave in real workflows: agentic coding, creative generation, professional productivity, and beyond. We go beyond leaderboards and decompose what human experience reveals about AI, so models advance toward the work people actually do. We're a team of researchers, academics, builders, and creatives from UC Berkeley, Google, Stanford, and DeepMind. We seek truth, move fast, and value craftsmanship, curiosity, and impact over hierarchy. We're building a company where thoughtful, curious people from all backgrounds can do their best work together, in an office culture that radiates excellence, energy, and focus. ## About the Role Arena Intelligence is seeking an experienced People Operations Lead to design and scale HR programs, including onboarding, performance, and compensation, while acting as an HR business partner to leadership. The role involves building lightweight processes, advising on org design and employee relations, driving culture initiatives, managing compliance, and proactively addressing people infrastructure gaps, all within a fast moving startup environment. You'll work closely with leadership to create systems that scale, guide managers through critical people decisions, and shape the employee experience from the ground up. Reporting to the Head of People, you'll be a key partner in building a thoughtful, high performing organization. Success in this role requires someone who can move comfortably between strategic initiatives and hands on execution, bringing structure where it's needed without creating unnecessary process. If you're energized by building, enjoy solving people challenges in real time, and want meaningful ownership over how a company grows, we'd love to connect. You’ll - Build and evolve foundational programs including onboarding, performance management, compensation, career development, and other initiatives that support company growth. - Serve as a trusted advisor to leaders, providing guidance on team effectiveness, organizational design, employee relations, and people decisions. - Create lightweight systems and processes that improve consistency while preserving speed and flexibility. - Help shape an environment where employees can do their best work, driving initiatives that strengthen engagement, communication, and team health. - Ensure the fundamentals are operating smoothly, from policies and documentation to compliance and employee lifecycle management. - Partner with leadership on headcount planning, organizational structure, and evolving team needs. - Identify gaps before they become bottlenecks, building the frameworks and tools needed to support a growing organization. You’ll have - 6+ years of experience building People programs in an early stage or high growth environment where adaptability and execution mattered as much as expertise. - Strong HR business partnering skills and the ability to translate business goals into practical people strategies. - Sound judgment when navigating sensitive employee situations, balancing empathy with accountability. - A builder's mindset. You enjoy creating systems from scratch and improving them as the organization evolves. - Comfort operating in ambiguity and making progress without waiting for perfect information. - A practical approach to People Operations that focuses on outcomes rather than process for process's sake. - Familiarity with modern AI tools and a curiosity about how technology can improve internal workflows is a plus. ## What we offer - We offer competitive compensation and equity aligned to the markets where our team members are based. The base salary range will depend on the candidate’s permanent work location. - Comprehensive health and wellness benefits, including medical, dental, vision, and additional support programs. - The opportunity to work on cutting-edge AI with a small, mission-driven team - A culture that values transparency, trust, and community impact Come help build the space where anyone can explore and help shape the future of AI.
