## 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. You'll be the first face and voice our guests and visitors experience, setting the tone for every visit to our office. This is a high-visibility, in-person role: you'll own the front desk, our phone line, and the day-to-day rhythm of the space, including helping run our weekly Happy Hour. On a typical day, you'll greet guests, route calls, keep the office running smoothly, and solve small logistics problems before anyone else notices them. In quieter moments, you're encouraged to explore Arena's platform so you can speak to the product firsthand and bring that curiosity to conversations with guests and the team.

You'll Welcome Every Guest: Greet all guests promptly and warmly as they arrive, check them into our visitor management system, notify the appropriate employee/host that their guest has arrived, coordinate hand-off, offer guests a drink or light snack while they wait, and help guests get connected to WiFi, following our guest-access process as needed. Own the Front Desk Experience: Maintain a clean, organized, and welcoming reception area and conference rooms, with fresh touches like flowers and a pleasant scent, answer general guest questions or direct them appropriately, and help set up and clean up in-house lunch meetings. Run the Phones: Manage the company's main phone line, answering, screening, and routing incoming calls to the correct department or individual, taking and relaying accurate messages, and responding to general voicemail and phone inquiries. Support Happy Hour & Company Events: Set up the space ahead of Happy Hour and other events (furniture, signage, supplies, etc., as directed), assist with guest flow, check-in, and giving directions during the event, put together and hand out VIP guest goodie bags, and clean up and reset the space afterward. Keep the Office Running: Manage daily mail and package pickup, sorting, and distribution, and order and maintain front office/reception and conference room supplies. Keep Access Running Smoothly: Manage employee badge issuance and tracking, and coordinate with building security/facilities as needed.

You'll have

- Prior experience in a receptionist, front desk, or customer service role preferred.
- Strong verbal communication and interpersonal skills.
- Professional, welcoming, and composed in a client-facing role.
- Basic computer proficiency (email, scheduling tools, visitor management software).
- Highly organized with strong attention to detail.
- Ability to multitask in a fast-paced environment.
- Reliable and punctual, with flexibility to work extended hours on Happy Hour days (at least weekly; day/frequency may vary).
- Must be legally authorized to work in the United States.

Bonus Points

- Experience at an early-stage or fast-growing startup.
- Hospitality, events, or guest-services background (e.g., hotel front desk, restaurant host, catering/event staff).

## What we offer

- We offer competitive compensation aligned to the markets where our team members are based. The compensation range for each role is listed on its posting and will depend on the candidate's experience and 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.

Arena Intelligence provides equal employment opportunities (EEO) to all employees and applicants for employment without regard to race, color, religion, sex, national origin, age, disability, genetics, sexual orientation, gender identity, or gender expression. We are committed to a diverse and inclusive workforce and welcome people from all backgrounds, experiences, perspectives, and abilities.
