About the Role
Tessera Labs is looking for an experienced Office Manager to own the day-to-day operations of our New York office. This is a hands-on, high-visibility role for someone who thrives in a fast-paced environment, takes pride in creating a well-run and welcoming workplace, and enjoys wearing many hats. You'll be the backbone of our office experience — from keeping day-to-day operations running seamlessly to planning and executing high-impact internal and external events.
This role is ideal for someone with strong instincts for anticipating needs before they become problems, who takes ownership without needing to be asked twice, and who genuinely enjoys helping a team run smoothly.
What You'll Do
Manage all aspects of office operations, including ordering and stocking supplies, kitchen/pantry management, and general office upkeep
Coordinate furniture upgrades, installs, and office layout changes, working with vendors and building management as needed
Partner with operations team on the planning and execution of company events, team offsites, holiday parties, and other employee experience initiatives
Partner with Communications, Go-to-Market, and executive leadership to coordinate high-visibility external events, including executive dinners, customer roundtables, investor gatherings, and conference-related activations attended by CIOs, venture capitalists, customers, and strategic partners
Serve as the primary point of contact for facilities issues, vendor relationships, and building management
Provide administrative and executive support as needed, including scheduling, coordinating meetings, and handling correspondence
Manage office budget for supplies, events, and operational needs
Own the onboarding experience for new hires from a workplace/logistics standpoint (desk setup, equipment, welcome materials)
Anticipate office needs proactively and troubleshoot issues before they escalate
Jump in wherever needed — priorities shift quickly here, and this role requires flexibility and a "no task too small" mindset
Help maintain a positive, organized, and energizing office culture
What We're Looking For
5+ years of experience in office management, administrative support, or executive support
Demonstrated success planning and executing both internal employee events and executive-facing external events
Experience partnering with senior leaders and cross-functional teams—including Communications, Marketing, Go-to-Market, or Executive Leadership—to deliver polished, high-touch experiences
Experience managing office logistics: ordering/stocking supplies, coordinating furniture installs and upgrades, vendor management
A high level of drive, autonomy, and ownership — you don't wait to be told what to do
Strong team player with excellent interpersonal skills and a positive, can-do attitude
Comfortable shifting priorities quickly in a dynamic, fast-moving environment
Excellent organizational skills and attention to detail
Strong written and verbal communication skills
Must be able to work onsite in our New York City office
Nice to Have
Experience supporting a growing startup or high-growth company
Familiarity with office management tools (e.g., booking systems, expense tools, HRIS platforms)
Experience with light project management or cross-functional coordination
