Oklo is an advanced fission technology company focused on developing compact, commercially viable power plants. The organization employs roughly 120 people and has expanded its workforce by more than one-quarter through 32 recent hires while keeping attrition to a minimum. This steady growth underscores Oklo’s ongoing investments in engineering talent and operational support as it moves toward commercial deployment of its microreactor technology.
Engineering is Oklo’s largest team with 61 employees, accounting for a little over half of the company’s total headcount. Business Management and Marketing & Product follow, each with 11 employees, while Sales & Support and Finance & Administration house 10 team members apiece. Smaller groups such as Operations (5), Risk/Safety/Compliance (4), Legal (3), Program & Project Management (2), and an "Other" category (3) round out the organizational chart. Recent hiring has been weighted toward technical and customer-facing roles, reflecting the company’s need to advance reactor development and prepare for commercialization.
Oklo’s workforce is geographically dispersed, with a core presence in California and a sizable remote contingent. San Francisco hosts the largest on-site team at 18 employees, and nearby hubs such as San Jose (5), Los Angeles (4), Santa Clara (4), and San Diego (3) create a strong West Coast cluster. Outside California, headcount is spread across Denver (4), New York (5), Washington, DC (2), and Salt Lake City (2), while the majority—approximately 73 employees—operate from other locations, illustrating a flexible, distributed staffing model that supports collaboration across time zones.
