Who you are:

A startup person: You aren't driven by titles or hierarchy, and prefer efficiency to excess process. You don't need or expect to have a lot of guidance but you enjoy working in a fast-paced team. If you prefer the culture and feel of a large organization, that is great, but you likely won’t enjoy working with us! There is plenty of important work and plenty of good opportunities with organizations like that.

Motivated: You are self-motivated. You bring an enthusiasm to the team, and imbue a sense of passion that goes beyond clocking in and clocking out. This isn’t about a fake or arbitrary “pieces of flair” mentality or lack of work-life balance! It is about being a part of the vision and feeling a part of reaching team goals.

A team-player: Oklo genuinely is a team. We aren’t about taking credit for ourselves, and we aren’t about pushing blame to others. We do incredible things because we work as a team.

An excellent communicator: We need a person who is not only technically competent but also a clear and upbeat communicator.

Creative: Being creative means that when things fall outside clear scopes or processes or problems arise without clear solutions, you are able to identify it as well as invent ways to solve a problem or fill a need without micromanagement. The successful person in this job will not only be creative, but also enjoy being creative and solving open-ended problems which may change day-by-day.

Detail-oriented: This focus is a big part of excellence, consistency, and quality. Excellent grammar and spelling matter for both good communication as well as the image of the company that we put forward.

## Company Overview
- **One-liner**: Oklo is developing next-generation fast fission power plants to produce clean, reliable, and affordable energy at scale, starting with the Aurora reactor.
- **Entity Type**: Public (NYSE: OKLO) – completed SPAC merger with AltC Acquisition Corp. in May 2024.
- **Headquarters**: Santa Clara, California, USA
- **Founded**: 2013
- **Founders**: Jacob DeWitte (CEO) and Caroline Cochran

## Core Business
- **Industry**: Advanced nuclear energy / clean energy generation
- **Target Customers**: Utilities, large-scale energy consumers (data centers, industrial facilities), government (DOE, national labs), and communities seeking carbon-free baseload power.
- **Mission**: To deliver clean, reliable, and affordable advanced nuclear power to meet one of the planet’s most urgent challenges – abundant clean energy at a global scale.

## Products & Services
- **Aurora Powerhouse**: A compact fast fission reactor capable of producing up to 75 MWe of electrical power. Features inherent safety (walk-away safe, self-stabilizing), can run on fresh fuel or recycled nuclear waste, and is designed for cost-competitive deployment. Targets operation at Idaho National Laboratory (INL) from late 2027 to early 2028.
- **Advanced Nuclear Fuel Supply**: Oklo is developing fuel fabrication facilities under the DOE’s Fuel Line Pilot Projects to support its own reactors and the broader advanced reactor industry.
- **Critical Radioisotopes (via subsidiary Atomic Alchemy)**: Oklo’s fast reactors can produce life-saving medical and industrial radioisotopes as a co-product of fission.

## Market Standing
- **Valuation/Market Cap**: As of early 2025, market capitalization approximately ~$1.5–2.0 billion (fluctuating with public markets; latest SEC filings provide exact figures).
- **Key Metric**: Total funding raised prior to going public exceeded $50 million from private rounds. Post-SPAC, the company raised ~$300+ million from the merger trust and a PIPE. Annual revenue is not yet material (pre-revenue, pre-deployment).
- **Notable Investors/Partners**: DOE (Idaho National Laboratory site use permit, Reactor Pilot Program, fuel fabrication projects), AltC Acquisition Corp. (sponsor led by Sam Altman who also joined Oklo’s board), and institutional investors participating in the SPAC PIPE.
- **Growth Signals**: Secured DOE site use permit at INL (2019) and awarded EBR-II fuel for first Aurora core; completed NRC Phase 1 pre-application readiness assessment; selected for two DOE Reactor Pilot Projects; building three fuel-fabrication facilities; targeting first reactor operation 2027–2028. Team has grown significantly, with 52+ open roles as of mid-2025.

## Competitive Advantages
- **Proven Fast Reactor Heritage**: Liquid-metal-cooled, metal-fueled fast reactors have over 400 reactor-years of operating experience worldwide, including the EBR-II which demonstrated inherent safety and waste recycling for 30 years.
- **Waste-as-Fuel Capability**: Aurora can run on recycled nuclear waste (including from EBR-II), solving a major environmental challenge while reducing fuel costs – a capability only fast reactors offer.
- **Inherent Safety**: The reactor is self-stabilizing and self-controlling using passive natural forces, making it walk-away safe without need for active safety systems or backup power.
- **Cost Competitiveness**: Designed to achieve cost-competitive power across all generation technologies through compact design, simplified operations, and fuel flexibility.

## Strategic Focus
- **Deploy First Reactor**: Primary near-term goal is constructing and operating Aurora-INL at Idaho National Laboratory by late 2027–2028.
- **Licensing and Regulatory Pathway**: Continue NRC pre-application and formal licensing process for advanced reactor design; build regulatory precedent for fast reactors.
- **Fuel Supply Chain**: Establish advanced fuel fabrication capacity via DOE Fuel Line projects to secure fuel supply for Aurora and future customers.
- **Commercial Expansion**: Develop pipeline of additional Aurora deployments across the U.S. for utilities, data centers, and industrial customers seeking 24/7 carbon-free power.
- **Radioisotope Production**: Scale subsidiary Atomic Alchemy’s capability to produce critical medical isotopes as an additional revenue stream.
