Software Engineer (Infrastructure)

Join us in pioneering the next generation of nuclear reactors! You'll leverage your software skills alongside engineers from a variety of disciplines to help model, simulate, design, and deploy advanced fission power technology. You will work at the forefront of the nuclear industry, developing novel techniques to reach new levels of safety, efficiency, and resiliency. Come be a part of powering the future with advanced fission power plants to provide clean, reliable, affordable energy.

Position Description

This role will be focused on enhancing our development processes, ensuring high-quality software delivery, and maintaining compliance standards. We support a variety of internal “customers” and use software and automation to ensure that other teams can do their jobs effectively. Oklo is a fast-moving startup, and our team is in the middle of building out our processes and capabilities. You will have the opportunity to help shape the trajectory of engineering infrastructure at Oklo. A nuclear background is not required, but a healthy curiosity and eagerness to learn are essential in this role.

Specific responsibilities may include 

Members of the Engineering Infrastructure team help enable software and infrastructure development across various domains. In this role you might:

• Develop and maintain CI/CD infrastructure
• Integrate data from engineering systems and tools (eg CAD, product lifecycle management, computational fluid dynamics, etc) into reactor design and simulation pipelines.
• Design, configure, and automate management of compute and data infrastructure.
• Build internal tooling to support local development, QA, and compliance workflows.
• Monitor and optimize system performance, troubleshooting issues as they arise.
• Contribute to design discussions, write RFCs, and document processes, configurations, and workflows.
• Collaborate across teams, balance competing priorities, and drive projects forward independently in the face of ambiguity.

Minimum Qualifications

We’d like to see a track record of the following, based on your past roles and experience:

• Bachelor's degree in Computer Science, Engineering, or equivalent industry experience
• A minimum of 3 years of experience in a Software Engineering role
• Fluency in Python, or significant Python experience plus fluency in a similar programming language
• Knowledge of software engineering fundamentals and best practices: testing, version control, system design, etc.
• Curiosity and passion for nuclear power, closing the nuclear fuel cycle, and sustainable energy generation.

Bonus Qualifications

Prior experience with our stack and tools is helpful, but not required:

• Cloud services and concepts, in particular AWS.
• Gitlab, especially Gitlab CI/CD.
• Containerization technologies (Docker).
• Infrastructure-as-code tooling (Ansible and Terraform).
• Compiled/performance-oriented languages (Rust).
• Linux/Unix system administration, virtualization technologies (VMWare), and core networking concepts.
• Experience building systems that integrate varied third-party tools and APIs.
• Experience working as a member of a distributed, remote team.

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.
