Job description

Crusoe is building the World’s Favorite AI-first Cloud infrastructure company. We’re pioneering vertically integrated, purpose-built AI infrastructure solutions trusted by Fortune 500 companies to power their most advanced AI applications. Crusoe is redefining AI cloud infrastructure, with a mission to align the future of computing with the future of the climate. Our AI platform is recognized as the "gold standard" for reliability and performance. Our data centers are optimized for AI workloads and are powered by clean, renewable energy.

Be part of the AI revolution with sustainable technology at Crusoe. Here, you’ll drive meaningful innovation, make a tangible impact, and join a team that’s setting the pace for responsible, transformative cloud infrastructure.

About This Role

At Crusoe, our Site Reliability Engineering (SRE) team plays a pivotal role in ensuring the reliability and performance of our infrastructure. SRE at Crusoe is dedicated to detecting, analyzing, and preventing issues to maintain high Service Level Agreement through Service Level Indicators (SLIs) and Service Level Objectives (SLOs). Through automation and proactive remediation, our SREs not only resolve common errors automatically but also advise various engineering teams in building resilient code. We prioritize anticipating and resolving issues before they impact our customers, conducting thorough post-mortems, and driving continuous improvement. Our customer‑centric approach ensures that clients always have access to the virtual machines they depend on. Join us to help build and maintain the robust systems that power Crusoe's innovative solutions.

What You’ll Be Working On

As a Senior Site Reliability Engineer at Crusoe, your day begins with a review of overnight alerts and system performance metrics to ensure everything is running smoothly. We operate close to the hardware, so many of these will be novel hardware failures on cutting‑edge equipment that are challenging to diagnose and automate. You will collaborate with your team in a morning stand‑up meeting to discuss ongoing projects, recent incidents, and priorities for the day. Your tasks might include automating routine processes, analyzing system logs, and developing tools to enhance our monitoring capabilities. You’ll spend part of your day working closely with software engineers, advising on best practices for resilient code and reviewing changes before deployment. Regularly, you will engage in incident response drills, post‑mortems, and root cause analysis sessions to learn from past issues and prevent future ones. Throughout the day, you will stay focused on maintaining high SLIs and SLOs, ensuring that our infrastructure remains robust and reliable for our customers. By day's end, you will document your work, share insights with your team, and plan for the next day's challenges, always with a customer‑centric mindset.

What You’ll Bring to the Team

• 5+ years of professional SRE experience
• 3+ years of experience contributing to architecture and design (architecture, design patterns, reliability and scaling) of new and current systems
• Bachelor's Degree in Computer Science or related field, or 8+ years relevant work experience
• Solid understanding of infrastructure design, including the operational trade-offs of various designs
• Experience writing high quality code with at least one programming language (Python, Go, or similar)
• Experience with Unix/Linux environments
• Experience with TCP/IP and network programming
• Experience with information security best practices
• Excellent communication skills

Bonus Points

• Excited to work with cutting edge AI training & inference hardware and networks
• Experience running large, mission‑critical storage systems / NVMe over Fabric
• Experience building with modern infrastructure tools such as Docker, Kubernetes, Ansible, Cloud Formation, Terraform
• Experience building with modern CI/CD practices and build systems, such as GitLab CI/CD, CircleCI, GitHub Actions
• Experience with logging, monitoring and alerting systems and tools

Benefits

Crusoe also offers a competitive benefits package designed to support financial security, health, and overall well‑being, including pension contributions, private health and dental insurance, income protection, life assurance and more.
