Requirements
  • A degree in Computer Science or Software Engineering, or equivalent experience.
  • Six to eight years of experience in infrastructure engineering, DevOps, Site Reliability Engineering, and/or software engineering roles, with a strong focus on operational systems.
  • Proven experience in at least one recent DevOps or software engineering role building or maintaining production infrastructure tooling or platform systems.
  • Experience working in large-scale or distributed infrastructure environments, such as hyperscale or enterprise systems.
  • Strong programming ability in at least one of Ruby with Rails, Go, or similar systems languages, with the ability to work across multiple languages and codebases.
  • Hands-on experience with Ansible and AWX.
  • Strong experience with observability systems, including Prometheus, Loki, Mimir, and Grafana Alloy.
  • Familiarity with SNMP and syslog.
  • Experience working with Kubernetes or similar orchestration platforms in production environments.
  • Understanding of API design and integration patterns, particularly REST-based services and service-to-service communication.
  • Experience building and maintaining continuous integration and continuous delivery pipelines, including GitHub Actions and self-hosted runners.
  • Strong understanding of monitoring, alerting, capacity planning, and incident response.
  • Ability to work closely with SRE, Platform Engineering, and infrastructure teams to translate operational needs into maintainable software systems.
Responsibilities
  • Design, build, and evolve internal tooling and observability platforms that support large-scale infrastructure operations across distributed environments.
  • Develop systems that turn high-volume telemetry, including logs, metrics, and events, into actionable insight, improving visibility, alerting quality, and operational decision-making.
  • Translate SRE reliability requirements into scalable, production-ready software solutions, including automation for incident detection, prevention, and remediation.
  • Drive automation across infrastructure operations, reducing manual effort in environment provisioning, cluster onboarding, inventory management, and lifecycle workflows.
  • Build tooling for capacity management, performance testing, benchmarking, and automated collection and analysis of results.
  • Contribute to Continual Service Improvement initiatives by identifying operational inefficiencies and delivering durable engineering solutions.
  • Work closely with SRE and infrastructure engineering teams to embed observability and reliability into core platform workflows.
  • Interface with Platform Engineering teams to ensure tooling aligns with broader orchestration and infrastructure strategy.
  • Integrate and extend existing systems written in Ruby with Rails and Go, contributing to a consistent and maintainable engineering ecosystem.
  • Develop and maintain automation workflows using Ansible and AWX.
  • Support continuous-integration and continuous-delivery-driven operational tooling, including GitHub Actions and self-hosted runners.
Desired Qualifications
  • Kubernetes Certified Administrator certification.
  • Cloud-native observability training courses or attendance at industry conferences in this field.
  • CompTIA Security+ qualifications.
  • LPI or LPIC certification.

Radiant builds and operates utility-scale AI infrastructure to deliver sovereign AI cloud compute through owned data centers, long-term capital, and proprietary software. It runs AI factories that provide scalable, resilient compute for governments, enterprises, and telecom providers, enabling rapid deployment of AI workloads at scale. After merging with Ori Industries, Radiant integrates distributed AI software with its hardware to form a global AI utility that lowers energy costs and reduces dependence on centralized clouds. Its goal is to create a secure, scalable AI platform that serves distributed locations worldwide, balancing land, capital, and software to support large-scale AI applications.

Simplify's Take

What believers are saying

  • Secures $100B Brookfield pipeline enabling global utility-scale AI factory deployment.
  • Merger with Ori integrates distributed AI software backbone accelerating telco and sovereign workloads.
  • Long-term contracts lock revenue across five-year chip cluster life with investment-grade customers.

What critics are saying

  • Kaleidos 1MW microreactor lacks operational testing, threatening 2028 commercialization timelines.
  • Ten+ nuclear microreactor competitors risk squeezing Radiant out within 18–24 months.
  • $525M funding and $1.81B valuation create existential pressure to deliver reactors by 2028.

What makes Radiant unique

  • Vertically integrates capital, land, power, compute, and proprietary software for AI factories.
  • First NVIDIA DSX-engineered infrastructure company built from ground up for integrated AI compute.
  • Behind-the-meter power model co-locates AI factories with 5GW live and 45GW renewable capacity.
