About the job

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.
  • Recent experience in at least one 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, enterprise, or similarly complex systems.
  • Strong programming ability in at least one of Ruby (Rails), Go, or similar systems languages, with the willingness and ability to work across multiple languages and codebases.
  • Hands-on experience with infrastructure automation tools such as Ansible and orchestration platforms such as AWX.
  • Strong experience with observability systems, including the Grafana stack: Prometheus, Loki, Mimir, and Grafana Alloy.
  • Familiarity with low-level telemetry and infrastructure protocols such as 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 CI/CD pipelines, including GitHub Actions and self-hosted runners.
  • Strong understanding of operational reliability concepts, including monitoring, alerting, capacity planning, and incident response.
  • Ability to work closely with Site Reliability Engineering, 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 Site Reliability Engineering 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 Site Reliability Engineering 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 on Rails and Go, contributing to a consistent and maintainable engineering ecosystem.
  • Develop and maintain automation workflows using Ansible and AWX.
  • Support CI/CD-driven operational tooling, including GitHub Actions and self-hosted runners.
Desired Qualifications
  • Kubernetes Certified Administrator certification.
  • Completion of cloud-native observability training courses or attendance at industry conferences in this field.
  • CompTIA+ Security qualifications.
  • LPI/LPIC certification.

About the company

Radiant builds and operates utility-scale AI infrastructure to deliver sovereign AI cloud compute through owned data centers, long-term capital, and proprietary software.

Simplify's Take

What believers are saying

  • Feb. 24, 2026 launch created a $1.3 billion platform with rolled-in Ori investors.
  • Radiant claims direct access to Brookfield's $100 billion AI infrastructure program.
  • Ori Global AI Cloud keeps on-demand bare metal, GPU instances, and fine-tuning offerings live.

What critics are saying

  • Radiant depends on Brookfield funding and contract wins to justify its capital-intensive model.
  • NVIDIA chip supply concentration and rapid obsolescence can strand Radiant's data-center investments.
  • Execution failure on sovereign contracts or deployment delays destroys the utility-scale thesis entirely.

What makes Radiant unique

  • Feb. 24, 2026 merger fused Ori software with Brookfield-powered infrastructure.
  • Radiant pairs powered land, long-term capital, and sovereign-cloud software under one operator.
  • NVIDIA DSX, Blackwell, and GB200 NVL72 make Radiant a purpose-built AI factory platform.
