Company mission
To create sustainable, efficient, and planet-friendly data centers and other energy-intense environments.
Role
Who you are
- Strong DevOps or platform engineering background in complex cloud-native environments
- Proven experience with infrastructure as code and large-scale deployment automation
- Hands-on experience with Kubernetes-based delivery and operational workflows
- Strong understanding of CI/CD design, release safety, configuration management, and secrets handling
- Experience managing multi-component platform deployments across environments
- Comfortable working with both vendor software and internally developed services
- Familiarity with GitOps principles and declarative deployment patterns
- Strong troubleshooting mindset across build, deployment, runtime, and infrastructure layers
- Able to improve both developer velocity and operational reliability
- Experience in platform, private cloud, or infrastructure-heavy environments is a strong plus
- Able to independently own major automation, deployment, or environment-management initiatives from design through production rollout
What the job involves
- Mission: Build and operate the engineering automation platform that enables repeatable, secure, and scalable deployment of the GPU cloud platform across environments
- You will be responsible for core parts of the automation backbone behind the platform
- You will design and maintain the tooling, pipelines, and infrastructure-as-code foundations used to deploy vendor components, platform services, and supporting environments consistently and at scale
- This role is central to turning a complex software design into an operable engineering system
- You will work across Kubernetes, Terraform, Kustomize, GitHub Actions, secrets management, storage, and observability, and ensure that deployments are reproducible, secure, and maintainable
- You understand that DevOps in this environment goes beyond pipeline ownership
- It means building the delivery mechanisms for a platform composed of multiple integrated services, including orchestration, identity, metering, storage, observability, messaging, and cloud infrastructure components
- You will independently deliver major automation and deployment capabilities, improving operational quality, and helping teams adopt reliable deployment patterns within an existing platform direction
- Design, build, and maintain CI/CD pipelines for platform components and supporting services
- Manage infrastructure automation using Terraform and related IaC tooling
- Implement GitOps-style deployment workflows for Kubernetes-based platform services
- Standardize and automate environment provisioning across development, staging, and production
- Maintain developer environments and improve engineering productivity through better tooling and automation
- Automate deployment of vendor and platform components such as Kubernetes, databases, storage, observability, identity, and messaging systems
- Manage secrets and configuration workflows using centralized secret management practices
- Improve deployment reliability, traceability, rollback safety, and operational consistency
- Work closely with backend and platform engineers to turn software designs into repeatable deployment patterns
- Contribute to platform operability, monitoring, and release engineering standards
- Technical Stack:
- Terraform
- Kustomize
- GitHub Actions
- Kubernetes
- Docker
- Bitwarden Secrets Manager
- HashiCorp Vault
- Ceph / Rook
- Observability stack integration
- Infrastructure automation and release engineering practices
Our take
Developments in the AI sector have increased the strain on data centres and chips, generating more heat from their processes than ever before. Cooling methods using air and water are not keeping pace with the amount of energy needed to support AI. Submer is on a mission to build data centres and processing plants that are as sustainable as they are efficient.
Submer’s eco-friendly product for data centres and chip processing is built from a coolant of non-flammable, biodegradable and synthetic liquid that physically acts in the same way as water. The racks for servers are stored and operate from within a smart container which further lessens the heat produced by data centres. Submer’s range of products even allows for the coolant to be reused via a heat exchanger.
It’s an inspired solution for an increasingly pressing problem. Data centres are going nowhere, yet the vital need for greener energy solutions puts pressure on these industries. It’s unsurprising then that Submer has raised considerable funding that is being channelled into the expansion of its product. Server component manufacturers are even beginning to build their products to be compatible with Submer’s, indicating the eagerness with which the industry is welcoming the solution.
