ILIAS Solutions; Diegem; On-site; EUR 70,000 - 110,000; Full time

Job summary

ILIAS Solutions is building a Kubernetes-based platform to deploy its defense software. You will shape cluster design, networking, storage, RBAC and multi-tenancy while keeping today’s environment healthy.

You will own end-to-end architecture, production readiness, and security considerations across the stack, from design to live operations, enabling teams to take ownership and ship securely.

Qualifications

• Built Kubernetes environments from scratch and operated them in production.
• Experience taking containerized workloads to Kubernetes in production environments.
• Strong Linux knowledge and troubleshooting across the stack.
• Familiarity with GitOps and infrastructure automation practices.
• Proven ownership of production systems including observability, upgrades and backup/recovery.

Responsibilities

• Design and build the Kubernetes foundation for the next generation platform.
• Own architecture, networking, storage, RBAC and multi-tenancy topics.
• Ensure security, auditable delivery, SBOMs and provenance from development to prod.
• Create guardrails and automation to empower engineering teams.
• Collaborate across architecture, engineering, operations and security to run in production.

Job description

Opportunity

How Will We Deploy the Next Generation of ILIAS Products?

Our software can operate in isolated or fully air-gapped defense environments, where remote access becomes extremely limited after installation. Product updates still need to be deployed reliably and securely, without depending on manual intervention.

That is the challenge you will help us solve.

Today, ILIAS products run on Docker Swarm. We are now designing and building a new Kubernetes-based platform for the next generation of ILIAS products.

You join while that foundation is still taking shape. Together with the team, you help shape cluster design, networking, storage, RBAC and multi tenancy, while keeping today's environment healthy.

Build what comes next while understanding what needs to keep running today.

Meaningful Work

The Technology Behind Readiness

ILIAS helps defense organizations connect operations, maintenance, logistics, training and configuration to understand and prepare their operational readiness.

Your work sits underneath that capability. The Kubernetes foundation you help build will support how ILIAS products run, recover and remain secure across different defense environments.

What you build at platform level helps ILIAS support readiness at operational level.

Your Mission

You combine architecture with deep technical ownership.

You work across Kubernetes, Linux, Docker, Docker Swarm, networking, storage, RBAC, observability, capacity, backup and recovery. GitOps and automation make changes reproducible, traceable and reversible.

When something behaves unexpectedly, you follow the problem through the technical stack until you understand the cause. Building the architecture is only part of the job. You need to understand it deeply enough to keep it healthy in production.

Security is part of that thinking from the start. Identity, secrets management, policy enforcement, SBOMs, signing and provenance contribute to a trusted and auditable software delivery chain.

You also create guardrails and automation that allow engineering teams to take ownership themselves. A strong foundation should enable teams rather than make you their gatekeeper.

Build it. Understand it. Keep it alive.

What You Bring

You have built Kubernetes environments from scratch and operated them in production.

You know what happens when architecture becomes reality because you have owned systems when they worked and when they did not.

You bring:

• Deep, hands-on Kubernetes expertise
• Strong Linux knowledge
• Deep experience with Docker and Docker Swarm
• Experience moving containerized workloads towards Kubernetes
• Advanced troubleshooting across the technical stack
• GitOps and infrastructure automation experience
• Production ownership, including observability, upgrades, backup and recovery
• Strong system thinking
• Experience in regulated or security-sensitive environments

Experience with air-gapped infrastructure, accreditation, defense, government, STIG or FIPS adds valuable context.

Our environment includes technologies such as Keycloak, OpenBao, Mend, SonarQube, Nexus, PostgreSQL, MinIO and Apache Spark. Experience with some of them will make it easier to get started, but we don't expect you to know them all.

What matters most is your in-depth knowledge of Kubernetes, your ability to understand the complete system, your experience in demanding environments and the way you work with others.

Build Your Future with ILIAS

You join while important engineering decisions are still ahead.

That gives you the opportunity to help shape the Kubernetes foundation, bring it into production and see how your choices perform in real operational environments.

You work across architecture, engineering, operations and security. Along the way, you gain experience with technical challenges ranging from cloud infrastructure to isolated defense environments where remote access can be extremely limited.

As part of Patria Group, ILIAS combines the focus of a specialized defense software company with the reach of an international defense and technology organization.

As the foundation develops, your experience and influence can grow with it.

Build the foundation while helping shape what comes next.
