    Job description

    Kigen enable businesses to grow their Internet of Things rapidly through the SIM, eSIM and iSIM technologies and are pushing the boundaries in the industry. Working with a number of high-profile customers globally, our growing business is excited to be expanding our team in Belfast.

    Help keep the world's SIMs and eSIMs running — securely, reliably, and at scale. At Kigen, our platforms and infrastructure underpin SIM and eSIM services used across the globe. We're looking for a Platform / Infrastructure Engineer to own and maintain the systems — spanning our on-premises data centre estate and public cloud — that keep production stable, compliant, and always on.

    What you'll be doing

    • Administer and secure our on-premises data centre estate alongside public cloud environments (AWS, GCP or similar).
    • Own OS patching, certificate lifecycle, and vulnerability remediation across the estate.
    • Build and maintain configuration management and automation (Ansible or similar) for consistent, repeatable infrastructure changes.
    • Support containerised workloads (Docker, Kubernetes or similar).
    • Maintain logging, monitoring, and observability tooling (ELK stack or similar).
    • Manage secure file transfer services (MFT/SFTP or similar) for partner and customer data exchange.
    • Configure and troubleshoot load balancing (F5 or similar) and monitor the virtualised estate.
    • Own developer environments and artifact repositories (Nexus or similar).
    • Take part in an on-call rotation as a first responder for production incidents.
    • Provide hands-on support at our Dublin data centre, with travel as required.

    What we're looking for

    • Hands-on experience with virtualisation and on-premises server infrastructure (VMware ESXi or similar).
    • Strong, proven experience with Linux.
    • Experience with configuration management / infrastructure-as-code (Ansible, Terraform or similar).
    • Experience with logging and monitoring stacks (ELK or similar).
    • Understanding of containerisation and orchestration (Docker, Kubernetes or similar).
    • Good grasp of security concepts, including vulnerability management and certificate/PKI lifecycle.
    • Experience with git and artifact repositories (Nexus or similar).
    • Willingness to travel to our Dublin data centre as required.
    • Strong communication skills and comfort working autonomously.
    • Willingness to participate in an on-call rotation.

    Nice to have

    • Experience administering public cloud infrastructure (AWS, GCP, Azure or similar) at scale.
    • Scripting ability (Python, Bash or similar).
    • Exposure to cloud cost optimisation / FinOps practices.
    • Experience in a regulated or security-sensitive industry (telecoms, SIM/eSIM or similar).
    • Familiarity with ITIL or similar change/incident management processes.

    What are Kigen’s benefits?

    At Kigen we like to ensure our people are well supported and rewarded for what they do. We offer a

    competitive salary and benefits package, along with a great flexible working culture. This role would be fully remote within Northern Ireland, but with plenty of opportunity to meet and collaborate with colleagues. 

    We are an Equal Opportunity Employer and do not discriminate against any employee or applicant for employment because of race, colour, sex, age, national origin, religion, sexual orientation, gender identity, status as a veteran, and basis of disability or any other federal, state or local protected class.
