Senior Systems & Infrastructure Engineer

Who We're Seeking

We are seeking a generalist Senior Systems & Infrastructure Engineer to work on our core infrastructure across Linux systems, networking, storage, and cloud environments. This is a hands-on, high-impact role in a startup setting, working closely with the CTO to design, operate, and evolve reliable, secure, and scalable Infrastructure.

You will be responsible not just for keeping systems running, but for helping shape how infrastructure is architected, built and operated as the company and our product service grows.

Key Responsibilities

• Infrastructure Ownership: Own the day-to-day operation and long-term evolution of core infrastructure, partnering with the CTO on architecture and strategy while balancing reliability, security, cost, and delivery speed.
• Linux Systems Engineering: Design, deploy, secure, and operate Linux systems across on-prem and cloud environments, leading automation, performance tuning, patching, and complex incident response.
• Networking: Design, secure, and operate IPv4 network architectures including routing, VLANs, NAT, and firewalling across physical and virtual environments, resolving performance and connectivity issues.
• Storage, Backups & Data Protection: Architect and operate resilient storage, backup, and disaster recovery solutions, ensuring data integrity, availability, retention, and tested recovery across critical systems.
• Network File Systems: Architect and manage shared file systems using NFS and Samba, defining access models, permissions, and performance for multi-user and multi-service environments.
• Cloud Infrastructure (AWS and/or others): Design, operate, and optimise cloud infrastructure primarily in AWS, managing VPCs, IAM, compute, storage, networking, cost control, and on-prem integration.
