Job Description:

G.Digital are back with one of our favourite partners in the Tech for good space who are in need of a Senior Linux Wizard to oversee a new exciting project.

You’ll be joining a small, highly skilled team working on a large-scale, embedded server platform — built on Ubuntu, running on real hardware, and powering production systems used by thousands.

This isn’t a role buried in abstraction — you’ll be close to the metal, solving real problems with real consequences.

What You’ll Do

• Maintain and optimise Ubuntu-based Linux systems running in a private cloud environment.
• Monitor, troubleshoot, and improve performance across systems and services.
• Manage production databases (PostgreSQL, Cassandra, Redis, Kafka) with a focus on reliability and scalability.
• Work on network infrastructure — including WireGuard tunnels, BGP configuration, and general network troubleshooting.
• Contribute to internal tooling (AMIs, automation, monitoring) and help shape the direction of infrastructure projects.
• Occasionally provide out-of-hours support as part of a shared rotation ( All within normal working hours Monday - Friday)

What We’re Looking For

• Deep experience running Linux systems in production — especially Ubuntu.
• Confidence in managing, tuning, and troubleshooting relational and distributed databases.
• Strong understanding of networking concepts — experience with VPNs, routing, and security best practices.
• Comfortable working independently, but with strong communication and documentation habits.
• Ability to collaborate with engineers across backend, DevOps, and infrastructure teams.

What We Offer

• Remote-first working environment (UK-based).
• Modern, straightforward hiring process (no take-home tests or endless rounds).
• A team that values trust, autonomy, and getting things done properly.

Hiring Process

• Intro Call – 20 minutes with the hiring manager to understand your experience and interests.
• 90 minute interview including – Focused conversation on Linux internals, debugging, and systems architecture.
• Team Session – Meet with peers to explore collaboration fit.
• Final Conversation– Discuss the company, role, and your expectations.
