About the role
Key responsibilities & impact- Design, implement, and operate the next generation of secure management access for people, services, and automated operational workflows
- Build secure, least-privilege, and auditable access paths to production systems, including management gateways, SSH-based access, authentication, authorisation, and related controls
- Improve the resilience, usability, traceability, and operational safety of privileged access
- Collaborate with security, platform, and operations teams to ensure the target architecture works during normal operations and incident pressure
- Contribute to incremental migration of existing systems and workflows to the new access architecture, with rollback and continuity considerations
- Redesign the secure connectivity foundation for an approximately 10,000-system production fleet
- Engineer resilient, scalable connectivity patterns between central platform services and distributed Linux hosts, virtual machines, and related infrastructure
- Develop automation, observability, and tooling that make fleet-wide changes safe, repeatable, measurable, and recoverable
- Improve foundations for remote management, configuration delivery, software lifecycle management, diagnostics, and incident response
- Operate and evolve core platform services, including management access, remote connectivity, time synchronisation, Nginx, Redis, and supporting Linux-based infrastructure
- Own systems through their lifecycle: design, implementation, testing, rollout, operation, incident learning, and continuous improvement
- Use Git-based development, CI/CD, infrastructure-as-code, and automated testing to deliver reliable changes
- Collaborate across engineering and Mission Control operations to turn production requirements into practical platform capabilities
- Contribute to operational documentation, runbooks, and architectural decision-making
- Evaluate and adopt tools and approaches that improve security, speed, and reliability
Requirements
What you’ll need- Solid practical knowledge of Linux systems, service management, permissions, processes, filesystems, and troubleshooting
- Strong understanding of TCP/IP, DNS, TLS, SSH, routing fundamentals, and systematic network troubleshooting
- Experience with, or a strong desire to learn, authentication, authorisation, privileged access, VPN or remote-access services, and secure operational practices
- Experience with scripting or programming in Python, Go, Bash, Perl, or a comparable language
- Experience with Git, code review, CI/CD, and automated or configuration-driven deployments
- Hands-on experience using agentic AI workflows such as GitHub Copilot, Claude Code, Cursor, or similar
- Relevant technical training, a degree, or equivalent practical experience
- Relevant technical education in Computer Science, Information Technology, Systems Engineering, or equivalent practical experience
- Demonstrated interest in designing, automating, and operating reliable systems at meaningful scale
- Desirable: experience with HashiCorp Boundary, bastion or jump-host architectures, PKI, SSH certificate authorities, or comparable access-management technologies
- Desirable: experience with OpenVPN or other remote-access and connectivity technologies
- Desirable: experience with configuration management, infrastructure as code, Helm, Kubernetes, or GitOps
- Desirable: experience operating high-availability or stateful services such as Redis, Nginx, NFS, DNS, or database-adjacent services
- Desirable: experience with RPM packaging, Linux software release processes, or large-scale fleet configuration and rollout
- Desirable: experience with monitoring, logging, alerting, tracing, or production incident response
- Ability to work confidently in Linux and deepen skills in platform engineering, networking, security, and automation
- Ability to contribute to implementation, testing, automation, and safe rollout while learning end-to-end service ownership
- Ability to ask good questions, learn quickly, document work, and work carefully with production systems
- Ability to explain technical risks, decisions, and operational consequences clearly to technical and non-technical stakeholders
- Ability to work constructively across security, platform, software engineering, and operations teams
Benefits
Comp & perks- Full-time employment at 80–100%
- Hybrid work arrangement
- Close support from experienced colleagues
- Learning and development toward independent ownership of services and components
- Opportunity to work on strategic engineering initiatives at fleet scale
