Infrastructure Manager

About Euphoria:

Euphoria Telecom is a South African telecommunications company providing cloud-based business communication solutions to companies across the country.

We design, build and operate our own national voice platform, which means our infrastructure team works on systems that are genuinely business-critical. We’re looking for an experienced Infrastructure Manager who wants to take ownership of a complex production environment, lead a capable technical team and help shape the next generation of our platform.

About the role:

Our multi-tenant cloud PBX supports businesses across South Africa and runs across a hybrid environment of on-premise infrastructure and AWS.

The estate includes Asterisk PBX and carrier infrastructure, Linux and Windows application environments, MySQL platforms, networking and monitoring systems, alongside a new generation of infrastructure currently being commissioned.

As Infrastructure Manager, you’ll take end-to-end ownership of the reliability, security, performance and evolution of this environment.

This is a hands-on leadership role for someone who understands what it means to run infrastructure where downtime has an immediate customer impact.

What you will be responsible for:

• Owning uptime, capacity, resilience and change management across our PBX, SIP, database, application and API environments.
• Leading monitoring and observability across the estate.
• Managing and evolving our hybrid AWS and data-centre architecture, including networking, connectivity, identity and access.
• Improving deployment, configuration management and infrastructure automation across Linux and Windows environments.
• Leading platform upgrades and migrations, including the modernisation of existing systems.
• Managing infrastructure logging, auditing, backup and recovery capabilities.
• Owning infrastructure security, including credential management, least-privilege access, attack-surface reduction and telecom fraud controls.
• Leading a small infrastructure team, including the on-call function, technical standards and documentation.
• Working closely with our CTO and development teams on infrastructure architecture, platform evolution and technical risk.

What we’re looking for:

• Extensive experience in infrastructure, systems or platform engineering, with significant experience leading a team or owning a production estate.
• Proven responsibility for a 24/7 production environment where outages have a direct customer impact.
• Strong experience managing a hybrid environment spanning on-premise infrastructure and public cloud.
• Deep Linux and Windows Server administration experience, including IIS and PowerShell.
• Strong AWS experience, particularly EC2, VPC, RDS/Aurora, S3 and IAM.
• Solid networking knowledge across routing, firewalls, VPNs and DNS.
• Hands‑on MySQL operational experience, including replication, upgrades, backup and recovery.
• Strong monitoring and observability experience.
• Experience with configuration management, CI/CD and infrastructure automation.
• Strong Bash and PowerShell capability.
• Sound technical judgement, particularly around production changes, risk and understanding the potential blast radius when something goes wrong.

Experience with the following would be valuable, but isn't essential:

Asterisk · SIP · VoIP infrastructure · OpenSIPS/Kamailio · telecom fraud controls · Keycloak/OIDC · Terraform · Docker/Kubernetes · ITIL · ISO 27001 · POPIA · South African telecoms or ISP environments

What we offer:

• Market-related salary
• Optional Retirement Annuity
• Group Life Cover
• Modern offices
• Generous leave policies
• Regular company events
• Breakfast, lunch and snacks provided at the office

If you’ve spent your career running infrastructure that genuinely needs to stay up - and you’re ready to take ownership of an environment rather than simply administer a piece of it - we’d like to hear from you.
