About the role

The Systems Administrator will be responsible for day-to-day of our global multi-tenant VOIP platform.  The platform runs across 4 continents and has a very fast-growing user base (1500% per annum).

Responsibilities will include:

Day to day administration of:

  • 30+ CentOS 7 VMs running in Azure and AWS, hosting real-time SIP call processing,
    Several AudioCodes SBCs, liaising with the vendor’s support and performing upgrades,
    Azure PaaS resources (SQL, AppService, DNS, Azure Storage, CosmosDB etc).

Collaborating with colleagues to:

  • Ensure that security policies are implemented, including managing access, patching servers, managing external penetration testing, and taking an active part in maintaining the ISO27001 information security accreditation,
  • Respond to incidents,
  • Build new capabilities or remediate existing ones.
  • Recording and reporting capacity, availability, service-affecting incidents, planning changes to improve reliability and resilience.

Any other tasks as reasonably required.

Please note that we will require you to be on-call to address any platform issues 1 week in three (this will include evenings and weekends).

Requirements

Skills and experiences that will help you succeed:

  • Strong verbal and written communication skills – ability to work in English is a must if English isn’t your native language.
  • Expertise in networking. Comfortable with UDP, TCP, TLS. Familiarity running network captures and debugging unusual TCP scenarios.
  • Experience with server monitoring tools such as Zabbix, nagios, PRTG.
  • Expertise in and opinions on cloud environments such as MS Azure and Amazon AWS.
  • Server configuration management tools such as Ansible, Puppet or Chef.
  • Automated provisioning frameworks such as CloudFormation and Terraform.
  • Broad and deep knowledge of various server platforms, and how to scale and configure each for reliability and automation.

We do not expect you to have SIP experience, but a demonstrable ability to pick up new skills is a must as you will need to quickly gain a working understanding of SIP message flows.

As a fast growing company there is the opportunity to grow with it in a variety of directions, including DevOps automation if desired.

Qualities and behaviours we’re looking for:

  • A true pair of ‘safe hands’ inspiring confidence that will keep the promises we make to our partners, e.g. a combination of “been there, seen it, bought the t-shirt” and “how could we do this quicker, better, cheaper”.
  • Striking the perfect balance between passion, perfection and practicality – doing great stuff but knowing when to stop and just get it out the door.
  • Preference for working in a fast-moving, constantly changing environment.
  • Love for, and curiosity about, new technologies and methodologies and how they shape the world.
  • Experience of working in a startup or scale-up with an understanding that everyone needs to roll their sleeves up and get involved.
