As a Site Reliability Engineer (Platform Engineer) at Venntro, you will be helping to maintain, monitor, and evolve the mission critical systems that keep our internal and external applications running – across local, test and production environments.

Our award-winning platform is soon to turn 20, and presents a unique and exciting set of challenges.

Looking towards the future, we’re making inroads towards becoming a cloud-first platform, working with partners such as AWS and Cloudflare to solve problems in exciting new ways, and moving towards a containerised (Docker) and IaC defined (Terraform) estate. Meanwhile we continue to work on our traditional estate of dedicated and virtualised Linux devices running services at an enterprise scale – including Apache, MySQL, Nginx, Rabbit, Redis, and Sphinx, amongst others.

Our SREs / Platform Engineers are considered our infrastructure subject matter experts, and act as the bridge between development teams and our platform estate. You will be empowered to effect real change, and encouraged to bring new ideas and solutions to the table. You’ll use your knowledge to help guide developers on technologies or approaches to take for both new and existing projects, whilst working towards improving the overall architecture of the platform.

The ideal candidate for us will have a broad range of experience across a number of modern, typically open-source, web technologies, and is looking for the next step to advance their career. Most importantly, you will be deeply passionate about software engineering, and may even have come up with some creative technical solutions to problems outside of the workplace.

As part of our role of looking after local infrastructure, we also work to help the wider business with IT (Mac OS) support as required, as well as taking the lead on all matters concerning platform security.

  • Participate in the on-call rota and provide support during major incidents / emergencies.
  • Communicate incidents in a timely and clear way internally and externally as required.
  • Assist in IT support across the business as required.

  • Experience using Nginx to manage web servers.
  • Experience writing (My)SQL to query complex databases, and an understanding of MySQL replication principles.
  • Thorough knowledge of source control with Git and GitHub.
  • Configuration management or IaC experience (ideally Ansible or Terraform).
  • Understanding of both caching and event queueing concepts
  • Basic knowledge of networking protocols and concepts, including DNS.

Bonus Requirements:

Whilst not required, these skills are a bonus:

  • Development skills in any of JavaScript/PHP/Python/Ruby.
  • Previous exposure to the unique issues created at scale.
  • VMWare or virtualisation experience.
  • Docker or containerisation experience.
  • Previous usage of AWS.
