United Kingdom PQShield Full time

Location: Remote (within the UK) London/Oxford. Some travel to our offices will be required from time-to-time

Department: Operations

About the role

PQShield is looking for a IT & Infrastructure Engineer to expand our Engineering team. 

We have been established since 2018, so you would be directly working with the founders and inventors of this deep tech startup. The technology is already a couple of years in the making, its feasibility having been established, funding secured, and it has a clear path to market. This is a great opportunity for career progression and to get a head start in a rapidly expanding segment of the semiconductor industry (Post-Quantum Cryptography and RISC-V).

Our platform IP components come together as a RISC-V MCU based Sub-system with advanced (post-quantum) cryptography algorithm support and security features.

We are looking for an IT & Infrastructure Engineer to help manage our server infrastructure, network security and general IT – helping us take PQShield to the next level as we expand internationally. You will report to the Infrastructure Manager.

We are a fast growing but small team of around 65 people, which means this role will be very hands-on, but at the same time you’ll be helping to develop the long-term strategy of the team and business.

Our server infrastructure, policies and documentation are developed and mature, but we have plenty more big projects to take on, such as rolling out an MDM for end-user devices. In addition, our infrastructure environment is always expanding.

️ What you’ll be doing

  • Developing and supporting the management of our existing development servers – these are physical machines running Linux (CentOS, Rocky Linux, Xen Enterprise and Ubuntu) and Mac OS.
  • Managing our network infrastructure and IT security across the company.
  • Managing our colleagues’ laptops and desktops across all three platforms - Windows, MacOS and Ubuntu – including endpoint security.
  • Managing our IT cloud services (such as Google Workspace and Atlassian), and provisioning accounts for new users, as well as taking care of IT offboarding tasks.
  • Procuring and implementing new tooling (such as an MDM), to further automate IT management and improve security.
  • Working with the Infrastructure Manager to maintain and develop comprehensive documentation of the environment.
  • Working with our suppliers to procure new equipment (such as servers and switches) when required.
  • Helping our team with IT support queries when they come up.
  • Helping to maintain our certifications, including Cyber Essentials and the IT focussed parts of ISO 27001.

Required Skills And Qualifications

  • You have strong experience with Linux administration and are keen to continue developing your talents.
  • You have experience in IT support for both Windows and MacOS, and are keen to continue and build on this.
  • You are organised and like to document your work and the systems that you build (we use Jira and Confluence).
  • You like working with people, are empathetic to colleagues’ problems, and can help tailor policies and processes in this regard.
  • You like to be hands-on – you’re comfortable scripting, configuring, and installing things.
  • You have experience working with networks and troubleshooting network problems, as well as network security – including configuration of firewalls and appropriate security policies.
  • You like getting stuff done, building and improving things, and have a ‘no job too small’ attitude.

Nice to have:

  • Red Hat Certified.
  • Experience with Jira and Confluence.
  • Experience rolling out and/or managing an MDM (such as JumpCloud).
  • Experience working with Ansible and Git.

Some of the perks of working with us:

  • Unparalleled opportunities to learn and accelerated career development.
  • A collaborative, team environment with people who truly love what they do.
  • Competitive salary and share option scheme.
  • Flexible and hybrid working, and a working from home budget.
  • Private health insurance for yourself and your family.
  • 25 days annual leave (plus bank holidays and two wellness weeks).
  • The chance to work with a spirited, smart, and friendly team


PQShield is an Equal Employment Opportunity employer. We’re passionate about talent and proud to foster an inclusive environment; all applicants will be considered regardless of their gender identity, ethnicity, sexual orientation, disability, and age.
