Arondite is the British defence tech company for an autonomous age. We build technology that delivers immediate, real-world impact on a global scale.
Backed by Index Ventures

About Arondite

Arondite enables organisations to wield autonomy, data and AI at scale. We equip operators with the foundational software to orchestrate their mix of platforms and capabilities, and then take mission-critical decisions faster than their adversaries.

We exist to ensure the UK and its allies out-think, out-pace and out-adapt those who seek to threaten our values and way of life. Our technology is designed for deployment in the world’s most austere environments, and is relied upon by the world’s most demanding operators. We deploy alongside them, bringing our technical expertise wherever it is needed.

You will join Arondite at a pivotal moment in the company’s journey. We are ambitious, building for the long-term and backed by globally renowned investors including Index Ventures (Anthropic, Wiz, Figma, Revolut). Our company is being built by exceptional people; people who find high-tempo and challenging work engaging and exciting, and who consistently deliver outsized impact. You will collaborate with other brilliant minds to solve some of the world’s hardest and most important problems.

You will have ownership and autonomy from Day One. There is no corporate ladder at Arondite. We hire the best people and give them extremely high levels of autonomy; the sky is the limit for an individual with the right ambition.

If you are motivated by our mission and if you want to be part of an outstanding team, then we want to hear from you.

About the role

We're looking for a skilled Technical Operations & IT Specialist to ensure the stability, performance, and security of our technology infrastructure, with a particular focus on supporting our engineering team. The ideal candidate will not only maintain existing development and IT systems but also improve and optimise our cybersecurity and network infrastructure. This role bridges the gap between operations and engineering, helping to streamline workflows, automate processes, and create a robust technical environment that enables productivity across the whole company.

Your responsibilities will include:

  • Implementing and supporting a diverse corporate IT environment that spans Windows, Linux and Apple devices
  • Interacting closely with the engineering team to deliver a reliable and low-friction development environment
  • Deploying and maintaining scalable, secure network infrastructure
  • Following cybersecurity policies, procedures, and standards aligned with industry best practices
  • Helping meet UK government accreditations for IT systems and networks
  • Maintaining accurate documentation of system configurations, common procedures, and troubleshooting steps to help users across the business to solve their own problems
  • Automating repetitive tasks and processes to improve business efficiency
  • Taking ownership of the day-to-day running of IT and keeping the whole function well managed
  • Participating in on-call rotation for critical system issues as needed

Requirements

Arondite aims to bring together individuals from diverse backgrounds and with different perspectives. We therefore don’t expect people to have experience across every area of the requirements. Please apply even if you only partially fulfil the following lists.

You should have:

  • 2 years of experience in IT operations, including supporting multidisciplinary development teams
  • Good knowledge of Microsoft 365 and its administrative tools
  • Practical experience using major Identity Providers and configuring SSO, SAML and related technologies
  • Experience with the major cloud computing providers such as AWS, Azure, and/or GCP
  • Experience designing and implementing secure network infrastructure using devices such as next generation firewalls and VPNs
  • Strong proficiency in managing and supporting Windows, Apple and/or Linux systems in a corporate environment
  • Sound understanding of software development lifecycles and modern development practices
  • Excellent communication skills, with the ability to collaborate effectively with technical teams

Ideally, you would also have:

This is not an additional list of requirements; this reflects the tech stack currently used at Arondite; any experience in these areas is a bonus

  • Security certifications (CISSP, CEH, Security+)
  • Network certifications (CCNA, Network+)
  • Familiarity with key industry standards such ISO 27001 and CyberEssentials, Defence Cyber Certification
  • Experience with Zero Trust Network Access and related technologies
  • Experience with disaster recovery and business continuity planning

Right to Work

We require that all candidates have an existing Right to Work in the UK at the time of application.

Security clearance

We believe in working closely with defence customers. As a result, this role will require the individual to hold a clearance or be willing to undergo UK security vetting to Security Check (SC) or above. This normally requires having continuous residency in the UK for at least 5 years.

Office vs Hybrid working

We are focused on building a positive, collaborative engineering-driven culture. We therefore believe in making the office a friendly, comfortable and fun place to be, and we try to work from the office where possible. Of course, there are times when it makes sense for you to work from home and that's OK. You may also need to travel to visit customers, depending on your role. But in general you should only apply to join Arondite if you're excited to come into the office and work in person by default.

Application process

Generally, our interview process is comprised of the following stages:

  • CV submission with initial questions
  • Introductory Teams call (30-45 mins)
  • In-person technical interview (1-2 hours)
  • Final interview with one of Arondite’s Founders (30 mins)

Benefits

  • Highly competitive base salary
  • Generous equity in EMI share options in a well-funded and growing startup
  • 7% employer pension contribution
  • Free meals in the office every day
  • Private health and dental insurance, with opt-in cover for dependents
  • Cycle to work scheme
  • Relocation support
  • Access to any resources, equipment and training that you need to do your job in a world-class way
