About Arondite

Arondite is a defence technology company building the foundational software and AI to power the autonomous age. Our aim is to revolutionise the way organisations collaborate with sensors, robots and autonomous systems and use the data they generate. We are driven by our determination to help defend our collective democratic values and by our strong belief that an elite group of engineers can make a big difference. We are ambitious, well-funded and building for the long-term.

You will join Arondite at a pivotal moment in the company’s journey.Our company is being built by exceptional engineers - people who find high-impact and technically 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. From your first day, you will directly influence the design, functionality, and direction of Arondite’s product offering. 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 a growing team of outstanding people, then we want to hear from you.

Requirements

Arondite is looking for an experienced software engineer with at least 5+ years' experience building and deploying product. You will drive the development of software to enable robots and autonomous systems to collaborate, process large sensor datasets, and build graphical user interfaces for the web and Android. User interfaces will involve the presentation of complex information in an intuitive way to enable tasking and control of multiple assets.

You will be expected to write flexible and maintainable code that will operate in mission-critical environments. The role will also involve interfacing with third-party APIs and the development of our own. You will iterate closely with end users to rapidly improve our products based on their feedback and priorities.

As an early member of the engineering team, you can expect to have a big influence on how we do things; you will help with hiring as we continue to expand, and influence the development of our engineering-driven culture.

You should apply if you have:

  • Strong core programming skills in a server-side language such as C++, Java, Rust or Python
  • 5+ years professional experience
  • Front-end development experience in TypeScript or JavaScript, using frameworks such as Angular or React
  • A degree in Computer Science, Engineering, or a related technical/scientific subject (or equivalent experience)
  • A deep enthusiasm for expanding your knowledge of a diverse technology stack

Ideally, you would also have:

  • Understanding of embedded / resource constrained devices
  • Experience with Docker and Kubernetes
  • Experience with SQL databases such as PostgreSQL
  • Experience of machine learning applications
  • Experience with media streaming applications
  • Experience in defence or defence technology

Note: We want Arondite to bring together individuals from diverse backgrounds and perspectives. We don't expect everyone to have experience across each of these areas. Please apply even if you only partially fulfil this list.

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

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:

  1. CV submission with initial questions
  2. Introductory Teams call (30 mins)
  3. In-person technical interview (1-2 hours)
  4. 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
  • A great office in Old Street offering wellness workshops and community events
  • Free breakfast and lunch every day; free pizza and beers weekly
  • Private health and dental insurance
  • Cycle to work scheme
  • Relocation support
  • Visa sponsorship for extremely strong candidates
  • Access to any resources, equipment and training that you need to do your job in a world-class way
  • The opportunity to work with and learn from exceptional colleagues with excellent academic experience and deep industry knowledge
