Software Engineer in City of London

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.

You will be driving the development of software to enable autonomous systems to collaborate, process large sensor datasets, and build graphical user interfaces that involve the presentation of complex information in an intuitive way to enable tasking and control of multiple assets. You will be expected to write high quality code that will drive the planning and execution of operations in mission‑critical environments. You will iterate closely with end users to rapidly add and improve the most relevant features to support their priorities – this may sometimes involve working outdoors and at other sites.

Your responsibilities will include:

• Designing, building, and testing the core software platforms and user interfaces at Arondite
• Iterating with customers and users to better understand and implement their requirements
• Interfacing with and testing autonomous and robotic systems in the field
• Collaborating with engineers with diverse skill sets, including AI/ML, networking, and robotics
• Driving a culture of excellence within the engineering team and the wider company

Experience Required:

We are open to candidates of all levels of experience, from senior engineers looking to lead a team or be a high‑value IC, to new‑grads looking to start their career with a bang. We are looking for candidates with experience across the development stack, from frontend UX experts who delight in producing a polished and beautiful experience, to networking maestros who understand and optimise the complex topology required to support our platform (and everything in‑between).

Requirements

You should have:

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

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

• Understanding of working on embedded / resource constrained devices
• Experience with Docker and Kubernetes
• Experience with SQL databases such as PostgreSQL
• Experience of machine learning applications
• Experience with frontend mapping frameworks (e.g., Cesium, Mapbox, Leaflet)
• Knowledge of application security best practices and secure coding principles (e.g., OWASP Top 10)

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.

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 mins)
• In‑person technical interview (1‑2 hours)
• Final interview with one of Arondite’s Founders (30 mins)
