Job Description

Senior Software Engineer (Full-Stack) - Defence & Security

We believe that AI should be transparent and responsible by design, and we’re looking for versatile people who can help us create it.

As a Senior Full-Stack Software Engineer, you will join the rapidly growing Engineering team at our University of Oxford machine learning company to help us realise a future where Humans and AI work together to solve the world’s most important problems.

Location: Remote (UK) or office-based (incl. mixed),

You’ll share your days with teams of talented software engineers, scientists, designers, and product specialists. Together, you will take ideas from concept through to production, making elegant and maintainable solutions to complex data-centric problems. You’ll help build an exciting portfolio of products that will have a real and positive impact on society, the defence of the realm, and the individual lives of people across the globe.

As a Senior Full-Stack Software Engineer, you will be at the heart of the engineering effort that enables the delivery of state-of-the-art AI/ML in a diverse range of projects; from signal processing to geospatial data modelling to image processing and high-fidelity simulations of physical systems.

You will work with users on new features, rapidly prototyping, exploring and validating ideas, and designing and developing features for scalable, secure, and observable large distributed systems, both on-premise and in the cloud.

We grow and succeed together by working in collaborative, flexible, and self-organising remote-first teams where your passion for software engineering and product development will allow you to thrive.

Working at Mind Foundry will provide an excellent platform for you to grow, learn, and impact the world's important problems by helping us realise our vision.

As part of this role, you will be required to work away at partner locations.Typically, this will be for up to one week at a time, but on occasion may be up to three weeks, and we aim for this not to happen more than once every two months.

You shall be willing and eligible to apply and obtain UK security clearance to Security Check (SC) if not hold an existing clearance.


We understand that no single person can do it all, and we don't expect everyone to be an expert in every aspect of frontend, backend & DevOps, but you’ll need to have skills & experience across many levels of a web app stack.

You will have at least five years of commercial software engineering experience and be an expert in at least one high-level programming language with familiarity with a range of others. We primarily use JavaScript/TypeScript and Python.

Our core technology stack is PostgreSQL, Kubernetes, and Python Machine Learning. We’d love for you to have experience in more than one of those and an understanding of Machine Learning, AI, or Data Science, including experience deploying ML in production or commercial applications. If you have equivalent experience in different technology stacks and have transferable skills, we’d still love to hear from you.

You have experience working in an iterative Agile environment and a good understanding of the DevOps movement, its tools and its culture. You will have been directly involved in helping to drive improvements to the way software is delivered in your previous roles.

You are motivated by mentoring and developing less experienced staff.

You have experience architecting and designing complex distributed software systems for the cloud and on-premise environments. You’ll understand different architectural patterns and the reasons for using them and be able to design secure and scalable systems.

You have a broad set of additional software engineering skills, for example, systems integration, scripting, CI/CD, UI/UX, design, and databases.

You have worked closely with users, working out what to build and why, and ideally, you will have had experience working closely with clients and representing technical expertise in discussions with other technical experts.

You keep on top of trends and new technologies and are a leader and mentor in your area of expertise. You are able to express your ideas clearly for audiences with differing levels of technical expertise. Perhaps you’ve written blogs or spoken at conferences.

We’d love it if you have experience in the following areas. If you’re already an expert, even better!

  • Familiarity with other technologies in our stack like protobuf/grpc, FastAPI, AWS
  • Experience with modern numeric or big data frameworks, such as Sklearn, Pandas, TensorFlow, PyTorch, Spark, Numba, Kafka, Apache Arrow, Parquet
  • Kubeflow or other MLOps technologies
  • We'll often need to integrate our software with external systems, so some experience integrating with software APIs and skills like networking configuration would be really useful to have.
  • User interface design and implementation, especially with React and Typescript

We would love to hear from you if this sounds like you and what you believe you can achieve.
