Job Description

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. You will take ideas from concept to production together, making elegant and maintainable solutions to complex data-centric problems. What you build 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 diverse 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 in the UK. Typically, this will be for up to three weeks at a time, 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), or 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 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 Python and JavaScript/TypeScript.

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 as a technical lead working in an iterative Agile environment, and you have a good understanding of the DevOps movement, its tools and its culture. You will have been directly involved in helping to drive improvements to how software is delivered in your previous roles and 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, such as systems integration, scripting, CI/CD, UI/UX, design, and databases.

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

You keep on top of trends and new technologies and are a leader and mentor in your area of expertise. You can express your ideas clearly for audiences with differing levels of technical knowledge. 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, Flask, Redux, 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 beneficial.
  • User interface design and implementation, especially with React and Node.js

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