Senior Machine Learning Engineer - National Security (London)

We’re looking for a Senior Machine Learning Engineer to join a supportive, multidisciplinary team developing AI/ML systems to solve critical National Security challenges. As a Senior Machine Learning Engineer, you’ll lead onsite engagements with clients and stakeholders to translate their problems into robust, production-ready machine learning solutions. You’ll rapidly explore, prototype, and deploy ML approaches both within and beyond our core capability offerings, taking ownership from initial concept through to live operation. Working at the forefront of applied AI alongside experts across multiple disciplines, you’ll help users defend against Defence and National Security threats, directly contributing to safer, more resilient systems deployed where they matter most.

Mind Foundry works on some of the most complex and urgent challenges in Defence and National Security. We specialise in supporting customers across the community to make sense at the speed of relevance from the ever-increasing volumes of data collected by sensors and systems. We often find ourselves working at the edge in complex environments where power, compute, and bandwidth are in short supply. The work is challenging, the customer needs products and applications they can trust, and the sense of achievement is therefore substantial.

This is an opportunity to innovate at the forefront of applied machine learning, tackle high-impact real-world problems, grow your technical skills, and shape the way AI/ML solutions are delivered to critical operational environments.

Because of the nature of this work:

• You will need to hold existing or be eligible for UK Developed Vetting (DV), details of which can be found on the Gov UK website.
• Be expected to work primarily onsite at our clients’ sites in London. Please consider your commute when applying.
  
  

Key day-to-day activities:

• Lead technical scoping and make key architectural decisions to enable delivery of professional-level ML solutions.

Experience with Natural Language Processing (NLP), Large Language Models (LLMs) or Image Processing.

Experience in areas of model development, data processing and streaming (Spark, Kafka), microservices in python (Flask or FastAPI), and interactive visualisations and User Interfaces (Streamlit, Plotly, Gradio etc).

While we think the above experience is important, we’re keen to hear from people that believe they have valuable skills, ideas, or perspectives that will make an impact in this role. If our team and mission resonate with you, but you do not necessarily meet all our requirements, we still encourage you to apply.

What do we offer?

We believe in investing in our people by encouraging career and personal development that aligns with your goals and ambitions. We make sure all staff have the tools, time and support they need to shape their own professional development. We want to help you excel at what you do and support your growth within the company.

You’ll enjoy a competitive compensation package and great benefits such as:

• 25 days of annual leave plus Bank Holidays
• Salary Sacrifice Pension scheme with a 5% employer contribution (minimum 5% employee contribution)
• Private Healthcare (including dental and optical cover)
• Group Life Cover at x3 your annual salary once you pass your probation period
• Enhanced Paid Parental and Sickness Leave
• Workplace Nursery Scheme
• Pet friendly office
• Professional and personal development
