About us
MI5 keeps the country safe from serious threats like terrorism and from attempts by states to
harm the UK, its people and way of life. We carry out investigations by obtaining, analysing
and assessing intelligence, and then work with a range of partners, including MI6 and
GCHQ, to disrupt these threats. Through our protective security arm, we provide advice and
guidance to government, businesses and other organisations on how to keep themselves
safe. A role in MI5 means you’ll do unique and challenging work in a supportive and
encouraging environment, making a real difference to UK national security.
The role
As a Lead Researcher, you’ll bring your specialist STEM knowledge and experience in
conducting Scientific research that is both rigorous and ethical to MI5 and MI6, helping to
address mission-critical priorities. You’ll join a joint MI5–MI6 science team made up of
researchers, scientists, leaders, and strategists. Working together, you’ll explore
opportunities created by scientific and technical advancements and share your findings to
benefit the wider intelligence community.
Managing the end-to-end delivery of scientific research projects will be a key part of your
role. The work is highly varied; you’ll be shaping ideas and securing agreement from
stakeholders, carrying out detailed analysis of your findings, and ensuring your research
delivers value for money. Through a mix of individual and cross-team projects, your ideas
will help unlock innovative scientific solutions that meet unique customer and stakeholder
needs. This includes advancing our understanding of AI, machine learning, and data
science, and developing solutions that strengthen our capabilities in these areas.
Communication is central to the role. You’ll share research with a broad range of technical
and non-technical audiences, collaborate with other researchers, and help build an inclusive
scientific community. You might deliver a research briefing to senior leaders, take part in a
poster session to explain your latest scientific advancements to colleagues across the
community, as well as oversee the work of junior researchers. A significant portion of your
time will involve working with your immediate team, the wider organisation, customers,
stakeholders and industry partners to understand their needs.
Please note, formal line management responsibilities aren’t expected in your first year, but
we welcome candidates interested in developing into leadership roles in the future.

Working closely with colleagues and teams across our organisation requires excellent
collaboration and interpersonal skills. Equally important is the ability to explain complex
concepts clearly to those unfamiliar with scientific details, whether through group

community events and shadow other teams.

on-the-job and formal training you may require to continue growing your skills.
