The British Government’s Embassy in Washington is offering an exciting opportunity to join the British Defence Staff – United States (BDSUS) as the Senior Defence Congressional Advisor. This is a meaningful role which supports and further develops the special relationship between the UK and the US—contributing to work shaping international diplomacy and advancing UK defence and security priorities at the heart of Washington policymaking.

The US Network offers a unique, career enhancing opportunity and is committed to supporting its staff through a comprehensive benefits package, including generous leave, competitive insurance options, a top tier 401(k) programme, and access to world class learning and development resources.

We are committed to fostering a healthy work life balance and supporting employee wellbeing through a structured hybrid working model that includes opportunities for remote work and flexible hours, where operational needs allow.

In this role, you will be part of a dynamic international environment spanning the British Government’s extensive network across the United States and the United Kingdom, which includes the Embassy in Washington, the UK Mission to the United Nations, multiple Consulates, and other Government Offices—comprising over 900 staff and supporting the work of approximately 30 UK government departments and agencies.

As Senior Defence Congressional Advisor for the British Defence Staff – United States, you will play a central role in strengthening UK US collaboration on the breadth of the UK-US defence relationship. Positioned within the Political Section, the role will work closely with the Political Counsellor, while reporting to the Defence Counsellor for Policy and Strategy in the British Defence Staff. You will support internal stakeholders such as defence policy teams (based in D.C and the UK) and the Embassy’s Senior Leadership Team to design and deliver effective strategies for congressional engagement and work closely with external partners including Congressional offices. This role supports the UK’s broader strategic objectives across the Defence relationship and offers valuable experience in international engagement and cross-government collaboration. You will also oversee the team’s Congressional Adviser and support the development of UK colleagues’ understanding of Congressional dynamics.

We’re looking for a strategic, credible, and proactive professional with significant experience of working on the Hill on a range of defence policy issues. You will bring strong communication, stakeholder engagement, and strategic judgement skills, alongside a sophisticated understanding of the U.S. political and national security landscape. A commitment to high quality advice, effective leadership, and continuous learning will be essential to success in this role.

Roles and responsibilities:

The Senior Defence Congressional Advisor leads the British Defence Staff’s engagement with the U.S. Congress, ensuring UK defence equities are effectively advanced and protected.

Congressional Engagement and Advocacy (about 30%)

Linked to the strategies developed above, you will lead extensive engagement with key Congressional contacts to advocate for UK interests, with particular focus on the National Defence Authorization Act (NDAA) and defence appropriations processes. This includes maintaining a firmly non‑partisan profile; advancing UK objectives with Members of Congress and staff; identifying opportunities and risks; and spotting emerging trends, key personalities, and rising influencers relevant to UK defence policy. This will include ensuring effective stakeholder mapping of key contacts.

Analysis and Reporting (about 15%)

You will proactively track Congressional activity across the full range of U.S. defence policy issues, providing early warning, contextualised analysis, and politically astute advice to Embassy leadership and subject‑matter experts in Washington and London. Deliverables include a suite of regular written reports on events, trends, and Congressional dynamics, alongside rapid, high‑quality reactive reporting on emerging issues.

Briefing, Visits, and Senior Engagement Support (about 15%)

You will produce high‑quality written briefing and talking points for senior official and ministerial engagements with Congress. You will also identify and develop opportunities for inward and outward visits between Washington and London, supporting programmes and engagement strategies that strengthen UK‑US defence relationships and advance policy aims.
