US Global Mobility Assistant Manager

London | Hybrid Working (3 Days Office / 2 Days Home) | Up to £61,000 + Benefits

Looking to take the next step in your US Global Mobility career with a team that is genuinely investing in growth?

An exciting opportunity has arisen for a US Global Mobility Assistant Manager to join a highly regarded international tax practice with ambitious expansion plans. This is a fantastic chance to join a growing team where you'll gain significant client exposure, a strong mix of advisory and compliance work, and clear opportunities for progression.

Working with a diverse portfolio of clients, you will advise internationally mobile employees and businesses on a range of complex US tax matters, including international assignments, Social Security, treaty positions, equity compensation and cross-border tax planning.

Unlike many larger firms, this role offers genuine variety and ownership, allowing you to build strong client relationships and develop your technical and commercial skills in equal measure.

The Role

• Review and prepare complex US individual tax returns
• Manage client relationships and engagements from start to finish
• Advise on US inbound and outbound assignments
• Deliver entry and exit consultations for globally mobile employees
• Provide guidance on US federal and state tax matters
• Advise on Social Security, equity compensation and treaty positions
• Work closely with UK tax specialists to deliver joined-up cross-border advice
• Support a broad range of planning and advisory projects

About You

Ideally, you will have:

• US tax experience within a Global Mobility environment
• Experience reviewing US individual tax returns
• Strong client-facing and relationship management skills
• The ability to manage multiple assignments simultaneously
• Excellent communication and organisational skills

Experience within US expatriate tax, international assignments or cross-border private client work will be highly advantageous.

Enrolled Agent (EA) qualification is desirable but not essential, and support will be provided for further professional development.

Why Apply?

• Growing team with significant investment and expansion plans
• Approximately 50% advisory and 50% compliance work
• High levels of client exposure and responsibility
• Broad and varied international client base
• Merit-based progression rather than waiting for annual promotion cycles
• Support towards professional qualifications
• Hybrid working arrangement
• Salary up to £62,000 DOE plus a strong benefits package

If you're looking for a role that offers more variety, more advisory exposure and genuine opportunities for advancement, we'd be delighted to tell you more.
