Job description

At EY, we’re more than just accountants and consultants — we’re change-makers. With over 300,000 people globally, we use our expertise in tax, transactions, assurance, and advisory services to build a better working world. Whether you are helping companies expand overseas or advising on the future of work, everything we do is about making progress — for our clients, our communities, and our people.

We believe in giving you the tools and freedom to shape your future, with top-tier training, real opportunities, and a team that’s got your back.

Why EY Is Different

At EY, you’re in the driver’s seat. Whether you’re passionate about solving complex problems, working with global brands, or building strong relationships with clients, we give you the platform to explore, grow, and thrive.

You’ll join a powerful network of 300,000+ professionals and one million alumni, all working to create impact every day. Our culture is inclusive, entrepreneurial, and supportive — where your ideas are heard, and your individuality is celebrated.

What You’ll Do

We’re looking for a Senior Consultant to join our Assignment Services team. This is a client-facing role where you’ll play a key part in helping multinational companies manage their globally mobile employees — from tax and payroll to relocation and policy support.

You’ll work with some of the biggest brands in the world, helping them run smooth international assignments while gaining hands-on experience in consulting, project management, and global mobility.

Your Day-to-Day Could Include:

• Being the go-to advisor for international assignees and global mobility teams
• Handling queries, running video briefings, and offering real-time support
• Reviewing assignment documentation like compensation packages and cost estimates
• Collaborating with teams across borders (including our offshore hubs)
• Keeping projects on track and ensuring we hit our service goals
• Helping develop solutions that make global moves easier for companies and their people
• Getting involved in proposal work and new business opportunities
• Continuously looking for ways to improve how we work

What We’re Looking For

You don’t need to have a decade of experience — what matters most is your mindset. If you’re naturally curious, confident with numbers, love solving problems, and care about making things better for clients and teammates, you’ll thrive here.

• Ability to analyse and interpret data and articulate these findings succinctly
• Strong communicator (written and verbal)
• Great with people – confident in building relationships
• Comfortable juggling multiple tasks and priorities
• Sharp attention to detail
• Analytical thinker who enjoys making things run better
• Confident with Excel and Word (PowerPoint is a plus!)
• Curious about global business, tax, HR, and international mobility
• Team player who’s also happy to take initiative
• Experience in assignment management, HR, tax, or global mobility is great, but not essential — we’ll support your development every step of the way.

Rewards

At EY, we don’t believe in one-size-fits-all careers. Here’s what you can expect:

• Real autonomy to shape your role and career path
• Work with global clients and collaborate across borders
• Coaching and support from experienced professionals
• Learning and development tailored to your goals
• Flexibility – including hybrid and remote working options
• A chance to travel (depending on the role and client needs)
• A competitive reward package with personalized benefits
• A culture where you belong, no matter your background

Belonging at EY

We’re proud to be one of the most people-focused organizations in professional services. Belonging isn’t just a buzzword for us — it’s about creating a space where everyone can show up as their true selves, be heard, and thrive.
