The Opportunity

My client, a well-established financial services advisory firm, needs a Finance Systems Specialist to join their Application Support function. This is a brilliant role for someone with strong Sage Intacct and Concur experience who wants to take ownership of finance systems in a growing business.

You'll be the go-to person for all finance system issues, working closely with Finance teams and IT to keep their Microsoft/Azure environment running smoothly. Great opportunity to get involved in projects and really make an impact.

What You'll Be Doing

Day-to-Day

Troubleshoot and fix issues with Sage Intacct, Concur, and other finance systems
Handle user access requests and system configurations
Run daily checks on data integrity and system processes
Support month-end/year-end activities when systems need to be rock solid
Work with Finance teams to understand what they need from the systems

Projects & Development

The Technical Bit

Manage system configurations, user permissions, and security settings
Monitor performance and fix bottlenecks
Work with the Software Engineering team on integrations
Support audits by providing system evidence and documentation

What You Need

Must Haves:

Hands-on technical experience with Sage Intacct and Concur (not just using them, but configuring/administering)
Solid understanding of finance processes - GL, AP/AR, expense management, financial reporting
Experience leading system implementations or major upgrades
Strong Excel skills and ideally some PowerBI experience
Project management experience - you'll be juggling multiple things
Good communication skills - you'll be dealing with Finance teams who aren't technical

Nice to Haves:

Professional Services background
Experience with integration platforms like Workato
Some SQL knowledge for reporting
ITSM/ITIL framework knowledge

What's in it for You?

Excellent benefits package (pension, healthcare, life insurance)
5 days in office, during 3 month probation period. Hybrid working thereafter
25 days holiday + bank holidays
Training budget and career development opportunities
Modern offices in Central London
Friendly team environment - they actually talk to each other!

Ready to take the next step in your finance systems career?

We'd love to hear from you if you're passionate about finance technology and eager to drive operational excellence within a dynamic financial services environment.
