US & UK Accountant — Delaware C-Corp with UK Subsidiary

We're an early-stage B2B software company with a Delaware C-Corp parent and a UK subsidiary. We're looking for an accountant experienced in both jurisdictions to help us get our filings and finance function in order.

Immediate priority — due 15 October
Form 1120 and Form 5471 for FY2025. We also need to confirm whether Form 5472 and FBAR apply to us. An extension was filed in April, so this is the hard deadline.

What we're looking for

Demonstrable experience with US-parent, foreign-subsidiary structures — 5471 and 5472 specifically
CPA or equivalent
Available to start immediately given the October deadline
