Common questions
FAQs from hiring managers
Can you work outside IR35?
Yes. iCore Fusion Ltd is a UK limited company and Adam operates as a genuine B2B contractor. For roles assessed as outside IR35, engagements are structured directly with iCore Fusion Ltd. For roles inside IR35, umbrella arrangements can be discussed.
Can you work Corp-to-Corp for US engagements?
Yes. iCore Fusion LLC is a Wyoming-registered US entity. US clients can engage directly Corp-to-Corp without needing an agency or employer of record. Standard W-9 and vendor documentation provided on request.
What is your notice period or availability?
Immediate start available as of June 2026. For ongoing contracts, standard notice period is two weeks unless otherwise agreed in the statement of work.
Do you work with agencies or only direct?
Both — but direct is preferred and always cheaper for you. iCore Fusion works directly with clients wherever possible. If your procurement process requires an agency, Adam can be engaged through a preferred supplier.
What platforms have you worked on most recently?
Elastic Security at BT (Jan–Mar 2026) and Microsoft Sentinel at Charles River Associates (May 2024–Dec 2025). Both at senior engineering level. QRadar and Splunk from earlier enterprise roles at IBM and Ford Motor Company.
Can a contract lead to a permanent hire?
Yes — and we actively support this. iCore Fusion offers a formal contract-to-hire pathway. After a minimum 6-month engagement, if both parties want to transition to a permanent arrangement, iCore Fusion supports the handover. A conversion fee applies.
What languages do you work in?
English and French — both fluent. Adam has delivered engagements across the UK, Switzerland, and USA and is comfortable working in international team environments.
Ready to start the conversation?
No agency. No forms. No waiting room. Send a direct message and Adam responds personally — usually within a few hours.
