The client is an unnamed but “well-known bank”.

The consultancy specialises in large-scale, critical IT systems and works with blue-chip organisations on “digital transformation” programmes.

The firm is headquartered in Leeds and has offices in London and Manchester with an increasing workforce of over 400.

Infinity Works expects revenues to exceed £30 million this year.

Its recent projects in financial services include the design and delivery of cloud infrastructure for open banking, reporting regulatory compliance and mobile banking applications.

The company has leased offices at WeWork in George Street to base its growing team of software engineers, technical architects and technical leads.

Paul Henshaw, co-founder and director, told The Scotsman: “George Street is a showcase location and will help us to continue to attract great talent in a competitive market.“While we are no longer technically a start-up, we still try to reflect the start-up culture and mentality and our new set-up keeps that way of working and thinking close to our heart.

“It also allows us to host and sponsor fun meet-ups for the tech community to get together and share knowledge about the latest technologies.

“Ultimately it underlines we are a serious grown-up business in Edinburgh now and it is a brilliant opportunity to build a fantastic new Infinity Works operation in a great city.”
