Railpen Tech Stack

Pension administration and investment platform serving 350K+ members

Financial Services City of London, London 501–1,000 employees Privately Held

Railpen administers over £34bn in pension assets for more than 350,000 members across defined benefit, defined contribution, and hybrid schemes. The tech stack is firmly Microsoft-centric (Azure, SQL Server, Power BI, .NET), with active infrastructure uplift and security enhancement projects underway. Hiring is operations-heavy (12 ops roles out of 39 open positions) and accelerating, suggesting concurrent pressure on benefit payment accuracy and finance application support — two explicit pain points — while the company scales regulatory and technology workstreams.
