Tide

Tide operates a mobile-first financial platform built for small and medium businesses, handling business banking, invoicing, accounting, payments, and savings through a single OS. Founded in 2015, the company has scaled to over 1.5 million members and is recognized as one of the UK's fastest-growing fintechs. Its geographic footprint spans the UK, India, Germany, France, and Luxembourg, with engineering hubs in London, Sofia, Hyderabad, Berlin, and Delhi.

For a cybersecurity team, the threat model is concrete: you're protecting the financial data and transaction integrity of over a million SMEs whose owners are often non-technical. That means real-time fraud detection, secure mobile authentication, PCI-DSS compliance, API security across banking integrations, and defense against account takeover attacks targeting users who may not spot phishing. The attack surface is wide - mobile apps, cloud infrastructure, third-party financial integrations, and the interconnection between banking, invoicing, and payment modules all create lateral movement opportunities.

Tide's platform consolidates what would otherwise be separate tools - bank accounts, invoicing, accounting, and savings - into a single financial operating system. This architectural choice means security engineers deal with deeply integrated systems where a vulnerability in one domain can cascade across others. The company's scale (1.5M+ members) and growth trajectory amplify the stakes: you're building security controls for a platform that processes real business-critical financial transactions across multiple jurisdictions with varying regulatory requirements.
