Primer.io builds a unified payment infrastructure platform - a single orchestration layer that lets merchants connect any payment provider, route transactions intelligently, and expand into new markets without rebuilding their stack from scratch each time. The core threat surface here is financial: transaction data in motion, provider credentials at rest, and the integrity of routing logic that decides where sensitive payment details flow.
The Primer platform handles payment integration across the full provider ecosystem - acquirers, gateways, fraud tools, and alternative payment methods - abstracting away the technical complexity so engineering teams in retail, travel, and fintech can swap or add providers without code-level rewrites. That abstraction layer is where security engineering matters most: authentication flows, tokenization boundaries, webhook verification, and the APIs that let merchants configure routing rules without exposing themselves to misconfiguration risk.
Operating at the intersection of payment processing and financial technology, the team works on infrastructure that must meet PCI-DSS obligations by design. The engineering challenge is building orchestration that's both flexible enough to handle global payment diversity and hardened enough to stand up to the regulatory and adversarial realities of moving money at scale.
