Job summary

Hidden Jobs is seeking a hands-on Staff Software Engineer on the Issuing server engineering team that owns the end-to-end card issuing platform powering multiple fintech brands, including one of the largest debit card programs in the United States.

The role focuses on the network boundary: specifications, protocols, certification, mandates, conformance, and production behavior across the full card lifecycle.

Qualifications

• Deep, current expertise with at least one major card network (Visa preferred), including ISO 8583, authorization and clearing flows, stand-in processing, specifications, certification, and mandate cycles.
• Personal experience building, certifying, or operating a live direct network connection rather than only integrating through a processor.
• Track record leading complex engineering work across multiple teams or systems.

Responsibilities

• Serve as a deep technical expert on global card networks, interpreting specifications, message flows, certification requirements, and mandates, and working directly with networks to influence outcomes.
• Lead complex, ambiguous engineering problems at the network boundary that span multiple teams and systems.
• Stay hands-on: write production code, build certification and conformance tooling, analyze network messages, review designs and code, and debug at the protocol level.
• Drive network certification and mandatory release cycles end to end and translate network requirements into clear engineering decisions.
• Establish shared frameworks, standards, tooling, and practices that make network expertise durable for other engineers.
• Share operational ownership of critical financial systems through on-call, incident response, and continuous reliability improvements.
