Staff Software Engineer - Card Issuing Platform (Remote)

Precision Labs; California; Hybrid; USD 264,000 - 395,000; Full time

Job summary

Block is seeking a Staff Software Engineer for the Financial Platform Issuing team. You will own network-specific engineering at the card-network boundary, interacting directly with networks to define and land concrete outcomes.

You will write production code, build conformance tooling, and influence certification timelines while guiding other engineers. This hands-on role emphasizes reliability, scalability, and strategic collaboration with partner networks.

Qualifications

• Deep, current expertise with at least one major card network.
• Built or operated a live direct network connection.
• Experience landing concrete outcomes with card networks.
• Hands-on software engineering for reliable payments systems.
• Led technically complex work across teams.
• Created durable technical leverage through tooling or standards.
• Broad understanding of card lifecycle: issuance, fulfillment, authorization, settlement.
• Knowledge of Mastercard/AmEx with deep expertise in one network.
• Fluency with AI-assisted engineering workflows.
• Willingness to participate in on-call rotation.

Responsibilities

• Be a deep technical expert on global card networks, helping Issuing teams interpret network specifications, message flows, certification requirements, mandates, and production behavior — and working directly with the networks to influence requirements, resolve ambiguity, and secure outcomes that matter for Block.
• Lead complex, ambiguous engineering problems at the network boundary that span multiple teams, systems, or domains.
• Partner with technical leads, program DRIs, and senior stakeholders to shape solutions where card-network requirements intersect with Block's issuing platform.
• Stay deeply hands-on: write production code, build certification and conformance tooling, analyze network messages, review designs and code, and debug issues down to the protocol and field level.
• Drive network certification and mandatory release cycles end to end, and translate network requirements into clear, pragmatic engineering decisions.
• Establish shared frameworks, standards, tooling, and practices that make network expertise durable and enable teams to operate independently.
• Raise the technical capability of engineers around you through design guidance, code reviews, mentorship, documentation, and clear technical judgment.
• Apply AI-powered tools throughout the engineering lifecycle to improve velocity and quality, and help establish effective patterns for broader team use.
• Share operational ownership of critical financial systems through on-call, incident response, and continuous improvements to reliability and correctness.
