资深软件工程师，金融平台 - 发行
Staff Software Engineer, Financial Platform - Issuing
我们从2013年Block的一个想法开始。最初是为了简化点对点支付的痛苦，Cash App从一个单一功能的简单产品发展成了一个动态生态系统，开发独特的金融产品，包括Afterpay/Clearpay，为我们的5000多万月活跃客户提供更好的发送、消费、投资、借款和储蓄方式。我们希望重新定义世界与金钱的关系，使其更易于理解、即时可用且普遍可及。
如今，Cash App在全球各地的办公室和远程地点有数千名员工，我们的文化注重创新、协作和影响力。从第一天起，我们就是一支分布式团队，我们许多职位都可以在Cash App运营的国家远程完成。无论身处何地，我们都定制体验，确保员工富有创造力、高效且快乐。
##### **职位描述**
在Block，我们努力打造世界上最好的金融产品。金融平台发行团队负责卡发行平台，服务于每个Block品牌——支持Cash App卡，美国第四大借记卡计划，以及Square卡和Block即将推出的新的卡计划。
我们管理卡片的整个生命周期：发行、履行和激活；跨卡网络的实时交易授权和处理；数字钱包配置；3-D Secure认证；清算和结算；以及争议处理。当客户在收银台刷卡时，我们的系统会在毫秒级时间内决定结果，全天候运行，与卡网络和银行合作伙伴合作。
作为发行服务器工程团队的资深软件工程师，你将带来对卡网络的深入专业知识，参与我们路线图上最复杂的工程技术工作。你将与技术负责人和跨职能团队合作，深入研究我们的平台与网络的交汇点：规范、协议、认证、规定、符合性以及生产行为。
这是一个亲自动手的职位。你将构建系统和工具，进行消息级别的调试，并将你的网络专业知识转化为其他工程师可以使用的持久能力。你还将直接与网络本身合作——不仅理解它们的要求，还要知道在哪里以及如何影响Block的结果。

It all started with an idea at Block in 2013. Initially built to take the pain out of peer-to-peer payments, Cash App has gone from a simple product with a single purpose to a dynamic ecosystem, developing unique financial products, including Afterpay/Clearpay, to provide a better way to send, spend, invest, borrow and save to our 50+ million monthly active customers. We want to redefine the world’s relationship with money to make it more relatable, instantly available, and universally accessible.
Today, Cash App has thousands of employees working globally across office and remote locations, with a culture geared toward innovation, collaboration and impact. We’ve been a distributed team since day one, and many of our roles can be done remotely from the countries where Cash App operates. No matter the location, we tailor our experience to ensure our employees are creative, productive, and happy.
##### **The Role**
At Block, we strive to build the best financial products in the world. The Financial Platform Issuing team owns the card issuing platform that serves every Block brand — powering Cash App Card, the fourth-largest debit card program in the US, alongside Square Card and the new card programs Block launches next.
We run the full lifecycle of a card: issuance, fulfillment, and activation; real-time transaction authorization and processing across card networks; digital wallet provisioning; 3-D Secure authentication; clearing and settlement; and disputes. When a customer taps their card at a register, our systems decide the outcome in milliseconds, around the clock, in partnership with card networks and bank partners.
As a Staff Software Engineer on the Issuing server engineering team, you will bring deep card-network expertise to some of the most complex technical work on our roadmap. You will work alongside technical leads and cross functional teams, going deep where our platform meets the networks: specifications, protocols, certification, mandates, conformance, and production behavior.
This is a hands-on role. You will build systems and tooling, debug at the message level, and turn your network expertise into durable capabilities that other engineers can use. You will also work directly with the networks themselves — not only understanding what they require, but knowing where and how to influence outcomes for Block.
##### **You Will**
- 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.
##### **You Have**
- Deep, current expertise with at least one major card network, ideally Visa, including direct connectivity, ISO 8583, authorization and clearing flows, stand-in processing, specifications, certification, and mandate cycles.
- Personally built, certified, or operated a live direct network connection — not only integrated through a processor.
- Experience working directly with card networks to land concrete outcomes, such as rulings, exceptions, extensions, configuration changes, defect fixes, or certification outcomes.
- Strong hands-on software engineering experience building and operating highly reliable financial or payments systems at scale.
- A track record of leading technically complex, ambiguous work across team boundaries and influencing technical direction beyond your immediate area of ownership.
- Experience creating durable technical leverage — frameworks, standards, tooling, architecture, or practices that other engineers and teams adopt.
- Broad understanding of the card lifecycle, with depth in areas such as issuance and fulfillment, provisioning and activation, authorization, ledgering, clearing and settlement, reconciliation, disputes, or fraud.
- Working knowledge of Mastercard and American Express, alongside deep expertise in at least one major network.
- Fluency with AI-assisted engineering workflows and sound judgment in evaluating and applying AI-generated output.
- Willingness to participate in an on-call rotation for critical financial systems.
