Block is one company built from many blocks, all united by the same purpose of economic empowerment. The blocks that form our foundational teams — People, Finance, Counsel, Hardware, Information Security, Platform Infrastructure Engineering, and more — provide support and guidance at the corporate level. They work across business groups and around the globe, spanning time zones and disciplines to develop inclusive People policies, forecast finances, give legal counsel, safeguard systems, nurture new initiatives, and more. Every challenge creates possibilities, and we need different perspectives to see them all. Bring yours to Block. The Role The People Technology team, part of the People Automation and Operations organization, manages the infrastructure powering Block's employee lifecycle from recruiting to offboarding. We're shifting from standard SaaS solutions to building scalable, secure platform infrastructure — data APIs, AI agents, and integration frameworks — so our People teams can build more. Reporting to the Head of People Technology, you'll join a team that builds and stewards the system architecture, entitlements, and integrations connecting our People platforms — starting with Talent Acquisition and expanding across the broader People portfolio. Together, your team is the technical backbone that lets People Operations teams safely configure and build on top of well-designed systems, rather than configuring those systems day to day themselves. You Will Platform Architecture & Integrations Help design and own the system architecture connecting Workday, Greenhouse, and other People platforms, including entitlements, security roles, data models, and integration patterns (APIs, middleware, ETL). Build and maintain integrations and data flows that People teams and Operations partners can rely on, build from, and extend easily. Evaluate and manage People Technology vendors and platforms, weighing build, buy, and integration tradeoffs. Enablement & Reusable Tooling Build MCPs, data services, and other reusable tools that make People systems more accessible and configurable for non-engineers — the underlying plumbing that lets Talent Operations and other People teams build on trusted, governed foundations. Partner with Talent Acquisition and other People teams to understand what they need to configure or build themselves, and deliver the data fields, security roles, and integration points that make it possible. Advise on and help design solutions with People teams as they evaluate configuration or automation options, making sure what they build sits on solid architecture. AI, Automation & Innovation Use AI and modern development tools to prototype, automate, and deliver integration and data solutions that improve reliability and speed. Evaluate emerging technologies and identify opportunities to strengthen the platform's architecture and operational effectiveness. Platform Operations & Governance Steward the technical health of our People systems of record, including Workday and Greenhouse, ensuring integrations, data flows, and access models are reliable, secure, and scalable. You Have 5+ years of related experience with a Bachelor's degree; or 3 years and a Master's degree; or a PhD without experience; or equivalent work experience. Hands-on experience designing and building Workday integrations, data flows, and system architecture using Workday's integration toolset (e.g., EIBs, Workday Studio, Core Connectors, web services/APIs) and middleware/ETL platforms that connect to it. Hands-on experience defining and managing security roles, entitlements, or access models within complex enterprise systems. A background in enterprise applications, platform engineering, or IT systems — you've been the technical owner of how systems are built and connected, not primarily the one gathering requirements or configuring out-of-the-box features. Experimented with AI tools to automate work or build solutions, and can talk through what you tried, what you learned, and how you'd apply it to People Technology challenges. We're all learning, but you need to have started. Led technical initiatives end-to-end — from architecture and design through implementation and adoption — for systems used by non-technical business partners. Translate technical concepts for business stakeholders and business needs for technical audiences, and influence decisions across People, Security, Data, and Engineering teams. Understanding of compliance and security standards relevant to enterprise systems (SOX controls, GDPR, data classification frameworks, access controls).

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.

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.

Block is one company built from many blocks, all united by the same purpose of economic empowerment. The blocks that form our foundational teams — People, Finance, Counsel, Hardware, Information Security, Platform Infrastructure Engineering, and more — provide support and guidance at the corporate level. They work across business groups and around the globe, spanning time zones and disciplines to develop inclusive People policies, forecast finances, give legal counsel, safeguard systems, nurture new initiatives, and more. Every challenge creates possibilities, and we need different perspectives to see them all. Bring yours to Block. The Role Square Financial Services, Inc. (SFS) is Block’s bank. We opened in March 2021 and provide lending and FDIC-insured deposit products to individuals and small businesses on a nationwide basis. SFS Risk Management is scaling vendor security, third party risk, and business continuity through innovation. Our Risk team designs and promotes the frameworks, standards, and oversight that elevates security considerations among our vendors, simplifies our regulatory obligations, and ensures resilience in our business operations. The team also operates the agent-first platforms that turn those frameworks into running systems. Most of governance is a data problem. The risk, control, and asset information needed to answer "are we secure and compliant?" is dispersed across dozens of systems: Security Engineers treat that as an engineering problem. You'll build the data pipelines, integrations, and agentic AI workflows that turn manual governance processes into products that run continuously, produce measurable results, and hold up to audit end to end. You Will Own and operationalize a SFS third-party risk management and business continuity program program. Define the technical approach for ambiguous, cross-team problem spaces. This is an early-stage program, and you will frame problems as often as you solve them. Build and operate the pipelines and integrations that aggregate, normalize, and join risk, control, and asset signals from systems of record across Block and SFS, including source control, the service registry, identity, ticketing, and data platforms. Translate standards and compliance requirements into policy-as-code: enforceable, testable rules that run continuously. For example, "every production service has an accountable owner" becomes a versioned, tested check instead of a quarterly spreadsheet. Design agentic AI workflows that pair LLM reasoning with deterministic, auditable decision layers for evidence analysis, control monitoring, classification, and assessment. Automate evidence collection and continuous control monitoring to replace point-in-time audit preparation.
