Block builds simple, powerful tools that make progress towards an economy that’s truly open to all. Each of our brands unlocks different aspects of the economy for more people. Square makes commerce and financial services accessible to sellers. Cash App is the easy way to spend, send, and store money. Afterpay is transforming the way customers manage their spending over time. TIDAL is a music platform that empowers artists to thrive as entrepreneurs. Bitkey is a simple self-custody wallet built for bitcoin. Proto is a suite of bitcoin mining products and services. Together, we’re helping build a financial system that is open to everyone. Join us. The Role The AI & DX (Developer Experience) Analytics team exists to measure and improve Block's developer experience and investment in AI. We turn raw engineering signals (agent session data, pull request and CI activity, and AI spend) into reporting and analysis that shape leadership's AI investment decisions, and drive improvement in AI ROI and developer experience. Your work will be the trusted source of truth that engineers and executives use to decide where AI investment is working and where to redirect it. We're hiring a Senior Analytics Engineer to own parts of that pipeline end to end. This is a broad, high-visibility role with a lot of white space: you will instrument new telemetry at the source and build production pipelines that turn it into governed data, then turn that governed data into executive-facing reporting and the analysis that surfaces concrete opportunities to improve AI ROI and developer experience. You'll also help pioneer one of the most consequential open problems in the industry right now: measuring the productivity impact of an increasingly AI- and agent-augmented engineering workforce, where there is no textbook answer and real room to set the standard. You'll define new metrics and craft the visual narrative — the charts, dashboards, and presentation materials — that make them land with an executive audience. AI-first workflows are central to how this team operates and critical to succeeding in this role: using AI coding agents is a default part of how you build and maintain pipelines and dashboards. You'll excel in this role if you're as comfortable defining and visualizing a brand new executive-facing metric from a messy signal as you are debugging why a pipeline silently stalled overnight. You Will Instrumentation & Telemetry: Instrument and extend the raw telemetry captured about AI usage, code changes, CI/CD activity, and spend — building new data capture, not only transforming what already exists. This is core to the role, as evolving AI tools and increased AI adoption constantly creates new signals that need to be captured. Partner with data engineers on production ETL pipelines that land that telemetry into governed tables, with the freshness monitoring, backfills, and alerting that keep it trustworthy, rather than a one-off script. Define new metrics out of ambiguous or evolving signals, and earn stakeholder trust in a new number by validating and reconciling it until it holds up. Dashboards & analysis: Build and ship the executive-facing dashboards and visualizations that turn governed metrics into decision-ready reporting — with the polish and precision a room of executives will scrutinize. Run the analysis that a new chart or metric needs and anticipate questions that an executive audience will ask, then bring senior stakeholders a recommendation, not just a number, and defend the methodology behind both. Translate complex, technical findings into a clear narrative: the headline chart and the one sentence that makes an executive act on it. Across both: Use AI coding agents as a default part of how you write, test, and maintain data pipelines, dashboards, and analyses. Partner across data engineering, applied AI, and data science teams to keep telemetry connected end to end — the raw signal you capture directly feeds the session classifiers, not just the dashboards you build. Turn what the data shows into action: flag where AI spend isn't paying off or where developer friction is most costly, and push the tooling, process, or investment changes that address it. Push the industry-frontier work of quantifying AI and agent productivity impact — there's no established playbook, and this team sets one. Qualifications You are: Self-sufficient across the full analytics loop: instrumentation, pipeline building, metric definition, and dashboards — not someone who hands off past the query. At home in messy, evolving telemetry, with the judgment to know when a new number is right and when it needs a second look before an executive sees it. A strong product thinker: you get at what a stakeholder actually needs from a metric or chart, not just what they asked for. Comfortable with ambiguity on a genuinely unsolved problem — measuring AI/agent productivity impact — and motivated to go set the standard rather than wait for one. An exceptional communicator, able to defend a metric's methodology and a chart's framing directly to senior stakeholders. Thoughtful about using AI coding agents in your own craft: fast to build with them, and rigorous about evaluating what they produce rather than taking it on faith. You have: 8+ years in analytics engineering, data engineering, or business intelligence, owning production data pipelines and insights end to end. Strong SQL and Python, with hands-on experience building and operating data pipelines against a cloud data warehouse such as Snowflake. Experience partnering with engineering teams to instrument new event or telemetry data, not only transforming what's already captured. Experience building dashboards or internal tools that non-technical stakeholders rely on to make decisions. Comfort with git, CI/CD systems, and debugging production pipeline failures such as retries and backfills. Even better: Experience with a metrics-governance or semantic-layer system, such as a metrics store, dbt semantic layer, or LookML. Technologies we use and teach: SQL (Snowflake), Python, TypeScript and React, Git, CI/CD pipelines, a governed metrics store, AI coding agents, and LLM-based classification tooling.

The Role The AI & DX (Developer Experience) Analytics team exists to measure and improve Block's developer experience and investment in AI. We turn raw engineering signals (agent session data, pull request and CI activity, and AI spend) into reporting and analysis that shape leadership's AI investment decisions, and drive improvement in AI ROI and developer experience. Your work will be the trusted source of truth that engineers and executives use to decide where AI investment is working and where to redirect it. We're hiring a Senior Analytics Engineer to own parts of that pipeline end to end. This is a broad, high-visibility role with a lot of white space: you will instrument new telemetry at the source and build production pipelines that turn it into governed data, then turn that governed data into executive-facing reporting and the analysis that surfaces concrete opportunities to improve AI ROI and developer experience. You'll also help pioneer one of the most consequential open problems in the industry right now: measuring the productivity impact of an increasingly AI- and agent-augmented engineering workforce, where there is no textbook answer and real room to set the standard. You'll define new metrics and craft the visual narrative — the charts, dashboards, and presentation materials — that make them land with an executive audience. AI-first workflows are central to how this team operates and critical to succeeding in this role: using AI coding agents is a default part of how you build and maintain pipelines and dashboards.

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. We’re working to build a more inclusive economy where our customers have equal access to opportunity, and we strive to live by these same values in building our workplace.
