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 We build AI products, and the quality of our evaluations sets the ceiling for how good those products can be. The speed of our evaluations determines how quickly we can improve them. We are looking for an engineer to build the infrastructure and tooling that make high-quality AI evaluation possible at Block's scale. You will help teams understand whether a model or product change is actually better, whether a result is statistically meaningful, and whether offline evaluation is predicting what happens with real users. Our evaluation approach combines offline evals that encode our definition of a good response, online evals that show how people actually respond, and a feedback loop that keeps the two converging. Your work will turn that approach into systems that product teams can use quickly, reliably, and with confidence. This is a high-impact, early-stage area with broad surface area. You will help decide what to build first, then build the platform that helps teams ship better AI products faster. You Will Build an execution engine that can score candidate versions against task sets in minutes, not hours. Create task set tooling that samples from production logs and validates tasks before they are admitted into an evaluation set. Build grader infrastructure across ground truth checks, rubrics, and LLM-as-judge approaches. Develop tooling that helps human reviewers calibrate judges, measure judge-to-human agreement, and monitor drift over time. Build leaderboards and reporting systems that include sample size, confidence intervals, and run-to-run variance, so teams can distinguish real improvements from noise. Support in-product side-by-side serving, feedback capture, and implicit signal extraction from real conversations. Build the loop that compares offline scores with online outcomes, identifies eval sets that have stopped predicting reality, and helps teams improve them. Partner with product, engineering, data, and ML teams to make evaluation workflows fast enough and trustworthy enough to become part of everyday development. You Have Experience building production platforms or infrastructure, including distributed batch execution, data pipelines, or systems that process production logs. Strong statistical literacy, including comfort with confidence intervals, variance, power, and multiple comparisons. The judgment to identify when a result is meaningful and when it is noise. Experience evaluating LLM or ML systems, or deep systems engineering experience with a strong interest in AI evaluation. Product instinct for internal tools. You understand that leaderboards, annotation tools, and workflows only matter if teams actually use them. A bias toward building reliable, observable systems that other engineers can trust. Strong collaboration skills and the ability to work across ambiguous product, data, and engineering problems. Success in your first year Product teams can stand up credible evals for new AI surfaces in days. Eval results gate CI and run quickly enough that engineers do not route around them. Judge-to-human agreement is measured, published, and monitored for drift. Launch decisions are not made on results that are within statistical noise. At least one case is documented where online reality disagreed with offline scores, and the evaluation was improved as a result. Why this matters AI product development moves quickly, but speed only helps when teams can trust the signal they are using to make decisions. This role will build the systems that make those signals faster, more accurate, and more actionable. Your work will directly influence how Block evaluates, improves, and ships AI products.

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.

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.
