About The Position

Block Information Security is an engineering-driven team focused on scaling security through innovation. Our Security Governance team designs and promotes the frameworks and standards that safeguard customer data, elevate security considerations across the company, and simplify regulatory and compliance obligations. The team also operates the agent-first platform that turns 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: source control, service registries, identity providers, data warehouses, ticketing, CI/CD. GRC 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.

Requirements

7+ years building production software in backend, platform, data, or security engineering
Multi-year ownership of a production system, including on-call, SLOs, and the maintenance work that starts after launch
Proficiency with at least one of Python, Kotlin, Java, or Go, and comfort reading unfamiliar codebases
Hands-on experience building with LLMs (prompting, tool use, agents, or LLM-backed features) and opinions about where model judgment belongs and where it doesn't. Judgment matters more here than volume
Experience with integration patterns: REST APIs, webhooks, authentication flows, event-driven architectures
Experience pulling, normalizing, and joining data from multiple imperfect sources, and handling the edge cases gracefully
Experience defining technical direction where the problem was ambiguous, and carrying it across team boundaries
Attention to detail balanced with pragmatism about risk-based prioritization

Nice To Haves

Working knowledge of a security or compliance framework such as PCI DSS, SOX, SOC 2, ISO 27001, or NIST. Prior GRC experience is not required; we can teach the governance side
Production-scale LLM or agentic systems experience

Responsibilities

Build and operate the pipelines and integrations that aggregate, normalize, and join risk, control, and asset signals from systems of record across Block, including source control, the service registry, identity, ticketing, data platforms, and CI/CD
Translate security 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
Build the evals, benchmarks, and calibration harnesses that keep automated governance honest
Automate evidence collection and continuous control monitoring to replace point-in-time audit preparation
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
Partner with Security Governance Partners, Compliance, and Engineering teams to find the manual processes most worth turning into product
Help govern Block's own AI systems: the same platform that automates governance also assesses the autonomy and safety of Block's agents
Contribute to technical design discussions, evaluating the security and reliability properties of the platform itself
