Software Engineer, Justice Engineering

Block is a technology company focused on economic empowerment through financial and commerce products. The Justice Engineering team is seeking a Software Engineer to design, build, and operate full-stack services that automate responses to legal, regulatory, and civil requests, including backend systems, internal tools, and data pipelines. The role also involves operational ownership, collaboration with Counsel and Compliance, and exploring AI-powered workflows.

Responsibilities:

• Partner closely with your team to design, develop, test, ship, and maintain features that automate how Block responds to legal, regulatory, and civil requests
• Write high-quality, well-tested code, and participate actively in design reviews and code reviews
• Design and implement systems that work within our microservice and event-driven architectures, handling highly sensitive customer data with the care and correctness that legal obligations demand
• Partner directly with Counsel, Compliance, and Operations to translate nuanced legal requirements into durable automated workflows
• Participate in operational ownership of engineering systems, including on-call, incident response, and postmortems
• Reduce toil and modernize services that grew quickly, leaving each one more reliable than you found it
• Demonstrate AI fluency by leveraging AI-powered tools throughout the development lifecycle to improve velocity and quality, while applying sound judgment in their use
• Hold your teammates — and yourself — to high engineering standards
• Learn from and support other engineers through code reviews and technical discussion

Requirements:

• 3+ years of software development or equivalent experience
• Experience building and maintaining production software systems, and delivering well-scoped projects or features end-to-end (design, build, test, ship, operate) with guidance from more experienced engineers
• Worked across the stack, on backend services and on the interfaces people use to operate them
• Drive to find flaws in a system with many moving parts and take whatever steps are necessary to fix them
• Curiosity about problems that arrive only partly specified, and a habit of asking the questions that make them concrete
• A track record of explaining technical tradeoffs in writing and in person, to engineers and non-engineers alike
• Demonstrated AI fluency, including experience using AI-powered developer tools and the ability to critically evaluate and responsibly apply their outputs
• Bachelor's Degree or Diploma in Computer Science, Computer Engineering, Software Engineering, or equivalent experience
• Experience working with sensitive data (PII, PCI) or building to privacy, security, or regulatory requirements
• Experience building internal tools, operational workflows, or case management systems
• Experience integrating LLMs or agents into production workflows
• Experience modernizing a long-lived, business-critical service
• Interest in legal, compliance, or investigations technology is a plus — deep domain expertise is not required; we'll teach you
