60 Block Software Engineer Jobs Hiring Near You

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.

At Block, we strive to build the best products in the world - including the ones our customers never see. The Justice Engineering team builds the systems Block uses to meet its legal obligations to law enforcement, courts, and government agencies.

Every month, Block receives thousands of subpoenas, civil notices, tax levies, liens, and receiverships. Getting each one right matters in both directions: responding late or incompletely exposes Block to financial, criminal, and reputational penalties, while producing more data than a request calls for breaks the trust our customers place in us. Our services automate that work end to end - identifying the right customer from a fragment of data, assembling and securely delivering records, freezing and releasing accounts, moving money, and notifying customers - for the Counsel and Compliance teams who respond to these requests on Block's behalf.

As a full stack software engineer on Justice Engineering, you will design, build, and operate these services. We're a small team with a large surface area, so the scope is real: you'll own well-scoped features end to end - from design through testing, launch, and operation - across backend services, the internal web tools our partners work in, and the pipelines that connect us to dozens of upstream systems across Block. You'll also help shape where we're going next: LLM-powered agents that read and triage incoming legal requests, a secure portal for verified external requesters, and the evolution of our tools into a platform other Block teams build on.

• 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

• 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

Even better:

• 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.

• Java, Kotlin
• React, TypeScript
