Block is looking to advance the next generation of AI-assisted development by integrating AI throughout the software development lifecycle to make development faster, more creative, and more reliable through intelligent, AI-driven tooling.
Requirements
- 12+ years of experience building and shipping production systems.
- Strong software engineering background, with fluency in designing scalable backend systems.
- Deep understanding of LLMs, prompt engineering, and applied ML workflows from experimentation and evaluation to deployment and monitoring.
- Experience integrating third-party AI models (e.g., OpenAI, Anthropic, or custom fine-tuned models) into real-world tools or services.
- A pragmatic approach to experimentation and iteration, balancing innovation with reliability and security.
- Familiarity with developer ecosystems, IDEs, or productivity platforms is a plus (e.g., VS Code, Cursor, GitHub Copilot, etc.).
Responsibilities
- Design and build AI-driven developer tools that integrate seamlessly into the software development lifecycle (e.g., intelligent code assistance, inline reviews, or automated refactoring systems).
- Partner with vendors and internal teams to evaluate, integrate, and optimize AI engineering tools.
- Collaborate with engineering leaders across Block to identify opportunities for AI integration that improve developer velocity and code quality.
- Mentor engineers, contribute to design and code reviews, and help establish best practices for building reliable AI systems at scale.
- Work across AI infrastructure and developer tooling to build and optimize coding agents that empower engineers company-wide.
- Collaborate with platform and product teams to refine user experiences, introduce new capabilities, and improve the performance of coding agents.
- Continuously improve AI coding agents across all Block repositories, enhancing their ability to understand context, complete tasks, and assist with real-world development workflows.
Other
- Strong communication and cross-functional collaboration skills, especially with engineers, product managers, and leadership.
- We will consider qualified applicants with arrest or conviction records for employment in accordance with state and local laws and “fair chance” ordinances.
