• Build software that exercises and integrates advanced AI model capabilities across end-to-end workflows
• Integrate model APIs into production-ready applications, including supporting infrastructure such as tool interfaces, evaluation frameworks, monitoring, and telemetry
• Develop scalable backend services and APIs while contributing to modern front-end applications
• Investigate and troubleshoot model, application, and integration issues, documenting failure modes and technical findings clearly
• Translate engineering observations into actionable feedback for research and engineering teams
• Rapidly prototype solutions and deliver functional increments in environments with evolving requirements and limited initial specifications
• Collaborate with engineering managers and fellow developers to maintain high standards for code quality, architecture, testing, and technical documentation
• Work across unfamiliar systems and codebases, quickly identifying dependencies and implementing effective solutions

Skills

• * 3+ years of professional experience building and deploying production software in a high-quality engineering environment
• * Strong production experience in at least one of Python, Java, Rust, C#, or C++, along with working proficiency in a second programming language
