Agentic AI Engineer / Software Engineer - AI Applications (Remote US) ***US Citizenship or Greencard is required due to US Government contract requirements*** Job Summary: We're looking for an Agentic Engineer to bridge the gap between our AI platform and customer outcomes. You'll take the platform capabilities our engineering teams build—agents, workflows, memory, reasoning, integrations, and tools—and turn them into polished, customer-ready applications that demonstrate immediate value. This is an engineering role for someone who enjoys building end-to-end experiences. You'll work directly with product and platform engineers to rapidly build, iterate, and ship AI applications that align with real operational value. Responsibilities: Build agentic applications that solve real customer use cases using our platform capabilities. Design agentic workflows, plugins, and tool integrations that deliver measurable customer value. Translate ambiguous problems into intuitive AI experiences. Rapidly build new applications, gather feedback, and iterate into production-ready solutions. Partner closely with platform engineers to inform abstractions and reusable components. Identify common patterns across customer deployments and help evolve them into reusable products. Own customer-facing quality—from UX and reliability to performance and evaluation. Required Skills and Qualifications: Bachelor’s or Master’s degree in Computer Science, Artificial Intelligence, Engineering, or related discipline. 3-5 years of software engineering experience Experience building production-ready agentic AI applications using AI agents, workflows, MCP, and tool orchestration. Ability to move quickly from idea to working product while maintaining high engineering quality. Strong product instincts—you care about whether something is useful, not just technically impressive. Experience integrating APIs, enterprise systems, and external data sources. Excellent communication and collaboration across engineering and product teams Growth mindset and low ego- you’re eager to pick up new tools and technologies, learn from others, and be open to changing course when it’s right. Drive to foster a culture of collaboration, psychological safety, and technical excellence. Strong advocate for inclusion in technical discussions at all levels.
