About the role
This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Staff Engineer / AI Builder based in the United States.
Join an innovative technology environment focused on designing and delivering advanced AI solutions that solve real-world business challenges. As a Staff Engineer / AI Builder, you will take technical ownership of the architecture, development, and deployment of production-grade AI and machine learning systems. You will lead the development of agentic workflows, generative AI applications, and scalable infrastructure, ensuring reliability, security, and performance. Working across backend, frontend, and cloud environments, you will transform complex technical requirements into practical solutions that create measurable value for clients. You will also play a key role in establishing engineering standards, mentoring colleagues, and influencing architectural decisions. This is an exciting opportunity to shape the future of enterprise AI through hands-on engineering, technical leadership, and close collaboration with multidisciplinary teams.
Accountabilities:
Requirements:
At least 6 years of professional software engineering experience, including substantial hands-on experience developing and deploying generative AI or LLM-powered systems in production environments. Strong practical expertise in agentic AI engineering, including reasoning loops, tool and function calling, and single-agent and multi-agent orchestration architectures. Ability to evaluate architectural approaches and explain when single-agent systems are more appropriate than multi-agent solutions. In-depth knowledge of RAG architectures, including document chunking strategies, embeddings, vector databases, OpenSearch or equivalent technologies, cosine similarity search, and re-ranking techniques. Experience building evaluation and observability frameworks for LLM applications, including golden datasets, LLM-as-judge methodologies, RAGAS or comparable evaluation metrics, and tracing platforms such as LangFuse or LangSmith. Advanced prompt engineering capabilities, with experience designing structured, production-ready system prompts that include clear instructions, constraints, and output requirements. Hands-on experience with the AWS generative AI ecosystem, particularly Bedrock, Agent Core, Lambda, DynamoDB, S3, SQS, EventBridge, and Step Functions. Strong programming skills in Python and Node.js, with experience developing backend services, full-stack applications, and RESTful APIs. Solid understanding of production reliability and resilience patterns for AI-powered systems, including retry mechanisms, exponential backoff, circuit breakers, and fallback model strategies. Experience with Docker, containerization, and cloud-native application deployment. Ability to independently manage complex, ambiguous, and integration-heavy engineering challenges, taking ownership from initial problem definition through production delivery. Strong analytical and problem-solving skills, combined with the ability to communicate complex technical decisions and justify architectural recommendations. Demonstrated technical leadership, mentoring capabilities, and the ability to collaborate effectively with multidisciplinary and distributed teams.Nice to Have:
Direct experience with Amazon Bedrock Agent Core, including agent registration, MCP tool integration, memory and session management, and gateway provisioning. Previous experience working in regulated or high-stakes industries such as healthcare, financial services, or education, where system reliability, security, and evaluation rigor are essential. Familiarity with workflow orchestration platforms such as AWS Step Functions, Sequencer, or similar state-machine-based technologies. Practical experience implementing and operating LLM observability tools in production environments. Experience delivering enterprise-grade AI solutions that integrate with complex business systems and operational workflows.
