As a Senior AI Engineer at Factored, you will engage full-time in designing and building production-grade GenAI systems that transform enterprise AI strategies into secure, scalable applications. You are a hands-on engineer working directly with client teams, shipping production code while contributing to technical strategy and learning from experienced leaders. You own complex, high-impact projects from architecture through optimization and deployment.

This role exists for engineers who want to build at the frontier of AI while growing their technical expertise.

• Architect, design, and implement backend systems that integrate with LLMs, and ensure services are scalable, secure, and production-ready
• Implement agentic architectures for complex AI workflows.
• Build, deploy, and manage cloud-native AI applications on AWS (Lambda, ECS, Sage Maker) and other modern infrastructure.
• Fine-tune prompts and build RAG pipelines to optimize performance.
• Implement AI security guardrails and conduct risk assessments to ensure compliance, privacy, and safety.
• Monitor application health with observability tools (APM, logging, LLM performance metrics) and proactively resolve performance issues.
• Collaborate with ML Engineers, product managers, and cross-functional teams to understand requirements and deliver AI features that drive measurable value.
• Communicate technical architecture and trade-offs clearly to stakeholders at all levels.
• Contribute to raising
  engineering
  standards through code review and knowledge sharing.

• 5+ years of professional experience as a Software Engineer or in a related role, with a strong foundation in Python.
• Hands-on experience or strong interest in Generative AI frameworks such as Lang Graph, Lang Chain, OpenAI, and RAG implementations.
