Sage Home Loans is on a mission to revolutionize the industry by making mortgage simple. We’re re-imagining the mortgage application and origination processes around data and AI systems, and we’re hiring a Senior AI Engineer to join our Innovation team. In this role, you’ll work hands-on with cutting-edge generative AI technologies—partnering with AI engineers, software engineers, and product managers to build LLM-powered products that meaningfully change how mortgages get done. We’re looking for a builder with a bias to action who thinks like an owner, brings a growth mindset, and is energized by the chance to ship production AI in a regulated, fast-moving environment. 

What You’ll Do:

• Work with cutting-edge generative AI technologies such as LLMs and collaborate with other highly talented AI and software engineers. 

• Help build and improve AI-enabled products such as automated document processing, auto condition clearing, income calculation, call scoring, and virtual assistants. 

• Design and own our AI eval infrastructure—golden datasets, automated regression suites, LLM-as-judge pipelines, and online quality metrics for our LLM-powered products. 

• Lead model, harness, and training decisions across the AI stack—foundation model selection across vendors, agent frameworks and orchestration, custom fine-tuning (SFT, DPO, LoRA), and RAG/retrieval design. 

• Design safety guardrails, hallucination mitigation, and PII handling appropriate to regulated mortgage workflows—because we believe in winning the right way. 

• Design and execute end-to-end AI systems with attention to reliability, latency, cost, and observability in production. 

• Take ideas from discovery to production solutions—thinking big, starting small, and scaling fast. 

• Partner with business stakeholders and work effectively across business, creative, and engineering groups to solve problems and build a positive culture across teams. 

• Provide guidance to the broader applied AI community within Red Ventures on the design and execution of AI projects, especially where you bring specific expertise.
