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. 

• Further the Sage Engineering team’s technical capabilities by bringing novel methods from the field into Red Ventures through hands-on prototyping, software development, and teaching others—leaving the woodpile higher than you found it. 

• Drive the development of junior team members through mentorship and coaching. 

  

What We’re Looking For:

• 5+ years building and shipping production software, with at least 1 year building LLM-powered systems. BS/MS in CS, ML, or a related field preferred; equivalent applied experience welcome in lieu of a degree. 

• Demonstrated experience shipping LLM-powered products to production, including hands-on work with prompt design, agent harnesses, and tool use. 

• Hands-on experience building eval frameworks—benchmark design, golden dataset curation, LLM-as-judge, and regression testing for prompts and models. 

• Experience selecting and integrating foundation models from multiple vendors (Anthropic, OpenAI, open-weight models), and reasoning about cost, latency, and quality tradeoffs. 

• Familiarity with post-training techniques (SFT, DPO, LoRA) and RAG/retrieval system design, including embedding model selection. Comfort operating in a regulated/financial environment is a plus. 

• Experience with end-to-end model development, deployment, evaluation, and monitoring workflows, including LLM-based products in production. 

• Proficiency with a modern data platform (Databricks, Snowflake, or similar). 

• Familiarity with TypeScript/React/Node a plus, for app integration (nice-to-have). 

• Ability to methodically understand business context, define value propositions, and formulate and solve complex applied AI problems. 

• Ability to clearly articulate the “why” behind proposed AI solutions to relevant stakeholders. 

• Ability to own key deliverables and use problem-solving to deliver projects on time, iterating when justified by incremental value—because plan beats no plan. 

• Ability to intake business requests and priorities, prioritize bodies of work, and communicate project status, timeline, and technical results to broad audiences. 

• Bias to action and proactive communication—every second counts. 

• Experience expanding the knowledge of an AI engineering team through teaching and mentoring on topics where you have specific expertise. 

• Experience leveraging technical expertise to identify the feasibility of potential AI projects, ensuring the team delivers value on projects that are feasible. 

• Stays current on the rapidly evolving AI landscape and translates new techniques, models, and tooling into shipped product—a commitment to getting better every day.
