Full Job Description

📋 Description

• Design and build production-grade AI systems including agentic workflows, RAG pipelines, and LLM-powered applications that integrate into FICO’s analytics and decision management platform.
• Translate product requirements into technical designs that balance model capabilities, latency, cost, and reliability against real-world business constraints.
• Develop robust evaluation frameworks and benchmarks to measure quality, safety, and regression across LLM-based features, using signals to drive iterative improvement.
• Drive end-to-end delivery of AI features including prompt and context engineering, tool/function design, writing reusable and well-tested code, running offline and online evaluations, and communicating results to stakeholders.
• Build and operate the application layer around foundation models: orchestration, tool use, memory, retrieval, guardrails, observability, and human-in-the-loop workflows.
• Fine-tune, distill, and adapt open and closed foundation models when warranted, aligning technical choices with FICO’s product strategy and roadmap.
• Optimize inference performance, throughput, and cost across the serving stack using caching, batching, routing, and model selection strategies.
• Apply modern AI engineering practices across heterogeneous infrastructure, including CPU-bound orchestration services and GPU-accelerated inference and training workloads.
• Design and deploy LLM-based features in production with hands-on experience in prompt engineering, tool/function calling, agentic workflows, and evaluation-driven iteration.
• Implement embeddings and information retrieval systems with hands-on experience using Retrieval-Augmented Generation (RAG) architectures and vector stores such as Pinecone, Weaviate, or pgvector.
• Build offline and online evaluation pipelines for AI systems by defining metrics, constructing eval sets, running A/B tests, and using performance signals to guide product improvements.
• Collaborate effectively across engineering, product, and data science teams, mentoring peers and influencing technical direction with strong communication and problem-solving skills.
• Ensure high standards of reliability, evaluation rigor, and responsible AI governance across all AI initiatives shipped to FICO’s platform.
• Work within a high-caliber, multidisciplinary team to innovate through deep expertise in applied AI, software engineering, and systems design.

🎯 Requirements

• 7+ years of software engineering experience with at least 1+ years building production applications powered by LLMs or foundation models
• Hands-on experience designing and deploying LLM-based features in production including prompt and context engineering, tool/function calling, agentic workflows, and evaluation-driven iteration
• Strong coding skills in Python and/or TypeScript with experience using modern AI SDKs and frameworks (e.g., Anthropic, OpenAI, Google SDKs; LangChain, LlamaIndex, LangGraph; MCP)
• Solid working knowledge of production LLM system architectural patterns including orchestration, tool use, memory, guardrails, observability, caching, and cost/latency optimization
• Experience with embeddings, information retrieval, and RAG architectures using vector stores such as Pinecone, Weaviate, or pgvector
• Experience building offline and online evaluation pipelines for AI systems, including defining metrics, creating eval sets, running A/B tests, and driving iterative improvement

🏖️ Benefits

• Highly competitive compensation range of $140,000 to $220,000 base pay
• Inclusive culture rooted in core values: Act Like an Owner, Delight Our Customers, Earn the Respect of Others
• Opportunity to develop professionally through learning experiences and impactful work on AI-driven solutions used globally
• Engaging, people-first work environment with work/life balance, employee resource groups, and social events
