Upstart is looking to solve the problem of expanding access to affordable credit by leveraging AI lending marketplace and improving the digital-first lending experience for its customers.
Requirements
- 6+ years of software engineering experience, with 2+ years working directly on ML-driven products or intelligent systems
- Proven ability to lead complex initiatives across engineering, product, and research stakeholders
- Strong backend development skills (e.g., Python with FastAPI or Flask), plus experience with cloud-native tooling (e.g., Kubernetes, Docker, Terraform)
- Experience integrating LLMs or ML models into production systems, including APIs and user-facing applications
- Experience shipping GenAI or LLM-powered features using frameworks like LangChain, LlamaIndex, or OpenAI APIs
- Familiarity with retrieval-augmented generation (RAG), vector search (e.g., FAISS, Pinecone), and real-time inference patterns
Responsibilities
- Design and build user-facing ML features that harness LLMs and generative AI to unlock new product capabilities
- Partner with product, design, and ML research to prototype and deliver high-impact, ML-powered experiences
- Own the technical architecture and implementation strategy for applied ML systems - balancing latency, observability, and iteration speed
- Build scalable services and APIs that bring model outputs to users in trustworthy and intuitive ways
- Collaborate across platform, infra, and legal/compliance teams to ensure ML deployments meet standards for safety, fairness, and performance
- Establish and evangelize best practices for prompt design, model evaluation, and experimentation across the org
Other
- Minimum 6+ years of software engineering experience
- Ability to think rigorously about system design, latency tradeoffs, and user impact when working with ML features
- Excellent communication skills and a collaborative, product-minded approach
- Travel Requirements: regular on-site collaboration sessions (3-4 days per Quarter) at one of our offices
- Time Zone Requirements: East/West Coast time zones
