AI Engineer (Mid-Level)

About the role

About the Role Join a fast-moving, pre-seed-backed AI startup building the next generation of agentic systems that automate complex, multi-step workflows across regulated and enterprise domains — including healthcare, legal, fintech, logistics, and compliance. As a mid-level AI Engineer on the core product team, you'll own production LLM-based services end-to-end, collaborate closely with founders and product, and ship features that deliver measurable impact for real users. What You'll Do • Design, build, and maintain agentic systems that automate complex, multi-step workflows across regulated industries. • Own production retrieval-augmented generation (RAG) pipelines and retrieval infrastructure, including vector databases, embeddings, and indexing for domain-specific search at scale. • Implement multi-agent orchestration, tool-calling, memory, and reasoning components to deliver robust AI-driven user experiences. • Develop evaluation and safety infrastructure to measure model performance, surface regressions, and enforce enterprise-level trust and reliability. • Ship full-stack AI products from MVP to enterprise-grade — designing APIs and data models, writing frontend and backend code, and operating production systems with CI/CD, monitoring, and testing. • Collaborate with founders, product, and design to prioritize work, define success metrics, and iterate based on user feedback and telemetry. What We're Looking For Must-haves: • 2–8 years of software engineering experience with demonstrated delivery of shipped user-facing or backend products. • Practical experience deploying LLMs or LLM-based services in production, including prompt design, orchestration, and tool integration. • Proficiency across the stack: Python plus TypeScript/React (or equivalent), cloud platforms (AWS or GCP), and relational or NoSQL databases. • Working knowledge of RAG patterns, vector databases, embeddings, and retrieval pipelines, with sound judgment on when to apply each approach. • Experience building automated tests, evaluations, and monitoring for AI systems to ensure reliability beyond demos. • Experience designing API-driven, high-throughput systems and real-time product features. Nice-to-haves: • Experience with agent or workflow frameworks (e.g., LangGraph, CrewAI) and orchestration tools (e.g., Temporal, Trigger). • Familiarity with fine-tuning, parameter-efficient tuning, or multi-modal model integration. • Background building multi-tenant or enterprise-ready systems, or prior experience in regulated industries such as healthcare, fintech, or legal. Compensation & Benefits • Salary: $180,000 – $400,000 USD annually (reflecting a wide band across base and equity depending on experience). • Early-stage equity in a venture-backed startup.
