Note: The job is a remote job and is open to candidates in USA. Durlston Partners is a top-tier global crypto exchange building a new US-based R&D center and hiring a founding Senior Applied AI Engineer. The role involves shipping production LLM applications and owning the architecture end to end, contributing to a hands-on individual-contributor position in a greenfield environment.
Responsibilities
- Production LLM applications and multi-agent systems serving real external users at scale
- RAG pipelines and retrieval systems against large, messy, real-world data
- Agent orchestration using modern frameworks, with tool use, memory, and reliability engineering
- Evaluation harnesses (regression suites, LLM-as-judge, golden sets) that keep quality measurable as the system evolves
- The reference architecture and engineering standards for a growing applied-AI team
Skills
- You have shipped at least one production LLM or agent system that real external users depend on at meaningful scale. Not a prototype, not an internal demo, not a proof of concept
- Strong production Python. You write the code, not just the architecture diagrams
- Direct experience with multi-agent systems, RAG, and at least one agent framework in production
- You have built evaluation infrastructure yourself, not only set eval 'practices' for others
- You use AI coding agents daily as part of your real workflow
- You can operate as a founding IC: high ownership, high autonomy, comfortable with ambiguity and speed
- Fintech, crypto, or other high-stakes / regulated production environments
- Experience being the first or one of the first AI engineers on a team or product
Benefits
- Additional token upside is speculative and not guaranteed.
