About Galaxy Galaxy is a global leader in digital assets and AI infrastructure, delivering solutions that accelerate progress in finance and artificial intelligence. Founded in 2018 and headquartered in New York City, we serve institutions, startups, protocols, and investors across a platform spanning trading, asset management, tokenization, and large-scale AI and high-performance computing data centers. This role sits on the AI products team, a small, high-ownership group that takes ideas from prototype to production and ships them at scale.
Why you'll want this role • Greenfield, high-ownership work: build new AI products end to end, rather than maintaining legacy systems. • Real impact: your work ships to institutional and individual clients and runs in production, not stuck in prototype. • Modern stack: hands-on with LLMs, agentic systems, and AWS-native AI services. Role Overview As a Backend Engineer on our AI Products team, you will design, build, and operate the backend services that power products across Galaxy.
You will work with product and engineering teams to implement features end-to-end, from data model to API to production deployment. Many of these products integrate with Galaxy's AI Suite, our internal platform for Generative and Agentic AI, built on AWS Bedrock, AgentCore, and SageMaker. Day to day, you'll mostly be consuming that platform, calling its APIs, wiring LLM and RAG-based features into application logic, and reasoning about prompts and model behavior as part of building a good product, rather than building or owning the platform itself.
From time to time, though, you may be asked to contribute directly to the AI stack, so foundational AI knowledge is important. g. g. g. g. pgvector) for AI-powered search/retrieval features • Ability to evaluate AI feature quality from a product/UX lens (accuracy, latency, hallucination handling, graceful degradation), distinct from model-level evaluation owned by the AI Platform team Why Version 1?
