Senior AI Engineer - (LLMs / RAG / Agentic Systems) - Aerospace - NYC - $350k+ Equity $200,000.00/yr - $400,000.00/yr

We’re hiring for a world class team at one of the fastest growing & most innovative

next-gen aerospace AI companies

in North America. They're building

LLMs, RAG & high-performance AI systems

to power mission-critical operations in defence & space.

The Role You’ll own & scale a

RAG-driven AI system

powering critical aerospace operations. Expect to tackle

retrieval quality, latency bottlenecks, & eval-driven fine-tuning

head-on for the most innovative & exciting real-time systems in Aerospace today. This is full production ownership – from architecture to metrics.

You should have experience with:

Deploying

LLM-based systems

at scale (Llama, Mistral, GPT-4, Claude)

Retrieval optimisation

– hybrid search (BM25 + vector), reranking, caching

Evaluation

– recall@k, precision@k, groundedness, hallucination metrics

Fine-tuning (LoRA/QLoRA), RAG architecture, LangChain / LlamaIndex

Bonus:

IoT or Hardware integration or real-time systems experience exp.

Ideal background:

CS or Applied ML degree from a top-tier university

Proven 0-1 experience in a fast-moving AI startup, or Defence related company

You’ve shipped reliable GenAI systems under pressure

Prior experience in high-performance teams (0-1, startups)

You’ll be expected to:

Own the

LLM pipeline end-to-end

– retrieval → evaluation → fine-tuning

Improve

accuracy, grounding, and eval metrics

continuously

Make architecture decisions for scale, reliability & speed

Collaborate directly with

founders & domain experts

Stack:

LLM-based systems, RAG architecture, LangChain / LlamaIndex, evaluation pipelines, fine-tuning, caching, hybrid search, vector embeddings, real-time inference.

Offer:

Up to $350,000+ base salary + equity

On-site in NYC

Tight-knit, high-output team

High ownership, real impact, flat structure

Interview Process: 1) Technical Deep Dive

TL;DR - Senior AI Engineer (NYC, On-site)

Build & scale

production-grade GenAI systems

from

0 to 1

Own and improve

RAG pipelines

– accuracy and latency matter

Deep experience with

LLMs, LangChain, Hugging Face

& real deployments

Must have shipped

working GenAI products , not just prototypes

$350K+ base + equity –
