Software Engineer, Artificial Intelligence/LLM (Multiple Seniority Levels)
ABOUT BEACON AI
We’re a fast-moving team of aviators, engineers, and operators building an AI platform to make flying safer, more efficient, and more capable. Backed by top investors, we’ve secured a dozen Department of Defense contracts and partnered with major airlines to deliver mission-critical systems. We operate without silos or heavy processes. Small, focused teams own what they build, ship quickly, and learn fast, pushing the boundaries of how humans and AI work together in aviation.
You will ship LLM-powered product features end-to-end. That means designing retrieval and tool-calling flows, writing the services that run them, building evals and guardrails, and watching cost, latency, and quality in production. You’ll partner with the ML/infra teammates on embeddings, indexing, and model hosting, and with the product teammates on user experience and outcomes. We move fast, and we care about reliability in a safety-critical domain.
We’re hiring across levels. Senior engineers own features and services. Staff engineers own systems, standards, and cross-team technical direction.
WHAT YOU’LL DO
Build user-facing LLM features
- Design and implement retrieval-augmented generation and tool-calling flows using frameworks like LangChain or equivalent primitives, where simpler is better.
- Deliver robust JSON and schema-bound outputs with validation, retries, and fallbacks.
- Add function calling to integrate with internal tools, search, routing, and data services.
Own the service layer
- Ship APIs and workers in Python or TypeScript with clear contracts, streaming, and backoff.
- Add caching, request shaping, prompt templates, and context packing to control latency and cost.
- Integrate with AWS Bedrock, OpenAI, Anthropic, or self-hosted endpoints as needed.
Retrieval and data prep
- Collaborate with infrastructure teammates to develop chunking, embeddings, and indexing capabilities for documents, time series, and multimedia.
