Ethos was built to make it faster and easier to get life insurance for the next million families. Our approach blends industry expertise, technology, and the human touch to find you the right policy to protect your loved ones.
We leverage deep technology and data science to streamline the life insurance process, making it more accessible and convenient. Using predictive analytics, we are able to transform a traditionally multi-week process into a modern digital experience for our users that can take just minutes! We’ve issued billions in coverage each month and eliminated the traditional barriers, ushering the industry into the modern age. Our full-stack technology platform is the backbone of family financial health.
We make getting life insurance easier, faster and better for everyone.
Our investors include General Catalyst, Sequoia Capital, Accel Partners, Google Ventures, SoftBank, and the investment vehicles of Jay-Z, Kevin Durant, Robert Downey Jr and others. This year, we were named on CB Insights' Global Insurtech 50 list and BuiltIn's Top 100 Midsize Companies in San Francisco. We are scaling quickly and looking for passionate people to protect the next million families!
We’re building several LLM-powered copilots across critical workflows (e.g., underwriting productivity, agent enablement, customer support, operations/compliance, fraud). We need an AI engineer to own the LLM + retrieval + context layer that makes these copilots accurate, auditable, fast, and cost-efficient.
Typical stack: Python/FastAPI, Postgres + vector (pgvector/Pinecone/Weaviate), OpenSearch, optional graph DB, Kubernetes + GPUs, OTEL/Datadog
Duties and Responsibilities:- Production RAG: indexing, retrieval, hybrid search, reranking, query rewriting, grounding, citations
- Context Graph: entity resolution + linking + provenance; graph + vector retrieval; supports multi-hop context
- LLM orchestration: tool/function calling, structured outputs, routing across model tiers, failure modes
- GPU/inference cost optimization: batching, caching/KV reuse, quantization, autoscaling; optimize $/session + latency
- Safety + compliance: PII/PHI handling, redaction, audit logs, deterministic replay, hallucination mitigation
- LLMOps: eval harness (golden sets, regression, adversarial), monitoring for quality/cost/drift
- Design/ship the end-to-end pipeline: retrieve → assemble context → generate → cite → log/monitor
- Improve quality and trust via evaluation, feedback loops, and clear evidence-backed outputs
- Partner with product, security, and domain teams; write crisp design docs; raise engineering bar
- Ship RAG v1 with citations + measurable quality metrics
- Deliver Context Graph v1 that improves retrieval on real copilot tasks
- Reduce cost/latency with a concrete inference optimization plan shipped to prod
- 7+ years building production systems; 2+ years hands-on LLMs/RAG
- Proven RAG experience (embeddings, vector DBs, hybrid search, reranking, eval)
- Strong backend/distributed systems + observability
- Track record shipping in high-stakes environments with auditability/correctness
- Knowledge graph / entity resolution / provenance systems
- GPU inference optimization (vLLM/TGI/TensorRT-LLM, quantization AWQ/GPTQ, batching)
- Regulated domain experience (insurance/fintech/healthcare)
