Full-time

Job Summary

We're hiring a Generative AI Engineer with 6+ years across Data/ML/GenAI who can design, build, and productionize LLM-powered systems end-to-end. You'll select and fine-tune models (OpenAI, Anthropic, Google, Meta, open-source), craft robust RAG/agentic workflows (AutoGen, LangGraph, CrewAI, LangChain/LlamaIndex), and ship secure, observable services with FastAPI, Docker, and Kubernetes. You pair strong software engineering with MLOps/LLMOps rigor-evaluation, monitoring, safety/guardrails, and cost/latency optimization.

Key Responsibilities

Solution architecture:

Own E2E design for chat/agents, structured generation, summarization/classification, and workflow automation. Choose the right model vs. non-LLM alternatives and justify trade-offs. Prompting & tuning:

Build prompt stacks (system/task/tool), synthetic data pipelines, and fine-tune or LoRA adapters; apply instruction tuning/RLHF where warranted. Agentic systems:

Implement multi-agent/tool-calling workflows using AutoGen, LangGraph, CrewAI (state management, retries, tool safety, fallbacks, grounding). RAG at scale:

Stand up retrieval stacks with vector DBs (Pinecone/Faiss/Weaviate/pgvector), chunking and citation strategies, reranking, and caching; enforce traceability. APIs & deployment:

Ship FastAPI services, containerize (Docker), orchestrate (Kubernetes/Cloud Run), wire CI/CD and IaC; design SLAs/SLOs for reliability and cost. LLMOps & observability:

Instrument evals (unit/regression/AB), add tracing and metrics (Langfuse, LangSmith, OpenTelemetry), and manage model/version registries (MLflow/W&B). Safety & governance:

Implement guardrails (prompt injection/PII/toxicity), policy filters (Bedrock Guardrails/Azure AI Content Safety/OpenAI Moderation), access controls, and compliance logging. Data & pipelines:

Build/maintain data ingestion, cleansing, and labeling workflows for model/retrieval corpora; ensure schema/version governance. Performance & cost:

Optimize with batching, streaming, JSON-schema/function calling, tool-use, speculative decoding/KV caching, and token budgets. Collaboration & mentoring:

Partner with product/engineering/DS; review designs/PRs, mentor juniors, and drive best practices/playbooks. Preferred Qualifications

Agent ecosystems:

Deeper experience with multi-agent planning/execution, tool catalogs, and failure-mode design. Search & data stores:

Experience with pgvector/Elasticsearch/OpenSearch; comfort with relational/NoSQL/graph stores. Advanced evals:

Human-in-the-loop pipelines, golden sets, regression suites, and cost/quality dashboards. Open-source & thought leadership:

OSS contributions, publications, talks, or a strong portfolio demonstrating GenAI craftsmanship. Nice to Have

Eventing & rate limiting:

Redis/Celery, task queues, and concurrency controls for bursty LLM traffic. Enterprise integrations:

Experience with API gateways (e.g., MuleSoft), authN/Z, and vendor compliance reviews. Domain experience:

Prior work in data-heavy or regulated domains (finance/health/gov) with auditable GenAI outputs.

Requirements

Experience:

6+ years across Data/ML/GenAI, with

1-2+ years

designing and shipping LLM or GenAI apps to production. Languages & APIs:

Strong Python and FastAPI; proven experience building secure, reliable REST services and integrations. Models & frameworks:

Hands-on with OpenAI/Anthropic/Gemini/Llama families and at least two of:

AutoGen, LangGraph, CrewAI, LangChain, LlamaIndex, Transformers . RAG & retrieval:

Practical experience implementing vector search and reranking, plus offline/online evals (e.g.,

RAGAS , promptfoo, custom harnesses). Cloud & DevOps:

Docker, Kubernetes (or managed equivalents), and one major cloud (AWS/Azure/GCP); CI/CD and secrets management. Observability:

Familiarity with tracing/metrics tools (e.g.,

Langfuse , LangSmith,

OpenTelemetry ) and setting SLIs/SLOs. Security & governance:

Working knowledge of data privacy, PII handling, content safety, and policy/controls for enterprise deployments. Communication:

Clear technical writing and cross-functional collaboration; ability to translate business goals into architecture and milestones.
