About the role
ML Ops Engineer — Agentic AI Lab (Founding Team)
Location: San Francisco Bay Area
Type: Full-Time
Compensation: Competitive salary + meaningful equity (founding tier)
Backed by 8VC, we're building a world-class team to tackle one of the industry’s most critical infrastructure problems.
About THE Role
Our AI Lab is pioneering the future of intelligent infrastructure through open-source LLMs, agent-native pipelines, retrieval-augmented generation (RAG), and knowledge-graph-grounded models.
We’re hiring an ML Ops Engineer to be the glue between ML research and production systems — responsible for automating the model training, deployment, versioning, and observability pipelines that power our agents and AI data fabric.
You’ll work across compute orchestration, GPU infrastructure, fine-tuned model lifecycle management, model governance, and security e
Responsibilities
-
Build and maintain secure, scalable, and automated pipelines for:
-
LLM fine-tuning, SFT, LoRA, RLHF, DPO training
-
RAG embedding pipelines with dynamic updates
-
Model conversion, quantization, and inference rollout
-
Manage hybrid compute infrastructure (cloud, on-prem, GPU clusters) for training and
-
inference workloads using Kubernetes, Ray, and Terraform
-
Containerize models and agents using Docker, with reproducible builds and CI/CD via
-
GitHub Actions or ArgoCD
-
Implement and enforce model governance: versioning, metadata, lineage, reproducibility,
-
and evaluation capture
-
Create and manage evaluation and benchmarking frameworks (e.g. OpenLLM-Evals,
-
RAGAS, LangSmith)
-
Integrate with security and access control layers (OPA, ABAC, Keycloak) to enforce
-
model policies per tenant
-
Instrument observability for model latency, token usage, performance metrics, error
-
tracing, and drift detection
-
Support deployment of agentic apps with LangGraph, LangChain, and custom inference
-
backends (e.g. vLLM, TGI, Triton)
-
DESIRED EXPERIENCE
-
Model Infrastructure:
-
4+ years in MLOps, ML platform engineering, or infra-focused ML roles
-
Deep familiarity with model lifecycle management tools: MLflow, Weights & Biases, DVC,
-
HuggingFace Hub
-
Experience with large model deployments (open-source LLMs preferred): LLaMA,
-
Mistral, Falcon, Mixtral
-
Comfortable with tuning libraries (HuggingFace Trainer, DeepSpeed, FSDP, QLoRA)
-
Familiarity with inference serving: vLLM, TGI, Ray Serve, Triton Inference Server
-
Automation + Infra:
-
Proficient with Terraform, Helm, K8s, and container orchestration
-
Experience with CI/CD for ML (e.g. GitHub Actions + model checkpoints)
-
Managed hybrid workloads across GPU cloud (Lambda, Modal, HuggingFace Inference,
-
Sagemaker)
-
Familiar with cost optimization (spot instance scaling, batch prioritization, model sharding)
-
Agent + Data Pipeline Support:●
-
Familiarity with LangChain, LangGraph, LlamaIndex or similar RAG/agent orchestration tools
-
Built embedding pipelines for multi-source documents (PDF, JSON, CSV, HTML)
-
Integrated with vector databases (Weaviate, Qdrant, FAISS, Chroma)
-
Security & Governance:
-
Implemented model-level RBAC, usage tracking, audit trails
-
Integrated with API rate limits, tenant billing, and SLA observability
-
Experience with policy-as-code systems (OPA, Rego) and access layers
-
Preferred Stack
-
LLM Ops: HuggingFace, DeepSpeed, MLflow, Weights & Biases, DVC
-
Infra: Kubernetes (GKE/EKS), Ray, Terraform, Helm, GitHub Actions, ArgoCD
-
Serving: vLLM, TGI, Triton, Ray Serve
-
Pipelines: Prefect, Airflow, Dagster
-
Monitoring: Prometheus, Grafana, OpenTelemetry, LangSmith
-
Security: OPA (Rego), Keycloak, Vault
-
Languages: Python (primary), Bash, optionally Rust or Go for tooling
-
Mindset & Culture Fit
-
Builder's mindset with startup autonomy: you automate what slows you down
-
Obsessive about reproducibility, observability, and traceability
-
Comfortable with a hybrid team of AI researchers, DevOps, and backend engineers
-
Interested in aligning ML systems to product delivery, not just papers
-
Bonus: experience with SOC2, HIPAA, or GovCloud-grade model operations
What We’re Looking FOR
-
Experience:
-
5+ years as a full stack or backend engineer
-
Experience owning and delivering production systems end-to-end
-
Prior experience with modern frontend frameworks (React, Next.js)
-
Familiarity with building APIs, databases, cloud infrastructure, or deployment workflows at scale
-
Comfortable working in early-stage startups or autonomous roles, prior experience as a founder, founding engineer, or a 0-1 pre-seed startup is a big plus
-
Mindset:
-
Comfortable with ambiguity, eager to prototype and iterate quickly
-
Strong sense of ownership — prefers to build systems rather than wait for tickets
-
Enjoys thinking about architecture, performance, and tradeoffs at every level
-
Clear communicator and pragmatic team player
-
Values equity and impact over prestige or hierarchy
-
Prior startup or founding team experience
-
WHY THIS ROLE MATTERS
-
Your work will enable models and agents to be trained, evaluated, deployed, and governed at
-
scale — across many tenants, models, and tasks. This is the backbone of a secure, reliable,
-
and scalable AI-native enterprise system. If you dream about using AI to solve some really hard
-
real world problems – we would love to hear from you.
