About the Role
We are looking for a hands-on Machine Learning Engineer III to build and run the ML and AI systems behind our agents for content, media, and sales. You will work closely with Data Science, Engineering, Platform, Product, and Operations teams to take models and LLM-based agents from idea to production, and keep them reliable, fast, and cost-efficient at scale. This is an engineering role first: you will own your systems end to end, including the infrastructure they run on. We look for builders who ship v0s quickly, iterate against evals, and stay adaptable about models and frameworks as the field moves.
Key Responsibilities :
AI Agents & Harnesses: Design, build, and ship production agents and the harnesses around them: tool and action design, context window management (retrieval, summarization, compaction), model selection and routing, memory and state, and subagent and parallel tool-call patterns. Iterate until agents reliably complete real customer tasks.
ML Pipelines: Build end-to-end batch and real-time pipelines for classical ML and LLM workloads, from data ingestion to deployment.
Infrastructure: Own the infrastructure your systems run on: containers, Kubernetes, queues, caches, and cloud services on AWS/GCP, managed as code.
Reliability & Quality: Meet latency, throughput, and cost budgets using caching, batching, and parallel execution. Handle rate limits, retries, and failures gracefully. Instrument agents with tracing to profile behavior, find bottlenecks, and catch quality regressions before customers do.
Evals: Build eval sets from production traces, expert examples, and past failures, plus automated checks and LLM judges that measure model and agent quality. Use them to gate every prompt, model, and code change.
Feedback & Experimentation: Turn reviewer and customer feedback into measurable improvements through human-in-the-loop workflows, A/B tests, offline replays, and staged rollouts.
Technical Ownership: Review designs and code, raise the engineering bar, and contribute to the ML and AI roadmap with Data Science and Platform teams.
5+ years of experience building and running ML or AI systems in production, including at least 1 year on LLM-based applications. Bachelor's or Master's in Computer Science, Maths/Stats, or a related field, or equivalent practical experience.
Strong programming skills in Python, including async and concurrent programming, and solid SQL.
Hands-on experience building production agents and LLM applications: tool and function design, context window management, RAG and embeddings, structured outputs, multi-step and multi-agent orchestration, and model selection across hosted APIs (OpenAI, Anthropic, Gemini, or similar).
Daily use of coding agents such as Claude Code or Cursor, with the judgment to review and verify their output.
Solid ML fundamentals (evaluation metrics, overfitting, leakage, drift) and experience deploying models in both batch and real-time setups, including knowing when classical ML beats an LLM.
Strong infrastructure skills: Docker, Kubernetes, at least one cloud provider (AWS / GCP / Azure), and production observability (OpenTelemetry, Grafana, Prometheus, or equivalent).
Working experience with Terraform and CI/CD, distributed data processing (Spark or Databricks), and workflow orchestration or messaging (Airflow, Temporal, Kafka, or similar).
Strong system design skills. You can reason clearly about cost, latency, failure modes, and scale trade-offs.
Excellent written and verbal communication, and the ability to drive cross-functional requirements with Product and Engineering.
Advanced evals: LLM-as-judge calibration against human labels, golden datasets, trace capture and replay, and statistically sound comparisons of variants with confidence intervals.
Agent frameworks & protocols: Hands-on with LangGraph, the OpenAI Agents SDK, MCP, or similar, and knowing when a thin custom harness beats a framework.
Simulation environments: Simulated users and synthetic tasks for testing multi-step agents before they reach customers.
LLM observability & prompt management: Tools like LangSmith, Opik, or Langfuse for tracing, versioning, and debugging prompts in production.
Cost & latency tuning: Prompt caching, batching, model routing, and output-length control for high-volume LLM workloads.
Guardrails: Schema validation, content and safety checks, and fallbacks for when the model gets it wrong.
Vector search: Databricks Vector Search, pgvector, OpenSearch, or similar.
Fine-tuning: Adapting models (SFT, LoRA/PEFT, preference tuning, distillation) and serving them efficiently, including on GPUs (vLLM, TGI, or equivalent).
Research: A track record of turning research into production impact. Publications or open-source contributions are a plus.
Experience in ecommerce, retail media, or B2B SaaS.
Your work ships. Our AI agents run inside the workflows of the world's largest brands every week, and you will see the impact directly.
Work across classical ML, LLMs, agents, and infrastructure, not one narrow slice.
You will own projects end to end, from exploration to production.
Forget endless meetings. Get things done and start making an impact from day 1.
We are an equal opportunity employer and value diversity at our company. We do not discriminate on the basis of race, religion, color, national origin, gender, sexual orientation, age, marital status, veteran status, disability status or any other category prohibited by applicable law.
