Company mission
To enable brands to build repeatable and scalable programs that accelerate business growth, efficiently, and effectively, and drive higher ROI on their marketing investments.
Role
Who you are
- You’ll thrive here if you…
- Think “impact > model elegance.” You pick the simplest approach that moves the KPI
- Prototype loudly. You’d rather show a working demo than a 40page deck
- Stay humble. If a spreadsheet baseline wins, you celebrate—and then raise the bar
- Translate effortlessly. You can chat GPU kernels at noon and revenue funnels at 12:05
- Love ambiguity. Blank whiteboards signal possibility, not paralysis
Desirable
- End to end ML product ownership—from prototype notebook to cloud native service
- Fluency in Python with libraries such as scikitlearn, PyTorch, TensorFlow, XGBoost, LightGBM
- Experience choosing and finetuning foundation/LLM or diffusion models when they’re the quickest path to value
- Comfort with feature stores, vector databases, and MLOps stacks (Airflow/Prefect, MLflow, Kubeflow, SageMaker, Vertex, or equivalents)
- Both batch and low latency serving patterns (REST, gRPC, or streaming)
- SQL that hunts for signal in messy data and A/B results
- Solid grounding in statistics and experimental design, plus the storytelling chops to explain lift to non-data partners
- Version control, CI/CD, and a bias toward shipping thin vertical slices over monoliths
What the job involves
- We’re a small band of business savvy technologists who treat machine learning as a means, not an end. Our charter: find revenue shaping opportunities, ship the first working model or service in days or weeks, watch how the market reacts, then double down—or pivot—fast. Ego takes a back seat to curiosity, and “good enough for now” often beats “perfect but late.”
- Frame & focus. Translate fuzzy growth ideas into moldeable problems, pick the metrics that matter, and design bite-sized experiments to learn quickly
- Build fast, in or out of the box. Finetune a foundation model when it’s the 80percent solution; spin up a from scratch architecture only when the use case truly needs it
- Own the full lifecycle. Prototype in notebooks, productionize via Python APIs or lightweight microservices, and wire up offline scoring, real-time inference, and monitoring
- Make it self-serve. Wrap models in simple endpoints, SDKs, or SQL functions so analysts and engineers can self select the magic without a helpdesk ticket
- Instrument & iterate. Track performance drift, cost, and business lift; retrain or retire ruthlessly based on evidence
- Teach the village. Run demos, share code snippets, and mentor teammates on pragmatic ML patterns that survive first contact with customers
- Why join Zeta’s Data Cloud Acceleration team
- Velocity. Your models meet customers in weeks, not quarters
- Tool freedom. Choose the stack that fits the problem—no six month procurement saga
- Breadth. Projects jump from ad-tech optimization to identity resolution to GenAIpowered personalization
