ML Ops Engineer

ML Ops Engineer

Role Overview We’re hiring an ML Ops Engineer to own the reliability, scalability, and operational integrity of our machine-learning systems in research & production. This role sits at the intersection of data engineering and ML infrastructure: you’ll design and operate data pipelines that feed models, and you’ll build the tooling that trains, deploys, monitors, and retrains them.

You’ll work closely with research engineers and product teams, taking models from experimentation to production-grade systems with clear SLAs, reproducibility guarantees, and observable behaviour. This is not a research role; it is a hands-on engineering role focused on making ML systems work reliably t You’ll Work OnML lifecycle infrastructure

Product ionizing models: packaging, deployment, versioning, and rollback

Designing CI/CD pipelines for ML (training validation deployment)
Implementing model monitoring (data drift, prediction drift, performance decay)
Managing experiment tracking and reproducibility

Data engineering foundations

Building and maintaining batch and near–real-time data pipelines

Ensuring data quality, schema evolution, and lineage across systems

Designing datasets and feature pipelines that support both training and inference

Operating pipelines with clear reliability and latency expectations

Operational ownership

Defining and meeting availability, latency, and freshness targets for ML services

Debugging production issues across data, infrastructure, and model layers

Improving system robustness through automation and observability

Collaborating with platform and security teams on access, secrets, and compliance

Engineering rigor

Writing production-grade Python used in long-running services and pipelines

Establishing testing, validation, and release practices for ML systems

Making trade-offs explicit between research flexibility and production stability

Required Qualifications 3–7 years of professional experience in ML Ops, Data Engineering, or adjacent backend roles

Strong production Python skills (clean APIs, testing, performance awareness)
Experience deploying and operating ML models in production environments

Solid understanding of:

Model training vs. inference requirements

Batch vs. streaming data pipelines

Failure modes in data-driven systems

Hands-on experience with at least one modern orchestration or workflow system

Comfort working with cloud infrastructure and containerized workloads

Ability to reason about system design, not just tool usage

Nice-to-Have Experience operating systems at TB-scale data volumes or higher

Prior ownership of model monitoring, drift detection, or automated retraining

Familiarity with feature stores or online/offline feature consistency problems

Experience supporting multiple models or teams on a shared ML platform

Exposure to regulated or high-reliability production environments

Tech Stack (Current & Expected Evolution)

Languages:

Python (core)
ML & Data:
PyTorch / similar frameworks, experiment tracking, structured datasets

Pipelines & Orchestration:
Workflow schedulers for batch and near-real-time processing

Deployment:
Containers, model serving frameworks, infrastructure-as-code Observability:
Metrics, logging, and alerting across data and model layers

Cloud:
Managed compute, storage, and networking (provider-agnostic mindset)
The stack will evolve. We value engineers who understand why systems are built a certain way and can adapt tools as requirements change.

Why This Role Matters Our models only create value when they are correct, observable, and dependable in production. This role is responsible for that reality. You’ll reduce the gap between promising experiments and systems that can be trusted by downstream products and customers.

If you care about data correctness, operational clarity, and building ML systems that don’t silently fail, this role gives you direct leverage over the success of our entire ML platform.
