Hi there, I'm Raùl, Director of Data at TestGorilla. We’re excited to share more about the Senior Machine Learning Operations Engineer role and our team.

At TestGorilla, we’re on a mission to revolutionize hiring.
We help companies source, screen, and shortlist talent through skills-based hiring—empowering one billion people to land their dream jobs. With 2M+ candidates tested and 400+ science-backed assessments, we’re making hiring smarter, faster, and fairer.

About the role

As our Senior Machine Learning Ops Engineer, you’ll be at the heart of building and scaling the systems that bring our machine learning models to life. You’ll design, deploy, and maintain MLOps pipelines that ensure models run smoothly in production and deliver real value to both our clients and internal teams.

You’ll bring strong expertise in MLOps, including deployment, monitoring, CI/CD, and lifecycle management using tools such as SageMaker or MLflow. You’ll also work hands-on with frameworks like TensorFlow, PyTorch, or scikit-learn, and apply your skills in Python, SQL, and vector databases to support advanced machine learning applications.

By combining your knowledge of infrastructure as code with Terraform or AWS CloudFormation, you’ll ensure our data and ML systems are reliable, secure, and scalable. This role gives you the opportunity to directly shape how we deliver machine learning at scale while working in a collaborative, remote-first team that values innovation and impact.

• Experience with ML frameworks (TensorFlow, PyTorch, scikit-learn)
• Proficiency in Python, SQL, and vector databases
• Experience with infrastructure as code (Terraform, CloudFormation)

We actively seek diversity and encourage applications from everyone. If you're interested in this role but your experience doesn't perfectly match the description, please still apply.
