About The Role

At PicCollage, our Machine Learning, Algorithms & Data (MLAD) team thrives on solving complex challenges with elegance and scale. As a Backend Engineer (ML Platform), you’ll be at the heart of this—designing and building robust platforms and pipelines that make it seamless to develop, deploy, and monitor ML models used by millions worldwide.

You’ll collaborate closely with a team of like-minded experts who love sharing their deep domain knowledge, working together to bring cutting-edge AI research into real-world products. With a culture that champions continuous learning (yes, we sponsor trips to world-renowned conferences like CVPR), you’ll grow as you help deliver high-impact innovations—fast, reliable, and at scale.You will work closely with ML engineers, backend teams, and product teams to bring cutting-edge AI research into real-world products and ensure that models are reliably integrated and operate efficiently in production.

This role is sometimes known as MLOps Engineer in other organizations, but we use Backend Engineer (ML Platform) to emphasize strong backend development and infrastructure skills.

What You'll Do

• Design, implement and maintain machine learning platform and data pipelines, ensuring seamless deployment, scaling, and monitoring of models in production environments.
• Set up monitoring systems for deployed models and tracking key metrics.
• Apply and share software engineering best practices within the context of machine learning.
• Collaborate with ML engineers to ensure model performance is maintained in production and work with software engineers to integrate ML systems into the broader application stack.
• Accelerate machine learning development, evaluation, and integration speed through automation of workflows, tools, and processes to enhance collaboration and efficiency.

What We’re Looking For

• Proficiency in Python, with solid software engineering fundamentals.
• Hands-on experience designing and building backend APIs or services with frameworks like FastAPI, Django, or similar.
• Experience building and operating containerized applications using Docker, with hands-on expertise in managing Kubernetes clusters.

Nice-To-Haves

• Experience with cloud platforms such as GCP, AWS, or Azure.
• Experience with machine learning frameworks (PyTorch, TensorFlow).
• Experience with MLOps tools (Kubeflow, MLflow, TFX).
• Experience with monitoring tools (Prometheus, Grafana) and logging frameworks.
• Knowledge of data engineering concepts (ETL pipelines, data lakes, data warehouses).
• Understand and apply AI tools into your workflow.

There are three main stages in our interview process:

1. Screen calls (1-2 calls)
2. Take-home quiz & review
3. Onsite interview (3-4 hours visiting)
   

If we see a fit with the company, we will reach out to start getting to know each other. You can expect traditional discussions as well as participating in situational exercises. The goal of the interview process will be for us to see your skills and let you get to know the team and work culture to see if we are a match.
