Senior Machine Learning Engineer

Who we are

Lopez Cloud is a 17-person software shop in Aurora. The founders still answer support tickets. Customers who call us usually reach someone who wrote the code they are asking about. Most engineers work remotely and come into the office one week a quarter for planning.

Our team is growing and we are hiring a Senior Machine Learning Engineer. We're looking for an engineer to build retrieval-augmented generation features on hosted and open-weight language models, with proper evaluation. ML engineering role focused on pipelines, serving and monitoring. You'll work alongside data scientists rather than replace them. Remote position. Most of the team is in Aurora, but nobody is required to come in. You can set your own hours around a daily morning check-in. Communication happens mostly in Slack and short video calls.

• Build training pipelines in PyTorch or TensorFlow and run them on GPUs in AWS, GCP or Azure
• Handle on-call for the ML services the team owns
• Document model cards, data sources and known failure modes

Minimum qualifications

• 6+ years of software engineering experience, with at least two spent on ML systems in production
