AI Engineer

Location: Waltham, MA (hybrid- 3 days In-Office)

ERGO NEXT’s mission is to help entrepreneurs thrive. We’re doing that by building the only technology-led, full-stack provider of small business insurance in the industry, taking on the entire value chain and transforming the customer experience. 

Simply put, wherever you find small businesses, you’ll find ERGO NEXT.

Since 2016, we’ve helped hundreds of thousands of small business customers across the United States get fast, customized and affordable coverage. We’re backed by industry leaders in insurance and tech, and we still have room to grow — that’s where you come in.

What You’ll Do

• Design, implement, and optimize backend services that power machine learning-driven features in production environments
• Design and build backend systems that serve machine learning models in production, with a focus on performance, reliability, and scalability
• Ensure model predictions are observable and measurable, enabling evaluation using metrics such as precision, recall, and business impact
• Collaborate with product and cross-functional teams to refine requirements, prioritize high-impact problems, and translate them into clear technical solutions
• Contribute to system design, architecture reviews, and code quality improvements
• Diagnose and resolve complex issues across backend services, data pipelines, and model inference systems, including identifying gaps in model performance and system behavior
• Support innovation and continuous improvement by identifying opportunities and driving technical initiatives

What We Need

• 5+ years of backend engineering experience in Python
• Proven experience building high-performance or distributed systems
• Experience deploying and serving machine learning models in production systems, including building inference pipelines and integrating model outputs into backend services
• Experience evaluating model performance using metrics such as precision, recall, or other business-relevant measures
• Strong understanding of cloud infrastructure, microservices, and observability, including logging and monitoring systems to track model predictions and system performance
• Ability to operate effectively under ambiguity and navigate dynamic environments
• Strong communication and collaboration skills

This role focuses on building and operating production systems that leverage machine learning models. It is not primarily focused on model research, experimentation-only workflows, or prompt engineering.
