Internship Full Stack Machine Learning Engineer Jobs in Rocklin, CA

About CREtelligent 

CREtelligent builds the SaaS platform that powers commercial real estate environmental due diligence — turning property, parcel, and risk data into the reports and workflows lenders, investors, and consultants rely on. Our engineering team is small, hands-on, and collaborative, and we're growing. You'll have real ownership across the stack and a direct line to the decisions that shape the product. 

About the Role 

We're looking for an experienced full stack engineer to build and maintain features across our Spring Boot microservices and our Angular and React frontends. This is a build-and-own role: you'll work the full lifecycle — design, implementation, code review, testing, and production support — alongside a team that values thoughtful, deliberate engineering over shipping fast and hoping for the best. 

How We Work 

We're an AI-forward team. AI coding assistants — Claude Code, Copilot, and friends — are part of our everyday toolkit. We lean into "vibe coding" to move fast on the first 80%, then bring engineering judgment to the part that actually matters: reviewing the output, writing the tests, and proving it's correct before it ships. We want engineers who are fluent with these tools and know when not to trust them. AI accelerates the work; it doesn't replace the thinking. 

What You’ll Do 

• Design, build, and maintain backend services in Java 17 / Spring Boot 3.x, including REST APIs and integrations with internal and third-party systems (Salesforce, QuickBooks, AWS, and others). 

• Develop and improve frontend features in Angular and React (TypeScript) with Redux, Vite, and MUI — from data layer through UI, including interactive map / geospatial views (Deck.gl). 

• Model and work with data in MongoDB, balancing query performance, schema design, and data quality. 

• Participate in architecture discussions and contribute to platform evolution, including our ongoing move toward an API-led integration architecture. 

• Write clean, well-tested code and take part in thorough, adversarial code reviews — finding the bug before it ships, not after. 

• Collaborate with QA, product, and fellow engineers to scope work, isolate clean PRs, and own quality through to release. 

• Troubleshoot production issues with a hypothesis-driven, read-the-data-first approach. 

Who We’re Looking For 

• 5+ years of professional software engineering experience. 

• 5+ years experience with JavaScript, Java, NoSQL databases. 

• Proven experience in full stack software engineering. 

• Strong backend skills in Java, with hands-on Spring Boot experience. 

• Proficiency with JavaScript / TypeScript and modern frontend development. 

• Production experience with both Angular and React (or deep experience in one and genuine willingness to work in the other), plus familiarity with Redux-style state management and modern build tooling (Vite). 

• Working knowledge of MongoDB or comparable NoSQL databases — schema design, aggregation, indexing. 

• Solid grasp of REST API design, authentication / authorization patterns (JWT / OAuth2), and service-to-service integration. 

• Comfort with Git-based workflows and CI/CD. 

• Fluency with AI-assisted development workflows (Claude Code, Copilot, or similar) — paired with a review-everything skepticism about what they generate. 

• Clear written and verbal communication, and the judgment to know when to ask versus when to dig in. 

Nice to Have 

• Experience with AWS (S3 in particular) and cloud-native service deployment. 

• Exposure to microservices migration or modernization efforts (e.g., consolidating legacy services, integration platforms like MuleSoft). 

• Familiarity with geospatial / mapping work — Deck.gl, Google Maps APIs, parcel / GIS data, or similar. 

• Salesforce integration experience. 

• Background in real estate, environmental, insurance, or other data-heavy regulated domains. 

• SOC 2 or other compliance-aware development experience.
