Annotation Engineer Jobs (NOW HIRING)

Rivian is on a mission to keep the world adventurous forever. This goes for the emissions-free Electric Adventure Vehicles we build, and the curious, courageous souls we seek to attract. 

As a company, we constantly challenge what’s possible, never simply accepting what has always been done. We reframe old problems, seek new solutions and operate comfortably in areas that are unknown. Our backgrounds are diverse, but our team shares a love of the outdoors and a desire to protect it for future generations. 

Rivian’s Autonomy organization is looking for a Staff Software Engineer, ML Applications on the Data & Cloud team. You will set the direction for large-scale applications and data pipelines that power data annotation, ML/DL training and infrastructure, using modern cloud services and open-source frameworks. You will tackle ambiguous, cross-functional problems (scale, reliability, cost, developer velocity) and align engineering, ML, and data partners on architecture and roadmaps. You will help the Autonomy organization move faster by building reliable, observable software on top of petabyte-scale sensor datasets.

• Lead the technical development of Rivian’s in-house 2D and 3D labelling platform, enabling the delivery of high quality data for model training and validation.
• Set full-stack platform direction (TypeScript, React) for internal tools that accelerate annotation and ML workflows.
• Lead alignment on backend services and APIs (Go/Python) across teams; establish standards for APIs, data contracts, and service boundaries.
• Guide data modeling and storage strategy across NoSQL databases like MongoDB, including performance, cost and consistency tradeoffs at scale.
• Partner with architects, ML engineers, and data engineers on requirements, architecture and design.
• Drive cloud cost, performance, and reliability initiatives; champion SLOs, observability, and incident learning.
• Mentor junior engineers with technical leadership and knowledge.

• B.S., M.S., or Ph.D. in Computer Science or a related field and at least 6 years of relevant experience; or at least 8 years of industry experience without a degree.
• Strong full-stack background with TypeScript and modern web stacks (React preferred); track record shipping and evolving complex internal web applications.
• Deep backend expertise in Python, Go, or Java on high-throughput or large-data systems. 
• Demonstrated success leading technical design for multi-service or platform-scale systems. 
• Hands-on experience with MongoDB, Postgres, and/or similar databases in production. 
• Proven ability to work cross-functionally across teams and domains, and to communicate clearly to technical and non-technical leaders. 
• History of mentoring engineers and improving team-wide engineering practices. 

Preferred Qualifications 

• Familiarity with end-to-end ML workflows and the production lifecycle of ML data (ingestion, labeling, training, evaluation). 
• Experience with AWS, MLOps, and data/ML pipelines in cloud environments.
