These environments power internal dogfooding, UX validation, and customer demos, reducing reliance on ad-hoc local setups and enabling scalable, repeatable and delightful product experiences.

Today, engineers are frequently pulled into demo setup and environment management of the suite of products, creating context switching and slowing product delivery.  This role exists to solve that problem by establishing reliable, self-service environments and tighter system integration, allowing engineering teams to focus on building product capabilities while improving overall product quality and usability.

You will operate at the intersection of platform engineering and product development, ensuring that the systems we build can be continuously exercised, validated, and experienced in real-world conditions. You will be responsible for advocating for a delightful customer product experience as the integrator of the product portfolio.

What You'll Work On: 

• Designing and operating always-on product environments for customer demos, internal use, and stakeholder access

• Building feature branch / preview environments to support UX and rapid feedback loops

• Enabling internal dogfooding through real, long-running deployments of UDS products

• Integrating core system components across Fleet Management, Edge Management, OS, and related services

• Reducing reliance on local environments by creating shared, reproducible infrastructure

• Supporting pathways toward self-service demo and trial environmentsImproving system reliability by enabling continuous, real-world usage and validationPartnering with engineering, product, and UX to ensure environments reflect real user scenarios

Responsibilities: 

• Design, build, and maintain scalable platform environments that support development, testing, and demos

• Own the reliability and usability of shared environments used across the team

• Collaborate closely with software engineers to integrate platform and product components

• Identify and close gaps in system integration across services and infrastructure layers

• Build and maintain infrastructure as code for reproducible environments

• Improve developer experience by reducing friction in environment setup and usage

• Support product implementation and stakeholder access through stable, well-understood systems

• Contribute to platform and product architecture decisions where environments and integration are concerned
