As a Software Engineer II, you will work with a team of engineers to deliver solutions that support how dealers acquire and exit inventory. The team builds applications using C# and Stencil, running on AWS, combining backend services with modern web interfaces to deliver reliable and highly available systems. The role focuses on contributing to the design, development, testing, and deployment of software, with ownership of individual features and components.
You will collaborate closely with engineering, product management, UX, and solution delivery teams to deliver incremental value while maintaining system stability. This includes supporting production systems and participating in on-call rotations, building strong fundamentals in incident response and continuous improvement.
Strong engineering practices are expected, including testing-first development and effective use of AI-assisted development tools. The team follows a spec-driven development approach, where clear, well-defined specifications guide implementation and AI-generated code. This includes working from structured requirements, validating outputs against those specifications, and contributing to software that is reliable, maintainable, and aligned with intended behavior.
This is a hybrid role based in Austin, TX with an in-office requirement.
What You'll Do
- Design and implement APIs, services, and cloud-based solutions within an existing architecture.
- Write readable, maintainable, and efficient code.
- Own delivery of features and components from development through testing and production support.
- Enhance performance and reliability of existing systems.
- Support and operate production systems, including participation in on call rotations.
- Collaborate with team members on code reviews, best practices, and process improvements.
- Participate in breaking down stories into technical tasks and contributing to estimates.
- Build familiarity with the applications, services, and systems supported by the team.
- Apply spec-driven development practices to guide implementation and validate behavior, including the effective use of AI-assisted development tools.
- Work closely with the Agile team to build, deploy, monitor, and manage highly available production systems.
