Job description

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.

Technology We Use

• Development languages/frameworks: C#, JavaScript, Stencil
• Cloud: Amazon: AWS SDK, Elastic Beanstalk, ElastiCache, S3, EC2, SQS, SNS, API Gateway, CloudFormation, and AWS cloud‑native architectures Lambda, ECS Fargate
• DevOps Tools: NewRelic, AWS CodeBuild, Github, Splunk, Terraform
• Databases: PostgreSQL, DynamoDB, Elasticsearch, Oracle, OpenSearch
• Tools & Practices: Agile (Scrum/Kanban), DevOps, CI/CD, TDD
• Special Focus: Claude Code

Who You Are

• 2+ years of professional software development experience.
• Bachelor's degree in Computer Science or related field, and 2 years' experience in a related field. The right candidate could also have a different combination, such as a master's degree and up to 2 years' experience; or 14 years' experience in a related field.
• Strong object‑oriented design and development skills.
• Strong C#/.NET skills, including:
  • Experience building APIs and services
  • Understanding of RESTful design patterns
  • Familiarity with modern web frameworks (e.g., Stencil, Angular, or React)
• Experience contributing to applications across the SDLC, from development through production support.
• Ability to write readable, maintainable, and efficient code following established best practices.
• Familiarity with building and operating applications in a cloud environment such as AWS.
• Experience working from defined requirements or specifications to implement and validate software behavior.
• Strong communication skills with the ability to clearly convey technical concepts and collaborate effectively across engineering, product, and UX teams.
• Applicants must currently be authorized to work in the United States for any employer without current or future sponsorship. No OPT, CPT, STEM/OPT or visa sponsorship now or in future.

Preferred

• Experience building and delivering software in cloud‑based systems (e.g., AWS).
• Familiarity with CI/CD pipelines and automated build and deployment processes.
• Understanding of Agile development methodologies and team‑based delivery.
• Experience with automated testing practices (unit, integration, or end‑to‑end).
• Exposure to AI‑assisted development tools and modern software development workflows.

What We Look For

• Ability to work on multiple projects and be flexible to adapt to changing requirements.
• Ability to turn high‑level requirements into a working system through iterative development.
