Software Development Engineer I

The Opportunity

* This position is based out of our Greenwood Village, Colorado office and requires regular, in-person attendance.

Ulteig is looking for a Software Engineer who is a Computer Science graduate seeking their first professional software engineering role and who is excited to build with modern AI technologies.

This position is within Digital Transformation; Ulteig defines digital transformation as:

The deliberate use of digital technologies to modify or create business processes, customer experiences, and enable organizational culture in response to or anticipation of changes in the market, customer insights, and business needs.

This role is ideal for graduates who are AI builders-engineers who actively leverage AI tools such as agents, large language models, and modern AI frameworks to create software, while also understanding the core computer science principles, patterns, and practices that make solutions reliable, scalable, and safe.

You will work closely with experienced software engineers and AI leaders, learning how to translate real business problems into AI-enabled solutions, contributing code, prototypes, and experiments while growing your technical depth and professional confidence.

What You’ll Do

Hands-On Development & Learning

• Contribute to the design, development, and testing of AI-enabled software solutions under the guidance of senior engineers.
• Write production-quality code using languages and technologies such as C#, Python, React, APIs, and modern AI tooling.
• Build and enhance features that incorporate AI capabilities such as large language models, agents, vision, and automation.
• Assist with prototypes and proofs-of-concept to explore new use cases and validate feasibility.
• Learn how to apply software engineering fundamentals-readability, testability, performance, and maintainability-even when using AI-assisted development tools.

AI Builder Mindset

• Leverage AI coding assistants and techniques to accelerate development while understanding why the generated code works.
• Apply emerging AI patterns (such as prompt design, retrieval, and tool-use concepts) in practical, supervised settings.
• Learn when AI is the right tool-and when traditional software patterns are more appropriate.
• Develop an ethical, secure, and responsible approach to using AI in real business workflows.

Collaboration & Growth

• Collaborate with software engineers, product partners, and business stakeholders in a team-based environment.
• Participate in code reviews, design discussions, and sprint ceremonies.
• Ask thoughtful questions, seek feedback, and continuously improve your technical skills.
• Engage in training, workshops, and learning opportunities focused on AI, cloud, and modern software development.

What We Expect from You

Education & Early Experience

• Bachelor’s degree in computer science, software engineering, or a closely related field.
• This role is intended for new or recent graduates (internships, co-ops, academic projects, or personal projects are great).
• Demonstrated interest in AI and modern software development through coursework, projects, hackathons, research, or self-directed learning.

Technical Foundations

• Working knowledge of at least one programming language, such as C#, Python, Java, or similar.
• Solid understanding of core computer science concepts, including:
• Data structures and data handling
• APIs and basic system design
• Basic design patterns
• Introductory exposure to AI / Machine Learning or Generative AI concepts is strongly preferred (academic or hands-on).
• Familiarity with using AI tools (copilots, chat-based assistants, etc.) for coding or problem-solving is a requirement.

Mindset & Potential

• Strong curiosity and enthusiasm for building, experimenting, and learning.
• Comfortable using AI to accelerate work while valuing engineering fundamentals and good design.
• Growth mindset with openness to coaching, feedback, and continuous improvement.
• Responsible and thoughtful approach to using AI technologies.
• Motivated self-starter who takes ownership of learning and assigned work.
• Demonstrates openness to innovation by embracing and applying evolving technology and AI tools to enhance workflows, solve problems, and drive continuous improvement.
• Must have authorization to work permanently in the U.S.

Why This Role

This role is intentionally designed as a launchpad. You won’t be expected to be an AI expert on day one. Instead, you’ll be supported through:

• Mentorship from experienced software and AI engineers
• Structured learning and hands-on exposure to real use cases
• Increasing responsibility as your skills and confidence grow
• Successful candidates will grow into more advanced software engineering roles, contributing to the evolution of Ulteig’s capabilities while building a strong foundation for a long-term engineering career.
