Colorado Rockies•Denver, CO

8d•$140,000 - $170,000•Onsite

About The Position

This is an exciting time to join the Colorado Rockies as we continue to evolve how technology, data, and baseball expertise come together across Baseball Operations. Baseball Systems is helping build the tools and infrastructure that will support the organization’s next chapter, turning data, scouting insights, and organizational knowledge into intuitive applications that help our people evaluate talent, develop players, identify opportunities, and make informed baseball decisions. As a Senior Full Stack Developer, you won’t simply maintain existing systems, you’ll have the opportunity to help shape what comes next. You’ll design and build the internal web applications that serve scouting, player development, player acquisition, and research, owning features end to end, from data access and backend services through to the interfaces our staff rely on every day. You’ll work directly with scouts, analysts, developers, and Baseball Operations leaders to solve meaningful problems, modernize how information is used across the organization, and build technology that can have a lasting impact on how we make baseball decisions. In addition to hands-on development responsibilities, the Senior Full Stack Developer will provide technical leadership by shaping architecture and design decisions, establishing engineering best practices, improving system reliability, and mentoring other engineers. This is an individual-contributor role with meaningful technical leadership and mentorship scope, not a people-management position.

Requirements

Five or more years of software development experience, or an equivalent combination of experience and demonstrated capability.
Significant experience building and maintaining production web applications across the full stack, including both backend services and user-facing interfaces.
Strong proficiency in a typed language such as TypeScript, with solid command of a modern component-based front-end framework (such as Svelte, React, or Vue) and core front-end fundamentals including HTML and CSS.
Experience designing and building backend services and APIs.
Advanced SQL and experience working with relational databases and modern ORMs.
Experience designing scalable, maintainable application architecture and evaluating technical tradeoffs.
Hands-on experience with a major cloud platform, such as AWS, Azure, or GCP.
Experience with automated testing across the stack, including unit and end-to-end tests.
Demonstrated ability to provide technical leadership through architecture and design decisions, code reviews, engineering standards, and mentorship.
Strong communication and collaboration with both technical and non-technical stakeholders.
