About Us

5 Tool Performance is a technology-enhanced baseball development facility with over 17,000 sq ft of turf, training space, and performance technology. Our mission is to elevate athlete development through data-driven training, biomechanical insights, and modern software tools.

We are developing an internal Athlete Management System (AMS) that will transform how we track training sessions, player assessments, performance metrics, injury history, and long-term athlete development trends.

To support the buildout, we’re seeking a part-time Software Engineer with genuine interest in both technology and sports performance.

Role Overview

You will collaborate with our leadership and coaching staff to design and build foundational components of our athlete management system. This includes backend features, database schemas, analytics tooling, workflow automation, and clean internal dashboards.

Because much of our methodology is proprietary, an NDA is required before discussing system details.

What You’ll Do

• Build core components of the Athlete Management System (backend, workflows, tooling)
• Create clean, scalable backend logic and well-structured data models
• Integrate modules for training sessions, lessons, assessments, and injury tracking
• Assist with data organization and internal reporting dashboards
• Translate coaching workflows into technical requirements
• Maintain documentation and assist with system architecture decisions
• Help identify patterns or growth opportunities through collected performance data
• Work roughly 9 hours per week with flexibility

What We’re Looking For

Required:

• Strong understanding of software engineering fundamentals
• Experience with modern web development (Node, TypeScript, Python, or similar)
• Experience working with relational databases (PostgreSQL, MySQL, etc.)
• Ability to build APIs and backend systems
• Interest in sports performance—baseball experience is a strong plus
• Clear communication skills with both technical and non-technical staff
• Reliability and strong attention to detail
• Comfort working with sensitive/confidential information

Nice to Have:

• Experience with athlete tracking systems or sports analytics
• Understanding of baseball statistics, biomechanics, or player development
• Familiarity with MVC patterns, REST APIs, or GraphQL
• Data visualization or dashboard experience
• Knowledge of cloud hosting (AWS, Azure, Vercel, etc.)
• Experience building internal tools or productized systems

Why Join Us

• Be an early engineer shaping a system used daily in player development
• Work closely with coaches and performance staff to solve real problems
• Grow your skills in sports tech, data systems, and software design
• Collaborate within a culture focused on learning and continuous improvement
• Opportunity to transition into a more full-time role after 3 months
• Support a larger mission we’ll share after NDA signing

How to Apply

• Your resume or GitHub portfolio
• A brief statement on why you're interested in sports tech and athlete development
• Any relevant project links or tools you've built
