Backend Developer - Firebase

Back-End Developer – Firebase & Cloud Infrastructure Location: Remote (US required) Employment Type: Part-Time / Contract (with growth potential) Reports To: Founder About Us Athlete Rating System (ARS) is a performance-focused sports analytics platform built to help athletes, coaches, and evaluators measure development in a structured and objective way. ARS is live today and evolving toward monetized features. Role Overview ARS is seeking a Back-End Developer with strong Firebase expertise to own and evolve the server-side infrastructure powering the ARS platform. This role focuses on designing, building, and maintaining scalable, secure backend systems that support real-time data, authentication, cloud functions, and storage across multiple platforms. You will work directly with the ARS founder and the front-end developer to shape core backend architecture, data models, and application logic. This position is ideal for someone who already has a primary role but can commit focused development time each week and take meaningful ownership of backend decisions. Success in this role requires a founder’s mindset—comfort with ambiguity, pragmatic problem-solving, and accountability for long-term technical direction rather than task-based execution alone. This position offers a path toward becoming a technical co-founder. As the platform grows and monetization milestones are reached, the developer in this role may earn an equity interest based on measurable contribution and long-term commitment. Equity consideration is milestone-driven and structured to align incentives while protecting the company’s long-term flexibility. Duties • Develop and optimize backend services using Firebase tools including Firestore, Realtime Database, Cloud Functions, Authentication, and Storage. • Collaborate with front-end developers to integrate UI components with server-side logic using React, Angular, or other frameworks. • Design and implement RESTful APIs and web services to facilitate smooth data exchange between client applications and backend systems. • Ensure application security by implementing authentication protocols, data validation, and access controls within Firebase. • Write clean, efficient code adhering to best practices in software development and SDLC (Software Development Life Cycle). • Conduct unit testing and debugging to identify issues early and ensure high-quality deliverables. • Participate in Agile development processes, including sprint planning, stand-ups, and code reviews to foster continuous improvement. Qualifications • 3+ years of backend development experience. • 2+ years of hands-on Firebase experience. • Proven experience in web development with a strong focus on backend systems using Firebase platform components. • Proficiency in JavaScript, TypeScript, Node.js, and related frameworks such as React Express or Angular. • Solid understanding of database design principles with experience in Firebase Firestore, MySQL, PostgreSQL or MongoDB. • Knowledge of RESTful APIs, SOAP web services, JSON/XML data formats, and microservices architecture. • Familiarity with version control systems like GitHub for automated deployment processes. • Experience working within an Agile environment and utilizing tools for project management. • Strong debugging skills with the ability to troubleshoot complex issues efficiently across various platforms. • Understanding of application security best practices including OAuth2, JWT tokens, and data encryption techniques. Join us if you’re eager to develop innovative backend solutions that power impactful applications!
