Principal Platform Engineer

The Principal Platform Engineer will serve as a hands-on technical leader responsible for designing, building, and evolving Drug Free Sport International’s next-generation global integrity platform. This role is ideal for a senior engineer and platform architect who thrives at the intersection of system architecture, full-stack engineering, data strategy, and technical leadership. You will play a critical role in modernizing and connecting multiple systems into a unified, scalable platform that supports mission-critical, high-trust, and globally impactful work.

As a Principal-level individual contributor, you will define technical architecture, establish engineering standards, guide integration strategy, and actively write production code. You will partner closely with Product, IT, Operations, and external development teams to shape both the technical foundation and long-term platform vision of the organization. This is not a purely advisory or management role. The Principal Platform Engineer is a builder, architect, and technical leader who enjoys solving complex engineering problems while remaining hands-on in development and delivery.

We are building a next-generation Global Integrity Platform designed to modernize and unify critical operational systems across the organization. This is a rare opportunity to shape the architecture, engineering practices, and platform strategy of a growing global organization while remaining deeply hands-on in building the future platform itself.

What You Will Do:

Architecture & Platform Design

• Define and own the end-to-end architecture for a multi-system, evolving platform ecosystem.
• Lead architecture decisions across backend systems, integrations, infrastructure, and data platforms.
• Design core data models and integration patterns shared across systems and business domains.
• Establish API-first architecture, service boundaries, and interoperability standards.
• Lead foundational data architecture, including data modeling, warehouse strategy, and operational reporting enablement.
• Design for scalability, multi-tenancy, security, compliance, and long-term extensibility from the start.
• Drive technical decision-making through architecture documentation, standards, and collaborative reviews.

Full-Stack Engineering (Hands-On)

• Write and deliver production-grade software across backend services, APIs, integrations, and frontend applications.
• Build and evolve platform capabilities used across multiple teams and operational domains.
• Develop data pipelines and integration layers that connect existing and future systems.
• Contribute to UX/UI decisions to ensure intuitive and scalable user experiences.
• Improve platform reliability, maintainability, observability, and performance.
• Own the integration surface across operational tools and help normalize workflows and data structures across legacy systems.
• Establish engineering standards, best practices, and development patterns .

Technical Leadership & Collaboration

• Serve as a senior technical authority across multiple systems and initiatives.
• Partner with Product, IT, Operations, and business stakeholders to align technical solutions with organizational goals.
• Translate complex technical concepts into clear, actionable guidance for technical and non-technical stakeholders.
• Evaluate emerging technologies, frameworks, and AI-assisted development capabilities.
• Collaborate with external vendors and development partners, including reviewing deliverables and defining technical acceptance criteria.
