Champion is an early-stage startup focused on creating deeper partnerships and fostering individual and professional growth. They are seeking a seasoned Principal Engineer to lead the technical vision, architect scalable systems, and mentor engineers while driving the product's growth and technical strategy.
Responsibilities:
- Architect and lead the design of scalable, high-performance systems across our full stack using TypeScript, Node.js, Python, and React
- Drive technical strategy — evaluate tradeoffs, establish patterns, and make foundational decisions that will shape the platform for years to come
- Own complex, ambiguous problems end-to-end, from discovery through delivery, with minimal direction
- Design and build data infrastructure — data pipelines, warehousing solutions, and the data models that power product analytics and customer insights
- Develop and integrate ML-powered features where applicable, including model evaluation, feature engineering, and productionizing models at scale (strong plus)
- Mentor and grow engineers at all levels through code reviews, design discussions, and technical guidance
- Partner cross-functionally with Product and Design to refine roadmap items into well-scoped, high-impact work
- Leverage AI-powered developer tooling (e.g., Claude Code, GitHub Copilot) to accelerate delivery, improve code quality, and set a standard for how the team integrates these tools into everyday workflows
- Champion (pun intended) extensible, secure, and observable software patterns across the organization
