Own technical knowledge across the full stack and infrastructure, retaining architectural context while providing guidance on modern web standards, API design, and event-driven patterns. Be hands-on by writing and owning production-quality code, from GraphQL APIs and streaming consumers to interactive front-ends. Setting a high bar through thoughtful PR reviews and continuously improving reliability and operability. Act as a technical mentor to engineers on full-stack development, cloud-native principles, and best practices for interacting with streaming data platforms like Kafka. Influence the technical direction of product innovation by collaborating with senior leadership, helping to establish well-designed and well-documented cloud architectures, and bringing new concepts from prototype to production.

Your story

5+ years of experience building and operating large-scale, cloud-native applications in production. Extensive hands-on experience with TypeScript, Node.js, and React in a production environment, building both robust back-end systems and responsive, interactive front-ends.

Hands-on experience with Apache Kafka in production, including consuming from and interacting with event streams. Experience leading complex technical initiatives, partnering with multiple stakeholders and teams, and providing technical direction to others. Experience mentoring and coaching engineers, providing guidance and feedback to support their growth and development.

About the Team

As a key member of our innovation team, you will play a pivotal role in leading the development of pioneering digital experiences that connect with our core data platform, disruptive technologies such as LightSpray and future exploratory innovations. You will be responsible for designing and building scalable, cloud-native applications from the ground up. In addition to being hands-on, you will mentor team members, share your knowledge and expertise, and influence the technical direction of our innovation efforts.
