Principal Engineer

The Principal Engineer is a critical, senior leadership role responsible for driving the technical strategy, architectural coherence, and engineering excellence across several key product areas. This role acts as a bridge between high-level business goals and on-the-ground technical execution, ensuring the product is built correctly, efficiently, and with a long-term vision. The Principal Architect is expected to drive technical excellence by balancing immediate execution needs with the long-term health and scalability of the product's architecture, while understanding the business and customer needs.

What you'll do

• Architectural Leadership & Strategy: Serve as the technical authority for multiple core product areas, ensuring all architectural decisions directly support the business objectives for those areas. Establish and maintain organization-wide technical standards, architectural patterns, and coding best practices to ensure consistency, security, performance, and maintainability across all teams. Support decision making by providing expert architectural guidance and data-driven recommendations to leadership and engineering teams, facilitating timely and sound technical decisions.
• Technical Management & Mentorship: Directly mentor, guide, and lead the technical direction of the Tech Leads and senior engineers within the domains, fostering a high-performance engineering culture. Oversee and approve key design documents and high-level architectural proposals, ensuring they adhere to organizational standards and the own building and maintaining a long-term architectural roadmap. Act as an escalation point for complex technical challenges, actively supporting teams in overcoming significant architectural hurdles or design issues.
• Communication & Vision: Pull teams up to give them the big picture and let them see connections: Define and communicate the overall architectural vision and strategy to engineering teams, helping them understand how their individual contributions connect to the broader product and business goals. Report on roadmap: Regularly report progress, risks, and technical insights related to the architectural roadmap to executive and product leadership.
