Role

We are seeking a Senior Principal Engineer to drive the architectural strategy and technical execution across our 80+ engineer Application Portfolio, encompassing all Web, Mobile, and Headless surfaces. This is a high‑impact, individual contributor role where you will set the vision for our technology transformation, bridging the gap between deep frontend architecture and scalable, agentic API‑first platforms. You will partner with Product leadership to drive customer‑obsessed engineering, ensuring that our technical choices directly accelerate product velocity and user value.

Responsibilities

• Architectural Vision: Define and drive the technical strategy for the entire Applications Portfolio, establishing deep frontend architecture standards (Web, Mobile, Headless) to ensure consistency, scalability, and performance.
• Mentorship & Leadership: Act as a key mentor and coach to senior engineering talent, fostering a culture of technical excellence, high‑impact decision‑making, and proactive problem‑solving.
• Product‑Engineering Synergy: Collaborate deeply with Product leadership to drive roadmaps, ensuring engineering strategy is inherently aligned with customer needs and product evolution.
• Strategic Alignment: Facilitate alignment and clarity across teams regarding goals, outcomes, and timelines for complex, multi‑team projects.
• Technology Transformation: Spearhead the evolution of our application architecture from a 'feature factory' model to a platform‑driven system, modernizing API layers and integrating emerging standards like the Model Context Protocol (MCP) to enable next‑generation agentic workflows.
• Design Systems Partnership: Partner closely with Design Systems teams to define and influence the evolution of shared UI components and design tokens, ensuring seamless integration with engineering architectural standards.
• Technical Governance: Identify and reduce systemic technical risks, enforce design principles, and raise the bar through hands‑on technical reviews and prototyping.

Requirements

• Extensive experience (15+ years) as a senior/principal‑level software engineer with deep expertise in Frontend architecture and large‑scale application systems.
• Proven success leading technology transformation across organizations of 80+ engineers.
• Deep understanding of modern API design (REST, GraphQL) and its application in highly distributed, agentic environments.
• Demonstrated experience with the Model Context Protocol (MCP) or similar agent‑integration patterns.
• Strong product mindset: proven history of collaborating with Product leaders to solve complex customer problems with customer‑obsession.
• Ability to balance high‑level architectural strategy with hands‑on, production‑level coding.
• Extensive experience evaluating and adopting new frontend technologies and frameworks, expertly balancing innovation with long‑term maintainability.
• Proven track record of designing and scaling robust frontend architectures that support high‑traffic, complex user interfaces across massive datasets.

Exceptional communication skills, with the ability to facilitate clarity and drive consensus across distributed teams.
