Role Overview

As a Staff Platform Engineer, you operate with broad organizational impact. You will set technical direction, design durable platform abstractions, and partner closely with senior engineers, engineering managers, and product leadership to ensure our platform enables rapid innovation without compromising stability, security, or compliance.

This role blends deep hands-on engineering expertise with systems thinking and influence. You will lead complex cross-team initiatives, establish best-in-class platform standards, and mentor engineers while remaining directly involved in building and operating core platform capabilities.

On the engineering side, we're pioneering the use of AI as a code collaborator. We need engineers who have gone beyond experimentation—who actively use Claude Code, Cursor, GitHub Copilot, or similar tools to ship production code faster while maintaining exceptional quality standards. If you have strong opinions about AI-augmented development workflows backed by real experience, we want to talk with you.

Responsibilities

• Define and document enterprise-wide standards for AI integration, establishing prompt engineering patterns and validation frameworks that scale development velocity without compromising architectural integrity.
• Orchestrate the identification of AI-generated code pitfalls—such as security vulnerabilities and over-abstraction—while quantifying the business impact through PR velocity and quality metrics.
• Lead the design and evolution of highly available, scalable infrastructure, ensuring the platform remains resilient under the demands of multi-disciplinary engineering teams.
• Architect robust CI/CD ecosystems and developer tooling, focusing on eliminating friction in the software delivery lifecycle and driving organization-wide productivity.
• Serve as a subject matter expert for platform security, implementing sophisticated safeguards and compliance standards to protect the integrity of the firm’s systems.
• Drive the strategic roadmap for system observability, implementing advanced monitoring, tracing, and alerting architectures to ensure peak operational reliability.
• Act as a primary technical liaison between engineering, product, and quantitative teams to translate complex requirements into scalable, innovative platform solution
