Role Overview:

As a Principal Platform Engineer, you will play a key role in designing, building, and scaling the infrastructure and internal tooling that powers our engineering teams. You’ll focus on delivering secure, scalable, and developer-friendly platform capabilities that accelerate product delivery while improving operational efficiency and resilience.

In this hands-on role, you’ll work closely with engineers and cross-functional teams to evolve our core platform - contributing to areas such as deployment workflows, observability, data services, and networking. You will be a strong individual contributor who also mentors others and champions best practices across the team. Your work will enable autonomy, consistency, and security across the engineering organization.

Key Accountabilities & Responsibilities:

Designing and implementing platform features and infrastructure that support the scalability, security, and reliability of our systems.
Building reusable, self-service components that abstract complexity and improve developer productivity.
Writing high-quality, maintainable code and applying infrastructure-as-code principles for repeatable, auditable changes.
Partnering with product, security, and operations teams to align on requirements and ensure solutions meet evolving business and technical needs.
Participating in design and architecture discussions to ensure platform scalability, reliability, and long-term maintainability.
Supporting incident response and contributing to post-incident reviews and platform reliability improvements.
Driving adoption of best practices in automation, observability, and secure-by-default infrastructure design.
Mentoring junior engineers and contributing to a culture of learning, collaboration, and technical excellence.
Taking part in a shared on-call rotation, supporting platform services and contributing to incident resolution and reliability improvements.
Lead fullstack reliability. Operate across a modern web stack (TypeScript, React, Python). While not frontend-heavy, you’ll diagnose and resolve issues across the stack and drive reliability improvements end-to-end.
Mentor and multiply. Raise the reliability IQ of the broader engineering team. Establish SRE best practices, conduct production-readiness reviews, and mentor engineers on operational thinking.

Strong problem-solving skills, with the ability to navigate complexity and make sound technical decisions.
Excellent collaboration and communication skills, with the ability to work across teams and disciplines.
A mindset of ownership and continuous improvement, with a passion for creating scalable and developer-friendly systems.
