As a Staff Engineer, you will:

• Lead complex technical initiatives that span multiple teams and systems.
• Help define architectural direction, establish engineering standards, and improve developer workflows.
• Guide the evolution of our front-end platform and design system.
• Mentor engineers, influence technical strategy, and accelerate engineering effectiveness across the organization.

This role is ideal for engineers who enjoy solving ambiguous problems, influencing technical direction beyond their immediate team, and building systems that enable other engineers to move faster.

Qualifications

• 8+ years of experience building modern web applications used in production at scale.
• Deep expertise in JavaScript/TypeScript and React.
• Strong understanding of modern front-end architecture and application design.
• Experience leading large technical initiatives across multiple teams.
• Experience designing reusable component systems and scalable UI patterns.
• Strong knowledge of application state management, asynchronous data flows, and API integration patterns.
• Experience improving front-end performance, reliability, and maintainability.
• Strong debugging and problem-solving skills across both front-end and full-stack systems.
• Excellent written and verbal communication skills.
• Experience mentoring engineers and influencing technical direction.
• Ability to thrive in fast-moving, highly collaborative environments with evolving priorities.

Requirements

• Experience building platforms, frameworks, or shared engineering infrastructure.
• Experience with GraphQL and modern API-driven architectures.
• Experience working in a monorepo environment.
• Experience with modern build systems and tooling.
• Familiarity with cloud-native environments and AWS.
• Experience with observability and monitoring tools such as Datadog.
• Experience working closely with Product Design and Design Systems.
• Startup experience, particularly in high-growth environments.
• Cybersecurity or offensive security domain experience.
• Experience leveraging AI-assisted development workflows and engineering tooling.

Benefits

• Inclusive Team: We value diversity and promote an inclusive culture where everyone can thrive.
• Growth Opportunities: Be part of a dynamic and growing team with numerous career development opportunities.
• Innovative Culture: Work in a collaborative environment that encourages creativity and out-of-the-box thinking.
