Job Application Deadline: 08/31/2026
The opportunity
As a Senior Frontend Software Engineer, your expertise will directly shape the architecture, quality, and long-term direction of our customer-facing products. You will drive the technical strategy for our end-to-end user experience, ensuring it scales with exponential growth and increasingly complex business requirements. This role is ideal for a seasoned engineer who leads by example - someone who thrives on translating complex data and workflows into intuitive interfaces, takes deep ownership of the full frontend lifecycle, and is energized by mentoring others while delivering high-impact work across our portfolio.
What You'll Do
  • Design and Development: Design, build, and maintain highly performant, accessible, and responsive web applications using our core frontend stack and frameworks.
  • Component Ownership: Take end-to-end ownership of key UI components and design system elements, including long-term strategy for performance optimization, cross-browser compatibility, and accessibility standards.
  • Mentorship: Actively mentor junior and mid-level engineers through code reviews, pair programming, and knowledge sharing, fostering a culture of continuous growth and technical excellence.
  • Collaboration: Partner closely with UX designers and engineer leaders (Principals and Staff) to translate business requirements and design specs into polished, production-ready interfaces.
  • Quality Assurance: Champion a culture of quality by writing comprehensive unit, integration, and end-to-end tests, leading code reviews, and advocating for best practices in accessibility and maintainability.
  • Observability: Define and implement frontend monitoring and alerting strategies using Datadog to track performance metrics, error rates, and user experience health in production.
  • Incident Management: Lead the response and resolution of frontend-related production incidents, conduct root cause analyses, and drive the implementation of preventative measures at a systemic level.

The Skills and Experience You'll Bring
  • At least 7 years of experience in frontend software development with a consistent track record of delivering high-quality, high-impact work at scale.
  • Deep proficiency in modern JavaScript/TypeScript and the broader ecosystem, including build tooling, bundlers, and performance optimization.
  • Expert-level knowledge of frontend frameworks such as Angular, React, and/or web components, with the ability to make and defend architectural choices between them.
  • Proven experience designing, building, and evolving component libraries or design systems used across multiple teams or products.
  • Strong command of RESTful and GraphQL APIs and patterns for integrating complex frontend applications with backend services.
  • Hands-on experience deploying and managing frontend applications on AWS (e.g., CloudFront, S3), with an understanding of CDN strategy, caching, and infrastructure as it relates to frontend performance.
  • Solid understanding of containerization (Docker) and CI/CD pipelines as they apply to frontend development workflows.
  • Deep expertise in Datadog or equivalent tools for frontend monitoring, distributed tracing, logging, and observability.
  • Mastery of web performance best practices, browser rendering pipelines, and accessibility (WCAG) standards - and the ability to evangelize these across the organization.
  • Demonstrated ability to lead technical discussions, influence cross-functional stakeholders, and drive consensus on complex decisions.
  • Experience working with AI and/or Spec Driven Development
  • Excellent written and verbal communication skills, with experience presenting technical concepts to both technical and non-technical audiences.
  • A Bachelor's degree in Computer Science, a related technical field, or equivalent practical experience.

For starters, we have a hybrid work environment, but we also know what makes a great workplace. We have a time-tested and resolute set of operating values predicated on integrity, mutual respect, open communication, and executing with excellence.
