What are Sr Frontend Engineers?

Sr Frontend Engineers are experienced software developers who specialize in building and optimizing the user-facing parts of web applications. They lead the design and implementation of complex interfaces, ensure performance and accessibility, and often mentor junior engineers. Their role includes working closely with designers, backend developers, and product managers to deliver high-quality, scalable front-end solutions. Typically, they have a deep understanding of modern JavaScript frameworks, web standards, and best practices.

How does a Sr Frontend Engineer typically collaborate with backend teams to deliver high-quality user experiences?

As a Sr Frontend Engineer, you’ll frequently work closely with backend developers to define APIs, discuss data requirements, and troubleshoot integration issues. Regular collaboration involves participating in planning meetings, code reviews, and joint debugging sessions to ensure frontend and backend components align seamlessly. This cross-team communication is essential for delivering responsive, efficient, and scalable user interfaces, and it also provides opportunities to influence architectural decisions and improve overall product quality.

 The Role: Senior Frontend Engineer
We're looking for a Senior Frontend Engineer to join our growing team in the US. This is a high-impact role where you'll design and build world-class user interfaces for our flagship platform. You'll work closely with design, product, and backend teams to deliver intuitive, performant, and elegant user experiences - powering AI-driven insights for enterprise data teams.
This is an opportunity to own key frontend features end-to-end, contribute to design system evolution, and shape the visual language of our platform as we scale.
What You'll Do
  • Build responsive, accessible, and high-performance frontend components and workflows using React (or similar frameworks)
  • Collaborate closely with designers and backend engineers to implement scalable, data-driven UI/UX patterns
  • Lead frontend development for core features - from wireframes to production deployment
  • Help evolve and maintain our internal component library and design system
  • Optimize frontend performance, bundle size, and overall UX responsiveness
  • Ensure frontend security, testing, and CI/CD best practices are consistently applied
  • Participate in code reviews, architecture discussions, and cross-functional initiatives
  • Identify areas for UI/UX improvement and contribute ideas to enhance user workflows
  • Stay current with modern frontend trends, frameworks, and tooling
What We're Looking For
  • 3-6 years of frontend engineering experience with modern JavaScript/TypeScript frameworks (preferably React)
  • Strong understanding of HTML, CSS, browser behavior, and cross-device compatibility
  • Experience building and maintaining large-scale web applications with clean architecture
  • Passion for UI/UX - you care about detail, polish, and usability
  • Comfortable working in a fast-moving, collaborative startup environment
  • Familiar with working on RESTful/GraphQL APIs, frontend performance tools, and testing frameworks (e.g. Jest, Cypress)
  • Excellent problem-solving, debugging, and communication skills
  • Ownership mindset - you're proactive, self-directed, and thrive in ambiguity
Bonus Skills
  • Experience with design systems
  • Familiarity with data-heavy visualizations or analytics dashboards
  • Exposure to enterprise SaaS products or developer-focused tools
  • Knowledge of cloud platforms (AWS/GCP) and CI/CD workflows
  • Contributions to open-source frontend libraries or UI frameworks
Why Join Us
  • Collaborate with world-class founders & engineers.
  • Build a stunning, scalable frontend for a cutting-edge GenAI + data platform
  • Own major product surfaces and influence design direction from the ground up
  • Tackle meaningful product and UX challenges in cloud and data domains
  • Grow rapidly in an environment that values autonomy, creativity, and velocity
Ready to build beautiful, intuitive interfaces that power the future of cloud data operations? Let's talk.
We may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses and identifying potential inconsistencies or verification signals in application materials based on available information. These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans. If you would like more information about how your data is processed, please contact us.
