As a Frontend Engineer at Carbon, you’ll take a leading role in shaping the user experience of our two flagship in‑house platforms:
Graphene Insights (our analytics engine) and Graphene Studio (our proprietary data preparation environment).

This is a hands‑on role at the core of our technology strategy, working closely with designers, engineers, and end users to deliver exceptional interfaces that power smarter underwriting.

• Own the end‑to‑end front‑end delivery for Graphene Studio and Graphene Insights from interaction design and UX flow through to production‑ready implementation
• Champion front‑end excellence across information architecture, interaction design, accessibility, performance, and code quality
• Build responsive, accessible, modern React UIs using clean, testable, well‑structured Type Script/Java Script
• Collaborate across the stack, partnering with engineers for code reviews, CI/CD improvements, and API integration
• Work directly with end users to gather feedback, translate needs into features, and refine the UX of complex analytical workflows
• Operate in a tight‑knit, agile team with a culture of shared ownership and no silos with opportunities to gain exposure across the full stack
• Take ownership of key components of the platform and help steer the future of the Graphene product suite
• Participate in client demos, contributing to how we present the platform both internally and externally
• Work closely with the business to build deep understanding of underwriting, delegated authority workflows, and our analytics products

We don’t expect perfection but we value curiosity, ownership, and strong engineering instincts:

• 3+ years’ experience in UI/UX for complex web applications, with a portfolio that demonstrates strong product thinking
• 3+ years building production front‑end applications in React (Type Script preferred)
• Strong skills in JavaScript/Type Script, with Python exposure seen as a bonus
• Cloud experience, we use GCP but AWS / Azure exposure is also valued
• Interfacing with API’s
• Experience in a start‑up or scale‑up environment, or an appetite to work in one
• A computer science or similar technical degree, or equivalent professional experience.
• Any independent or open‑source projects are a big plus, we love seeing what you build.
