Frontend Engineer, Platform

5+ years of software engineering experience with deep expertise in React and TypeScript, building and operating production web applications.

Experience owning platform-level frontend work: design systems, component libraries, build tooling, data-layer patterns (Relay or similar GraphQL clients), or frontend infrastructure other engineers build on.

Genuine excitement about AI-assisted development — you see agents as a way to raise the abstraction level of frontend work, and you want to build the rails that make that safe.

A platform mindset: you measure success by what other teams (and designers) can ship without you, not by features you shipped yourself.

Comfort operating in ambiguity — the team's charter is being defined in real time as the company grows, and you'll shape it rather than inherit it.

Familiarity with production monitoring and performance work (RUM, SLOs, error budgets) is a strong plus.

Experience collaborating deeply with designers — design tokens, Figma workflows, Storybook-driven development — is a strong plus.

Strong communication skills: your customers are product teams, designers, and backend platform engineers.

Product-minded, highly autonomous, and comfortable in a fast-paced startup environment.

You’ll define how our users, customers and internal teams, experience Doppel’s core platform. Your work will directly shape the look, feel, and velocity of the company’s most visible product surface.

Doppel is the first platform built to dismantle digital deception at scale. We scan over 150 billion entities daily and deploy continuously adaptive AI SOC agents, paired with expert human analysts, to uncover and disrupt the infrastructure behind phishing, impersonation, and online fraud before attacks can spread. Our Threat Grid turns every customer signal into shared intelligence, making each disruption smarter, faster, and more effective.

We’re not just another cybersecurity company. We’re defining the future of social engineering defense, where trust is protected, and deception becomes unprofitable. Backed by top-tier investors and trusted by some of the world’s most recognized brands, Doppel is growing fast. If you’re driven to solve real-world problems with bold technology, we’d love to meet you.
