## Job description

## Why Join Doppel

Doppel is built to outsmart one of the great threats AI presents: mass-manufactured social engineering. Countless scams, deepfakes, and other social engineering attacks are surging across every digital channel: websites, social media, ads, encrypted messaging apps, mobile, and more. Our mission is simple but bold: make the internet a safer place by outsmarting the world’s fastest-evolving digital threats. Backed by a16z and Bessemer and trusted by some of the world’s most recognized brands (OpenAI, United Airlines, Coinbase, etc.), Doppel is growing fast. If you’re driven to solve real-world problems with bold technology, we’d love to meet you.

## What We're Looking For

We’re looking for a senior frontend engineer to elevate every aspect of UI/UX across our core product platform. You’ll work closely with our lead designer to create a cohesive, performant, and modern user experience that instills confidence and trust in enterprise customers. Your work will directly influence seven-figure deals and how customers and internal teams interact with our product.

## What You'll be Doing

Doppel's Frontend Platform team is building toward something that hasn't really been done: a frontend platform so complete that product teams no longer need to do frontend development. Designers and product engineers describe what they want; the platform — a rigorously constrained design system, agent-driven code generation, and paved-road infrastructure with permissions, telemetry, turns it into production code. We've already proven the foundation works: our modern stack (React 19, Relay, a custom UI kit with agent-enforced golden paths) is explicitly designed so AI agents generate reviewable, production-safe frontend code. Your job is to close the remaining gap between design and production. This is a small team with an ambitious, still-forming charter at a company rapidly expanding its product portfolio — you'll shape what it becomes, and every product Doppel ships will run on what you build.

- Build and maintain the frontend infrastructure every product runs on: the application shell, data layer, routing, auth, and build/deploy pipeline — so product teams ship features, not frontend plumbing.
- Evolve the design system from a component library into a contract: constrained, composable primitives with tokens, docs, and guardrails tight enough that generated code is correct by construction.
- Build the design-to-production pipeline: the tooling, agent workflows, and review guardrails that let designers and product teams go from a design to a shipped, production-quality surface without hand-writing frontend code.
- Make the platform safe by default: permissioning and packaging gates, observability, accessibility, and internationalization baked into the primitives rather than re-implemented per feature.
- Own production health of the shared client: monitors, SLOs, and ownership routing so failures page the right team automatically and the platform stays trustworthy enough to build on blindly.
- Package the platform for scale: a versioned component library and scaffolding that lets new apps and product surfaces spin up on the paved road from day one.
- Partner closely with design and product teams as your customers — their velocity is your success metric.

## Who You Are

- 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.

## Why This Role Matters

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.

## What We Offer

🚀 A mission-driven culture with low ego, high ownership, deep customer obsession, and exceptional talent density 🍽️ Free lunch and dinner in the office 🌴 Flexible PTO ✈️ Quarterly team offsites

- **Human Risk Management**: Strengthens employees against real attacker tactics (deepfakes, vishing, multi-channel pretexting) via training and simulation.
- **Email Security**: Agentic detection and response powered by the Doppel Threat Graph — catches what traditional filters miss and stops campaigns in their tracks.
- **Phishing Triage**: Uses agentic AI to turn employee-reported signals into machine-speed remediation and defense.
- **Security Awareness Training**: Tailored, deepfake-enabled, threat-informed training and personalized coaching.
- **Simulation**: Realistic phishing simulations that reveal real vulnerabilities and build response readiness.
- **Executive Protection**: Continuous monitoring of personal data exposure and threat activity across open and dark channels for high-risk leaders.
- **Brand Protection**: Continuous detection and disruption of impersonation and fraudulent activity across digital channels.

## Market Standing
- **Valuation/Total Funding**: Not disclosed. Backed by prominent investors including **Bessemer Venture Partners**, **Andreessen Horowitz (a16z)**, **Amex Ventures**, **NTT DOCOMO Ventures**, **Strategic Cyber Ventures**, **9Yards Capital**, **Sozo Ventures**, **SVAngel**, and others.
