Why Join Doppel
Doppel is building the future of social engineering defense. Our AI-native platform uses agentic AI to protect executives, employees, customers, and brands from phishing, impersonation, fraud, and other AI-powered threats across digital channels. We help some of the world’s most recognized brands detect and dismantle attacker infrastructure while strengthening employee resilience through threat-informed training and simulation. By unifying Digital Risk Protection, Human Risk Management and Email Security, Doppel connects threats into a real-time intelligence graph to power faster disruption, smarter defense, and modern security awareness at scale.
Backed by leading investors including Andreessen Horowitz and Bessemer Venture Partners, and trusted by leading enterprises, Doppel is a rapidly growing Series C startup building the future of social engineering defense. Our team combines deep cybersecurity expertise, operational rigor, and startup velocity to solve some of the internet’s most urgent trust and safety challenges.
What We're Building
We're building the AI-native social engineering defense platform.
This means we're designing scalable systems that monitor billions of domains, social media accounts, apps, dark web forums, etc., and leverage AI agents to identify and neutralize digital threats.
What You'll Do
Doppel's Forward Deployed Engineering team owns the onboarding of our biggest enterprise customers as effective and low touch as possible
You'll work directly with our largest enterprise customers alongside GTM and Product to understand their onboarding needs, scope and prioritize technical solutions, and build the end-to-end systems that get customers integrated with Doppel’s core offerings. You'll lead the technical direction of the whole FDE team while staying hands-on with our hardest integrations and most strategic deployments.
As Doppel's customer base and product portfolio expand, you'll help turn what we learn in the field into reusable capabilities that make every future deployment faster and easier.
Lead FDE technically. Set technical direction, mentor engineers, unblock complex projects, and raise the engineering bar while remaining hands-on.
Own our most strategic deployments. Join customers from technical discovery through production rollout, identifying onboarding friction, scoping solutions, and driving the engineering work required to get them live.
Build end-to-end solutions. Architect, build, and debug across APIs, webhooks, SIEM/SOAR platforms, identity systems, email infrastructure, and the broader enterprise security stack.
Turn field work into product. Identify patterns across customer deployments and turn bespoke solutions into reusable product and platform capabilities.
Make deployment increasingly scalable. Build the systems, automation, and internal tooling that make every new customer faster and easier to launch than the last.
Shape the product from the field. Create a tight feedback loop between customers, GTM, Product, and Engineering so what we're learning from our largest customers influences what we build.
Help shape FDE's technical boundaries. Develop strong judgment around what FDE should build, what should graduate into core product or platform, and where FDE should partner with other engineering teams.
What we’re looking for
Strong software engineering foundation. 6+ years building and shipping production software, with the technical depth to make architecture decisions and contribute directly to the codebase.
Technical leadership experience. You've set technical direction, mentored engineers, and driven complex projects while remaining hands-on.
Customer-facing technical depth. You've worked directly with complex enterprise customers, can uncover technical needs, and can turn ambiguous problems into scoped production systems.
Experience with enterprise systems. You're comfortable working across APIs, webhooks, identity and authentication (OAuth, SAML, SCIM), and enterprise infrastructure. Experience with security platforms or SIEM/SOAR ecosystems is a plus.
Product instincts. You recognize patterns across customer needs and know when something should remain customer-specific versus becoming a reusable product or platform capability.
High agency in ambiguity. You cut through organizational and technical blockers to get things done. You figure out who to pull in across Sales, Customer Success, Product, and Engineering, chase down missing context, and create the connections and processes needed to move customer problems from ambiguity to production.
Strong technical judgment and communication. You can move comfortably between a customer call, system design, debugging with an engineer, and working with Product on what should be built next.
AI-native mindset. Experience building with LLMs, agents, or AI-powered workflows is a plus, but we're most interested in engineers who are excited to use AI to change how technical customer work gets done.
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.
