## What You'll Do

- Build and maintain backend services powering CEP's product surface
- Design and evolve event-driven pipelines (Kafka consumers, Airflow DAGs) that process email traffic reliably at enterprise scale.
- Work across a multi-tenant, multi-cloud deployment footprint (M365 and Google Workspace customers, FedRAMP environments)
- Leverage AI-augmented development tools to explore solutions, refine outputs, and deliver reliable production outcomes faster.
- Collaborate with product and cross-functional partners to iterate quickly on features that move customers from legacy SEGs to Abnormal.
- Contribute to service reliability, observability, and operational quality as the team scales its product surface.

Must Haves

- 3+ years of professional experience in software development.
- Backend development experience with Python or Golang.
- Experience building scalable, enterprise-grade applications.
- Knowledge of cloud platforms (AWS, GCP, or Azure) and containerization (Docker, Kubernetes).
- Strong fundamentals in computer science, data structures, and performance optimization.

## Nice to Have

- Experience with AI development tools such as Cursor, GitHub Copilot, or Claude.
- Experience with event-driven systems: Kafka, SQS, or similar message queue / stream processing patterns.
- Familiarity with email delivery pipelines, email authentication standards (DMARC, DKIM, SPF), or email security products.
- Exposure to multi-tenant SaaS architectures or enterprise integrations (M365, Google Workspace APIs).
- Experience improving service reliability, observability, and operational tooling in production systems.
- Prior work in cybersecurity, email security, or compliance-adjacent domains.

- **Mission statement**: "Stop crime with AI and bring cybersecurity from the future to defenders today."

## Products & Services
- **Abnormal Behavioral Security Platform**: An AI-native, cloud-based platform that builds behavioral baselines for every user and entity in an organization to detect anomalies that indicate attacks.
  - **Email Security**: Autonomous detection and remediation of BEC, phishing, and account takeover attacks via API-based, cloud-native architecture. Deploys in 60 seconds with no MX changes.

## Market Standing
- **Valuation/Market Cap**: Not publicly disclosed (last reported Series D valuation was $2.6B in 2022)
- **Key Metric**: Over 25% of the Fortune 500 are customers. The company has stopped millions of attacks and saved billions in financial losses.
- **Notable Investors/Partners**: Insight Partners, Greylock Partners, Menlo Ventures, CrowdStrike Falcon Fund (strategic investor)
- **Growth Signals**: The company is AI-native from day one, with revenue growing rapidly. It is expanding its platform from email security into identity, insider threat, and AI governance. Headcount has grown significantly, and the company continues to hire across engineering, GTM, and operations.

## Competitive Advantages
- **Behavioral AI Moat**: Unlike signature-based or rules-based security tools, Abnormal builds a unique behavioral baseline for every organization and user. This allows it to detect novel attacks that no other vendor sees.
- **AI-Native Operations**: The company doesn't just build AI products—it runs its entire business (product, CS, finance, HR) with AI agents, compounding its speed of innovation.
- **Deep Enterprise Trust**: Over 25% of the Fortune 500 give Abnormal the authority to autonomously make security decisions, a level of trust very few vendors achieve.
- **Founding Team Origins**: Founders came from adtech (building anomaly-detection AI at scale) rather than traditional cybersecurity, giving them an outsider's perspective that led to the behavioral AI approach.

## Strategic Focus
- **Platform Expansion**: Moving beyond email security into identity, insider threat, and AI security, building a unified behavioral security platform.
- **AI-First Product Development**: Using AI agents to compress product development cycles from quarters to weeks, rapidly launching new products.
- **Operational Efficiency**: Embedding AI across every internal function to drive automation and efficiency, allowing the company to scale without linear headcount growth.
- **Market Leadership**: Capitalizing on the wave of AI-generated attacks to position behavioral AI as the only viable defense.

## Why Work Here
- **Remote-First Culture**: From day one, Abnormal has been remote-first. Employees have the choice to work from home, from hub offices, or from co-working spaces (WeWork). Async work is the default, with deliberate synchronous overlap time. [abnormal.ai](https://abnormal.ai/careers/culture)
- **High Autonomy, High Accountability**: No micromanagement. Clear expectations. Growth is based on impact, not tenure or title. "You don't wait your turn." [abnormal.ai](https://abnormal.ai/careers/culture)
- **AI-Native Work Environment**: Every employee, regardless of role, gets access to the best AI tools and is expected to use them. The company rebuilds work processes around what AI makes possible—not by bolting AI onto old workflows. [abnormal.ai](https://abnormal.ai/careers/culture)
- **Compressed Growth Timeline**: Because everything moves fast with AI, impact that would take quarters elsewhere happens in weeks. One person can do what used to take a team. Outsized impact is rewarded proportionally. [abnormal.ai](https://abnormal.ai/careers/culture)
- **Transparent and Direct Culture**: "We say what's true, even when it's uncomfortable." Leaders are accessible, teams share learnings openly, and new hires get real ownership immediately. [abnormal.ai](https://abnormal.ai/about)
- **Notable Perks**: Compensation is tied to impact, not role. The company offers flexibility as infrastructure, not a benefit. Employees see direct results from their work in a fast-growing, mission-driven company.
