Abnormal AI is an AI-native cybersecurity platform protecting enterprises from advanced email attacks, account compromise, and human-targeted threats. The company helps security teams detect sophisticated attacks, investigate risk quickly, and automate response at enterprise scale.
You'll join the Critical Email Products (CEP) team within Message Security Products (MSP), working on backend systems that enable enterprises to consolidate on Abnormal and migrate away from legacy email gateways (SEGs). The CEP team owns a suite of security email features including URL Rewriting and Email Digest, with direct business impact—every capability shipped unblocks customers ready to move off their legacy SEG.
In this role, you will:
- 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
The team values moving fast, owning systems end-to-end, and maintaining a high engineering bar.
REQUIREMENTS:
Must Have:
- 3+ years of professional software development experience
- 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 (Cursor, GitHub Copilot, Claude)
- Event-driven systems experience (Kafka, SQS, or similar message queue/stream processing)
- 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
