- Experience leading initiatives around authentication, authorization, user settings, tenant management, or auditability
- Experienced with multi-persona products, particularly building features for Enterprise clients
- You think in terms of platforms and systems, not just features, and you balance security, usability, and scalability in every decision
- Strong background in backend engineering and/or platform engineering
- Expertise in at least one object-oriented programming language (Python strongly preferred; open to Go, Java, C++, or similar)
- Familiarity with ETL pipelines, data flow orchestration, and database performance optimization (PostgreSQL, Neo4j, or equivalent)
- Understanding of cloud infrastructure and services (AWS, Azure, or GCP), including networking, compute, and storage fundamentals
- Exposure to infrastructure-as-code and deployment concepts (e.g., Terraform, Docker, Kubernetes, CI/CD tooling)
- Experience with observability and monitoring stacks (Prometheus, Grafana, OpenTelemetry, etc.)
- Understanding of security and reliability best practices, especially in a multi-tenant SaaS or cybersecurity environment
- Knowledge of Linux-based systems (Ubuntu, Kali, etc.) and modern development practices for distributed environments
- We welcome candidates from all backgrounds and experiences, and we encourage all qualified individuals to apply
Desirable
- Experience designing multi-tenant SaaS platforms or MSP-oriented capabilities
- Exposure to audit/compliance frameworks (SOC2, FedRAMP, ISO 27001)
- Background in cybersecurity, identity management, or enterprise SaaS security features
- Experiencing managing tech leads or other managers
What the job involves
- We’re looking for a Senior Engineering Manager to lead our User Platform & Enterprise team — a high-impact group within our Application Platform team which drives all user settings and enterprise capabilities across the product, and helps improve our client experience overall
- This is a technical leadership role focused on driving excellence in Enterprise user experience, creating a cohesive user platform vision, and pushing for explainability and scalability in our licensing framework
- The User Platform & Enterprise team owns our base user platform experience, our entitlement framework and feature flagging systems, and many of our key enterprise differentiating features
