Role
Who you are
- Experience leading teams of 6+ cross functional software engineers
- Proven experience leading highly technical backend or platform engineering teams — ideally within a SaaS, cybersecurity, or cloud-scale environment
- Experience leading initiatives around API platforms, headless customer experiences, or agent-based customer flows
- Experience with an integrations platform, particularly with an eye to build speed for new integrations
- 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
Desirable
- Experience with common security schemas/frameworks (OCSF, MITRE, ECS)
- Experience integrating with security vendors (Crowdstrike, Splunk, Palo Alto)
- Experience working with common ticketing vendors (Jira, ServiceNow)
- 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 Integrations & API team — a high-impact group within our Application Platform team whose mandate is critical to the scalability of our platform
- This nascent team will help push our existing APIs to be first-class citizens, building the consistent, well-documented foundation that powers every integration and allows customers to build their own agentic workflows atop our platform
- No less critical, this team will build strategic integrations to unlock critical new features atop mountains of complimentary data from users own systems
- We want to meet users where they are at with their current tooling, and use the products they already have in their ecosystem to drive the find-fix-verify loop with greater accuracy and less downtime
- This is a technical leadership role focused on driving excellence in fundamental capabilities - our API platform and our integrations platform
- We expect this individual to help drive long term sustainable strategy around integrations- evaluate the existing market, partner closely with product to understand customer needs, and execute on targeted short term plays which feed into the longer product vision
- This is an ideal opportunity for someone who has lived and breathed Integrations in a past life, and understands the power that a scalable API platform can allow for an entire class of power-users
