Job description

As a Senior Security Engineer on the Detection & Response (D&R) team, you will protect Roblox's user community alongside its underlying global platform infrastructure. Operating at the intersection of security engineering and software development, you will design high-fidelity detection logic, engineer scalable security data pipelines, and respond directly to security incidents. In this hybrid role, you will balance open-source frameworks, commercial security tools, and custom in-house systems to protect both enterprise systems and production platform environments.

Key Responsibilities

Detection Engineering & Data Pipelines

• End-to-End Detection Engineering: Lead cross-functional engineering partners through threat modeling and logging intake to build, test, and deploy actionable, high-fidelity detection rules with minimal false-positive rates.
• Security Data Pipelines: Build and maintain scalable, reliable, and efficient security data pipelines and contribute directly to internal security software platforms across shared codebases.
• Incident Response & Service Reliability: Participate in an on-call rotation to maintain the operational health, uptime, and efficacy of detection and response infrastructure, driving incidents to root-cause mitigation.

Security Culture & Pragmatic Problem Solving

• Cross-Functional Security Partnership: Serve as a trusted security advocate across Roblox, fostering a culture grounded in ownership, transparent communication, and shared security responsibility.
• Pragmatic Architecture: Balance open-source tooling, commercial security vendor solutions, and custom in-house software builds to solve complex, large-scale security challenges.

Requirements

Technical Depth & Security Engineering Foundations

• Experience Track: 3+ years of professional experience in Security Data Engineering, Detection Engineering, or Security Operations.
• Software Engineering Skills: Proven capability to build efficient, reliable, and scalable security tools and services using programming languages like Golang or Python.
• Data & Infrastructure Tooling: Hands-on experience with Infrastructure-as-Code (Terraform) and querying/analyzing complex datasets using SQL.
• Core Security Fundamentals: Demonstrated ability to evaluate risk, architect compensating security controls, triage alerts, and lead root-cause mitigation during incident post-mortems.
• Collaborative Development: Comfortable diving into shared engineering codebases and submitting GitHub Pull Requests (PRs) to ship security capabilities.

Preferred Qualifications

• Hands-on experience scaling security data lakes or SIEM architectures (e.g., Snowflake, Panther, Databricks, Elastic, or Kafka).
• Direct experience authoring detection logic for cloud-native infrastructure (AWS/GCP) and container environments (Kubernetes).
• Active contributions to open-source threat detection projects or incident response frameworks.

Total Rewards & Benefits

• Compensation & Equity: San Mateo base salary range ($196,750 – $243,290 USD) + competitive Roblox equity compensation package.
• Healthcare & Wellbeing: Comprehensive health, dental, and vision insurance packages for employees and eligible dependents.
• Onsite Perks & Campus: Modern San Mateo headquarters featuring daily catered meals, team events, and state-of-the-art technical setups.
• Time Off & Retirement: Generous vacation policies, paid company holidays, paid parental leave, and 401(k) matching programs.
