Software Development Engineer, Security Platform

Twitch is the world’s biggest live streaming service, with global communities built around gaming, entertainment, music, sports, cooking, and more. It is where thousands of communities come together for whatever, every day.

We’re about community, inside and out. You’ll find coworkers who are eager to team up, collaborate, and smash (or elegantly solve) problems together. We’re on a quest to empower live communities, so if this sounds good to you, see what we’re up to on LinkedIn and X,  and discover the projects we’re solving on our Blog.

Twitch Security Platform builds and operates the foundational software, data, and automation that enable security at scale across Twitch. As a Software Development Engineer II (SDE II) on the Security Platform team, you will design, build, and operate critical services, pipelines, and tooling that power Twitch's security, privacy, and compliance programs.

Twitch Security Platform builds and operates the foundational software, data, and automation that enable security at scale across Twitch. As a Software Development Engineer II (SDE II) on the Security Platform team, you will design, build, and operate critical services, pipelines, and tooling that power Twitch's security, privacy, and compliance programs.

In this role, you will work at the intersection of software, security, privacy, and data engineering, contributing production systems that handle large-scale security telemetry, automate security workflows, and provide reliable data and services to internal teams. You will partner closely with engineers and product teams to solve real-world security problems through well-designed software.

You will own projects end-to-end from design and implementation through deployment and operational support for the systems that are business-critical and highly visible. The problems you work on will span areas such as security data ingestion and processing, detection and response automation, service-to-service authentication, vulnerability management, and privacy engineering. This is a broad platform charter, and priorities shift as the security landscape does; you should be energized by a wide surface area and comfortable moving fluidly between systems rather than anchored to a single one. 

This role is ideal for an engineer who enjoys working in ambiguous problem spaces, values operational excellence, enables peers, and wants to see their work directly improve Twitch's security posture at scale.

You can work from San Francisco, CA; Irvine, CA; or Seattle, WA.

• Own and deliver well-scoped software projects end-to-end, from design through production support.
• Partner across Security, Identity, Privacy, and Infrastructure on Twitch-wide initiatives.
•  Drive operational excellence: observability, reliability, and operational readiness for critical systems.
• Raise the engineering bar through design reviews, code reviews, clear technical decision-making and validation including AI-assisted output.
• Participate in, retrospectives, and technical discussions, influencing decisions through technical leadership.

• Bachelor's degree in Computer Science, Engineering, or equivalent practical experience.
• 3+ years building and operating production backend services with end-to-end ownership (design, deploy, operate).
• Deep fluency in a modern language (Go, Java, Python, or similar).
• Hands-on AWS: designing, deploying, and operating production services or pipelines, with IaC and safe rollout.
• Comfort driving clarity in ambiguous, evolving problem spaces.
• A track record of leading technical projects that span multiple services and parallel workstreams
• Strong cross-team communication able to disagree with data and commit once decided.

• Full-stack experience ownership across backend APIs and frontend experiences.
• Familiarity with security, data, and privacy systems, such as security or audit data lakes, cloud authentication and authorization flows, vulnerability scanning and remediation pipelines, and privacy or compliance-driven workflows (e.g., CCPA, GDPR-related controls).
• Experience working with large-scale event or log data, including event-driven architectures, asynchronous processing, or batch/streaming pipelines.
• Experience integrating AI-assisted development or analysis tools into engineering workflows, such as using LLM-powered tooling, automation, or MCP-style platforms to improve developer productivity or system insight.
• Familiarity with Twitch, either as a viewer or creator (or both!)
