Senior Software Engineer, Enforce - Safety Processing

The Safety Processing team builds the infrastructure and decision systems that enable accurate, efficient, and fair content moderation at scale. Keeping our users safe is foundational to everything we do.

The Enforce Squad is a newly formed squad within Safety Processing, responsible for the systems that translate safety decisions into real-world actions such as bans, warnings, content removal, and legally mandated reporting. These systems touch every user who violates policy and every piece of content that gets actioned. We're looking for a Senior Software Engineer who can take ownership of complex, critical infrastructure and help us stabilize, scale, and evolve Discord's enforcement systems.

What you will do:

• Own high impact projects within a complex distributed system from end-to-end that help Safety at Discord scale.
• Improve production services that process millions of enforcement decisions per day, including participating in the team's 24/7 on-call rotation.
• Apply an adversarial mindset to enforcement systems to anticipate abuse patterns, edge cases, and failure modes in systems that must be accurate, fair, and legally compliant.
• Partner with Trust & Safety, Policy, ML, Data Science, and Legal teams to deliver enforcement changes ranging from policy updates to compliance-critical pipeline improvements.
• Contribute to measurement foundations by working with Data Science to define and baseline enforcement metrics like recidivism rate, over-enforcement rate, and unintended churn.

What you should have:

• 4+ years of professional software engineering experience with a focus on backend services and infrastructure.
• Strong programming skills in Python
• Experience building and operating distributed systems and production services at scale ( use GCP, PostgreSQL, Redis, Pub/Sub, KKV, and gRPC).
• Demonstrated ability to own projects end-to-end and deliver results on time, including in ambiguous or transitional environments.
• Strong debugging skills and ability to navigate complex, multi-service codebases. Many of our systems have deep interdependenci
