What you'll be doing:

- Build and operate large-scale, reliable and performant distributed systems to support Discord's real time features and services.
- Collaborate with product and infrastructure teams to develop primitives that provide compounding leverage for Discord engineering by reliably storing and serving user data, while also protecting the safety of our user data.
- Exercise "First Principles Thinking" to always deliver what matters most to our users.

What You Should Have:

- 7+ years of experience building performant distributed systems.
- Genuine interest and enthusiasm in solving complex technical problems, investigating regressions, and finding ways to improve our systems' performance.
- Strong understanding of observability and monitoring.
- Flexibility in undefined environments and excitement about devising solutions for complex technical challenges.
- Familiarity with reading and writing code in large existing codebases
- Demonstrated capability and empathy when collaborating with other engineering teams to solve issues.
- A wide range of experience across many domains and technologies, and a willingness to venture into new ones.

Bonus points:
