If this sounds like you, let’s talk.

Who You Are:

We're looking for exceptional engineers who are passionate about our mission and have a strong desire to make a meaningful impact. The ideal candidate will have:

• Proficient in Scala/Java or a similar language; an expert in the majority of language constructs, able to apply them fluently to solve fairly complex problems.
• Designed a non-trivial distributed system (multi-tier) - storage layers, caching layers, application layers, understanding of failure modes, which are significantly different vs non-dist systems, with expertise in caching (memcached and/or redis) at scale.
• Microservice Architecture experience, especially with high throughput and low-latency systems.
• Experience with performance tuning.
• Participated in a complex systems migration involving multiple phases with dark reads, dark writes, light reads, light writes.

What You’ll Do:

In this role, you will:

• Work in a fast-paced, collaborative environment where ideas are discussed and challenged openly.
• Deliver new features and improve the reliability of our core services including the major read/write paths for Posts, Users, Social relationships, and more.
• Identify major system bottlenecks, or flaws in business logic, and proactively address them.
• Take ownership over core product problems, be able to come up with your own solutions that you love, and prove through data that it is impactful at scale.
• Work across the stack to solve problems; there is no reliance on another engineer or team to get something done for you.
