Genius is looking for a Full Stack Engineer to architect and implement new features.
We’re looking for makers with a sophisticated code sense: folks who’ve built cool things, but who can also maintain and scale those things, and who feel at home deep in the guts of a library.
The best candidates will have professional experience on a web stack with millions of users, but there are no hard requirements for the job.
We don’t care which languages and tools you use, just that you’re fluent with them.
Facility with Ruby and Rails is a plus, but the “full stack” involves a lot of technologies: frontends, APIs, databases (relational and not), job queues, etc.
So the main thing is to be versatile and relentlessly curious.
Build and maintain web application features, primarily with Rails
Work closely with application infrastructure to scale backend services to tens of thousands of requests per minute
Develop the APIs that our Android and iPhone apps and web frontend consume
Write PostgreSQL queries and migrations that scale to large tables with 50M+ rows
Work closely with product team to define feature specifications
Occasional on-call duty to respond to urgent bugs or outages
Design an activity stream scalable to 100M+ events and a filterable “firehose” interface for consuming them
HTTP-cache all pages at the edge for logged-out users only
Develop a system for anchoring annotations to arbitrary DOM that can change out from under you
Calculate document ownership based on edit history with hundreds of distinct authors
Develop representation for rich text that’s portable to native iOS and Android environments
Create framework for caching partial templates
Design a domain-specific language and implementation of site-wide rate limits for spammy or abusive behavior
Fingerprint artist names to prevent duplicate data with low false-positive rate
