Distributed Systems Engineer

We founded Lever in 2012 to tackle the most strategic challenge that companies face: how to grow their teams. We're injecting the values we respect – collaboration, transparency, and humanity – into our software and re-imagining how organizations can think about growth, with talent and teamwork at the center.

Drive scalability and performance of a cutting-edge, real-time platform. Work directly with our CTO on a small team of experienced engineers. Our team develops ShareDB, a distributed realtime application backend. ShareDB syncs all data via Operational Transformation, the same algorithm that powers Google Docs. We are also responsible for scaling pub/sub messaging, ElasticSearch, taskqueues, realtime email sync, data apis, reporting infrastructure, and frontend Node.js applications. Guide us in making calls on performance tradeoffs, when to hack and when to invest, how to choose the right level of abstraction, how to design systems that both work well and fail well. And know that all the work that you do the team at Lever will enrich the open source community.
