Assembling a top notch team is the #1 challenge forward-looking companies know they must solve. At Lever, we’re building next-generation collaboration software that helps companies bring more transparency, participation, and engagement to their hiring. As an Infrastructure Engineer, you’ll help us keep Lever ahead of customer growth by making a continual scaling improvements to the underlying infrastructure and help our product engineering team move quickly with confidence.
As Lever’s Infrastructure Engineer, you'll be automating all the things: application and infrastructure deployment, continuous integration, monitoring, and alerting. You’ll also own deployment and operation of Lever’s product systems and services. You’ll lead the design and development of tooling, automation, and dev processes for operating a fast-growing SaaS business. You'll also address the unique operational challenges of a real-time web application.
Help us mitigate risk while increasing reliability. We’ll trust you to lead our ability to triage and deal with operational issues. Advise our team on how to write code and architect systems that make our entire codebase more testable, scalable, and dependable. Introduce tools and practices to improve our deployment and testing. Own our disaster planning and socialize the monitoring and on-call procedures that will help our entire engineering team support you.
You’ll join a team where everyone—including you—is striving to constantly improve their knowledge of infrastructure, systems, and cares about minimizing downtime. We are an incredibly supportive team–we love to pitch in when problems arise and give great peer feedback to help each other grow. We are passionate about lots of things--automation, friendly chat bots, creating a great hiring experience, and a great user experience--and we love sharing those passions with each other.
Lever uses our own open source MVC framework called Derby that syncs all data via Operational Transformation (the algorithm behind Google Docs and Wave). OT is the way we handle concurrency conflicts for any piece of data that is edited at the same time. In addition to real-time sync, OT allows us to provide a smoother UI since we can render updates on the client instantly without waiting for our backend to respond, while still guaranteeing consistency. For a more in-depth look at OT, here's a conference talk
that Nate, our CTO, gave!
Lever makes extensive use of AWS, Docker, Node, Mongo, ElasticSearch, and Redis within our infrastructure. We use tools like Hubot to streamline deployments and Graphana to see what’s going on under the hood. In addition to automating all the things, we love to version them too! Our systems are all created using Terraform and Chef, working together to ensure consistency at all costs.

THE LEVER STORY
Lever builds modern recruiting software for teams to source, interview, and hire top talent. Our team strives to set a new bar for enterprise software with modern, well-designed, real-time apps.

Under the hood, we're a technology company with a powerful open-source web framework: DerbyJS
. It is the first and only open-source MVC framework that syncs all data via an Operational Transformation backend
, using the same algorithm that powers Google Docs. DerbyJS is also uniquely optimized to render everything on the server as well as the client.
