Klaviyo is a Boston startup located right in the heart of downtown Boston. We craft software helping thousands of e-commerce companies to have engaging relationships with hundreds of millions of consumers. We love taking on tough engineering problems and look for full-stack engineers who specialize in certain areas but are passionate about building, owning & scaling features end to end from scratch and breaking through any obstacle or technical challenge in their way. We push each other to move out of our comfort zone, learn new technologies and work hard to ensure each day is better than the last.

- Wholly owning features that thousands of our customers rely on daily to reach 100,000,000+ of consumers to drive their business forward.
- Working on crafting our highly scalable real-time data pipeline that processes billions of events weekly across data sets growing to petabyte scale.
- Working on a deep analytics system that provides insight into hundreds of terabytes of data.
- Be responsible for the mission, technical direction, and operations of projects that have an immediate impact.
- Helping architect and design robust and high-performance data processing and storage systems leveraging new databases to serve different internal and external use cases. Contribute to open-source data processing technologies.
- Contributing to the company as a subject matter expert in multiple areas, constantly pushing yourself to be a better engineer and to level up all of your peers within your team and within Klaviyo.

- Love digging into performance and scalability issues to drive breakthrough solutions-- whether it's a slow loading UI or too many clicks in a workflow, a database query timing out, or a queue that just won't drain. You recognize all problems can be solved
- Enjoy shipping code early & often in an agile fashion, pairing with product management to craft better software by soliciting feedback from thousands of end-users
- Like working on small, autonomous agile teams. At Klaviyo, you will have ownership of features, but you'll collaborate with everyone to make sure we produce the right solution
