Engineering at Klaviyo
Klaviyo is a Boston startup located right in the heart of downtown Boston. We craft software helping thousands of ecommerce companies to have engaging relationships with hundreds of millions of consumers. We love tackling 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.
Klaviyo operates a real-time data platform coded in Python built for massive scale on Amazon Web Services (AWS). Engineers come to Klaviyo with experience in a variety of languages and from a number of disciplines.
What you’ll be doing:
- Have the chance to wholly own features that thousands of our customers rely on daily to reach 100,000,000+ of consumers to drive their business forward
- Work on crafting our highly scalable real-time data pipeline that processes billions of events monthly across data sets growing to petabyte scale
- Be empowered to own the mission, technical direction and operations of projects that have immediate impact
- Advance your technical skills in all facets ranging from front end web development and user experience to machine learning and massively parallelized data pipelines
- Contribute 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
We’d love to hear from you if you:
- Have experience building products that matter and pushing yourself and your team to be better engineers and build a product with passionate advocates
- Enjoy working with new technologies ranging from the frontend to backend, and are particularly passionate and an expert in multiple stack areas. You show this by having strong and opinionated experience with various technologies and know how to pick the right tool for any job
- 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
