Job Description

At Klaviyo we value the unique backgrounds, experiences and perspectives each Klaviyo (we call ourselves Klaviyos) brings to our workplace each and every day. We believe everyone deserves a fair shot at success and appreciate the experiences each person brings beyond the traditional job requirements. If you’re a close but not exact match with the description, we hope you’ll still consider applying.

The Klaviyo Data Science team loves programming and the excitement that comes with building something people use. We are the kind of people that love talking to users and can find the balance between solving a problem quickly and thinking about how code will scale in the future. We love to move fast, keep learning, and get stuff done.
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.
The Ecosystem Intelligence team aims to help Klaviyo’s customers understand how well they are performing, pinpoint areas for improvement, and grow by implementing best practices.  We are responsible for building out robust ETL pipelines using technologies including Airflow and Celery.  We then surface this data through customer-facing features, like Benchmarks where users can compare their performance to their peers’ results and identify their biggest growth opportunities.
As a Software Engineer, you will be responsible for the ownership of key features within the ecosystem intelligence space, working alongside other experienced engineers. You will work directly with the team plus our product manager to help drive technical conclusions from stakeholders, as well as set our roadmap, team objectives, and goals.
How you will make a difference:

Build features built on data science that thousands of our customers rely on daily to reach 100M+ of consumers to drive their business forward
Ship code early & often in an agile fashion, pairing with product management to craft better software by soliciting feedback from thousands of end users
Be empowered to own the mission, technical direction and operations of projects that have immediate impact
Test data science algorithms and techniques on data sets and engineer data systems that let non-technical users make decisions with their first party data in real time
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

Who You Are:

2+ years of software engineering experience in a fast-paced SaaS environment
Enjoy working with new technologies ranging from the frontend to backend, and are particularly passionate and an expert in multiple stack areas
Passionate about working with Data Scientists in productizing data science / machine learning models for end-users, including building out the necessary back-end and UX/UI (Javascript, HTML, React)
Deep knowledge of object oriented programming and experience with at least one object oriented programming language (Python, C++, Java, C#, Ruby)
Experience with database technologies such as SQL, PL/SQL and relational database schema design in production
Experience with developing test strategies, designing automation frameworks, writing unit/functional tests to drive up code coverage and automation metrics
Have a bachelor’s or advanced degree in computer science, applied math, statistics or other relevant quantitative discipline, or equivalent industry experience.
