Role
Who you are
- If you're passionate about working on large-scale, complex systems that make a difference, this is the place for you
- Have 8+ years of experience in a software engineering discipline and have architected, built and delivered at least one complex system
- Have profound experience/understanding on large-scale system architecture, technologies and patterns. Have deep insights of their pros/cons and use scenarios, able to apply them to system design by making appropriate tradeoffs to meet the business needs best
- Love digging into performance and scalability issues to drive breakthrough solutions-- whether it's a performance degradation 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
- Passionate about growing and improving a product daily using a data driven mindset, familiar with system monitoring and alerting techniques
- Proven experience with being a coach and a mentor for team members and helping them grow
- Like working on small, high-performing autonomous agile teams. At Klaviyo, you will have ownership of features, but you'll collaborate radically with everyone to make sure we produce the right solution
- Based on Boston and willing to meet with the team in the office regularly
- Bachelors degree in Computer Science or equivalent experience

- Every day, our systems power the scheduling and processing of tens of thousands of campaigns, delivering over 1 billion messages
- We empower our customers to target diverse audiences effectively, all while ensuring compliance with industry standards and best practices
- In this role, you will own and build features/services that hundreds of thousands of Klaviyo customers rely on daily to drive their business forward
- Work on crafting our highly-scalable, highly-available sending pipeline that processes and delivers 1B+ messages daily
- Collaborate radically with teams and stakeholders across Klaviyo on designs, implementations, and engineering practices
- Learn new technologies, bring them to the team and apply them to evolve our systems to the next level
- Help us improve our experimentation and development processes, and mentor other engineers on the team

- Contribute to the company as a subject matter expert, constantly pushing yourself to be a better engineer and to level up all of your peers within your team and within Klaviyo
Our take
Klaviyo is a marketing firm helping growth-focused eCommerce brands drive more sales with super-targeted, highly relevant email, Facebook and Instagram marketing campaigns. From personalised newsletters to automated emails when customers abandon their shopping carts, the marketing automation platform makes it easy for businesses to capture, store, analyze, and predictively use their own data to drive measurable, high-value outcomes.
Klaviyo's CEO, Bialecki, believes that the main problem with e-mail marketing today is that there is a divide between two kinds of tools: analytics tools that help you understand what people are doing on a website, such as what products they are considering, and messaging tools that send them a marketing e-mail. Operating primarily within the retail and eCommerce industry, Klaviyo aims to solve this by offering a tool that brings together analytics and messaging. This allows companies to bring all of their first-party data into a single platform to get a deep understanding of their customers and then activate that data to deliver highly-targeted, personalised communications through email and SMS. In the process, Klaviyo's customers get a deep understanding of their consumers.
Klaviyo is a fast-growing company mainly due to its business model - the firm offers a concrete ROI for Klaviyo’s clients if the software persuades customers to make purchases by treating different types of customers differently. An IPO in 2023 has led to Klaviyo's release of Klaviyo AI, which empowers businesses to unlock revenue-driving opportunities and deliver exceptional customer experiences across channels. Still in its early days of public listing, it will be interesting to see how Klaviyo fares in the years to come.
