Why You Should Join the Web Platform Team
The Web Platform team owns all the ways we build, ship, monitor, and test frontend code at Klaviyo. As a Senior Software Engineer on the team, you will be deeply involved in how we build, maintain, and improve our deployment processes, core frontend services, and overall frontend performance.
You can look forward to being a part of a highly technical team with significant domain expertise. We oversee a well organized monorepo that is leveraged across the organization that deploys 50+ times a day. The team also owns and orchestrates a GraphQL backend for frontend service to offer strong end-to-end typing across our stack.
As we look toward the next 6-12 months, we aim to focus on improved developer velocity through improved static analysis and CI structure as well as better platform web vitals by overhauling our application initialization process.
How You Will Make a Difference:
- You will collaborate closely with other Web Platform team members to help build a best in class platform for our end customers and engineers.
- You will be responsible for implementing new functionality into complex frontend systems.
- You will help ensure our frontend is stable and secure by keeping core dependencies (eg. React) up to date.
- You will help educate other Klaviyo engineers on frontend best practices by attending RFCs, reviewing PRs, and holding office hours.
- You will be an active participant in all team processes including standups, groomings, retros, on call, and more.
- You will help interview new engineering team members as we continue to grow our organization.
