Lead Software Engineer - Internationalisation

Klaviyo is growing by leaps and bounds; as a result, we’ve recently established our Internationalisation team!

The Internationalisation team focuses on enabling every engineer at Klaviyo to write, test, and deploy frontend code as efficiently and easily as possible. While other teams are focused on shipping specific product features to Klaviyo customers, we focus on the underlying infrastructure they use and frontend problems that impact Klaviyo as a whole.

This particular role is an opportunity to establish the foundation for how we will internationalise our product. You’ll help lead our internationalisation strategy, tooling and approach within engineering.  This is a unique opportunity with many personal and leadership growth opportunities.

We are looking to learn from you and leverage your past experience successfully driving or contributing to the internationalisation of a complex SaaS product in a multi team environment.

How you will make a difference:

• Design, build, and maintain a robust frontend system to make internationalisation integrated throughout the software development lifecycle. The code you write will help empower an organisation of 100+ engineers (and counting) ship frontend changes faster and more safely.
• Mentor the engineering team at large on how to write frontend code effectively, with a focus on internationalisation patterns.

Who You Are:

• An experienced engineer who has successfully internationalised a complex SaaS product using React.
• 2+ years of professional experience with React.
• Strong knowledge of vanilla JS, ES2015+ syntax, and the Javascript ecosystem as a whole.
• Familiar with HTML, CSS, and general web best practices.
• Comfortable working across different parts of a large codebase.
• Highly collaborative and communicative.

Bonus points for:

• Experience with Typescript.
• Experience with custom frontend build systems + tooling (e.g. Webpack, Babel, TypeScript, ESLint, Jest, Jenkins, CDNs, etc.).
• Developing application APIs (e.g. REST, GraphQL, JSON Schema, or JSON:API, etc).
• Having established best practices in how a company writes, tests, and deploys frontend code.
• Constantly thinking about frontend performance. If shaving kilobytes off a JS bundle or fixing wasted renders sounds appealing, we want to hear from you.
• Authorisation to work in the UK without restriction.

Klaviyo in EMEA;

London was our first non-US location for Klaviyo, opening up in 2019 and growing since then to a large team of people with teams across Sales, Customer Success, Marketing, Services, Partnerships, IT and HR. Collectively in EMEA we are contributing a significant part of Klaviyo’s overall global success, growth to date and opportunity that lies ahead. The good news is that we are still at a stage where everyone coming into the business has the opportunity to make a real tangible impact that you will be able to see and feel.

We are proud of everything we have built here in EMEA, a vibrant diverse team embracing hybrid working in line with the way the world of work has changed. When Klaviyos do travel to the office you’ll be able to use your monthly commuter allowance if you need it. Once here you'll be able to enjoy the comforts of an incredible environment with all the perks we love and you’d expect such as, free snacks / drinks, a peloton studio and a roof terrace overlooking the city to rival anything you’d find in London as well as regular team celebrations and company lunches.
