Senior Software Engineer - Client Platform

About Quizlet:

At Quizlet, our mission is to help every learner achieve their outcomes in the most effective and delightful way. We’re a $1B+ learning platform used by two-thirds of U.S. high school students and half of college students, powering over 1 billion learning interactions each week.

We blend cognitive science with machine learning to personalize and enhance the learning experience for students, professionals, and lifelong learners alike. We’re energized by the potential to power more learners through multiple approaches and various tools.

Join us to design and deliver AI‑powered learning tools that scale across the world and unlock human potential.

Quizlet is right in the middle of transforming our tech stack from thick, “smart” clients to a world of thin, server‑driven clients that are powered by our AI systems. To achieve consistent patterns and move quickly, we are building a Client Platform team focused on solving tech problems shared across our Mobile and Web clients (and potentially others in the future).

Some things that might fall into your remit include the following: uplevel our client analytics logging and feature flagging systems, standardizing (and building the systems to support) deep linking to experiences and content across our platforms and services, and building mechanisms and tooling that will allow us to test our experiences end‑to‑end and across platforms and marketplaces.

As a new team without a firmly defined charter, you will have a big say in what the day‑to‑day of this position looks like. That said, this role will be expected to partner closely with leads across our Mobile, Web, Backend, and Platform teams as well as Product and Engineering leadership.

On a daily basis, you will identify areas where the Client Platform team can drive solutions and partner with your leadership, as well as cross‑team and functional partners to define what a solution entails. Additionally, you will roadmap and deliver that work to your team and others. This work will be highly ambiguous, requiring collaboration across our tech stack and influencing others within the company.

We’re happy to share that this is an onsite position in our London office. To help foster team collaboration, we require that employees be in the office a minimum of three days per week:
Monday, Wednesday, and Thursday and as needed by your manager or the company. We believe that this working environment facilitates increased work efficiency, team partnership, and supports growth as an employee and organization.
