Web Engineer

In the initial months, you’ll work closely with the team on the surfaces that bring new people into our products, gradually taking ownership of a growing part of our consumer web experience. Given our stage, we’re seeking versatile engineers comfortable working across product, engineering and growth., Designing and maintaining our event tracking taxonomy (Amplitude) so that the data is consistent, well organized and trusted across teams. You’ll instrument funnels end-to-end, run rigorous A/B tests, and turn the results into decisions.

Growth Initiatives

Identifying and shipping new ways to improve acquisition and conversion. We expect you to look at the funnel, form your own hypotheses, build, measure, and then either scale or drop the idea. You’ll be an active contributor to the roadmap, not just its executor.

Owning your scope

You’ll be responsible for the architecture, performance, monitoring and reliability of everything you ship. We value engineers who take full ownership of their scope, and who proactively address issues before anyone asks., We’re looking for exceptional engineers, and we set the bar high on purpose. In return, you’ll get real ownership of a high-impact surface, products used by millions of people, a team that ships in days rather than quarters, a modern stack with top-tier tooling, and colleagues who will push you to grow.

We are hiring multiple engineers of varying levels, so please indicate your years of experience on the application form to apply for the appropriate position.

5+ years of professional experience building consumer-facing web products.

Strong understanding of web performance: rendering strategies (SSR, edge, static), caching, CDNs, Core Web Vitals, and how mobile and in-app browsers behave.

Hands-on experience with deep linking, Universal Links / App Links and attribution. Experience with App Clips is a big plus.

Experience designing analytics taxonomies and running experiments, and real care for data quality.

Comfortable working autonomously across frontend and backend. Knowledge of infrastructure (Bazel, GCP, Kubernetes) is a plus.
