Stock Options:

at Proton, we all have the opportunity to be owners of the company. From day one, you have a real stake in what we're building. When Proton wins, you win.

We're a small, tool-agnostic team that owns the observability infrastructure behind Proton's services — the logs, metrics, traces, and alerts that keep systems running smoothly for the millions of users who trust us with their privacy.

We run on open-source stacks across Proton's on-premise data centers, and we dogfood heavily: we're our own first customers.

We favor simple, solid solutions over large engineering efforts, and we believe good systems emerge iteratively.

Design, deploy, and operate observability pipelines for logs, metrics, traces, and alerts across Proton's services using open-source technologies.

Partner with development and platform teams to ship practical alerting, dashboarding, and integration solutions that engineers actually rely on.

Build reusable templates and tooling that streamline onboarding, incident response, and analysis.
