Build the future of
cold email infrastructure

We're a small, remote team solving hard problems in email deliverability, SMTP infrastructure, and developer tooling. If you're passionate about building reliable systems at scale, we'd love to hear from you.

Small team, big impact. Every person at Winnr directly shapes the product and the company.

Fully Remote

High Ownership

No layers of approval. You own your domain end-to-end and ship directly to production. Move fast and take responsibility.

Competitive Comp

Competitive salary plus equity. We're early-stage and growing fast — early employees have significant upside.
