Software Engineer, Network

About Persona Persona is the configurable identity platform built for businesses in a digital-first world. Verifying individuals and organizations is harder — but more important — than ever, with AI enabling fraudsters to launch sophisticated accounts at scale and regulations evolving rapidly. We’ve built Persona to support practically every use case and industry — that’s why we’re able to serve a wide range of leading companies. For example, Reddit relies on Persona for age assurance and verification to comply with online safety regulations, protecting younger users while maintaining a seamless experience. Meanwhile, OpenAI relies on Persona to keep bad actors out, protecting one of the world’s most powerful AI platforms from large-scale abuse in a time when AI is reshaping the way we work and live. We’re growing rapidly and looking for exceptional people to join us! About the role & the team Every request Persona handles crosses our network before it touches any product code. Cloudflare, ingress, DNS, and the service mesh are not background infrastructure. They are the front door and backbone. When they work, nobody notices. When they break, everything breaks. The Edge team exists because networking kept losing the prioritization battle inside a broader infrastructure team. As we've grown, that became the wrong tradeoff, and we fixed it by giving networking its own home [... source excerpt omitted ...] affic path — from the first packet leaving clients through our through our (Cloudflare-backed) ingress and then onward across the service mesh — as a product, not a service desk. You'll be one of the first engineers on a team with a clear, narrow mission and real ownership. You'll help define what good looks like for a traffic layer that Persona's engineers can configure, observe, and extend without filing a ticket. The changes you make to improve performance will result in meaningful client outcomes. What you'll do at Persona Own edge networking configuration: routing, WAF policy, rate limiting, certificate management, driving toward a model where engineers ship traffic cha [... source excerpt omitted ...] ing into new geographies and ensuring regional expansion is scalable, performant, and maintainable Help define the team's practices and technical standards. This team is new, and you'll shape what it looks like — from SDLC, usage of AI tooling, static analysis, chaos engineering, and usage of simulation. We are serious about encoding top-quality engineering practices into the team’s DNA — and you will be core to their development. What you'll bring to Persona Experience building and shipping production services in a polyglot environment (Go, TypeScript, or similar). You should enjoy the pros/cons of different languages — a zealot is unlikely to enjoy working in our garden E
