Software Engineer, Edge

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 have built Persona to support practically every use case and industry - that’s why we are 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 are 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 have grown, that became the wrong tradeoff, and we fixed it by giving networking its own home, its own roadmap, and its own definition of done.

This team owns the full traffic 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 will be one of the first engineers on a team with a clear, narrow mission and real ownership. You will help define what good looks like for a traffic layer that Personas 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 will do at Persona

Own edge networking configuration: routing, WAF policy, rate limiting, certificate management, driving toward a model where engineers ship traffic changes without waiting on infra. We use Cloudflare extensively but not exclusively.

Evolve the ingress layer (controllers, lifecycle, policy, Ingress API) so inbound traffic is reliable, observable, and self-service

Manage DNS across internal clusters and external zones so name resolution is invisible by design

Build network-layer observability: latency, error rates, routing visibility that surfaces problems before they become incidents

Support Personas regional expansion by extending networking into new geographies and ensuring regional expansion is scalable, performant, and maintainable

Help define the teams practices and technical standards. This team is new, and you will 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 will 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

Experience diagnosing production issues at the network layer, including understanding how proxies and load balancers can obscure the real source of a problem. You should enjoy deep, methodical investigatory work - but also have the chops to quickly take on triage and solutioning should an emergency arise

Kubernetes networking in practice: ingress controllers, DNS, network policies, not just running workloads

Manage infrastructure as code in practice, not just in principle. Change safety and governance should be a feature not a bug - and you enjoy designing those processes so they appear low-friction while having real teeth

Experience building internal platforms or tools with a track record of driving adoption across engineering teams. We love OSS and hope to continue contributing, but we also need to unblock ourselves today when external tools fall short.

Nice to haves

Cloudflare (Workers, WAF, Access, or Tunnel)

Istio or another service mesh in a multi-cluster environment

GKE or managed Kubernetes at scale

Ruby or Rails (we integrate with Ruby systems)

A hackers heart for prototyping new ideas and ways of operating - even though experimentation might not progress beyond the toy phase

Full-time Employee Benefits and Perks

For full-time employees (excluding internship and contractor opportunities), Persona offers a wide range of benefits, including medical, dental, and vision, 3% 401(k) contribution, unlimited PTO, quarterly mental health days, family planning benefits, professional development stipend, wellness benefits, among others. While we believe competitive compensation and benefits are a critical aspect of you deciding to join us, we do hope you consider why our core values and culture are right for you.
