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.

Weve built Persona to support practically every use case and industry thats why were 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 worlds most powerful AI platforms from large-scale abuse in a time when AI is reshaping the way we work and live.

Were growing rapidly and looking for exceptional people to join us!

About the role

The Compute teams mission: any engineer, using AI, should be able to stand up and operate a stateful service at production scale with no meaningful infrastructure knowledge required. We build the tiering zones, guardrails, and AI skills that make this possible. Reliable, observable, and self-service by design.

This is a software engineering role. Youll spend real time writing code: platform APIs, internal tooling, deployment pipelines, automation that replaces the support tickets. Infrastructure fluency matters; infrastructure specialization is not the lead. What matters most is product instinct: understanding your users (product engineers), measuring whether theyre getting unblocked, and treating developer experience as a feature acceptance criterion.

The platform is yours to own, not just build. When ArgoCD fails and every teams deploy is blocked, thats your page. When a product engineer cant figure out why their service is OOMKilling and theres no useful error surface, thats your design failure to fix.

A Senior engineer will help define the platforms interfaces and own how product teams interact with compute infrastructure. The team is still establishing its patterns, and youll have real influence over what they become.

What youll do at Persona

  • Build internal platform tooling and APIs that product engineers use to deploy, scale, and observe services, with developer experience as a first-class requirement

  • Own and evolve the Kubernetes platform, ArgoCD deployment pipeline, and Terraform IaC that underpin every service at Persona

  • Improve platform observability so "why is my service slow" and "why did my deploy fail" have self-service answers. Instrumentation is a platform primitive, not a per-service afterthought.

  • Drive Cloud Run-to-Kubernetes migration, working directly with product teams to remove blockers and hand off operational ownership cleanly

  • Design self-service workflows to reduce the Compute interrupt load. Success means product engineers can do more without filing a ticket.

  • Define the interfaces and abstractions the platform exposes to product teams. What does "easy to use correctly" look like for a deployment workflow or platform API?

What youll bring to Persona

  • Strong SWE fundamentals: shipped production services, writes readable and operable code, can debug distributed system failures across layers you dont fully own

  • Product instinct: you measure adoption, treat low usage as a design failure, and change things based on user feedback rather than your own assumptions

  • Developer experience sensibility: you identify friction in CLIs, APIs, and deployment workflows and design for clear affordances, actionable error states, and progressive disclosure

  • Kubernetes in practice: youve operated services on K8s, can debug scheduling failures, write RBAC policies, and work out why a pod wont start. Youre willing to be paged for the platform you build.

  • Infrastructure as code in a team context: youve modified production IaC alongside other engineers and understand why declarative infrastructure and change safety matter

  • Senior candidates: we look for production-level Terraform ownership, including state, module composition, and clean infrastructure refactors.

Nice to haves

  • Deep K8s internals: cluster lifecycle, admission controllers, custom controllers/operators

  • ArgoCD or another GitOps tool in production

  • GKE or managed Kubernetes at scale

  • Ruby or Rails (we integrate with Ruby systems)

  • Experience in a regulated or high-trust environment

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.
