To humanize online identity by helping companies verify that their users are who they say they are.
Role
Who you are
- Experience - 5+ years of security software engineering experience at a fast-moving technology company, including experience with building performant, highly interactive web applications
- Passion for security - You should be excited about keeping your skills and knowledge sharp, and sharing that with your peers and the rest of the company
- Product-thinker - You build products in a way that maximizes product value while minimizing complexity. You understand and can resolve tensions between product requirements and engineering design for large-scale projects
- Innovative mindset - You go beyond implementing what is asked and make product suggestions and features that help push our product forward. You are naturally curious and embrace change
- Proactive thinking - You learn from your mistakes quickly, and know how to unblock yourself when needed. We’re looking for someone that can tell us how to solve our problems, instead of waiting to be told how to solve problems
- Collaborative spirit - You work well across teams and are comfortable learning new areas
What the job involves
- The Persona Security Team is looking for a Ruby on Rails software engineer to help shape how highly sensitive identity and PII data is protected as our platform grows and evolves
- As a platform built from and built for individual identities, security is not a layer we add later – it is core to our identity and embedded in everything we build
- In this role, you will help ensure that businesses and their users can rely on Persona to verify identity, access critical services, and protect sensitive data
- You will shape and build the security building blocks that engineering teams build on top of to protect customer accounts and identity data
- Own the security foundations that safeguard sensitive identity data at scale and protect the trust our customers place in Persona
- Design and build IAM systems that Persona's enterprise customers use to manage PII across global teams and departments
- Partner with engineering teams across Persona to prevent or eliminate complex multi-product vulnerabilities
Our take
Persona enables businesses to verify customer identities, fostering trust in online interactions and aiding in age verification, fraud prevention and account recovery. It offers a comprehensive suite of automated identity verification components with worldwide coverage that can be configured, branded and themed to create custom-tailored flows for any use case.
Businesses and governmental organizations can access Persona’s platform via an API, which supports various documents from government-issued IDs to biometrics, ensuring customers are who they claim to be. Persona’s platform also collects passive signals such as a user’s device, location and behavioural patterns to provide a more holistic risk profile, beneficial in financial and insurance contexts.
An impressive partnership with MDT saw Persona enable credit unions to adjust their identity verification flows in real-time, strengthening fraud prevention. The company continues to attract funding which supports the scaling of its offerings and reach. In fact, in 2025, it reached a $2 billion valuation, which showcases the success it has had.
