Company mission
To humanize online identity by helping companies verify that their users are who they say they are.
Role
Who you are
- 5+ years building data-intensive products or backend/full-stack services, with a track record of shipping customer-facing products end to end
- Proficiency in a backend language (we use Python, Ruby on Rails, and Go) and comfort working across the stack to ship product features end to end
- Experience building user-facing products or APIs backed by large datasets, with care for performance, correctness, and security/PII handling
- Working familiarity with SQL and analytical data stores (e.g. Snowflake, ClickHouse)
- Experience leading product-engineering initiatives across teams and mentoring other engineers
- Comfort operating in ambiguity and partnering with product to shape strategy, not just execute it
- Excellent communication and collaboration skills, with a track record of working closely with product and design
- A passion for using data to build transformative customer experiences
- Nice to have: experience building AI/LLM-powered applications or agentic tooling; React; Google Cloud (GCP); semantic layers
What the job involves
- We are looking for passionate engineers who are excited to turn data into products customers love
- As a senior engineer on the Data Products team at Persona, you'll build the customer-facing surfaces of our data platform — the features and services that let customers and internal teams query, explore, export, and act on their data
- This is a data-leaning full-stack role focused on building data-intensive products: from in-dashboard SQL and bulk data exports, to AI-powered analytics, to the application layer of our data platform
- You'll own the technical direction of our customer-facing data products end to end — shaping what we build and how — and mentor the engineers building alongside you, collaborating closely with product, design, data science, and the rest of engineering
- Build and grow customer-facing data products — from in-dashboard SQL that lets customers query their own data, to custom and bulk data exports, to entirely new data-rich features
- Build AI-powered and agentic analytics tools — product features that let customers and internal teams ask questions of their data in natural language
- Build the backend services, APIs, and query layer that power these products over large, fast-moving datasets — letting teams and customers access high-volume data in real time
- Partner with product and design to translate customer and business needs into reliable, performant, data-intensive features
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.
