**About Persona** [Persona](https://withpersona.com/) 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.

We’re growing rapidly and looking for exceptional people to join us! ### About the role 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. ### What you'll do at Persona - **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. ### What you'll bring to Persona - **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. **Benefits and Perks** For full-time US-based 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.
