About Neon

Many large companies make billions each year by monetizing Americans’ personal data. At Neon, we’re finally cutting consumers in on the deal. Neon allows our users to make hundreds (or even thousands) of dollars per year by securely selling their anonymized data. We’re backed by Lightspeed, Upper90, Upfront Ventures, and other cool investors.

About the role

Your mission is to help build and own the technical foundation that powers Neon's consumer product and data business. This is a unique opportunity to be one of the first engineers on the team, working directly with the founder to shape both the product and the company. The ideal candidate is hands-on, entrepreneurial, and comfortable moving quickly in an environment where decisions have a direct impact on the future of the business. You'll partner closely with our Head of Mobile Product.

We're a small, early-stage team moving fast. Expect roughly 60 hours per week, with occasional weekend work around launches and deadlines. We're upfront about this because we'd rather find people who are energized by that pace than surprise anyone after they join.

Key Responsibilities:

• Design, build, and maintain customer-facing mobile applications using React Native (JavaScript/TypeScript) or native iOS/Android (SwiftUI, Objective-C, Kotlin).
• Architect, deploy, and manage cloud infrastructure (AWS, GCP, or Azure) to support growth and reliability.
• Own architectural decisions across system design, including scalability, security, and fault tolerance.
• Work across the full stack, contributing to our customer-facing mobile apps (React Native, or native iOS/Android) as the product requires.
• Build and provide technical oversight for the data pipelines and delivery workflows at the heart of Neon's data business.
• Establish engineering best practices, including testing, CI/CD, and monitoring.
• Collaborate closely with the founding team on product direction, roadmap, and customer feedback.
• Take ownership of projects end-to-end, balancing speed of execution with technical excellence.

You have…

• Authorization to work in the US.
• Hands-on engineering depth. You're a builder first. You write production code daily, make the big architectural calls, and implement them yourself. A small team means no room for pure management.
• VoIP and real-time communications expertise. You've implemented VoIP, SIP, or WebRTC in a real product and know the messy reality of call quality, carrier constraints, and latency at scale.
• Deep mobile experience. 4+ years building and releasing consumer mobile apps on iOS and Android, with significant experience in cross-platform development and React Native.
• Native mobile proficiency. Meaningful hands-on experience with Swift, Kotlin, Java, or Objective-C.
