About The Position

Your mission is to 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.

Requirements

• 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.
• Pragmatic speed. You ship a solid v1 today rather than waiting for a perfect v2 next month. You actively avoid over-engineering and have a strong instinct for the right level of investment at each stage.
• Full-stack flexibility. You're comfortable in the backend APIs and services that power the mobile experience, not just the UI layer.
• Data operations literacy. You understand data pipelines, quality standards, and delivery workflows well enough to provide meaningful technical oversight, even where execution is handled by partners or specialists.

Nice To Haves

• Prior startup experience building in early-stage environments where you had to balance speed with the stability a consumer app demands.
• Familiarity with audio data pipelines, WebRTC-based recording architectures, or dataset delivery workflows for AI training.
• Telecom or CPaaS background with a deep understanding of global communications infrastructure.
• International experience building apps for non-US markets, including fragmentation, localization, and varying network conditions.

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.
