About The Position

We're looking for a Staff/Lead Full Stack Software Engineer to own BrakeWise — our production brake inspection application — along with the customer dashboard it feeds. BrakeWise is in the field today, shipping to iOS through the Apple App Store and to Android and Windows through Expo, and technicians rely on it during live service work. This is not a greenfield build: you'll be taking ownership of a product that already has customers, and growing it. You'll own both surfaces end to end. On mobile, that's the React Native app, its hardware integrations, and every release that reaches a device. On web, that's the React/Bun.js customer dashboard and the GCP services behind it. The person in this role sets the technical direction for both, and is accountable for what production looks like on a Tuesday afternoon in a busy shop. This is a hands-on technical leadership role. You'll write code daily, make architectural decisions that shape the product's trajectory, and mentor a growing engineering team. Because the product is already in customers' hands, release discipline, observability, and upgrade paths matter as much as new features.

Requirements

8+ years of professional software development experience, with deep React and React Native expertise
Demonstrated experience owning mobile and web deployments end to end for thousands of users — app store releases, OTA updates, and web deploys, including the failures
Production experience shipping and maintaining cross-platform React Native applications, ideally with Expo
Strong background in cloud platform architecture, preferably GCP — Cloud Functions, Firebase, Cloud SQL, and Docker
Proven experience in system architecture, API design, and hands-on implementation
Experience with CI/CD pipelines and automation tools (e.g., GitHub Actions, EAS Build, Jenkins)
Experience with database technologies (SQL, NoSQL) and messaging systems (queues, pub/sub)
Track record of operating and supporting a live product, not just launching one
Strong understanding of software engineering principles including SOLID, clean code, and test-driven development
Excellent problem-solving, debugging, and communication skills

Nice To Haves

Experience with Bun.js or other modern JavaScript runtimes in production
Experience with on-device image processing, camera integration, or computer vision in mobile apps
Experience integrating USB or Bluetooth peripherals with mobile applications
Background in offline-first mobile architectures and data synchronization patterns
Experience with robotics, IoT, or edge computing (ROS or similar platforms)
Familiarity with automotive service, dealership operations, or DMS ecosystems
Contributions to open-source projects

Responsibilities

Own BrakeWise end to end — architecture, feature development, release management, and production support across iOS, Android, and Windows
Own the React/Bun.js customer dashboard, from interface through to the services behind it
Run the full deployment lifecycle for both surfaces: App Store submission and review, Expo/EAS builds and OTA updates, staged rollouts, versioning, and rollback
Own the web deployment stack on GCP — Cloud Functions, Firebase, Cloud SQL, and containerized services
Design and maintain the cloud backend that ingests, processes, and stores inspection data (images, measurements, structured results)
Develop and consume RESTful APIs and integration layers between the mobile app, dashboard, cloud services, and internal systems
Integrate the app with inspection hardware, including USB-connected cameras and sensors
Implement and manage databases, messaging systems, and data pipelines supporting real-time and batch inspection workflows
Own testing, CI/CD, monitoring, and alerting for a live product — and establish the practices that keep releases uneventful
Triage and resolve field issues reported by technicians and customers, debugging against real devices in real shop conditions
Mentor and guide engineers, fostering their growth and raising the team's technical bar
Collaborate with cross-functional teams including product, hardware, data science, and field operations
Proactively identify technical risks and architectural trade-offs, and communicate them clearly to leadership
