Remote Linux Kernel Development Jobs in San Francisco, CA

Lilitab/GCX is building next-generation IoT fleet management software for medical carts and connected healthcare devices used in hospitals nationwide. We’re looking for a Software Engineer who thrives across the full stack—from Linux-based device clients to modern cloud platforms.

In this role, you’ll design and build systems that connect physical hardware to cloud services, enabling healthcare organizations to provision, monitor, and manage thousands of devices at scale. You’ll work on a small, highly collaborative team with significant ownership and direct impact on product direction.

This is a hands-on engineering role, not a maintenance position—you’ll be building new features, shaping architecture, and helping unify multiple platforms into a single, scalable system.

• Build Linux-based client applications that bridge hardware peripherals to cloud services (e.g., serial, HID, system interfaces)
• Develop webview-based device UIs with JavaScript-to-native/system integrations
• Design and implement Spring Boot REST APIs and React-based frontends
• Create and enhance web-based admin interfaces for provisioning, monitoring, configuration, and analytics
• Extend and maintain an existing Java/Jersey-based fleet management portal
• Support and evolve a Python/Django IoT platform
• Implement API proxy and composition patterns to integrate legacy and modern systems
• Design and optimize PostgreSQL schemas, including hierarchical data models
• Work with AWS cloud services, including IoT Core, Greengrass, ECS, S3, Lambda, and Cognito
• Build and deploy containerized applications using Docker and CI/CD pipelines
• Contribute to system integration design between embedded devices and cloud platforms
• Troubleshoot and resolve complex production issues
• Document technical designs, APIs, and operational processes
• Collaborate on architecture, code reviews, and engineering best practices

• 7–15 years of software engineering experience
• Must reside within a 50-mile radius of Petaluma, CA
• Must be authorized to work in the United States
• Strong experience building IoT or hardware-adjacent applications on Linux systems
• Proficiency with:
  • Java (Spring Boot, REST APIs, Maven)
  • Python/Django
  • React (hooks, state management, component architecture)
• Solid Linux systems experience (CLI, system-level debugging)
• Experience with PostgreSQL (schema design, query optimization, migrations) and familiarity with MySQL
• Hands-on experience with AWS services (ECS, S3, Lambda, Cognito)
• Experience with Docker and containerized deployments
• Familiarity with CI/CD pipelines (GitHub Actions or similar)
• Strong understanding of REST API design and documentation (OpenAPI/Swagger)
• Experience working across multiple layers of the stack

• Experience with AWS IoT (IoT Core, Greengrass, edge computing)
• Additional backend experience (e.g., Node.js/Express)
• Modern Java experience (Spring Boot 3.x, Java 17+ / 21)
• Experience with IoT device provisioning, telemetry, or fleet management systems
• Familiarity with time-series data systems (e.g., Timestream, Kinesis)
• Knowledge of OAuth2 / OpenID Connect / Cognito
• Experience migrating or consolidating legacy systems
• Background working with inherited or contractor-built codebases
• Experience in healthcare, medical devices, or regulated environments
• Exposure to iOS/iPad application development

GCX/Lilitab designs and manufactures medical carts and mounting solutions used in healthcare environments across the U.S. Our software team is building IoT solutions that bring these devices online—enabling real-time monitoring, remote management, and operational insights.

You’ll join a small, high-impact team (3–4 engineers) working across:

• A Java-based tablet/peripheral management platform
• A Python-based IoT system for medical carts

You’ll play a key role in evolving these into a unified fleet management platform.

• You take ownership of features end-to-end, from design to deployment
• You’re comfortable navigating and improving complex, mixed-technology systems
• You contribute to a growing engineering culture with strong standards and practices
• You can quickly understand and extend unfamiliar codebases

• Cloud Architecture (AWS)
• IoT amp; Edge Computing
• REST API Design
• Java / Spring Boot Development
• React Frontend Development
• Database Design amp; Optimization
• Containerization amp; Deployment (Docker, ECS)
• System Migration amp; Platform Consolidation
• Software Development Lifecycle (SDLC)
• Testing amp; CI/CD
• Version Control (Git)

• Build software that directly impacts healthcare delivery
• Work on real-world IoT systems connecting hardware and cloud
• High ownership in a small, fast-moving team
• Opportunity to shape architecture and engineering practices
• Be part of a major platform transformation
