Fellow Engineer Jobs in California (NOW HIRING)

At Fellow, we're on a mission to help people brew ridiculously good coffee at home. But we're more than just beautifully designed kettles and grinders-we're a brand built on innovation, community, and culture. We believe great coffee isn't just about the final cup; it's about the experience, the ritual, and the people who make it all happen.

We're looking for an Automation Engineer (CI/CD, Firmware, Mobile, Backend) to support hardware product development and testing. 

This role is based in our office in San Francisco, CA and is required to be in-office 4 days per week. 

We are seeking a highly skilled Automation Engineer to design, build, and maintain end-to-end CI/CD pipelines that automate testing, deployment, and release workflows across software, firmware, mobile applications, and AWS-based backend services. This role requires deep experience in test automation, hardware-integrated testing, and the ability to work with system logs and external measurement devices. You will also play a key role in enabling intelligent debugging by integrating test outputs with AI-based analysis tools.

CI/CD & Automation Frameworks

• Design and implement scalable CI/CD pipelines to automate build, test, deployment, and release processes for:
• Embedded firmware
• Mobile applications
• Cloud-based backend services (AWS)
• Maintain and optimize automation frameworks to support continuous integration and delivery across multiple platforms.
• Firmware Automation
• Implement automated workflows to:
• Enforce coding style and static analysis checks
• Execute unit tests
• Compile firmware codebases from GitHub
• Flash firmware onto physical devices
• Run automated functional and integration test cases
• Collect, normalize, and forward device logs and test results to AI agents for debugging and root-cause analysis

Mobile Application Automation

• Build automated pipelines to:
• Perform coding style and lint checks
• Run unit tests
• Deploy builds from GitHub to test environments
• Install applications on physical test phones
• Execute automated UI and functional test cases
• Aggregate logs and test artifacts and pass them to AI agents for debugging

Backend Automation (AWS)

• Develop automation to:
• Enforce coding standards and static analysis
• Run unit and integration tests
• Deploy services from GitHub to test environments
• Execute automated backend test suites
• Capture logs, metrics, and traces and forward them to AI agents for intelligent analysis

Hardware & Data Integration

• Design and maintain automated tests that integrate:
• Hardware device logs
• Data from external measurement devices such as sensors, scales, or other instrumentation
• Ensure reliable data capture, synchronization, and validation across hardware and software systems.

• Bachelor's degree in Computer Engineering, Electrical Engineering, Computer Science, or a related field (or equivalent practical experience)
• 7+ years of experience in test automation, CI/CD, or automation engineering roles
• Proficiency in automation scripting (Python or similar)
• Hands-on experience with hardware-integrated automation testing
• Strong experience designing and maintaining CI/CD pipelines (e.g., GitHub Actions, GitLab CI, Jenkins, CircleCI)
• Strong debugging and problem-solving skills in complex, multi-system environments
• Proven experience with hardware automation, including tests that integrate machine logs and data from external measurement devices such as sensors and scales
• Familiarity with Git-based workflows and version control best practices
• Ability to design robust, repeatable, and scalable test automation systems
• Expertise in log collection, processing, and analysis

Preferred Skills & Experience

• Demonstrated experience working across firmware, mobile, and backend systems
• Familiarity with embedded systems, RTOS, or low-level firmware development
• Experience with mobile automation frameworks (e.g., Appium, XCTest, Espresso)
• Experience with cloud-native testing, observability, and monitoring tools
• Knowledge of containerization and orchestration (Docker, Kubernetes)
• Experience working in IoT, consumer electronics, or hardware-software integrated products
• Experience integrating automation outputs with AI or ML-based debugging/analysis tools
• Experience with firmware build systems, flashing tools, and device communication
• Hands-on experience automating mobile application testing on real devices
• Strong understanding of AWS-based backend services and deployment workflows
• Experience with test frameworks for unit, integration, and system testing

Salary Range: $165,000- $185,000
