Software Engineer - Customer Integration

Sonatus, Pangyo, South Korea +1

The role

At Sonatus, we are redefining the future of Software-Defined Vehicles (SDV) through agility and innovation. To achieve this, we operate as Mission-Driven Squads, where each team takes full end-to-end ownership of a specific module to deliver production-ready software with speed and precision.

We are looking for a Software Engineer – Customer Integration to join one of our squads (e.g., Secure Network, Data Hub) as a core member. In this role, you will go beyond traditional coding; you will act as a Full-Cycle Engineer who ensures the quality and reliability of the features you build.

What you will do

Squad Mission Contribution
Work under the guidance of the Squad Lead to execute the full engineering lifecycle—from Implementation to Verification.
Switch roles flexibly based on the squad’s goals (e.g., focusing on feature development in one sprint, and shifting to verification tasks in the next) to ensure the mission is accomplished.
Cross-Functional Engineering (Hybrid Dev & QA)
Development: Design and develop high-quality C/C++ embedded software based on customer requirements.
Verification: Design Python-based test cases and build automation frameworks to verify both your own code and the squad’s deliverables.
Documentation: Treat documentation as code. Create and maintain detailed technical documentation—including APIs, dependencies, and integration guides—to ensure the software is accessible, maintainable, and seamlessly integrated by customers.
Review: Participate in Code Reviews not just for logic, but with a focus on Testability and Safety, ensuring the code is robust before it merges.
Quality Ownership
Champion a culture of total ownership. You define "Done" not merely by implementation, but by delivering software that is Production-Ready and rigorously validated.
Actively troubleshoot and resolve build/test failures in the CI/CD pipeline as if they were your own code errors.
AI-Augmented Workflow
Leverage AI tools such as GitHub Copilot and Claude to maximize productivity.
Use AI to lower the barrier for cross-functional tasks (e.g., generating test scenarios for complex logic, or debugging unfamiliar code), allowing you to focus on high-value engineering challenges.
Customer Support
On-site Support: Support major test events with partners on-site (domestic/international), troubleshooting integration issues directly in vehicle or test bench environments to ensure successful deployment.
Technical Communication: Serve as a primary technical contact for integration issues, translating complex engineering concepts into clear guidance for customer engineering teams.
