The Opportunity
Sonatus is at the forefront of the automotive industry’s transformation into a software-defined future, where vehicles are continuously evolving platforms rather than static products. This shift creates a unique opportunity to work on cutting-edge technologies that directly impact how OEMs design, deploy, and enhance their vehicles. At Sonatus, employees are empowered to innovate, collaborate with leading automakers, and solve complex, real-world challenges at scale. It’s an environment where forward-thinking engineers and leaders can shape the next generation of mobility while growing alongside a company driving meaningful change across the industry.
Sonatus is seeking a highly motivated Senior/Staff AI Engineer to join our Customer Engineering (CE) team and help deliver AI-driven solutions for automotive OEM and Tier-1 customers.
In this role, you will work directly with customers to understand real-world challenges in their vehicle environments and translate those challenges into practical solutions using Sonatus AI technologies.
A key responsibility of this role is to own the integration and deployment of AI capabilities on the Sonatus AI platform across cloud environments (Sonatus or customer-managed) and vehicle systems, ensuring reliable, scalable, and seamless interaction between vehicle-side data and cloud-based intelligence.
This role operates in a forward-deployed engineering model, partnering closely with customer teams to define problems, build solutions, and drive production deployment and adoption end-to-end.
Role and Responsibilities
- Own end-to-end delivery of AI-driven solutions, from problem definition and use case shaping to production deployment, adoption, and measurable customer impact
- Lead and own customer engagements and project execution, particularly for Korea-based programs, driving alignment, execution, and successful delivery across customer and internal teams
- Partner directly with OEM and Tier-1 customers to identify ambiguous problems, challenge assumptions, and drive high-leverage technical and business outcomes as a trusted advisor
- Design, build, and deploy AI/ML solutions across vehicle, edge, and cloud environments, including data pipelines, model development, system integration, and continuous iteration based on real-world data
- Lead system integration across vehicle and cloud ecosystems, ensuring reliable data flow, interoperability, and seamless interaction between in-vehicle systems and backend platforms
- Drive technical decision-making and alignment, clearly communicating trade-offs, constraints, and long-term architectural implications to both technical and executive stakeholders
- Own production deployment, scaling, and reuse, ensuring solutions are successfully adopted and expanded across vehicle programs, platforms, and regions
- Collaborate cross-functionally with Product, AI Platform, and Engineering teams to influence platform evolution and improve scalability, reliability, and usability based on field learnings
Requirements
- Bachelor’s degree in Computer Science, Engineering, or related field (Master’s or PhD preferred)
- 10+ years of experience in AI / Machine Learning, Data Engineering, or related domains
- Solid understanding of machine learning, data analytics, and AI-based systems, including practical experience delivering real-world solutions
- Experience designing and working with data pipelines, analytics workflows, and model-driven systems
- Experience integrating platform-based solutions with external systems, data pipelines, and APIs
- Strong hands-on experience developing, integrating, and deploying AI/ML-based solutions in production environments
- Proven ability to influence customer direction and drive technical decision-making in customer-facing engagements
- Experience leading technical discovery, shaping ambiguous problem spaces, and proposing scalable solution approaches
- Proven ability to communicate complex technical concepts clearly and persuasively to both technical and non-technical stakeholders
- Ability to operate effectively in ambiguous environments and drive clarity, alignment, and execution
- Experience in customer engineering, solution engineering, or forward-deployed engineering roles is highly preferred
- Familiarity with modern AI methodologies such as Agentic AI, Retrieval-Augmented Generation (RAG), or data-driven automation is a plus
- Experience in automotive software, vehicle systems, or mobility-related domains (nice to have)
