About The Role

This position sits within the core Engineering R&D group focused on our Solid-State Transformer (SST) platform. Our team is responsible for defining and delivering the embedded Linux platform architecture that underpins Enphases next generation of grid-scale energy conversion systems products that push the boundaries of power density reliability and intelligent control at the edge. Were looking for a technically deep systems thinker who can set architectural direction drive it through to silicon and grow a team around it.

What You Will Do

• Define and own an AI-forward embedded Linux platform architecture for SST power systems including BSP strategy boot architecture and OS configuration.
• Establish system software frameworks for real-time control integration inter-process communication and fault management across complex multi-board and multi-domain architectures.
• Leverage AI-assisted development tools (e.g. LLM-based code generation static analysis augmentation and intelligent search across codebases) to accelerate architecture documentation code review and root-cause analysis and establish team norms for where AI assistance is appropriate where it requires validation and where human judgment remains the standard.
• Partner closely with hardware power electronics and control engineers to co-define hardware/software boundaries peripheral interfaces and system bring-up strategies.
• Drive platform reuse and scalability across product generations establishing reference architectures board support layers and software build systems that downstream teams can build on.
• Lead architectural reviews set coding and integration standards and own key technology decisions from concept through product launch.
• Manage and mentor a small team of embedded software engineers; contribute to hiring technical growth and team structure as the organization scales.
• Collaborate with cross-functional teams including systems validation product engineering and manufacturing to support DVT factory test and field quality loops.

Who You Are And What You Bring

• B.E./ or M.S./ in Electrical Engineering Computer Engineering or Computer Science
• B.E. with 15 years or M.S. with 12 years of embedded systems experience in a product development environment (non-academic)
• Deep hands-on experience with embedded Linux build systems BSP development device tree and kernel configuration
• Strong systems architecture instincts: comfortable participating in SoC selection memory map boot sequence and OS partitioning decisions
• Experience with high-reliability or safety-relevant embedded systems; familiarity with IEC or UL standards for industrial or power electronics products is a plus
• Solid understanding of hardware/software co-design comfortable reading schematics working with hardware bring-up and owning driver development for custom peripherals
• Experience integrating real-time control loops with a Linux application processor
• Track record of shipping products from architecture definition through manufacturing release and field support
• Proficiency in AI-forward code development in applicable languages (C C Python).
• Experience with software configuration management CI/CD pipelines and Atlassian tooling (Jira Confluence)
• Demonstrated ability to lead engineers technically setting direction conducting reviews and building team capability with or without formal reporting relationships
• Experience with power conversion systems energy storage or grid-connected equipment is a strong plus
• Familiarity with secure boot OTA update mechanisms and embedded cybersecurity considerations is a plus
• Experience with CAN Modbus EtherCAT or other industrial communication protocols is a plus

The salary range for this position is $180000 to $226800 and may vary based on experience skills and location. Thispositionis also eligible for bonus equity and benefits with final compensation determinedin accordance withapplicable laws and internal equity.
