Job description

Description

Enphase Energy is a global energy technology company and a leading provider of solar, battery, and electric vehicle charging products. Founded in 2006, our innovative microinverter technology revolutionized solar power, making it a safer, more reliable, and scalable energy source. Today, the Enphase Energy System enables users to make, use, save, and sell their own power. Enphase is also one of the most successful and innovative clean energy companies in the world, with more than 80 million products shipped across 160 countries.

Join our dynamic teams designing and developing next-gen energy technologies and help drive a sustainable future!

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 Enphase's next generation of grid-scale energy conversion systems — products that push the boundaries of power density, reliability, and intelligent control at the edge. We're 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./B.Tech or M.S./M.Tech 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 $130,000 to $226,800 and may vary based on experience, skills, and location. This position is also eligible for bonus, equity, and benefits, with final compensation determined in accordance with applicable laws and internal equity.
