About IONNA 

Welcome to IONNA, the joint venture founded by eight global automotive leaders: BMW, General Motors, Honda, Hyundai, Kia, Mercedes-Benz, Stellantis and Toyota. At IONNA, we're revolutionizing the EV charging landscape in North America by creating a high-powered charging network that's set to redefine the way we drive. 

Our Mission: Make EV charging reliable, accessible, and convenient. With a commitment to deploying a minimum of 30,000 chargers across North America, we're shaping the future of electric mobility, exceeding industry standards and leading the charge toward a sustainable, zero-emission tomorrow. 

Position Summary 

The Principal Charging Software Engineer owns charger software end-to-end: firmware quality, the charging-software roadmap, cross-cutting software architecture, and the full software development lifecycle (SDLC) with our charger vendor. As the charger portfolio grows and on-board software becomes increasingly complex, this role ensures software stops being the constraint on reliability, directly defending the uptime and first-plug-success metrics that drivers, OEMs, and third-party raters judge us on. 

The successful candidate brings a strong software-engineering background, deep familiarity with EV charging technology, and a proven track record leading software architecture and managing a vendor's software delivery lifecycle at the scale of a public charging network. 

Key Responsibilities 

Charging Software Architecture & Roadmap 

• Own the architecture and technical direction for charger software and firmware across the EVSE portfolio, including functional safety, software FMEA, APIs, and state-machine design. 

• Define and maintain the charging-software roadmap and align it with the vendor's roadmap; lead gap analysis to sequence features, quality improvements, and platform changes against IONNA's KPI targets. 

• Ensure the charger software is fully interoperable across the broader IONNA ecosystem, embedding the V2G communications and OCPP stack to integrate seamlessly with IONNA's CPMS, payment systems, and Plug & Charge, keeping the stack scalable, maintainable, and reliable as the portfolio expands. 

Charging System Vendor SDLC Leadership 

• Lead the full charger software development lifecycle: requirements, design reviews, release planning, acceptance criteria, quality gates, and release notes and documentation. 

• Drive predictable, on-time software deliveries from the vendor; hold release governance and improve delivery cadence and quality. 

• Serve as the primary technical owner of the charger software relationship, partnering with the Charging Hardware Lead on combined HW/SW releases. 

• Maintain and manage a comprehensive set of charging-software requirements and acceptance criteria. 

Quality, Reliability & Release Governance 

• Own charger software/firmware quality outcomes, driving regressions and escaped defects toward zero and protecting uptime and 1st attempt success. 

• Partner with the Testing & Technology Evaluation team to gate releases, validate firmware, and ensure testability is designed in from the start. 

• Lead root-cause analysis on software-driven field issues and support Tier-3 obligations to resolution. 

• Make major contributions to go/no-go release decisions and shape pilot strategy; manage, measure, and continuously improve software-related KPIs for the charging systems. 

Cross-Functional Collaboration 

• Work closely with Hardware, Testing, Product, Program Management, and Operations to align charger software with the broader roadmap and deployment plans. 

• Translate technical software findings into clear, actionable insights for engineering, product, and executive stakeholders. 

• Stay current with the EV charging landscape and evolving standards, driving vehicle interoperability and proactively adapting the software roadmap and architecture. 

Required Qualifications 

• A minimum of 8 years in software or embedded-systems engineering, including technical or team leadership. 

• Proven experience owning the software development lifecycle (SDLC) with a hardware or firmware vendor: requirements, releases, and quality gates. 

• Demonstrated ability to lead software/firmware architecture for connected hardware (chargers, embedded devices, or comparable systems). 

• Strong command of Agile/Scrum, modern release management, and CI/CD practices. 

• Bachelor's degree in Computer Science, Computer/Electrical Engineering, or a related field (or equivalent practical experience). 

• Exceptional communication and program-management skills to progress discussions with vendors and senior stakeholders. 

Preferred Qualifications 

• Direct experience in public DC fast charging at a charging network operator. 

• Hands-on experience managing an EVSE/charger vendor's software relationship. 

• Familiarity with firmware quality, OTA update systems, and charger field reliability. 

• Familiarity with V2G coms, Plug-and-Charge, PKI, OCPP and relevant standards (e.g. ISO 15118). 

• Experience partnering with automotive OEMs on vehicle-to-charger interoperability.
