Principal EV Charging Systems Engineer EVSE and OCPP

Principal EV Charging Systems Engineer - EVSE & OCPP

Company: DynaChrg Inc.

Location: Calabasas, California - On-site

Employment Type: Full-Time

About DynaChrg

DynaChrg develops intelligent EV charging and energy-management technology. Our EVES™ platform enables multi-vendor charger management, real-time monitoring, charging transactions, energy optimization, dynamic charging control, and grid-aware services.

Position Summary

DynaChrg is seeking a senior-level EV charging engineer with deep, hands-on experience integrating commercial EV charging equipment with Charging Station Management Systems (CSMS) using OCPP.

This role owns the charger-facing technical integration layer of EVES™, including EVSE evaluation, onboarding, interoperability testing, qualification, validation, troubleshooting, and production support.

This is a systems integration and interoperability role-not an EV charging construction, installation, or electrical-infrastructure design role.

Mandatory Experience

• 5+ years of relevant professional engineering, systems integration, EV charging product, or technical product experience.
• Minimum 3 years of direct, hands-on EVSE-to-CSMS integration experience in commercial EV charging.
• Deep hands-on professional experience with OCPP 1.6J , including analyzing and troubleshooting charger-to-CSMS message flows.
• Experience with commercial AC Level 2 and/or DC fast chargers .
• Experience reviewing OCPP messages, charger logs, backend logs, telemetry, protocol traces, and/or network traffic .
• Ability to diagnose issues across charger hardware, firmware, configuration, networking, OCPP, and CSMS/backend behavior .
• Experience with EVSE interoperability testing, qualification, validation, or production support.
• Experience working directly with EVSE OEM engineering/technical teams .
• Ability to work full-time on-site in Calabasas, CA , or relocate to the Greater Los Angeles area.

Experience primarily in charger installation, site deployment, construction, electrical design, utility coordination, power systems, or general commissioning does NOT substitute for direct EVSE-to-CSMS/OCPP integration experience.

Key Responsibilities

• Lead integration of commercial EVSE with DynaChrg's EVES™ platform.
• Configure, validate, and troubleshoot OCPP 1.6J communications; support OCPP 2.0.1 integrations.
• Analyze OCPP message flows, charger/backend logs, telemetry, and network captures.
• Diagnose root causes across hardware, firmware, configuration, networking, security, OCPP, and backend layers.
• Lead onboarding and technical qualification of new charger manufacturers, models, and firmware.
• Perform hands-on EVSE interoperability, regression, and validation testing.
• Define approved charger firmware, configurations, network settings, and integration requirements.
• Work directly with charger OEMs to resolve firmware and interoperability issues.
• Troubleshoot TCP/IP, DNS, DHCP, routing, firewalls, Ethernet, Wi-Fi, cellular/LTE/5G, SIM/eSIM, TLS, and certificate-related connectivity.
• Serve as a senior escalation point for complex production EVSE integration issues.
• Support charger commissioning and field troubleshooting when needed.

Required Qualifications

• Bachelor's degree in Computer Engineering, Electrical/Electronics Engineering, Computer Science, Telecommunications, Embedded Systems, or related field; equivalent technical education may be considered with substantial commercial EVSE experience.
• Strong understanding of EVSE architecture, charger firmware, charging workflows, networking, and charger-to-backend communications.
• Strong root-cause analysis, technical documentation, communication, and problem-solving skills.

Strongly Preferred

Experience with multiple EVSE manufacturers, both AC Level 2 and DC fast charging, OCPP 2.0.1, Wireshark, charger firmware qualification, automated protocol testing, hardware-in-the-loop testing, TLS/mTLS, smart charging, ISO 15118, Plug & Charge, PKI, OCPI, or V2G.

Interview Expectations

Candidates must be prepared to discuss specific work they personally performed , including EVSE manufacturers/models, CSMS platforms, OCPP versions used in production, a charger-to-CSMS integration they owned, OCPP messages analyzed, and a real interoperability or firmware/networking issue they diagnosed and resolved.
