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 — Please Apply Only If You Meet All Requirements

• 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.
