Technical Program Manager - EV Charging Platform OCPP & NET Core

We are an end-to-end Renewable Energy provider. We offer products to commercial and enterprise clients in EV Charging solutions, Fleet Electrification, Solar Micro-grids, Energy storage, Hydroponic farming and Rain Water/Grey Water collection systems. We have been experiencing tremendous growth in all these areas and operate under several government rebate programs that ensure a steady and reliable flow of revenues. Our company handles the entire flow of providing these products and services beginning with Sales, Provisioning, Design and Engineering, Contracting and Construction, Servicing and Maintenance.

If you are passionate about the EV industry and working with awesome teams in a fast-growing company, we want to speak with you! Join us in making a meaningful impact!

You will own the delivery of our cloud Charging Station Management System (CSMS): a .NET Core platform that keeps thousands of DC fast chargers and Level 2 stations online, billing correctly, and compliant with OCPP 1.6J and 2.0.1. The chargers are hardware from multiple manufacturers running firmware we do not control; the platform must talk to all of them reliably, at scale, over long-lived Web Socket connections.

This is a hands-on technical program role, not a project-coordination role. You will read OCPP message logs, sit in on architecture reviews, decide when a firmware vendor's deviation from spec gets a workaround versus a pushback, and translate utility, regulator and customer requirements into engineering milestones the team can commit to. You are the single point of accountability for whether the platform roadmap ships on time and interoperates in the field.

You will work across backend engineering, firmware and hardware partners, QA and certification, field operations, and commercial teams, and act as the primary technical interface to charger manufacturers, charge point operators (CPOs), e-mobility service providers (eMSPs) and enterprise fleet customers.

• Own the CSMS technical roadmap: define program scope, phase gates, success criteria and release cadence, and keep it aligned with commercial commitments and regulatory deadlines.
• Translate business, customer and regulatory requirements into epics, acceptance criteria and milestones engineering can estimate and commit to.
• Run quarterly planning, weekly program reviews and release go/no-go decisions; publish status, risks and decisions to leadership in a form non-engineers can act on.
• Prioritize across competing demands (new charger onboarding, customer integrations, protocol upgrades, platform reliability) with explicit trade-offs, not a growing backlog.

• Oversee implementation and conformance of OCPP 1.6J and 2.0.1 across all supported profiles:
  Core, Firmware Management, Local Auth List, Reservation, Smart Charging, Remote Trigger, and 2.0.1 functional blocks including Provisioning, Authorization, Transactions, Tariff & Cost, Diagnostics and Security.
• Own the charger onboarding program: define the certification matrix per manufacturer/firmware version, run interoperability test plans, and sign off before a model is approved for field deployment.
• Maintain the known-deviations register: where a vendor's firmware departs from spec, decide between a platform-side workaround, a vendor fix, or declining support, and document the decision.
• Lead the OCPP 1.6J to 2.0.1 migration plan for the installed base, including dual-protocol operation, security profile upgrades (TLS, client certificates), and firmware rollout sequencing.
• Coordinate participation in OCA plugfests and third-party conformance testing; track OCPP 2.1 and ISO 15118-20 readiness.

• Partner with .NET Core architects on an event-driven microservices design that handles tens of thousands of concurrent Web Socket sessions, high-frequency Meter Values ingestion, and exactly-once transaction handling.
• Set and enforce non-functional requirements: connection stability, message latency, offline transaction recovery, horizontal scalability, observability and multi-region failover.
• Review technical designs for protocol correctness, backward compatibility and operational risk before implementation starts.
• Ensure the platform exposes clean, versioned APIs for customer portals, mobile apps, fleet management systems, payment processors and OCPI partners.
