Vehicle-to-Grid Systems Engineer Job Description

Vehicle-to-Grid Systems Engineers solve a deceptively complex problem: an electric vehicle is designed to move people from place to place, but when it's parked — which is roughly 95% of its life — it's a mobile battery pack that could be doing useful grid work. The systems engineer's job is to make that happen reliably, safely, and economically.

The role operates at the boundary between three technical domains that rarely talk to each other: automotive power electronics and battery management, grid operations and utility interconnection rules, and software systems that coordinate fleets and respond to market signals in real time. Most engineers arrive strong in one of these domains and spend the first few years of a V2G career building fluency in the other two.

On a given week, a V2G Systems Engineer might spend two days validating ISO 15118-20 protocol implementation on a new bidirectional charger with a hardware test bench, one day reviewing an interconnection study submitted to a utility for a fleet depot project, and a day analyzing telemetry from a 50-vehicle pilot to explain why round-trip efficiency came in 4 percentage points below the model. The Friday afternoon might be spent on a call with an OEM's battery management team, asking why the BMS is throttling discharge current below the contracted grid services threshold when the vehicle is above 40% state of charge.

Field commissioning is a regular part of the job at most organizations in the current market, because V2G hardware is new enough that factory testing doesn't catch everything. Fleet depot installations involve coordinating with electricians, EV fleet managers, utility field crews, and building automation vendors — each of whom has a different vocabulary for the same physical system.

The policy dimension is unusually prominent in V2G compared to other power systems roles. Utility tariff structures, wholesale market eligibility rules, and state clean energy mandates directly determine whether a V2G business model works. Engineers who understand the regulatory and market context — not just the technical implementation — are significantly more effective at scoping projects that can actually pencil out economically.

The work is genuinely novel. V2G at commercial scale barely existed in the United States five years ago. Engineers in this field are writing the standards, building the first reference implementations, and discovering what the failure modes are. That creates a high tolerance for ambiguity and a demand for engineers who can function effectively without established playbooks.

Education:

• Bachelor's degree in electrical engineering, power systems, or electrical and computer engineering — the baseline for most roles
• Master's degree in power systems, energy systems, or controls engineering is common and often expected at national labs, utilities, and grid software companies
• Automotive or aerospace engineering backgrounds with strong controls and power electronics content are competitive

Experience benchmarks:

• Entry-level: 0–3 years; typically a software or hardware engineer from EV charging, energy storage, or automotive electrification moving into the V2G specialty
• Mid-level: 4–7 years; expected to own a subsystem — protocol stack, dispatch algorithm, or interconnection coordination — end-to-end
• Senior: 8+ years; leads cross-functional projects, interfaces directly with utilities and OEMs, mentors junior engineers, and contributes to standard-setting bodies

Technical skills:

• V2G and smart charging protocols: ISO 15118-20, CHAdeMO V2G, SAE J3072, OpenADR 2.0, IEEE 2030.5
• Power systems modeling: OpenDSS, PSCAD, CYME, PowerWorld — distribution feeder-level analysis
• Inverter and charger fundamentals: bidirectional AC/DC and DC/DC topologies, power factor correction, anti-islanding
• Battery management: state-of-charge and state-of-health estimation, cycle degradation modeling, thermal constraints
• Grid services: frequency regulation, demand response, distribution-level demand charge management, capacity market participation
• Programming: Python (pandas, NumPy for telemetry analysis), MATLAB/Simulink for controls modeling, some SQL for fleet data queries
• Interconnection standards: IEEE 1547-2018 (the primary DER interconnection standard in the U.S.), utility protective relay coordination basics

Certifications and professional development:

• PE license (Power Systems track) — required for engineering-of-record roles at utilities and consulting firms
• CharIN membership and ISO 15118 working group participation — signals protocol depth to employers
• NABCEP PV Installation Professional — useful background for engineers working on V2G-solar-storage hybrid projects
• UL 9741 Bidirectional Electric Vehicle Supply Equipment familiarity — newer standard that is becoming a hiring signal

Soft skills that differentiate candidates:

• Ability to translate between automotive engineers, utility engineers, and fleet operators who share no common vocabulary
• Comfort navigating regulatory filings and tariff documents without legal support
• Rigorous telemetry-based debugging — field problems in V2G systems rarely reproduce cleanly in lab conditions

V2G is transitioning from a research curiosity to a commercial reality on a timeline measured in years, not decades. The conditions that make that transition possible are converging simultaneously: EV penetration is crossing the threshold where aggregated fleet capacity is meaningful to grid operators; utility-scale energy storage economics have made grid flexibility a bankable commodity; and federal and state policy in the U.S. is explicitly targeting V2G as a grid resource.

The Inflation Reduction Act's investment tax credits for bidirectional charging infrastructure, combined with FERC Order 2222 opening wholesale markets to distributed energy resource aggregators, have created a policy framework that didn't exist three years ago. V2G fleet aggregators can now participate in frequency regulation markets in PJM, CAISO, and ERCOT — provided they can demonstrate the technical performance requirements, which is exactly what systems engineers are hired to prove.

Automaker commitment has shifted the calculus further. Ford's F-150 Lightning and Chevy Silverado EV both ship with V2G capability. Volkswagen's bidirectional charging rollout in Europe is creating technical precedent and trained engineer supply. Several OEMs have announced that V2G will be a standard feature on platforms launching in 2026 and 2027, which will rapidly expand the installed base from tens of thousands of vehicles to millions.

For engineers, the career outlook is strong and the supply-demand balance is favorable. The intersection of power systems engineering and EV technology is narrow enough that genuinely qualified candidates are scarce. Job postings at utilities, EV charging companies, grid software firms, and fleet operators have increased substantially since 2023, and compensation has tracked that demand.

The career ladder is still being defined, because the role itself is new. Common trajectories include advancing to principal or staff engineer within a V2G product organization, moving into grid integration leadership at a utility or ISO, transitioning into technical product management for bidirectional charging platforms, or moving into regulatory and policy roles where engineering depth is a differentiator. Several early V2G engineers have moved into founding roles at startups building the aggregation software layer.

The primary risk to the career outlook is technology adoption pace. V2G's economics depend on battery degradation being manageable, which requires continued improvement in BMS software and charger power quality. If early deployments show unacceptable degradation, adoption could slow. Current evidence from fleet pilots in the U.S. and Europe suggests that well-managed V2G use cases — primarily frequency regulation with shallow state-of-charge cycling — cause negligible incremental degradation. That evidence base is strengthening each year new pilot data comes in.

For engineers considering the field, the window to establish early expertise is open but not indefinitely so. The skills gap is real today; in five years, university programs will have produced a generation of graduates with explicit V2G coursework, and the competitive advantage of early specialization will compress.

Dear Hiring Manager,

I'm applying for the Vehicle-to-Grid Systems Engineer position at [Company]. My background is in distribution power systems engineering, and for the past three years I've been working on grid-side integration of distributed energy resources at [Company], including a 12-month assignment on a V2G pilot program with a regional transit agency operating 40 battery-electric buses.

On that project, I led the interconnection coordination with the local utility — preparing the IEEE 1547-2018 compliance documentation, coordinating protection relay settings with the utility's distribution engineering team, and working through the anti-islanding testing protocol that the utility required before they would authorize bidirectional export. We cleared interconnection approval in nine months, which was faster than most V2G commercial projects I've seen documented, largely because I pushed to get the utility's distribution planning engineer involved in the design review process before we submitted the formal application.

The technical challenge I spent the most time on was round-trip efficiency. The dispatch model projected 87% round-trip efficiency at the meter; our first month of telemetry showed 81%. I built a loss decomposition analysis in Python against the 15-minute interval data — charger idle losses, power factor penalties from the utility's metering, and a firmware issue on the onboard charger that was limiting ramp rates during export. Identifying the firmware issue took three weeks of back-and-forth with the OEM's application engineering team, but the fix recovered 3.5 percentage points of efficiency.

I'm looking for a role where V2G is the primary focus rather than a single project among broader distribution engineering work. [Company]'s fleet aggregation platform and the depth of your ISO 15118-20 protocol work are exactly the technical environment I want to be working in.

I'd welcome the chance to talk through the role in more detail.

[Your Name]
