Research company & role

Her words: Familiarize yourself with our mission, projects completed, and the energy storage industry. Review the JD — key responsibilities and qualifications. The interview will focus on your experience and knowledge relevant to the role’s requirements.

Company in 45 seconds

Say this if she asks what you know about ON

"You started around 2015 as a storage developer and integrator in Latin America — Cooper and de Azevedo out of Miami, building battery-storage projects. Then you became a US independent power producer in Texas — owning and operating storage and selling into ERCOT. In February you launched AI UPS — not a BESS: inline at medium voltage, zero transfer time. In July, 5 GW with Crusoe. Commercially you're three businesses at once — manufacturer, integrator, asset owner — so contract terms don't just allocate risk, they decide whether a project gets financed."

Your role exists because of the last dot.
Identity to remember: unusually, they are developer + system integrator + asset owner in one company — historically retaining ~80% of the US projects they build. That triple identity changes what their contracts must do (Section 06).

The pitch in one breath: AI demand broke the grid's assumptions → regulators now require ride-through → ON.energy has the patented hardware → the Crusoe deal made the contracts enormous → they need someone to price the risk in them. That someone is the role.

Reporting line is unconfirmed — the highlighted path is inferred from the Finance filing and the CFO-review language in the JD. Asking Andrea "who does this report to?" is a natural, smart question.
Why this role opened (mission → seat)

ON’s pitch: AI power demand outran the grid; they sell a product that keeps campuses online and grid-safe. Ashburn (Jul 22) is the live proof near your house. Crusoe is why a Finance-owned commercial seat exists now — multi-year paper where margin lives or dies in the terms.

The JD, translated for a 30-minute screen

She said the interview focuses on experience relevant to the role. These are the JD lines she’ll hear as “fit.” You don’t recite the posting — you land proof against it.

JD asksWhat she’ll listen forYour proof in this call
Grey zone: term sheet → signed contractDo you own commercial terms, not admin paperwork?Background arc → “quality of the deal, not volume of transactions”
Payment, LDs, LoL, indemnity, warranties, security, change ordersCan you name clause types and what they cost?Empower / Sunshine archive — same clause surface as the posting
Spot risk early, price it, bring alternativesCommercial courage without waiting for LegalRisk lens: engineer / cap / transfer / price / walk
Counterweight to Sales; protect margin & risk appetiteWill Finance trust you?Role is under Finance; incentives = margin & risk, not bookings
Know when to push, compromise, walk awayJudgment under pressureDefault STAR: Empower (held the floor). Alt: Sunshine (signed)
Explain terms to executives without legal jargonClear, concise, business languageEvery script below is plain English on purpose
7+ yrs complex B2B; energy preferredScale gap vs kind of workOwn it: same clauses, fewer zeros; they said zeros are teachable
Build playbooks / frameworksCan you institutionalize judgment?Two-document playbook (locked addendum + discussion guide)
“What does this cost us?”Instinct on first read of a clauseEmpower $75K LDs deleted; liability capped to trailing commissions

One-line industry map (if she stays high-level)

Problem

AI campuses trip offline to protect themselves → gigawatts vanish → grid destabilizes (Ashburn).

Product

BESS sits beside the path and reacts. AI UPS is the path — inline, zero transfer.

Regulation

Ride-through mandates (NOGRR 282 in Texas; NERC/PJM moving). Compliance is a purchase order.

Your job

Price and paper the deals so growth doesn’t eat the company.

2

Discuss your experience (STAR)

Her words: Be ready to discuss past projects and achievements in detail using STAR (Situation, Task, Action, Result). For technical roles, be prepared on BESS, ISO standards, QMS, or other areas on your resume.

Which story answers which JD line

If she asks…DeployJD line it proves
Walk-away / held a hard line / push backEmpower №3 (default)Know when to walk; LDs, LoL, indemnity rebuild

What’s a BESS? / product fluencySpot-check script belowIndustry familiarity she flagged in the email
Why you without hyperscaler paper?Scale-gap scriptTheir own line: teach modeling, not commercial courage
Visual — BESS (parallel) vs AI UPS (inline) — open before her spot-check
Fig. 9 — THE distinction: parallel vs inlineIf you internalize one diagram, make it this one
CONVENTIONAL: BESS (PARALLEL) GRID raw grid power DATA CENTER BESS beside the path has to detect → respond → TRANSFER TRANSFER TIME ≈ 4 ms — an eternity voltage already sagged; GPUs already saw the hit ON.ENERGY: AI UPS (INLINE) GRID AI UPS — IS the path AC→DC BATTERY DC→AC DATA CENTER every watt, all the time — load never touches raw grid power TRANSFER TIME = 0 — nothing to transfer always in circuit · medium voltage 13–35 kV · at the site boundary Bonus of medium voltage: equipment moves outdoors (freeing space for compute) and ONE system shields the whole plant — IT load, chillers, pumps — not just the server racks.
The sixty-second version: a BESS sits beside the power path and reacts; even a fast static switch takes ~4 ms, and the GPUs have already seen the disturbance. AI UPS is the power path — AC in, buffered through the battery, clean AC out, continuously. Transfer isn't fast, it's zero. This is why the CTO wrote "Don't Call Me BESS."
Before you speak Empower

The Result line still has a [FILL] — one true sentence on how it ended. Don’t improvise a closing you can’t defend.

Background — 90 seconds (opens the call)
Shape

"I've spent nine years in US solar, mostly on the front end — Sunrun, Circle of Excellence in 2020, then Raynora in the Mid-Atlantic. What kept pulling me deeper was after the handshake: how it's financed, what the terms obligate you to, what happens when something underperforms. Corporate finance degree, own P&L. This role is that work at the scale where it matters, in the market on my doorstep."

Maps to JD: commercial operator, not contracts admin; energy sector preferred.

Empower — default STAR (walk-away / held the floor)
30-second version

"The deal I most wanted came with two $75K liquidated-damages clauses and uncapped liability. I rebuilt the entire risk allocation in a 16-section addendum — that was my written floor. [FILL — half sentence: what they did]. So I walked. Decide the walk-away line before you fall in love with the deal, and put it in writing so it can't drift."

Full STAR + before/after table: dossier §10B.

Team Sunshine — alt STAR (signed deal)
30-second version

"An installer's president answered my term sheet with a pre-signed contract on his paper. Over ten drafts I traded rather than demanded — gave up chargebacks to win payment timing and a liability cap, took $2.40 TPO to get $2.05 commercial — and dropped two of my own asks when he correctly called them overreach. We signed. That playbook became my template."

№2 — The Covenant Solar Lease℠ — structuring, with the numbers attached

Designed a Sharia-compliant lease product (Ijara Muntahia Bittamleek) satisfying the IRS true-lease test (Rev. Rul. 55-540 eight factors) and Islamic finance constraints simultaneously; locked terms include 20-year term, 8% nominal target IRR on the lease payment stream, ~11–12% all-in SPV yield including ITC and MACRS bonus depreciation, Year-6 purchase-option gate deliberately set one year past the §48E five-year recapture window, FMV methodology at 13% of cost declining 1%/yr to a 5% floor, net buyout = gross FMV minus offsetting obligations floored at zero; benchmarked the design against four national contracts (Sunrun PPA, Participate Energy, Skylight, EnFin) clause by clause, including hell-or-high-water payment provisions; separately produced a §48E Beginning-of-Construction reference covering the 5% Safe Harbor vs the four-year continuity safe harbor and §6418 transferability at 88–94 cents on the dollar.

Caution: keep counterparty-confidential specifics out of it (you've restricted Covenant details in other applications for competitive reasons — same discipline applies here; the structure and the model are yours to discuss, the deal specifics may not be).

When your JD says modeling is teachable — I taught myself the version that matters: what a term does to the economics.

Scale gap — “You haven’t done hyperscaler EPC/supply”
Shape

"Fair — I haven't negotiated a nine-figure supply agreement with a hyperscaler's counsel, and I won't pretend otherwise. In the last ninety days I've negotiated ten entity-to-entity commercial agreements — clause surface was your job description: milestone payments, LDs I got removed, liability caps I added, asymmetric indemnity I reversed, change-notice ladders, payment security, arbitration. Two signed, two walked on named dealbreakers, one pulled when diligence failed. The gap is the zeros — your posting says zeros are teachable. Judgment about when to push, trade, and walk is in my archive. Can you flex that bar? If not, is there a level below with the same trajectory?"

BESS / ISO / QMS — her technical spot-check
BESS

"A battery energy storage system — batteries, power conversion, controls — sits beside the power path and stores/dispatches over minutes and hours. ON has built those for years. Your CTO's point: BESS is parallel — it detects and transfers; even a fast switch is milliseconds, so GPUs already saw the hit. AI UPS is inline; nothing to transfer."

ISO (manufacturing context): ISO 9001 quality-management standards. (In grid talk, “ISO” can also mean a grid operator — let context tell you.) QMS: documented processes that make quality repeatable and auditable — relevant because ON builds hardware.

Risk lens — if she goes commercial
Three verbs

"Engineer it out if we can. Cap it if we can't. Transfer it if someone else holds it cheaper. Price what's left. Walk if it can't be priced."

Maps to JD: identify risk, quantify, alternatives; “what does this cost us?”

Why ON / Ashburn
Shape

"Two weeks ago three gigawatts dropped off PJM after a fault in Ashburn — twenty minutes from my house. Then I read ON's inline architecture — first product I'd seen that addresses both directions of that problem. Regulatory deadline and customer self-interest point at the same purchase order. I want the commercial side of that."

Comp · why leaving
Comp

"Targeting $140–160K base with bonus — but I'd rather calibrate to your band. What range is the role approved at?"

Why leaving

"Nothing's wrong where I am. Nine years paid per transaction; the interesting work moved upstream into structure and terms. I want a seat where the output is deal quality, and where I'm building playbooks — not starting from zero every month."

Questions for her

Her words: The interview is a two-way street. Prepare thoughtful questions about the team, culture, daily responsibilities, or future challenges.

Pick three. Phrase them so they also show you read the JD (reporting line, what triggered the seat, how commercial vs sales works).

Harder commercial questions (change orders, lenders, warranty back-to-back, day-90) → save for hiring manager · dossier §12.
