Our Miami office opens in Q1 2027; until then you'll work from our SF office or remotely with regular customer travel. Start: Immediately Reports to: SVP, Business Development ABOUT THE ROLE Luxor's sales team is organized into specialist pods, and one person owns each pod's revenue. We're hiring the person who will own Energy & Commander, our fastest-growing product surface and our biggest untapped opportunity. - Luxor Energy is a Bitcoin-native retail electric provider (REP) in ERCOT and a QSE expanding into SPP. We help large flexible loads cut power costs and earn from their flexibility through competitive retail supply, demand response (ERS), ancillary services, 4CP avoidance and CRR credit maximization. Miners can post collateral in BTC or settle power bills directly from pool earnings. - Luxor Commander is our fleet management platform, already running on roughly 500 MW of mining infrastructure. It gives operators real-time monitoring, remote control and automated curtailment that responds to hashprice and energy prices. Texas and SPP are full of miners and other large loads heading into supply renewals. Your job is to turn that footprint into revenue. This is a hunter-closer seat. Our energy, operations and product teams will support you, but you own the pipeline, the number and the close. WHAT YOU'LL DO - Own Energy & Commander revenue and the quarterly targets you agree with leadership. - Source and close new REP, QSE and demand-response business with Bitcoin miners, data centers and other large flexible loads in ERCOT and SPP. - Convert Commander's free and trial users to paid, and pair Commander with energy contracts so they sell as one deal. - Get ahead of the renewal calendar: know when every target site's power contract renews, and be in the room 6+ months out. - Build and work broker and channel relationships, while growing a direct RFP flow. - Run the full cycle: outbound, discovery, pricing (adders, DR revenue shares, term structures), proposals, negotiation and close. - Spend 80%+ of your time in front of customers and partners, including on-site visits and industry events. - Bring what you learn in the market back to product: what customers want, what competitors charge and where the openings are. - Help hand off to other key decision makers or cross-sell the rest of the Luxor stack (Pool, LuxOS, derivatives, hardware) when the account calls for it. WHAT WE'RE LOOKING FOR - 5+ years in B2B sales or business development, with a record of deals you personally sourced and closed. Bring numbers. - A working understanding of US power markets: retail supply, adders, index vs. fixed pricing, demand response and ancillary services. ERCOT and/or SPP experience is a strong plus. - Comfort selling technical, consultative products to senior operators, CFOs and energy managers. - A network among miners, data center operators, brokers or energy market participants is a plus. - Exposure to Bitcoin mining, ASICs or mining management software is a plus. - Willingness to work in office in Miami and travel regularly to customer sites and events. THIS ROLE IS FOR YOU IF - You'd rather own a number than a strategy deck. - You get energy from connecting with a net new site and turning it into a signed contract. - You learn markets fast and can explain energy economics in plain English. THIS ROLE IS NOT FOR YOU IF - You prefer to set strategy and hand deals to someone else to close. - You need someone else to schedule your follow-ups. WHAT WE OFFER - Competitive base plus uncapped, gross-profit-based commission. - Real ownership: you are accountable for two product lines. - A full ecosystem to sell (pool, firmware, derivatives, hardware, energy, software), so you can build deals no single-product competitor can match. - Health, dental and vision, 401(k) matching and unlimited PTO.

You’ll find and sign affiliates and partners with large networks in MENA and LatAm: crypto exchanges and media, iGaming operators and affiliate networks, brokers, fintech players, streamers and influencer agencies. Our offer to them is one of the strongest on the market: a high commission on every sale their audience makes, plus a lifetime revenue share. Your job is to put that offer in front of the right people and close the deal. This is not a desk job and not mass cold outreach.

Closing: run the full cycle Own every deal end to end: first contact, negotiation, agreeing terms, onboarding, launching traffic and the first sales. Negotiate with founders and senior management, and show clearly what partnering with GoMining is worth to them and their audience. When a partner says no, find out why and bring that back so we can sharpen the offer. Growing: turn partners into volume Grow the partners you’ve signed: higher volume, new formats, and special offers for their audiences. Keep your pipeline up to date in the CRM, report weekly on the funnel, and file a short results report after every trip. Share what you see in the MENA and LatAm markets (competitor offers, partner expectations, local payment specifics) with the team. What success looks like First month: you know the product and the partner offer inside out, your MENA/LatAm pipeline is mapped, and your conference and meeting calendar for the next quarter is set. First 3 months: you’re running a steady rhythm of in-person meetings, your first partnerships are signed and live, and the first sales are coming in through your partners. Ongoing: we measure you on new active partners per month, sales volume and revenue from those partners, and how well your meetings convert into signed deals.
