Sales Specialist – Energy Storage Systems Buyers / Offtake

Circunomics • Full-time • Remote (Mainz) • 5d ago

Your mission

We’re hiring a Sales Specialist to identify, qualify, and win buyers for energy storage systems (ESS) across key customer groups, including energy storage operators, utilities, independent power producers (IPPs), energy project developers, and large C&I energy users. You will own the commercial pipeline from first outreach through negotiation and contracting—working closely with our ESS Partners, finance, and legal to turn market demand into executed deals.

1) Pipeline Generation & Market Development

Build and execute a prospecting strategy to reach ESS buyers across target segments and geographies.
Map accounts and decision-makers (origination, development, procurement, engineering, finance).
Develop a structured pipeline with clear qualification (use case, site, interconnection, timeline, budget, contracting path).

2) Deal Origination & Sales Execution

Lead sales cycles end-to-end: discovery, solution positioning, bid submission with our ESS partners, negotiation, and close.
Translate customer needs (capacity, duration, degradation, warranties, performance guarantees, delivery schedule) into winning commercial offers.
Coordinate internal stakeholders and our ESS partners to produce compelling proposals (technical + commercial + delivery plan).

3) Partnerships & Channels

Identify and manage strategic partners (EPCs, developers, integrators, advisors) to accelerate access to projects.
Create repeatable partner motions (lead sharing, co-selling, framework agreements).

4) Commercial Strategy & Pricing Support

Provide market feedback to inform pricing, product roadmap, and packaging (e.g., warranty structures, O&M options, availability guarantees).
Track competitor activity and customer buying criteria; recommend differentiators and positioning.

5) Contracting & Close (with Legal/Finance Support)

Support negotiation of key commercial terms (payment milestones, delivery, LDs, acceptance tests, warranties, service levels).

Your profile

3–8+ years in business development / B2B sales within energy storage, renewables, power markets, or grid infrastructure.
Proven track record of selling complex solutions with multi-stakeholder buying committees.
Comfortable with technical-commercial discussions (ESS sizing, duration, performance, degradation, warranties, grid connection constraints).
Strong negotiation skills and experience working with term sheets/contracts (with support).
Excellent CRM discipline (pipeline hygiene, forecasting, stage definitions).

Preferred / Nice-to-Have

Experience selling grid-scale BESS, hybrid projects (PV+storage), or storage services (tolling, capacity, ancillary services).
Knowledge of project development lifecycle (site control → interconnection → permitting → financing → EPC).
Familiarity with offtake structures and revenue stacks (capacity, arbitrage, ancillary services).
Existing network across utilities, developers, IPPs, and storage operators.
