Lead - Techno-Commercial (BESS)

Job Purpose:The Techno-Commercial Lead owns the bridge between technical choices and commercial outcomes ensuring cell technology, system architecture, and supplier terms translate into competitive cost/kWh, protected margins, and execution ready manufacturing.This role is the BUs techno-commercial interface for external sourcing:Select the right cell/critical components for India conditions and project duty cyclesConvert technical realities (degradation, throughput, thermal limits, safety) into defensible contracts (warranty, guarantees, back to back terms, claim evidence)Enable repeatable scale by enforcing a standard product catalog and supplier qualification gates (avoid bespoke, one-off commitments)Key Responsibilities1) Cell Technology Strategy & Technical BenchmarkingEvaluate LFP and alternates (as applicable) on performance, degradation, safety margins, thermal behavior, and lifecycle cost for Indian site conditions and duty cycles.Benchmark global suppliers on cost stability, safety margins, throughput capability, and Indian operating suitability; Track global cost curves and technology shifts (cell format, chemistry, safety features)Define a cell selection strategy tied to cost-per-kWh and lifecycle margin (incl. implications for augmentation, warranties, and availability commitments)2) Supplier Technical Engagement & Commercial NegotiationLead the technical-commercial front end of supplier engagement: build structured RFQs with technical scope, compliance matrices, test evidence, and commercial guardrailsCreate supplier comparison dashboards across: price stability, lead time, capability, quality systems, traceability, warranty strength, and support modelPartner with Wind Procurement to close defensible LTAs with:- pricing protections / indexation logic- FX risk structure- delivery safeguards (lead times, penalties, buffer strategy)- audit rights / change notification requirements- warranty claims support commitmentsValidate supplier claims before scale through sample builds / data review / factory audit inputs (with CTO + Manufacturing)3) System Architecture & Cost IntegrationTranslate cell-level decisions into system configuration logic (module/rack/container sizing, electrical topology, thermal strategy) optimizing manufacturability, yield, safety, and cost-per-kWhAlign integration philosophy for BMS/PCS/EMS with commercial commitments (no hidden integration risks that become LD/warranty triggers)Drive standardization + modularization of container platforms to support repeat bids and faster engineering cycles, consistent with BUs standard catalog principle4) Warranty Structuring & Lifecycle Risk TranslationDecode and negotiate supplier warranty structures: throughput warranties, degradation caps, cycle/calendar assumptions, operating window limits, claim evidence requirementsQuantify degradation and augmentation assumptions into commercial exposure; ensure whats guaranteed is technically defensibleEnsure back-to-back alignment between supplier warranties and customer commitments (hardware supply, EPC performance guarantees, O&M SLAs), partnering with Commercial/Finance for provisioning and with OMS for workflow designDefine standard warranty clause library and claim playbook (evidence, data logs, traceability, test records, RCA governance)5) Customer technical support & bankabilitySupport Wind BD/Sales and bid desk with technical-commercial inputs for tenders (compliance responses, performance assumptions, clarifications)Participate in customer technical discussions and lender/bankability reviews: articulate safety baseline, reliability logic, warranty coverage, and supplier support model6) Market Competitiveness & StrategyTrack global storage cost curves, chemistry innovation, and competitive positioningSupport commercial team in customer technical discussions and bankability reviewsDevelop technology roadmap aligned to 1.5 GWh manufacturing rampExperience & Background6 to12+ years in lithium-ion batteries, BESS, EV battery systems, or adjacent power-electronics/storage domainsProven experience in supplier technical evaluation + techno-commercial negotiations (cells and/or critical subsystems)Comfort with cross-border sourcing (including China/Asia supplier ecosystems), logistics/FX considerations, and quality evidence expectationsExperience supporting EPC/grid-scale storage deployments or utility tender requirements is strongly preferredDomain ExpertiseStrong command of LFP degradation behavior, thermal safety fundamentals, and lifecycle economicsDeep understanding of pack architecture and containerized BESS system integration (BMS/PCS/EMS interfaces)Working knowledge of warranty structures (throughput, degradation, operating window constraints, availability/claim mechanics)Practical understanding of manufacturing yield, traceability requirements, and quality governance (PFMEA/control plans level familiarity)Supply-chain risk awareness: FX exposure, lead-time volatility, geopolitical concentration risk, and mitigation leversCommercial AcumenAble to negotiate price, warranty, and risk-sharing structures - grounded in technical realitiesStrong analytical ability in cost modelling and lifecycle economics; structured documentation mindset (RFQ discipline, nomination packs)Comfortable leading supplier/customer discussionsEducationB.E./B.Tech in Electrical, Mechanical, Chemical, Energy EngineeringPostgraduate specialization in Energy Systems / Power Electronics preferredMBA (Strategy / Technology) is a plus
