and system design\nLead feasibility studies for BESS and microgrid opportunities: load profiling, tariff and demand-charge analysis, diesel displacement, and techno-economic modelling (LCOE / LCOS, IRR, payback).\nSize BESS (power and energy), PV and genset capacity for hybrid and off-grid systems, including degradation, augmentation strategy and end-of-life planning.\nDefine system architecture: AC- vs DC-coupled, PCS selection, grid-following vs grid-forming operation, black-start and islanding capability.\nSpecify EMS / microgrid controller functions: peak shaving, load shifting, PV smoothing and ramp-rate control, spinning-reserve replacement, frequency and voltage support, and genset dispatch optimization.\nGrid integration and compliance\nLead grid-connection and interconnection studies (load flow, short circuit, protection coordination, dynamic/stability studies) and ensure compliance with PLN grid code and SPLN requirements.\nEnsure designs comply with applicable standards for battery safety and fire protection (e.g. IEC 62933, IEC 62619, UL 9540 / 9540A, NFPA 855) and Indonesian K3 / electrical safety regulations.\nProcurement and vendor management\nPrepare technical specifications and RFQs for battery systems, PCS, EMS/controllers, transformers and switchgear.\nRun technical bid evaluations and vendor due diligence (cell supplier, factory audits, warranty and performance guarantee terms, LTSA/O&M scope).\nNegotiate and review technical schedules of supply and EPC contracts, including availability, round-trip efficiency and capacity-retention guarantees.\nOperations and performance\nDefine performance KPIs (availability, Performance Ratio, Energy Absorption, RTE, SoH, diesel saved, curtailment, BESS Utilization) and monitoring/SCADA requirements.\nAnalyse operational data to optimise dispatch strategy, track degradation against warranty curves, and support warranty claims.\nBusiness development and team support\nSupport BD and proposal teams with technical solutions, budgetary pricing and client presentations for C&I, mining, industrial and island-grid clients.\nBuild internal BESS capability: templates, design standards, lessons learned, and mentoring of junior engineers.\nExpected deliverables\nFeasibility and sizing reports with techno-economic models for each opportunity.\nBasic and detailed design packages: SLDs, protection philosophy, layouts, control and EMS functional specifications.\nGrid-connection study reports and PLN submission packages.\nTechnical specifications, RFQ packages and bid evaluation reports.\nFire and hazard risk assessments and safety design basis.\nFAT/SAT and commissioning test procedures and reports.\nPerformance and degradation reports for operating assets.\nIn the first 12 months: an in-house BESS design and procurement standard for the company.\nRequirements\nMinimum 3 years of direct, hands-on BESS and microgrid experience, within a total of roughly 6+ years in power systems, renewable energy or electrical engineering.\nDelivered at least two BESS or hybrid microgrid projects from design through commissioning (ideally ≥1 MWh each), with a clear personal role in sizing, design or commissioning.\nExperience with at least one of: solar-plus-storage hybrid, diesel-hybrid / off-grid microgrid, or C&I behind-the-meter BESS.\nBenefits\n-","description_format":"text","description_chars":3313,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"Indonesia","iso":"ID","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Energy
