Your mission

To ensure compliance with contractual availability KPIs and optimize service performance, Sungrow is developing a centralized internal monitoring dashboard integrating customer EMS data via the Sungrow Insight Portal

We seek a Lead Developer to design, architect, and build a centralized web-based monitoring platform consolidating all LTSA-contracted ESS sites into one internal dashboard. The platform will:

Aggregate availability data from Sungrow Insight
Reflect site-specific LTSA availability guarantees
Compare real-time data against contractual KPIs
Integrate ticketing for full operational visibility
Deliver actionable, contract-aware insights to service teams

Establish normalization for varying LTSA formulas, site-specific definitions, exclusions, and penalty logic

Availability Logic & Contract Modeling

Build configurable contract logic engine supporting 17–25 year LTSAs

Calculate availability per site, BESS unit, block

Handle thresholds, exclusions

Implement dynamic KPI comparisons (actual vs. guaranteed, rolling monthly/yearly) and early-warning alerts

Dashboard & UX Development

Create single-page web portal with:

Global overview

Drill-down: site → battery unit → inverter → DC block

Real-time availability %

Visual LD-risk warnings

Deliver intuitive UX for remote engineers, NOC, service managers, and LTSA contract managers

Ticketing System Integration

Integrate ticketing API to show open/in-progress/resolved tickets per battery unit

Link availability drops to active tickets

Allow root-cause visibility without leaving the dashboard
