📋 Description

• Serving as primary technical contact for US and Americas customers, building relationships with both technical and commercial stakeholders. • Supporting pre-sales alongside Sales and Solution Engineering: technical discovery, data-readiness assessments, and architecture discussions. • Leading technical onboarding: reviewing Single Line Diagrams, mapping sensor hierarchies (cell to string to rack to enclosure to PCS to system), and configuring sensor specifications in Databricks before KPI rollout. • Managing KPI rollout and validation: releasing TWAICE KPIs, and diagnosing sensor data quality issues, insufficient cycling data, and aggregation errors. • Leading performance analysis during commissioning and augmentation: interpreting capacity test results, flagging anomalies (cell imbalances, voltage spread issues, RTE gaps), and producing executive-ready outputs. • Surfacing recurring product gaps and customer feedback to Product and Engineering. • Running platform training for performance engineers, O&M leads, and asset managers. • Up to 25% travel for customer meetings and on-site visits across the Americas.

🎯 Requirements

• BESS industry experience is required. • You have worked as a performance engineer, systems engineer, or O&M engineer. • You know what happens inside a BESS project from commissioning through the first year of operation. • Degree in Engineering, Science, or a related field, or equivalent demonstrated BESS experience. • Comfortable with Python in an analytical context: processing sensor data, validating signal quality, debugging anomalies. • Databricks experience is a plus. • Deep knowledge of lithium-ion battery behavior, degradation mechanisms, capacity fade, DC internal resistance, SoC estimation, and cell voltage/temperature imbalances. • Familiarity with BESS data flows and ingestion protocols (Modbus, IEC-104, OPC-UA, REST API, SFTP). • Working knowledge with US wholesale power markets and ISOs/RTOs (CAISO, ERCOT, PJM, MISO, SPP, ISO-NE, NYISO). • Clear communicator, strong English required; Spanish is a plus for broader Americas coverage. • Organized, customer-focused, and comfortable in a fast-moving startup.

🏖️ Benefits

• Flexible Working: We trust you to get the job done. • Remote-first with autonomy on how and where you deliver. • Everyone comes together for our annual kick-off at Munich HQ. • Equity Participation: Every employee is offered a stock-option plan so you can share in TWAICE’s success. • Perks: Health coverage, 401(k), team offsites twice a year.
