Job Description - (Senior) BESS Engineer - Americas

About the role

The energy transition runs on batteries. As renewable energy reshapes the global power system, batteries are taking center stage. Making them reliable, safe and scalable are the defining challenges of the energy transition. At TWAICE, we build software that turns battery data into insights, so that we can help the world reach net zero faster.

As a (Senior) BESS Engineer at TWAICE, you sit at the intersection of customer-facing engineering and battery performance analysis. You will be TWAICE’s primary technical point of contact for asset owners, O&M teams, and developers across the Americas. The role spans pre-sales through in-life support: technical discovery, data-readiness assessments, customer onboarding, KPI rollout, and performance analysis for commissioning and augmentation events.

Your daily business will involve

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

Your profile

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

Please consider that the requirements are not listed in order of relevance. We know that it is close to impossible to fulfill all requirements. If you feel that you can make a valuable contribution, we’d be delighted to receive your application regardless.
