How to Apply for (Senior) BESS Engineer - Americas
at TWAICE
🏢 About TWAICE
TWAICE is a leader in battery analytics, dedicated to extending battery life and performance for a sustainable energy future. Their unique focus on BESS optimization and their role as a trusted partner for major energy projects make them an exciting place to drive real impact in the renewable energy transition.
About This Role
As the primary technical contact for US and Americas customers, you'll lead onboarding, performance analysis, and KPI validation for large-scale BESS projects. Your work directly improves battery longevity and operational efficiency, bridging customer needs with product development.
💡 A Day in the Life
A typical day might start with a call with a US customer to review sensor data quality issues, then diving into Databricks to configure KPIs for a new project. Afternoon could involve analyzing performance trends, documenting feedback for product teams, and preparing training materials for O&M leads.
🚀 Application Tools
🎯 Who TWAICE Is Looking For
- A BESS performance or O&M engineer with deep hands-on experience in commissioning, sensor data analysis, and troubleshooting lithium-ion battery systems.
- Proficient in Python for analytical tasks (e.g., data quality checks, performance metrics), with Databricks experience a strong plus.
- Strong communicator who can translate technical findings for both engineering teams and commercial stakeholders, building trusted relationships.
- Proactive problem-solver who identifies product gaps and collaborates with product/engineering to drive improvements.
📝 Tips for Applying to TWAICE
Highlight specific BESS projects you've worked on, detailing your role in commissioning, sensor configuration, or performance analysis.
Mention any experience with Databricks or similar data platforms; if not, show Python proficiency with examples of battery data analysis.
Emphasize your understanding of lithium-ion degradation mechanisms and how you've applied that knowledge to improve battery life.
Tailor your resume to show direct experience with Single Line Diagrams, sensor hierarchies, and KPI rollout for BESS.
In your cover letter, reference TWAICE's product (e.g., battery analytics software) and explain how your background aligns with their mission.
