How to apply for Senior Performance Engineer

About ACCURE

ACCURE is a cleantech leader using advanced cloud computing and AI to enhance battery safety and lifespan globally. Their focus on sustainability and deep technical expertise makes them a standout in the energy storage industry, offering the chance to directly impact the renewable energy transition.

About the role

As a Senior Performance Engineer, you'll own the end-to-end battery performance for major grid-scale BESS customers, translating complex analytics into actionable recommendations. This role is critical as the bridge between US customers and European teams, directly shaping the product roadmap with field insights.

A typical day

You'll start by reviewing analytics dashboards for your BESS customers, identifying any performance anomalies. Then, you'll join a call with a US customer to explain a degradation trend and recommend operational changes, followed by a sync with European engineering to share field insights that could improve the platform.

Who ACCURE is looking for

• Deep understanding of lithium-ion battery degradation and safety in grid storage (BESS), with hands-on experience interpreting analytics to drive customer outcomes.
• 5+ years in energy storage or related technical role, preferably with BESS industry experience and a track record of customer-facing technical leadership.
• Excellent communicator who can translate technical data into clear business impact for diverse stakeholders, including non-technical customers.
• Proactive and self-sufficient, comfortable working remotely and bridging time zones between US and European teams.

Tips for this application

• Highlight specific BESS projects you've worked on, including battery chemistry, degradation patterns, and how you improved performance or safety.
• Quantify your impact: use metrics like improved cycle life, reduced downtime, or cost savings from your recommendations.
• Showcase customer-facing experience with examples of translating complex analytics into actionable business insights.
• Tailor your resume to emphasize remote work skills and cross-cultural collaboration, especially with European teams.
• Include any experience with predictive analytics platforms or cloud-based battery monitoring tools.

What to cover in your cover letter

['Your passion for sustainability and battery technology, specifically grid-scale storage.', 'Proven ability to interpret battery analytics and turn them into customer value, with concrete examples.', 'Experience acting as a technical liaison between customers and internal teams, especially in a global context.', "Your understanding of ACCURE's platform and how your background aligns with their mission to enhance battery safety and lifespan."]

Research before applying

• Review ACCURE's blog and case studies for insights into their analytics platform and customer success stories.
• Understand their predictive battery analytics technology and how it differs from competitors like TWAICE or Voltaiq.
• Familiarize yourself with the US grid-scale BESS market, key players, and regulatory environment.
• Look into ACCURE's company culture, remote work policies, and any recent news about partnerships or funding.

Likely interview topics

Based on the job description, expect questions about:

• Describe a time you identified a battery degradation issue from analytics and implemented a solution that improved performance.
• How do you prioritize competing customer requests while feeding back field learnings to engineering?
• Explain a complex battery concept (e.g., capacity fade, SOC estimation) to a non-technical customer.
• How do you stay current with BESS industry trends and lithium-ion battery advancements?
• Tell us about a challenging remote collaboration with an international team and how you ensured alignment.

Common mistakes to avoid

• Being too technical without showing business acumen: always connect your expertise to customer value.
• Underestimating the importance of soft skills: the role requires confident communication and relationship-building.
• Failing to demonstrate genuine interest in sustainability and battery safety beyond just the job description.
