Battery Systems Engineer

About Rivian

Rivianis on a mission to keep the world adventurous forever. This goes for the emissions-free Electric Adventure Vehicles we build, and the curious, courageous souls we seek to attract.

As a company, we constantly challenge what’s possible, never simply accepting what has always been done. We reframe old problems, seek new solutions and operate comfortably in areas that are unknown. Our backgrounds are diverse, but our team shares a love of the outdoors and a desire to protect it for future generations.

Join Rivian as a Staff Engineer within the ESS Product Excellence team, based in our Franklin office. In this role, you will drive the sustaining engineering of HV battery systems that are already in production, with a heavy focus on field performance analysis, reliability, and service issue mitigation. You will also play a key role in closing the loop between field/production learning and future product development by providing lessons learned and Design for Manufacturing (DFM) input into next-generation battery designs.

If you are a self-starter with strong battery systems expertise, a passion for diagnosing complex issues in the field, and a desire to shape the design of our future products, we want to hear from you. Help us keep the world adventurous forever.

• Drive sustaining engineering for in production HV battery systems
  • Serve as a technical expert for HV battery packs in series production, with primary focus on field performance, reliability, and serviceability.
  • Act as a key liaison between Service, Reliability, Reman, FAME, Plant ME/PE/Ops, Supplier Quality, and Product Development to drive durable solutions to battery issues observed in the field and at service centers.
  • Maintain a system-level view of how hardware, BMS software, diagnostics, and vehicle usage patterns interact to impact customer experience.
• Lead field performance analysis and service issue mitigation
  • Analyze field, warranty, and ongoing reliability test data to detect trends, characterize emerging failure modes, and quantify risk to customers and the business.
  • Lead root cause investigations for HV battery-related field and service issues (e.g., no-start, reduced performance, diagnostic trouble codes, degradation anomalies), driving permanent corrective and preventive actions.
  • Partner closely with Service Engineering and Technical Support to define, refine, and validate diagnostic strategies, service procedures, and repair paths, ensuring they are robust, efficient, and safe for field execution.
  • Support prioritization and validation of field actions (e.g., service campaigns, software updates, component changes) and clearly communicate risk/benefit trade-offs to cross-functional stakeholders.
• Drive DFM, serviceability, and remanufacturing improvements
  • Provide lessons learned and DFM feedback from field and production back into battery architecture, component selection, and integration strategies for current and future programs.
  • Collaborate with Manufacturing Engineering, Reman, and Supplier Quality to improve build robustness, yield, rework/repair strategies, and remanufacturing flows for HV battery assemblies.
  • Influence design decisions to improve service access, diagnostic coverage, component modularity, and repairability, minimizing customer downtime and total cost of ownership.
• Contribute to new product and control system strategy
  • Partner with the new product design teams to ensure that issues observed on current products inform requirements, architecture, and test strategies for upcoming battery platforms.
  • Work with BMS and Controls Engineers to refine diagnostic and prognostic algorithms, thresholds, and fault handling logic to improve early detection, containment, and customer transparency.
  • Support the development and maturation of cross-functional processes (PD, ME, Ops, Service, Reliability, Reman) that tie together design, manufacturing, and field data to accelerate problem detection and resolution.
• Elevate technical rigor and cross-functional communication
  • Analyze test and field data, author clear technical reports, and present findings and recommendations to engineering leadership and…
