Battery Storage / Energy Storage Systems Engineer
Sample Resume & ATS Keywords
Storage-specific system design — BMS architecture, thermal/fire-safety design under NFPA 855, and storage-specific interconnection studies under IEEE 1547 — is a narrower, more technical discipline than general power-systems engineering, and OBBBA's preservation of storage ITC/PTC eligibility (even as it cut standalone wind/solar credits) has kept demand strong: 629 live 'Energy Storage Engineer' postings were found on Glassdoor UK alone at time of research. Resumes here need to carry that storage-specific vocabulary precisely, not generic grid-engineering language.

Sample Battery Storage / Energy Storage Systems Engineer resume summary
What a parseable, keyword-complete professional summary looks like for this role:
Energy Storage Systems Engineer with 8 years designing BMS architecture and power-conversion-system (PCS) sizing for utility-scale and commercial battery storage projects. Delivers NFPA 855-compliant thermal and fire-safety designs and IEEE 1547 interconnection studies, and has designed over 400 MWh of storage capacity across LFP and NMC chemistries.
Sample achievement bullets that pass ATS screening
Each bullet follows the pattern recruiters and parsers reward: exact keywords, a specific action, and a quantified outcome.
- Designed BMS architecture and PCS sizing for 22 battery storage projects totaling 410 MWh of capacity across LFP and NMC chemistries.
- Delivered 18 IEEE 1547-compliant interconnection studies for storage-paired projects, achieving first-submission utility approval on 15 of 18.
- Led NFPA 855 thermal and fire-safety design reviews for 12 utility-scale storage sites, resolving all code-compliance issues prior to permitting.
- Reduced average storage-system design-review cycle from 6 weeks to 3.5 by standardizing SCADA integration templates across the engineering team.
- Specified cell chemistry and controls architecture (LFP vs. NMC trade-offs) for 8 projects, improving projected cycle life by 12% on chemistry-optimized designs.
- Managed a $2.4M storage-engineering project budget across 3 concurrent developments, delivering all milestones on schedule.
- Mentored 3 junior engineers on BMS architecture and NFPA 855 compliance, two of whom were promoted to project-lead roles within 18 months.
- Collaborated with EPC contractors on 14 storage builds, cutting field-change-order volume 30% through more detailed pre-construction design packages.

Battery Storage / Energy Storage Systems Engineer resume formatting: do this, not that
Do
- Name BMS architecture and PCS sizing explicitly as storage-specific design work, distinct from general grid engineering.
- Cite NFPA 855 and IEEE 1547 by their exact standard numbers — these are hard, indexed keywords recruiters filter on.
- State the cell chemistries you've designed for (LFP, NMC) since chemistry-specific experience is a real screening differentiator.
- Quantify storage capacity designed in MW/MWh and interconnection studies delivered — both are core scale metrics for this title.
- Distinguish your work from a broader power-systems-engineer role if you're applying against storage-specific postings — use 'storage' and 'BESS' terminology throughout.
Don't
- Don't present this as generic 'power systems engineering' — storage-specific design (BMS, PCS, NFPA 855) is a distinct, narrower discipline that recruiters filter for specifically.
- Don't omit interconnection-study experience — IEEE 1547 storage-specific studies are commonly a named requirement, not implied.
- Don't use vague chemistry language ('battery chemistry experience') — name LFP or NMC explicitly.
- Don't leave project cost or budget figures off senior-engineer resumes — they signal scope of ownership beyond technical design.
- Don't skip mentoring/team-leadership evidence if you have it — many senior storage-engineering postings screen for it explicitly.
