Supercapacitor manufacturer for grid, defense, and data center power resilience
Skeleton Technologies manufactures supercapacitors—energy storage devices that handle power surges, backup, and peak shaving in mission-critical systems. The company is scaling aggressively: 57 open roles with 31 posted in the last 30 days, dominated by senior engineers (28 positions) and manufacturing roles (10), plus a new Head of Finance and Head of People hire. Active projects signal capital and operational expansion: major financing rounds, new factory integration, and ultracapacitor deployment into data center UPS systems. The pain-point list (factory scale-up, throughput, defects, EHS compliance, capital raising) reflects a hardware manufacturer moving from proof-of-concept to high-volume production.
Notable leadership hires: Site Director, Head of Finance, Head of People, Talent Acquisition Lead, Head of Quality
Skeleton Technologies designs and manufactures supercapacitors using proprietary Curved Graphene technology, producing over 4 million cells annually at their Leipzig facility. The company serves grid operators, defense systems, AI data centers, and heavy industrial customers who require power resilience in microseconds—where failure is not an option. Founded in 2009 and headquartered in Tallinn, Estonia, the company operates across multiple geographies (hiring in six countries including the US, Germany, and UAE) and employs over 300 energy storage specialists. Revenue and profitability are not disclosed, but the company is actively fundraising and scaling manufacturing capacity to meet growing demand from the net-zero energy transition and critical infrastructure hardening.
