Battery Design Engineer

ALSO•Palo Alto, CA

About The Position

ALSO is an electric mobility company focused on creating innovative, vertically integrated, small EVs. We are seeking Battery Design Engineers (all levels) to architect and build highly integrated electromechanical hardware for micro-mobility battery systems. This role involves full product lifecycle ownership, from concept and prototyping through production launch, ensuring high levels of performance, reliability, and safety. The engineer will be responsible for integrating structural, thermal, electrical, manufacturing, and packaging requirements into a cohesive battery system designed for scalable manufacturing. The role requires comfort with first-principles architecture decisions, detailed CAD work, prototype builds, manufacturing problem-solving, and supplier collaboration.

Requirements

BS in Mechanical Engineering or related field
Ability to bound problems from first principles — thermal, structural, and electrical — with back-of-envelope calcs before reaching for simulation tools
Proven track record designing and releasing complex electromechanical products from concept through production — battery packs, high-density electronics packaging, or similarly constrained assemblies
Fluency with advanced 3D modeling software. CATIA V6 / 3DX preferred
Ability to produce production-quality 2D drawings with rigorous GD&T
Manufacturing process knowledge: welding, stamping, molding, fasteners, adhesives, TIMs, and mechanical joining — with DFM and DFA instincts applied from the first concept, not the last review
Hands-on builder — comfortable in the lab prototyping, debugging, and validating hardware directly, not just reviewing test reports
Working knowledge of how cell behavior, thermal limits, and electrical integration drive pack mechanical architecture; experience with FEA (structural and thermal) tools such as Ansys or Altair

Nice To Haves

Experience designing battery packs for EVs, powersports, micromobility, or other electrified platforms
Experience with automated manufacturing and high-volume assembly systems
Familiarity with lithium-ion cell characterization and selection
Experience working directly with Asian suppliers or contract manufacturers
Experience supporting factory launch or production ramp activities
Familiarity with battery safety and abuse testing standards

Responsibilities

Own complex battery subassemblies or full systems (depending on level) from concept to prototype, validation, and production launch.
Design and integrate battery pack hardware including enclosures, busbars, cooling systems, PCBAs, connectors, HV interfaces, and structural components — balancing thermal, structural, electrical, manufacturing, and packaging constraints simultaneously.
Own top-level assemblies, tolerance strategy, 2D drawings, and engineering release of complex 3D assemblies.
Rapidly down-select concepts through first-principles analysis, hands-on prototyping, and tight test-iterate loops. Comfortable moving from early mockups to production CAD.
Design for scalable manufacturing without compromising performance or safety from day one. Work directly with suppliers and CMs on tooling, process development, assembly strategy, and production ramp. Root-cause manufacturing and field issues across mechanical, thermal, and electrical domains.
