About The Position

Altora, a Treetown Tech company, builds power and sensing hardware for unmanned systems, including battery packs, power management, and electronics for aircraft. Technicians at Altora are responsible for turning designs into physical, flight-worthy products, from one-off engineering prototypes to repeatable production builds. The company is seeking a Battery Technician with 3-7 years of hands-on experience who can work independently from drawings and is proficient in both building packs to established processes and assembling first articles for new designs with engineers.

Requirements

Three or more years of experience building electromechanical or electrical assemblies.
Comfortable reading schematics, wiring diagrams, assembly drawings, and a BOM.
Solid hand soldering skills.
Experience with spot welding, crimping, potting, or heat-shrink and insulation work on battery assemblies.
Familiarity with DMMs, power supplies, electronic loads, and battery cyclers.
Ability to work independently and know when to ask for assistance.
Careful with records; meticulous documentation is essential.

Nice To Haves

Battery pack experience (strongly preferred, but strong harness, wire, or precision assembly background with interest in batteries is considered).
IPC J-STD-001 certification (company will pay for certification if not currently held).
Lithium ion or LiPo pack design exposure.
BMS bring-up and configuration.
Knowledge of UN 38.3 or DOT shipping requirements.
Experience with ESD control practices.
Experience with Small UAS or defense hardware.
Basic 3D printing or fixture fabrication skills.
Familiarity with ITAR-controlled work.

Responsibilities

Pack build and assembly: Sort and match cells, spot weld and solder interconnects, build and dress harnesses, install BMS boards and sensing leads, pot and insulate, and close out mechanical assembly according to drawings, BOMs, and released revisions.
Prototype and first-article work: Collaborate with the engineering team on new designs, build the first unit, and provide feedback on buildability. This includes developing fixtures, tooling, and assembly sequences.
Test and verification: Perform capacity, impedance, and cycle checks. Set up and operate cyclers and data acquisition systems, recording results for engineer use.
Documentation: Create work instructions, redline drawings that do not match reality, and maintain accurate serialization and traceability records.
Safety and housekeeping: Own and enforce safe handling, storage, and disposal practices for lithium cells at the workbench.
Support other shop tasks: Assist with cable and harness work, box builds, and general electromechanical assembly as needed.
