Job description
A Mechanical Engineer at Titan Batteries designs custom battery packs from initial customer discovery all the way through production — owning the full design journey across multiple exciting programs simultaneously while working alongside a collaborative team of engineers.
Responsibilities
- Battery Design: Design custom battery packs — cell layout in series and parallel for target voltage and capacity, welding layout, wire selection, pathing, and connection design. Optimize against weight, volume, thermal, and performance targets.
- Enclosure Design: Determine and design the right enclosure for each application — heat shrink, 3D print, carbon fiber, injection mold. Specify components like membrane switches, LEDs, and BMS as needed.
- Customer Discovery & Requirements: Meet with customers to deeply understand power requirements, energy and power density, thermal environment, charging profile, cycle requirements, and enclosure constraints.
- Cell Selection: Work with the Cell Engineer to identify the right cell for each application — understanding how chemistry, impedance, form factor, and source affect performance.
- BMS Collaboration: Work with the Electrical Engineer to define battery management system requirements based on customer use cases. Communicate requirements clearly without doing the electrical design.
- SKU Sheet Creation: Develop and maintain SKU sheets for each design — documenting required materials and premade components (wiring harnesses, milled parts, enclosures) so procurement and production have everything they need.
- Test Standard Development: Create test standards for each battery design that define how quality is confirmed during and after production, giving quality and production a design-specific benchmark.
- EVT → DVT → PVT Navigation: Guide customers and internal teams through engineering, design, and production validation stages with the right rigor at each.
- Production Partnership: Work closely with the production line when a battery moves into manufacturing. The proximity to production is intentional — use it.
- Peer Review: Participate in peer reviews of designs with fellow engineers, using Titan Battery Engineering Standards (TBES) as the foundation.
- Meeting Discipline: In customer business meetings, support the Strategic Account Manager and defer appropriately. In engineering meetings, lead.
SOFT SKILLS
- Curiosity & Passion: Genuinely excited about battery technology and power systems — ideally because they've been tinkering with this for fun long before it became their job.
- Customer Empathy: Listens deeply to understand what a customer actually needs and translates it into smart design decisions.
- Collaboration: Works well with fellow engineers, account managers, production leads, and customers. Knows when to lead and when to support.
- Meeting Discipline: Understands the difference between an engineering meeting and a business meeting and conducts themselves appropriately in each.
- Ownership: Takes full responsibility for their programs from first call to production.
- Adaptability: Manages multiple programs at different stages simultaneously without losing attention to detail.
TECHNICAL SKILLS
- CAD Proficiency: Strong working knowledge of Fusion 360 or equivalent for battery and enclosure design.
- Mechanical Engineering Fundamentals: Solid grasp of GD&T, materials selection, and basic FEA. Designs for swelling, heat, vibration, and tight tolerances.
- Battery Systems Knowledge: Understands cell types, chemistries, series/parallel configurations, voltage behavior, and impedance. Grows deeper over time.
- TBES Mastery: Expected to master Titan Battery Engineering Standards — the foundation of how batteries are designed and reviewed.
- Cross-Discipline Communication: Works effectively with electrical engineers on BMS requirements and cell engineers on cell selection.
- Production Awareness: Comfortable on the floor — understands how design decisions affect manufacturability.
HIGHLY DESIRED (NOT REQUIRED)
- Personal, hobby, or competition experience with drones, RC aircraft, electric vehicles, robotics, or other DC-powered systems
- Hands-on experience with pouch cell assembly or tab welding
- Familiarity with thermal management
- MATLAB, Simulink, or basic Python for data analysis
- FSAE, Design/Build/Fly, BattleBots, or similar competition team experience
REQUIREMENTS
- Bachelor's degree in Mechanical Engineering
- U.S. citizenship required due to Department of Defense program requirements and security clearance eligibility
