Senior Electrical Engineer

Position Type

Full Time, Hybrid, Reports to Fremont NH as needed approximately 1 day per week

We are seeking a full-time Senior Electrical Engineer to support the design, documentation, integration, manufacturing support, and long-term product development of the electrical systems for autonomous aerostat platforms.

This role works closely with a Principal Engineer who owns the overall electrical architecture and system-level integration. The Senior Electrical Engineer will contribute broadly across electrical system design and documentation, including schematic capture, wiring documentation, interface drawings, and controlled design packages in AutoCAD Electrical.

Over time, this role will take increasing responsibility for major power-distribution and related subsystem work, including support for higher-voltage DC applications within the platform. This role will also support manufacturing builds, field operations, troubleshooting, and ongoing product improvement based on test and operational feedback.

This is a hands‑on role for an engineer who is comfortable moving between system design, detailed electrical documentation, integration, implementation support, manufacturing issue resolution, and field troubleshooting. The ideal candidate brings practical experience in electrical power systems, DC power distribution, power electronics, industrial electrical design, mobile electrical systems, or similar applied electrical hardware development, along with strong documentation discipline and product support capability.

Altaeros prides itself on its excellent culture and work life balance, and offers unlimited PTO, medical, dental and vision insurance, 401k plan, as well as life and disability insurance.

• Support the design and ongoing development of the electrical systems for autonomous aerostat platforms
• Work closely with the Principal Engineer to implement system architecture into detailed electrical designs and controlled documentation
• Lead detailed electrical design and day‑to‑day coordination with mechanical engineering to translate electrical requirements, component selections, wiring needs, and layout constraints into a buildable, maintainable, and robust cabinet design.
• Create, update, and maintain:
  • electrical schematics
  • wiring diagrams
  • interconnect documentation
  • panel/interface drawings
  • cable and harness documentation
  • drawing revisions and released design packages in AutoCAD Electrical
• Support development of electrical power‑distribution subsystems and related interfaces
• Assist with design implementation for:
  • Power distribution
  • protection and fault isolation
  • precharge and discharge circuits
  • contactor and relay strategy
  • sensing and monitoring subsystem electrical interfaces
• Define and document interfaces between power hardware, controls, sensors, payload systems, and supporting equipment
• Work with controls and software engineers on interlocks, telemetry, status signals, and safe‑state behavior
• Support lab bring‑up, integration, troubleshooting, and root‑cause analysis
• Support manufacturing builds and field operations with issue resolutions, design clarification, corrective actions and electrical documentation updates based on feedback
• Help improve manufacturability, maintainability, serviceability, and reliability over time Contribute to design reviews, verification planning, and ongoing design improvement as the platform matures
• Support long‑term subsystem ownership and documentation maintenance throughout the product lifecycle

• Familiarity with 1-5 kV DC power‑distribution design considerations
• Experience with systems in the 2 kW to 20 kW range
• Experience with long‑cable, tethered, or remote power‑delivery systems
• Experience in aerospace, defense, UAV, marine, industrial mobile, energy, or other harsh‑environment systems
• Experience with grounding/bonding, connector and termination design, and fielded electrical hardware
  
  Experience with EMI/EMC mitigation in switched power systems
• Experience supporting abnormal‑condition testing, subsystem integration, and field troubleshooting
