About the role
Description
We are seeking a 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.
Although we list out what we generally look for, we are very likely missing other attributes and skills that you have that could make you a great fit, and are not currently listed. Research has shown this especially applies to women and other marginalized groups, who tend to apply if they check 100% of every box, versus men who apply if they hit roughly 60%. The point we’re getting at, it doesn’t hurt to take a chance and apply!
We are an inclusive employer and value diversity at our company. We do not discriminate on the basis of race, religion, color, national origin, gender, sexual orientation, age, marital status, veteran status, or disability status.
This is a hybrid position. Must be able to commute to Fremont, NH at least 1x week.
Requirements
Key Responsibilities
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.
Support development of electrical power-distribution subsystems and related 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
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
Assist with design implementation for:
Power distribution
protection and fault isolation
pre-charge and discharge circuits
contactor and relay strategy
sensing and monitoring
subsystem electrical interfaces
Required Qualifications
Bachelor’s degree in Electrical Engineering or related discipline
5+ years of relevant electrical engineering experience
Experience in multiple of the following: Electrical power systems, DC power distribution, AC power distribution, power electronics, industrial electrical design, mobile electrical systems, similar applied electrical hardware development
Proficiency with AutoCAD Electrical
Experience creating and maintaining electrical schematics, wiring diagrams, and controlled design documentation
Strong working knowledge of protection concepts including combinations of: Fuses/breakers/disconnects, relays/contactors, current/voltage sensing, pre-charge/discharge, fault response
Strong troubleshooting, root-cause analysis, and corrective-action skills
Ability to work effectively with system, controls, mechanical, manufacturing, test, and operations personnel
Preferred Qualifications
Familiarity with 1-5 kV DC power-distribution design considerations
Experience with systems in the 2 kW to 20 kW range
Experience supporting electrical hardware through concept, detailed design, integration, test, troubleshooting , and design revision.
Experience supporting electrical hardware in manufacturing, production support, sustaining engineering, field troubleshooting, or similar product- support environments.
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
Role Fit
This role is best suited for a hands-on Senior Electrical Engineer who can contribute broadly across electrical system design and documentation while also supporting the realities of build, test, manufacturing, and fielded operation. The successful candidate will not be expected to own the full aerostat electrical architecture. That responsibility remains with the Principal Engineer. This role is
intended for a strong implementation-focused engineer who can help turn system architecture into practical, buildable, supportable electrical hardware and then help improve that hardware over time through manufacturing and field feedback.
What Success Looks Like
Producing clear, accurate, build-ready electrical documentation
Helping convert system architecture into practical, testable hardware designs
Supporting steady progress in subsystem development, integration, manufacturing, and troubleshooting
Resolving build and field issues efficiently and feeding those lessons back into the design
Strengthening the quality, manufacturability, and maturity of power- system implementation over time
Becoming a trusted owner of major electrical design packages and selected power subsystems
Supporting the electrical system throughout development, production support, test, and ongoing product evolution Safety, Standards, and Compliance
Familiarity with electrical safety practices for development, integration, and test of higher-energy electrical systems
Experience working within structured engineering processes that consider applicable standards, safe work practices, and verification requirements
Benefits
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.
