Electrical Engineer III

Job Description

ABOUT TECNADYNE

Tecnadyne designs and manufactures subsea propulsion systems in San Diego. We are a small, hands-on team where engineers work side by side with production, purchasing, and quality, and where good ideas move from the whiteboard to the build floor quickly.

THE OPPORTUNITY

We are looking for an Electrical Engineer III who wants real ownership. In this role you will own electrical subsystems from requirements through release: architecture, schematics, PCB layout, analysis, prototype bring-up, test, and production support. We are in an active cycle of new hardware development, and you will also help sustain proven legacy designs that our customers still rely on.

Tecnadyne is a mechanically focused company, and electrical engineering is a critical supporting discipline. The work comes in waves: some weeks are design-heavy at your desk, and others are build weeks on the floor supporting testing, integration, and troubleshooting. This role also works closely with customers, joining technical discussions and supporting them after delivery. If you enjoy being the engineer who designs it, builds it, tests it, documents it, and explains it to the customer, this role is a strong fit.

WHAT YOU WILL DO

Own the Full Design Cycle

Own electrical subsystems and assemblies end to end, from requirements definition and block-level architecture through schematic capture, PCB layout, and production release

Design analog, digital, and mixed-signal circuits including motor drives, power distribution, sensor interfaces, embedded control hardware, and communication interfaces such as CAN and RS-485

Select components, connectors, and materials rated for subsea pressure, temperature, and corrosion requirements

Iterate designs based on prototype results, test data, and manufacturing feedback

Analysis & Validation

Perform power budget, power distribution, thermal, signal integrity, fault protection, and worst-case analyses to verify designs before release

Use circuit simulation (for example, SPICE) to validate design intent

Develop and execute test procedures including functional, hipot, and environmental testing

Write clear test reports, analysis summaries, and technical notes that document design intent and findings

Hands-On Build, Test & Troubleshooting

Support prototype and production builds alongside technicians and assemblers on the production floor

Investigate electrical failures and anomalies on new and existing designs and implement practical corrective actions

Use oscilloscopes, multimeters, power supplies, and data acquisition systems for bring-up and troubleshooting

Systems Integration & Cross-Functional Work

Integrate electrical systems with motors, sensors, wiring harnesses, and mechanical packaging

Define and manage electrical interfaces (power, signal, communication) between subsystems

Partner with mechanical engineering on routing, connector access, packaging, and serviceability

Work directly with production, purchasing, and quality to understand their needs and make designs buildable, sourceable, and inspectable

Customer & Technical Support

Participate in and lead customer technical discussions, design reviews, and project status updates

Provide technical support to customers, primarily remote, with occasional travel (up to 5%)

Translate customer requirements into clear electrical specifications and test plans

Documentation, Change Control & Sustaining

Create and maintain schematics, BOMs, wiring harness drawings, and production documentation in Altium Designer

Initiate and process ECOs, evaluating impact on performance, reliability, safety, cost, and schedule

Maintain revision control and configuration management for released designs

Support sustaining work on legacy products, including obsolescence management and board updates

Quality & Continuous Improvement

Author and disposition NCMRs and participate in Material Review Board (MRB) activities

Lead root cause analysis and corrective action on recurring electrical nonconformances

Contribute to internal electrical design standards, templates, and best practices aligned to IPC standards

Help mature engineering practices such as ESD control and high-voltage safety through practical, incremental improvements

WHAT YOU BRING

Required

Bachelor's degree in Electrical Engineering or Computer Engineering

5 to 10 years of electrical engineering experience in a manufacturing environment, including demonstrated ownership of at least one subsystem, board, or assembly from concept through production release

Proficiency in Altium Designer for schematic capture and PCB layout

Strong analog and digital circuit design fundamentals

Experience with embedded hardware and sensor integration

Experience with communication interfaces such as CAN and RS-485

Hands-on hardware experience: prototype bring-up, lab testing, and troubleshooting on the production floor, not design-only

Experience designing and building to IPC standards, including IPC-2221, IPC-7351, IPC-A-610, and IPC/WHMA-A-620

Experience testing hardware to military standards, including MIL-STD-461 and [MIL-STD-810 - confirm]

Experience with ESD control practices and high-voltage safety

Experience performing power analysis, including power budgets and power distribution

Strong technical documentation skills, including test reports and design analyses

Clear, confident communication with customers as well as internal teams

Comfort working on a small, lean team with cross-functional partners, and the confidence to speak up, share technical recommendations, and ask questions

Preferred

Industry experience in subsea, defense, aerospace, or space applications

Motor design, motor drive, or motor integration experience

Thermal and high-power analysis experience, including tools such as Ansys

SPICE modeling experience (for example, LTspice)

Test automation or data analysis using LabVIEW or Python

Track record of introducing process or documentation improvements in a growing organization

HOW SUCCESS IS MEASURED

Electrical deliverables (schematics, layouts, BOMs, harness drawings) released accurately and on schedule

Analyses confirm designs meet performance and reliability requirements before production release

Test procedures developed and executed for all new electrical designs

ECOs initiated and closed on time with full cross-functional coordination

NCMRs dispositioned accurately and promptly, minimizing production delays

Measurable reduction in recurring electrical nonconformances through root cause analysis and corrective action

Electrical designs integrate with mechanical and control subsystems without interface issues

WORK ENVIRONMENT & PHYSICAL REQUIREMENTS

This is an on-site role that splits time between an office setting and the production floor. The standard schedule is Monday through Friday, 8:00 a.m. to 5:00 p.m.

Frequently sit, stand, walk, use hands to handle or feel, reach, stoop, kneel, crouch, talk, and hear

Sit for extended periods and use standard office equipment such as a computer and phone

Handle electrical assemblies and test equipment, and work with energized circuits under established safety practices, including high-voltage testing

Periodically lift and/or move up to 10 pounds

Vision requirements include close vision, distance vision, color vision, peripheral vision, depth perception, and the ability to adjust focus

Reasonable accommodations may be made to enable individuals with disabilities to perform the essential functions of the role.

WHAT WE OFFER
