About Treetown Tech
Treetown Tech is an engineering and manufacturing company that takes ideas from a napkin sketch through low-rate production, under one roof. Our teams work side by side across mechanical, manufacturing, electrical, software, and battery engineering to design, build, and manufacture hardware for clients ranging from early-stage hardware startups to established aerospace, battery, and semiconductor companies.
Our team has built and shipped hardware behind UAV flight controllers, battery management systems and charging electronics, semiconductor test equipment, and industrial automation and control systems. If you like seeing a design go from a schematic to a working prototype to something that ships, you'll find real variety here.
About the Opportunity
Treetown Tech is looking for an on-site, experienced, full-time Electrical Engineering Technician. This is a hands-on role for someone who is experienced in building real hardware alongside diverse engineering teams.
You'll fit well here if you keep an organized work area, are deeply committed to cooperation and communication, take safety and quality seriously as a matter of habit rather than compliance, and are comfortable digging into a variety of tasks in a fast-paced, multi-disciplined team.
Treetown Tech offers competitive compensation and benefits including healthcare, IRA matching, and generous PTO and sick time.
What You'll Do
Solder & Assembly
- Perform PCB assembly including surface-mount and through-hole soldering, using solder pencils, hot-air reflow, and reflow ovens.
- Handle general and rework soldering across a mix of straightforward assembly runs and more detailed, time-critical rework or design changes.
Wiring & Harness Building
- Build wiring harnesses and wire for AC and DC circuits, including industrial automation wiring, wire end termination/crimping, and connector assembly.
- Read schematics, wiring diagrams, and eCAD to build to print, working collaboratively with the designer or engineer on the project.
Electrical Testing
- Support electrical test activities such as charge/discharge testing and end-of-line test.
- Collect and record test data accurately and diligently.
- Follow and complete internal quality control documentation.
Quality & Safety
- Keep your work area organized and follow safety protocols and quality standards on every task.
- Flag issues or quality concerns as they come up rather than working around them.
PLC Cabinet Wiring (bonus capability – not required)
- PLC cabinet wiring and fluency with wiring diagram/schematic conventions used in cabinet builds.
- Fabrication and assembly of PLC cabinets.
- PLC cabinet testing and quality control.
What We’re Looking For
- Electrical shop experience, and comfort working in a fast-paced, multi-disciplined team.
- Ability to communicate effectively, both written and verbally, with coworkers.
- A habit of showing up on time and staying on task throughout the day.
- Comfort with ambiguity, and the judgment to know when to ask for help rather than guess.
- Eagerness to roll with frequent design changes that come with R&D and prototypes.
- Openness to receiving direction and training from others, and to navigating changing priorities.
- Genuine care for the wellbeing of the people around them. A true team player.
- Driven to reduce cost, complexity, and time for themselves and those around them.
- Ability to lift loads of up to 50 lbs.
Additional Nice to Haves, but Not Required
- Soldering/rework certification (IPC or similar).
- Prior troubleshooting experience on machine or PLC electrical systems.
- Experience with small-scale line manufacturing.
- Experience with parts ordering and inventory.
- Forklift certification.
- Experience coordinating directly with external vendors.
