Not every embedded job calls for another full-time hire.
Teams run into work that needs a specific skill, more hands, or steady help for a few months. Hiring takes time. Generic freelance sites can make it hard to find people who have worked on the same kind of problem.
Tell us what needs to get done. We will look for engineers who have worked on similar firmware, boards, and systems.
Common reasons to bring in help
Embedded and electronics work that needs a clear owner.
Examples of work we are looking to support.
02
PCB & Hardware Design
Schematic capture, PCB layout, analog and mixed-signal design, power supplies, high-speed digital layout, and design review.
03
FPGA & High-Speed Interfaces
RTL, FPGA integration and verification, USB, PCIe, Ethernet, high-speed data paths, and performance work.
04
Embedded Linux & BSP
BSPs, bootloaders, device drivers, kernel work, board support, and system bring-up.
Ways to bring someone in
Fractional help or a defined project.
Use fractional time when the work needs continuity. Use a project when the deliverable and end point are clear.
Fractional engineering
Weekly help from an embedded or hardware engineer.
Bring in a firmware, FPGA, PCB, or hardware engineer for a fixed number of hours each week during a board revision, prototype bring-up, validation, a release, or a busy stretch.
- Same engineer week to week
- Hours that can change as work changes
- PCB design, prototype bring-up, or ongoing firmware support
Project-based engineering
An engineer for a defined piece of work.
Use this for a schematic and PCB layout, board review before fabrication, driver, protocol, test fixture, or board debugging job with a clear deliverable.
- Defined deliverable and schedule
- Board redesign, new board bring-up, or a production test fixture
- Remote, onsite, or hybrid work
How it works
Tell us what needs to get done.
-
01
Describe the work
Tell us what the product does, what needs to be designed or debugged, what skills are needed, and any limits on time, budget, location, or hardware access.
-
02
We look for the right experience
We look at the systems and boards involved, the experience needed, availability, hardware access, and confidentiality.

03
Meet a few good matches
We introduce you to a small number of engineers who have the experience the work calls for. No open bidding or pile of generic proposals.
The details of the job narrow the field.

Experience matters
Look for experience that matches the actual work.
Embedded and electronics work is specific. The engineer needs to understand the system, the board, the problem, where the work will happen, and how much ownership the job requires.
We focus on the experience the job calls for. We do not use open bidding, paid placement, or broad freelancer ratings.
