    I'm a native English speaker. I have over 20 years of experience working as an embedded engineer. I was one of the designers/architects of the Microchip PIC18 core. I have worked at Microchip as an engineer in test, design, silicon validation, and applications. I have a Bachelor of Science in Electrical Engineering from Arizona State University, where I graduated with cum laude honors. I'm an expert in both hardware and software, so I'm good at tracking down issues. You may think you have a software issue, but it's a hardware issue or vis-a-versa. I enjoy the challenge of finding and fixing problems. I'm motivated by success, and I enjoy what I do. Work with me, and you'll understand. I bill honestly, and sometimes I'm able to solve a problem in a couple hours. No client has ever disputed my hours worked! I've had a couple clients (2/35) who thought I should not be paid for meetings or getting started on a project. These types of situations don't work out, and it's unfortunate because I want to help them, but won't continue to work with them. The best time to involve me in your project is at the beginning. While I architect your system design, I'll make sure that it meets your performance goals, and will reduce component count and cost. For a successful product, it's important to have a robust hardware and software architecture. I solve problems inside a document, and avoid making multiple PCB revisions. Even though I am in Costa Rica, it is easy to ship development boards to me. My home lab includes: - 100 MHz 4-channel oscilloscope (siglent brand) - 8-channel logic analyzer (saleae - this is what I use to analyze digital communication signals: I2C, SPI, UART, ....) - DC supply - benchtop DMM with 1nA current resolution (great for battery-powered devices) - multiple programmers/debuggers (including PICKIT3). The above tools allow me to understand and properly fix problems. If I don't have the exact equipment you are using, I can often wire something up and be able to develop/test code. I may have a processor on hand that can run your code (higher chance if it is a Microchip microcontroller). I am an expert at using MPLAB/MPLABX, but I am also very comfortable in Code Composer Studio (TI MSP430 series), and Microchip/Atmel Studio. During my time on upwork, I have at times taken the role of tutor and mentor - evaluating projects to look for issues, Assisting with documentation reviews, and also documenting projects from scratch. I have a history of identifying design issues before PCB production, saving money and time. Here are some of the technologies that I've worked with successfully in the past: - capacitive touch sensing - USB communication - Bluetooth communication - graphic displays - LED color mixing (precise color control with no flickering)

Electrical Engineers Hiring FAQ
 




What is electrical engineering?




Electrical engineering is an engineering discipline concerned with applying electricity, electromagnetism, and electronics to practical applications such as computers, robots, and consumer electronics.




How do you hire an electrical engineer?




You can source electrical engineering talent on Upwork by following these three steps:


    

  • Write a project description. You’ll want to determine your scope of work and the skills and requirements you are looking for in an electrical engineer.
    • 

  • Post it on Upwork. Once you’ve written a project description, post it to Upwork. Simply follow the prompts to help you input the information you collected to scope out your project.
    • 

  • Shortlist and interview electrical engineers. Once the proposals start coming in, create a shortlist of the professionals you want to interview. 
    • 



Of these three steps, your project description is where you will determine your scope of work and the specific type of electrical engineer you need to complete your project. 




How much does it cost to hire an electrical engineer?




Rates can vary due to many factors, including expertise and experience, location, and market conditions.


    

  • An experienced electrical engineer may command higher fees but also work faster, have more-specialized areas of expertise, and deliver higher-quality work.
    • 

  • A contractor who is still in the process of building a client base may price their electrical engineering services more competitively. 
    • 



Rates typically charged by electrical engineers on Upwork are:


    

  • Beginner: $12.80 per hour
    • 

  • Intermediate: $35.20 per hour
    • 

  • Expert: $160 per hour
    • 



Which one is right for you will depend on the specifics of your project. 




How do you write an electrical engineering job post?




Your job post is your chance to describe your project scope, budget, and talent needs. Although you don’t need a full job description as you would when hiring an employee, aim to provide enough detail for a contractor to know if they’re the right fit for the project.


Job post title


Create a simple title that describes exactly what you’re looking for. The idea is to target the keywords that your ideal candidate is likely to type into a job search bar to find your project. Here are some sample electrical engineering job post titles:


    

  • Electrical engineer needed for PCB routing or layout with OrCAD
    • 

  • Seeking an electrical engineering consultant for design and code reviews
    • 

  • Electrical engineer needed for an IoT project
    • 



Project description


An effective electrical engineering job post should include: 


    

  • Scope of work: From circuit designs to engineering management, list all the deliverables you’ll need. 
    • 

  • Project length: Your job post should indicate whether this is a smaller or larger project. 
    • 

  • Background: If you prefer experience with certain industries, technologies, or engineering design tools, mention this here. 
    • 

  • Budget: Set a budget and note your preference for hourly rates vs. fixed-price contracts.
    • 



Electrical engineering job responsibilities


Here are some examples of electrical engineering job responsibilities:


    

  • Apply electrical engineering design concepts to product development
    • 

  • Translate customer, technical, and legal requirements into engineering designs
    • 

  • Produce electrical engineering designs and drawings (e.g., PCB routing/layout)
    • 

  • Maintain quality assurance via product testing
    • 



Electrical engineering job requirements and qualifications


Be sure to include any requirements and qualifications you’re looking for in an electrical engineer. Here are some examples:


    

  • Electrical engineering and electronic design
    • 

  • Embedded systems
    • 

  • C and C++ programming languages
    • 

  • Applicable technologies (e.g., IoT, machine learning, consumer electronics)
    • 

  • Working knowledge of microcontrollers, microprocessors, sensors, and other electronics
    •
