While both roles require programming skills, integration engineers emphasize system interoperability, whereas developers focus on application creation.

What are some common challenges a Freelance Integration Software Engineer might face when working with multiple clients?

Freelance Integration Software Engineers often encounter challenges such as managing different client expectations, working with diverse technology stacks, and aligning integration standards across various systems. Since each client may use unique tools and workflows, adaptability and strong communication skills are essential to ensure seamless integration. Additionally, coordinating with remote development teams and adhering to project timelines can be demanding, but these experiences also help build a versatile skill set and professional reputation.

What is a Freelance Integration Software Engineer?

A Freelance Integration Software Engineer is an independent professional who specializes in connecting and combining different software systems so they can work together seamlessly. They are typically hired on a project basis to develop, implement, and maintain integrations between applications, databases, APIs, and other digital services. These engineers ensure data flows smoothly across platforms, streamline business processes, and resolve compatibility issues. Freelancers in this role often work remotely and serve multiple clients across industries.

What are the key skills and qualifications needed to thrive as a Freelance Integration Software Engineer, and why are they important?

To thrive as a Freelance Integration Software Engineer, you need strong programming skills (often in languages like Java, Python, or JavaScript), experience with APIs, and a solid understanding of system integration concepts, typically backed by a degree in computer science or related field. Familiarity with integration platforms (such as MuleSoft, Dell Boomi, or Zapier), cloud services, and relevant certifications (like MuleSoft Certified Developer or AWS Certified Solutions Architect) is highly valuable. Excellent problem-solving, communication, and time-management skills help you collaborate with clients and efficiently deliver solutions in a freelance environment. These capabilities are essential to ensure seamless connectivity between systems, deliver high-quality client solutions, and manage projects independently.

Title:ย AI Integration Developer
Location: Hybrid atย Lemont, IL (50% of the time onsite)
Duration: 6ย Months with possibilities of extension

Only W2 candidates are eligible for this position. Third-party or C2C candidates will not be considered

Description:

  • Client, through the NST division, is seeking an AI Integration Developer contractor experienced with the development, enhancement, and maintenance of AI-assisted workflows supporting scientific data.
  • Some common tasks that will be performed include working with scientific domain experts to understand the location and structure of their data, designing methods to extract/develop metadata, implementing a strong dataset taxonomy to ensure consistency, orchestrating the migration of datasets for computational analysis using approved LLMs, etc.

Scope

  • Client is seeking an engagement with an experienced candidate with qualifications in the listed technologies to aid the NST division and CNM User Facility in work to automate/standardize the process of collecting and storing data for AI training and collaborative ventures.

Objectives

The overall goal of this assignment is to deliver a functional and impactful workflow to aid research scientists across the NST division with data management, including, but not limited to:

  • Identifying location of data and the methodology to determine which data is to be managed through the workflow
  • Filtering, sanitizing, normalizing and/or otherwise preparing the data for storage/sharing
  • Packaging the data with AI-enabling metadata into an HDF5 format that can be used for long-term storage
  • Creating a mechanism to migrate and inventory data for easy retrieval and/or sharing
  • Building an interface/workflow that is accessible and easy to use by the research staff
  • Develop documentation of solutions
  • Construct all components, artifacts, etc. using acceptable tools and techniques, good coding practices and accessible documentation

Tasks and Delivery

  • Three projects have been identified that require data manipulation, sanitization, orchestration and automation.
  • During the first 2-3 weeks, engagements with the scientific domain experts will provide details on understanding their datasets, locations and desired outcomes.
  • Once the details have been identified by the domain scientists, work will begin through an iterative development process to create a compatible workflow, using existing or new tools to achieve the desired outcomes. All tools, software and related materials will require compliance with local cybersecurity and IT standards as well as documentation of operation. Development under revision control is required.
  • Delivery to the domain scientists of an MVP within the first 90-days of the project is expected.
  • The MVP need not address all of the key deliverable outcomes but must demonstrate the core of the workflow desired.
  • Further refinement, refactoring and feature addition is expected beyond the 90-day window.
  • Once the domain scientists have accepted the solution, the candidate will be assigned a new set of domain experts and a new workflow to create.
  • It is expected that each contractor will have no fewer than two active development tasks.

ย  ย  ย  ย Required Background, Knowledge, Skills and Abilities

  • Working knowledge of relevant programming/scripting languages (e.x. python) for automating tasks
  • Working knowledge of revision control systems (e.x. Git)
  • Working knowledge of CI/CD pipelines as implemented in services like gitlab/github for testing and deploying solution changes automatically
  • Familiarity with RESTful web services
  • Strong skills in Linux (Debian and RHEL) CLI administration, development and general use
  • Familiarity with GUI development either through web or python applications
  • Strong written and oral communication skills providing the ability to develop requirements for tasks through interactions with technical experts in the field
