What are Software Developer Contractors?

Software Developer Contractors are professionals hired on a temporary or project basis to design, develop, and maintain software applications for clients or companies. Unlike full-time employees, contractors typically work under a contract for a specific period or for the duration of a project. They may work independently, through agencies, or as part of a consulting firm, and often have specialized skills to meet specific project needs. This arrangement offers flexibility for both the developer and the employer, allowing organizations to scale their technical resources as needed.

What is the difference between Software Developer Contractor vs Software Developer Employee?

AspectSoftware Developer ContractorSoftware Developer Employee
CredentialsTypically requires a relevant degree and technical skills; certifications optionalSame as contractor, often with additional company-specific training
Work EnvironmentContract-based, often remote or on-site for short-term projectsFull-time, usually on-site or hybrid
Employer & Industry UsageCommon in tech firms, startups, consulting agenciesStandard in large corporations, tech companies, and organizations

Software Developer Contractors work on short-term projects, often remotely, with flexible arrangements, while Software Developer Employees are full-time staff with ongoing responsibilities and benefits. Both roles require similar skills and credentials but differ mainly in employment status and work setup.

What are the key skills and qualifications needed to thrive as a Software Developer Contractor, and why are they important?

To excel as a Software Developer Contractor, you need strong programming abilities, problem-solving skills, and a solid understanding of software development methodologies, often backed by a relevant degree or equivalent experience. Familiarity with version control systems (like Git), cloud platforms, and proficiency in languages such as Python, Java, or JavaScript are commonly required, along with certifications like AWS Certified Developer or Microsoft Certified: Azure Developer. Excellent communication, time management, and adaptability set top contractors apart, enabling them to quickly integrate with diverse teams and projects. These skills are essential for delivering high-quality, timely solutions in dynamic and varied client environments.

What are some common challenges software developer contractors face when integrating with existing teams?

Software developer contractors often join projects mid-stream and must quickly adapt to unfamiliar codebases, workflows, and team dynamics. A common challenge is building rapport with full-time staff and understanding company-specific coding standards or tools. Contractors are expected to be proactive in communicating, asking questions, and clarifying requirements to ensure smooth collaboration. Being flexible and open to feedback helps contractors deliver quality work while navigating these initial hurdles.

Title:ย AI Integration Developer

Location: Hybrid atย Lemont, IL (Between 20-40% of the time in Lemont, IL).

Duration: 7 Months

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

Description:
Olient, 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 the 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
  • ย 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.

Required Background, Knowledge, Skills and Abilities

  • A strong working understanding of AI and LLMs

  • Working knowledge of relevant programming/scripting languages (e.x. python) for automating tasks
  • Working knowledge of revision control systems (e.x. Git), CI/CD pipelines as implemented in services like GitLab/GitHub for testing and deploying solution changes automatically
  • ย 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

  • The work will be completed using Government Furnished Equipment (GFE), complete with all required cyber protections, software licenses and tools needed to complete the work under the contract.
  • The device will be made available to the contractor at the outset of the contract, once all cyber-related training is complete.
  • At the completion of the contract term, all provided GFE shall be returned promptly to the client.
