Freelance Integration Software Engineer information

What is the difference between Freelance Integration Software Engineer vs Freelance Software Developer?

AspectFreelance Integration Software EngineerFreelance Software Developer
Primary FocusDesigning and implementing system integrations and APIsDeveloping standalone applications or features
Required SkillsAPI development, system architecture, integration toolsProgramming languages, application development, UI/UX
Work EnvironmentClient sites, remote, collaborative with IT teamsRemote, independent, project-based
Common CertificationsAPI certifications, cloud platform credentialsProgramming language certifications, software development courses

Freelance Integration Software Engineers focus on connecting different systems and APIs, often working closely with IT teams. Freelance Software Developers create standalone applications or features. 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?

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.

  • Impactful Work: Your contributions will be pivotal in designing and optimizing defense systems that ensure national security and shape the future of space defense.

KBR is seeking a Junior Software Engineer that we can mentor and grow to support the development, integration, and evaluation of software solutions for various RF systems in various operational and signal environments. This role supports control, modeling, simulation, and testing of operationally relevant systems across research and applied DoD programs.

This position requires a strong software foundation, interest in RF system fundamentals, and the ability to work across system, algorithm, and integration boundaries with guidance from senior engineers. The software person will work closely with systems engineers, and at times under the direction of systems engineers and hardware teams to implement, test, and analyze position, navigation, and timing (PNT) capabilities in constructive, laboratory and field environments.

Key Responsibilities

  • Develop, maintain, test, and document software for systems, simulations, and performance analysis environments
  • Implement algorithms and models under guidance, including measurement modeling, error characterization, and estimator behavior under non-ideal conditions
  • Implement and integrate algorithms within software frameworks
  • Integrate software with hardware- and software-in-the-loop (HITL and SITL) and digital twin environments
  • Develop interfaces between software components and external systems
  • Support test planning, execution, and analysis for PNT-focused experiments, demonstrations, and evaluations
  • Collaborate with systems engineers to align system requirements with software designs and implementations
  • Document software implementations, interfaces, and test results to support technical reviews and deliverables

Required Qualifications

  • Bachelor's degree in Computer Engineering, Electrical Engineering, Computer Science, or a related technical discipline
  • 0-2 years of professional experience developing software for technical systems (experience can include internships, co-ops, or academic projects)
  • Programming experience in C#/C++ or Python
  • Experience developing software on Linux and Windows based systems
  • Familiarity with PNT concepts (e.g., Global Navigation Satellite Systems (GNSSs), inertial navigation, timing, sensor fusion)
  • Experience integrating software with complex systems, simulations, or external hardware components
  • Ability to obtain and maintain a U.S. DoD security clearance
  • Participate in team technical interchange meetings to describe technical activities, progress, issues, improvements, and more

Desired Qualifications

  • Academic or project experience with GPS/GNSS signal processing, navigation algorithms, or timing systems
  • Strong verbal and written communications skills
  • Experience with modeling, simulation, or digital twin environments
  • Familiarity with real-time or embedded systems
  • Experience with HITL/SITL test architectures or laboratory integration
  • Experience supporting DoD programs, laboratory R&D, or operational prototyping efforts

Basic Compensation:$80,000 - $100,000 (For Beavercreek, OH Only)
The offered rate will be based on the selected candidate's knowledge, skills, abilities and/or experience and in consideration of internal parity.
