What does a freelance Amazon software engineer do?

A Freelance Amazon Software Engineer is an independent contractor who designs, develops, and maintains software solutions for clients utilizing Amazon's technologies and platforms, such as AWS (Amazon Web Services). They may work on a variety of projects, including building cloud-based applications, optimizing existing systems, or integrating with Amazon APIs. This role requires strong programming skills, familiarity with Amazon’s services, and the ability to manage projects independently while collaborating remotely with clients.

What are the key skills and qualifications needed to thrive as a freelance Amazon software engineer?

To thrive as a Freelance Amazon Software Engineer, you need strong programming skills (such as Java, Python, or C++), experience with cloud platforms like AWS, and a solid understanding of software development principles, typically supported by a relevant degree or equivalent experience. Familiarity with Amazon Web Services (AWS) tools, APIs, version control systems like Git, and possibly certifications like AWS Certified Developer are highly valuable. Excellent problem-solving, self-management, and communication skills help you manage projects independently and collaborate effectively with clients remotely. These skills ensure you can deliver robust, scalable solutions that meet client needs while maintaining efficiency and quality as an independent contractor.

How does a freelance Amazon software engineer typically collaborate with remote teams and stakeholders?

As a Freelance Amazon Software Engineer, you’ll often work with distributed teams across different time zones, requiring clear communication and effective use of collaboration tools like Slack, Jira, and GitHub. Regular virtual meetings and status updates are common, and you may be expected to document your code extensively to ensure smooth handovers. Building rapport and maintaining transparency with both technical and non-technical stakeholders is key to project success. Proactive communication and adaptability are essential for navigating shifting project requirements and feedback.

Job description

Leidos has an exciting opportunity for an Exploitation Specialist/GDAT Software Engineer to join our team in St. Louis, MO.

This work requires skills and knowledge to modernize applications to facilitate production operations for customer.

These resources will not be making major performance enhancements on GDATM Tool. Instead, they shall provide the necessary skills and experience to support customer in completing minor improvements in software functionality necessary to support routine maintenance.

Primary Responsibilities

Support end-users and ensure they possess the necessary capabilities to fulfill mission-critical objectives. These objectives are multifaceted, as the GDAT-M team not only supports customer goals but also those of ASG collaborators, other entities, and co-producer contractors. These roles involve sustaining and deploying the Geospatial Data Analysis Tool-Modernized (GDAT-M) application, developed by the customer. GDAT-M serves the customer, ASG collaborators, and co-producer contractors. It is a leading desktop application responsible for geo-positioning and validation of national products. The GDAT-M team is focused on delivering GEOINT content from relevant sensors. The goal is to modernize tools, enabling customers to transition from MS-Access to PostgreSQL databases, following a bi-annual release cycle.

At Leidos, we don't want someone who "fits the mold"-we want someone who melts it down and builds something better. This is a role for the restless, the over-caffeinated, the ones who ask, "what's next?" before the dust settles on "what's now."

If you're already scheming step 20 while everyone else is still debating step 2... good. You'll fit right in.

Original Posting:January 13, 2026

For U.S. Positions: While subject to change based on business needs, Leidos reasonably anticipates that this job requisition will remain open for at least 3 days with an anticipated close date of no earlier than 3 days after the original posting date as listed above.
