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.

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.

Job description

Software Engineer for AmpliFI Loyalty Solutions, Naperville, IL.

Define the long-term architectural vision and technical strategy for ampliFI's customized credit and debit card loyalty platforms. Lead the design, evolution, and governance of highly scalable, secure, and fault‑tolerant cloud‑native solutions, providing the highest level of technical leadership and strategic direction to cross‑functional engineering teams focused on loyalty,
rewards, and card‑linked programs for financial institutions.

Key Duties and Responsibilities
  • Architectural Strategy & Governance: Define, document, and enforce architectural principles, standards (e.g., SOLID, DRY), and patterns (e.g., microservices, event‑driven architecture) across all engineering teams. Lead the technical planning for major platform evolution.
  • Cloud Platform Leadership (AWS Focus): Act as the highest‑level subject matter expert for ampliFI's AWS ecosystem. Lead the design and optimization of high‑scale data and application architectures utilizing EC2, S3, Lambda, Glue, and DynamoDB to ensure maximum reliability, cost efficiency, and performance for loyalty solutions.
  • System Design & Development Oversight: Oversee the design and implementation of core backend services in Java and related modern frameworks. Provide deep expertise and
    guidance on the integration of REACT front‑end systems with the backend APIs, ensuring optimal performance and security across the stack.
  • Data Architecture Ownership: Design and govern the strategic evolution of data models and performance optimization for both relational databases (PostgreSQL/MySQL) and NoSQL databases (DynamoDB). Define best practices for data warehousing, ETL/ELT (using Glue), optimization, and data security to support complex loyalty program analytics and transactions.
  • Quality & Reliability Engineering: Define and establish company‑wide Test‑Driven Development (TDD) and quality assurance mandates, including automated testing frameworks and CI/CD pipelines (Docker/Kubernetes experience is moved from a "Plus" to a core responsibility at the Architect level).
  • Mentorship & Technical Direction: Serve as a technical mentor and coach for Senior and Software Engineers, resolving the most challenging technical roadblocks. Collaborate with Product Managers to translate long‑term business goals into a detailed, executable technical roadmap.

Position is based out of and reports to Amplifi’s HQ in Naperville, IL, but allows for the option to telecommute from a home office outside of IL (except the following states from which
remote work is not an option for tax reasons: AL, AK, AR, CA, CT, DE, HI, ID, IA, KS, KY, LA, ME, MD, MI, MN, MO MS, NV, NM, NC, ND, OK, OR, RI, SD, VT, WA, WV, and WY.)

Requirements:

Master's degree in Computer Science, Software Engineering, or a related field with three (3) years of experience as a software developer or related occupation in software development.

  • Designing and developing enterprise‑level software systems
  • Developing platform engineering

Also requires demonstrable experience with:

  • Java and associated modern backend frameworks;
  • Designing and deploying applications using the AWS ecosystem (including Lambda, S3, EC2, DynamoDB, and Glue); and
  • Database design and optimization in MySQL or DynamoDB; and experience with containerization technologies (e.g., Docker/Kubernetes).

Salary: $132,000 - $147,000/year
