Freelance Fintech Software Engineer information

What is a freelance fintech software engineer?

Freelance Fintech Software Engineers are independent professionals who specialize in developing, maintaining, and improving software solutions for the financial technology (fintech) industry. They work on a contract or project basis with clients such as banks, startups, or payment companies, building secure, scalable applications like payment gateways, trading platforms, or digital wallets. Their responsibilities often include coding, testing, integrating APIs, and ensuring compliance with financial regulations. Freelance fintech engineers must stay updated with industry trends, security practices, and evolving technologies to meet the unique needs of financial clients.

How do freelance fintech software engineers typically collaborate with clients and cross-functional teams?

Freelance Fintech Software Engineers often work remotely, but strong collaboration is still essential. They usually communicate with clients, product managers, and designers through regular video meetings, project management tools, and messaging platforms to clarify requirements and provide updates. It’s common to participate in code reviews, agile sprints, and documentation processes to ensure seamless integration with existing systems and compliance with financial regulations. Clear communication and proactive feedback help maintain trust and deliver high-quality solutions, even when working independently.

What are the key skills and qualifications needed to thrive as a freelance fintech software engineer, and why are they important?

A Freelance Fintech Software Engineer must have strong programming skills (such as Python, Java, or C#), a solid understanding of financial systems, and experience with secure software development, typically supported by a degree in computer science or a related field. Familiarity with fintech-specific tools and frameworks (like blockchain platforms, payment APIs, or cloud platforms such as AWS), as well as relevant certifications (e.g., AWS Certified Developer or Certified FinTech Professional), is often required. Outstanding problem-solving abilities, communication skills, and the ability to manage projects independently set top freelancers apart. These competencies are crucial for delivering robust, secure, and innovative solutions in the rapidly evolving fintech sector.

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

Work EnvironmentIndependent, project-based, often remote or freelance contractsEmployed by a company or fintech firm, working in office or remote teams
Employer & Industry UsageServes multiple clients across fintech projects, flexible engagementsWorks within a fintech company or startup, focused on product development

While both roles involve software development in fintech, a Freelance Fintech Software Engineer works independently on various projects, whereas a Fintech Software Developer is typically employed by a company to develop specific products or services.

How to get into fintech as a freelance fintech software engineer?

To become a freelance fintech software engineer, develop strong programming skills in languages like Python, Java, or C++, and gain experience with financial APIs, blockchain, or payment systems. Building a portfolio of relevant projects and obtaining certifications such as CFA or financial technology courses can enhance credibility.

Fullstack Engineer

Koalafi

Arlington, VA • On-site

Full-time

Re-posted 4 days ago


Job description

Job Summary:
Koalafi is a company focused on transforming the financing experience for non-prime consumers. They are seeking a Fullstack Engineer to build and integrate a new Non-Prime Installment Loan product, which involves developing microservices, REST APIs, and collaborating with a product team to enhance customer financing options.
Responsibilities:
• Implement microservices and event-driven workflows to integrate Koalafi's systems with a third-party loan servicing platform
• Build and maintain REST APIs that support loan origination, payment processing, and customer servicing operations
• Navigate and contribute to existing internal services where the NPIL product intersects with current Koalafi systems — reading unfamiliar code, understanding its intent, and making clean, well-scoped changes
• Develop frontend components in React/TypeScript to support customer-facing and internal tooling as needed
• Write code that is testable, observable, and built to last — not just built to ship
• Work closely with the Tech Lead on system design and integration architecture
• Partner with Product and Compliance to understand requirements and translate them into reliable, compliant implementations
• Participate in code reviews — both giving and receiving feedback with the goal of raising the bar, not just checking a box
• Engage actively in sprint ceremonies: planning, retros, standups — contribute to the team's rhythm, not just your own ticket
• Implement monitoring and alerting at integration points so issues surface before customers notice them
• Support audit logging and data reconciliation requirements inherent to a regulated financial product
• Identify and flag technical risk early — bad news early is always better than bad news late
• Leverage AI development tools to move faster and stay consistent with team patterns
Qualifications:
Required:
• 2–4 years of professional software engineering experience
• Hands-on experience building backend services in Golang
• Working knowledge of REST APIs, HTTP/JSON patterns, API authentication including bearer tokens and OAuth flows and API Testing tools like Postman, HTTPPIe
• Experience building or contributing to frontend applications; React/TypeScript preferred
• Familiarity with AWS, Kubernetes, and cloud-native deployment patterns
• Familiarity with observability concepts and tools like Dynatrace
• Familiarity with AGILE/Scrum principles, ceremonies and JIRA
• Solid testing instincts — unit, integration, and contract testing aren't afterthoughts for you
• Comfort navigating and contributing to unfamiliar codebases — not just greenfield builds
• Strong communication skills: you can explain what you're building and why, not just how
• Location Requirement: This position requires regular in-person attendance at one of our two office locations (Richmond, VA or Arlington, VA). Candidates must already be located within a commutable distance to either location, as relocation assistance is not available at this time
Preferred:
• Experience with event-driven or asynchronous messaging patterns
• Background in fintech, lending, payments, or other financial services
• Familiarity with third-party financial platforms (LoanPro, Peach, Amount, or similar)
• Experience with feature flags and gradual rollout strategies
• Interest in leveraging AI tools to accelerate development velocity
• Secret Management using AWS Secret Manager
Company:
Koalafi offers omnichannel financial products that help merchants and consumers succeed. Founded in 2014, the company is headquartered in Glen Allen, USA, with a team of 201-500 employees. The company is currently Growth Stage.
