Senior Software Engineer
Chargebacks911 is a fast-growing global FinTech based in Clearwater, FL. Our Software Engineering team is building systems that solve everything related to the growing problem of Chargebacks & Credit Card Disputes. Our pace is high, our problems are real, and our technology choices evolve as the business evolves.
We believe that great engineers are not defined by the logos on their résumé, but by their ability to reason about systems, read and write code fluently, and adapt quickly as tools change. With modern AI-assisted development, judgment, architectural taste, and sheer reps of programming matter more than memorizing frameworks.
The Role
We are looking for Senior Software Engineers—engineers who can drop into any team, understand the problem space quickly, and make meaningful contributions regardless of the specific technology in use.
You may work across frontend, backend, and infrastructure boundaries depending on the needs of the business. React on the frontend and Node.js or PHP on the backend are common in our stack today, but experience with those exact tools is a plus, not a requirement.
This role is ideal for engineers who have:
Written a lot of code
Read even more code
Refactored systems that were already in production
Developed a strong sense for what good looks like
What You’ll Do
Design, build, and evolve production software systems with a focus on clarity, scalability, and maintainability
Quickly ramp into unfamiliar codebases, frameworks, or languages and contribute effectively
Make sound architectural decisions and articulate tradeoffs clearly
Collaborate across teams, providing technical leadership without rigid ownership boundaries
Use AI-assisted coding tools (e.g., Cursor, Windsurf, GitHub Copilot) as force multipliers—not crutches
Review code with a focus on correctness, simplicity, and long-term cost
Help raise the engineering bar through example, feedback, and mentorship
What We’re Looking For
Must-Haves
7+ years of professional software engineering experience (or equivalent reps)
Demonstrated ability to learn new technologies and codebases quickly
Strong fundamentals in software design, data structures, and system architecture
Proven experience working in large or long-lived codebases
Excellent code reading skills—you understand code you didn’t write
Comfort working across the stack, even if you have a primary strength
Openness to and comfort with AI-assisted development tools
Clear written and verbal communication skills
Nice-to-Haves (Not Required)
Experience with React, Node.js, or PHP
Experience in FinTech, large scale financial systems or enterprise data sets
Experience scaling systems under real-world constraints
Prior technical leadership or mentorship experience
How We Think About Engineering
Taste beats trivia: We care more about why you chose a design than whether you remember an API.
Reps matter: Time spent coding, debugging, refactoring, and reviewing compounds.
AI is table stakes: We expect engineers to leverage modern tools thoughtfully.
Flexibility wins: Teams change, problems change, and strong engineers adapt.
