One Park Financial (OPF) is a leading Financial Technology company dedicated to empowering small businesses by connecting them with flexible financing and funding options. Our mission is to provide entrepreneurs with the working capital they need to elevate their businesses. At OPF, we believe in working with high-performing individuals who are ready to play an integral part in our company's expansion — because our success hinges on our people.
Why Join Us? Position Overview
At OPF, we foster a dynamic and inclusive company culture that emphasizes collaboration, innovation, and personal growth. Our team is composed of passionate, driven individuals who are committed to making a difference. Here's what you can expect when you join our team:

Innovative Environment: Work with cutting-edge technology and be part of a team that is constantly pushing the boundaries of fintech

Position Overview
We are looking for an AI-Native Application Software Engineer to help design, build, evolve, and operate a modern cloud-based software platform serving thousands of small and micro-businesses.
This is not a traditional software engineering role where success is primarily measured by how much code an engineer writes. The modern engineer understands the business problem first, frames it precisely, uses AI to accelerate design and implementation, understands how the resulting solution fits into the broader technology ecosystem, and owns whether the solution works for the customer.
AI is an integral part of the engineering process. The engineer uses AI to research, design, generate code, create tests, investigate problems, explore alternatives, document systems, and accelerate delivery—while directing, challenging, and validating AI-generated work.
What We Are Looking For

Deep Subject-Matter Expertise Understands the business and knows what "correct" means
Exceptional Problem Framing Turns ambiguity into clear requirements and solutions
AI Orchestration Uses AI effectively while challenging and validating its output
Systems Thinking & Breadth Understands how UI, applications, APIs, data, cloud, security, and integrations fit together
Curiosity & Continuous Learning Naturally investigates, experiments, learns, and adapts

What You'll Do

Understand customer workflows and translate business needs into software solutions
Turn ambiguous problems into clear requirements, architecture, and acceptance criteria
Use AI as an engineering collaborator for research, design, coding, testing, debugging, documentation, and optimization
Review and challenge AI-generated solutions and remain accountable for the final result
Develop full-stack applications using React, Node.js, JavaScript/TypeScript, and MongoDB
Build and operate cloud applications using AWS, Docker, Kubernetes/EKS, CloudFront, ALB, Route 53, ACM, and related services
Work with multi-tenant websites, customer-owned domains, DNS, SSL certificates, and scalable cloud infrastructure
Build business workflows including websites, lead capture, estimates, invoices, receipts, business email, analytics, and communications
Integrate external services such as Twilio, WhatsApp Business Platform, Amazon Connect, Google Analytics, and other APIs
Diagnose and resolve production issues across the entire technology stack
Automate repetitive engineering processes and continuously improve development and deployment workflows
Learn and experiment with new AI models, tools, APIs, and architectures

Qualifications

Strong experience with modern full-stack application development
Strong React, Node.js, JavaScript/TypeScript, and database experience
Experience with cloud-based applications, preferably AWS
Experience working with APIs, integrations, CI/CD, and production systems
Strong analytical and troubleshooting skills
Ability to work independently and across technical boundaries
Demonstrated ability to use AI effectively in software development
Most importantly, the ability to understand the problem, ask the right questions, and own the outcome

Requirements

3+ years of professional software development experience or equivalent demonstrated capability
Strong JavaScript/TypeScript experience
Strong React experience
Strong Node.js experience
Experience developing REST APIs
Experience with MongoDB or another modern database
Experience with Git and modern software development workflows
Experience developing and debugging production applications
Understanding of cloud-based application architecture
Strong problem-solving ability
Ability to work across the full technology stack
