FinacPlus is a Great Place to Work® Certified organization — a recognition of our people first culture, collaborative environment, and focus on professional growth. We provide high-end virtual business process and technology services to leading global clients across finance, banking, mortgage, research, and data services. At FinacPlus, you’ll work with world-class talent, cutting-edge technology, and international stakeholders — while still enjoying the openness, agility, and career visibility of a fast-growing company.

About Our Client — Toorak Capital Partners

You will be part of a dedicated engineering team supporting Toorak Capital Partners, a leading U.S.-based integrated correspondent lending platform that funds residential, multifamily, and mixed-use real estate loans across the U.S. and U.K. Headquartered in Summit, New Jersey, Toorak’s leadership team brings deep expertise across real estate lending, capital markets, securitization, asset management, and credit.

Role Overview

We are looking for a high-impact Full Stack Software Engineer who can build, scale, and own modern fintech platforms end-to-end. You will work on mission-critical mortgage and financial systems, contributing to both frontend experience and backend architecture in a cloud-native, production-scale environment.

This role is not limited to feature delivery—you are expected to own systems, influence architecture decisions, and drive performance, scalability, and reliability across the stack.

• Design, develop, and own end-to-end full stack applications using React.js and Node.js in a production environment
• Translate complex product and UX requirements into high-performance, scalable, and maintainable systems
• Build and maintain microservices and micro-frontend architectures with clear service boundaries and modular design
• Optimize applications for performance, latency, and scalability, including frontend rendering and backend throughput
• Collaborate closely with Product, UX, QA, and DevOps to ensure high-quality, production-ready releases
• Contribute to and improve CI/CD pipelines, ensuring reliable and repeatable deployments
• Implement observability practices (logging, monitoring, tracing) for production systems
• Ensure adherence to secure coding practices, data protection, and financial system compliance requirements
• Actively participate in code reviews, design discussions, and technical decision-making

Core Technologies (Must-Have)

• Strong hands-on experience with React.js (Hooks, state management, performance optimization)
• Strong fundamentals in HTML5, CSS3, and modern frontend architecture
• Proven experience building microservices-based systems
• Hands-on implementation of micro-frontend architecture
• Strong understanding of:
• Distributed systems
• Scalability patterns (horizontal scaling, caching, async processing)
• Ability to design modular, loosely coupled, and resilient systems
• Experience with GCP / AWS (GCP preferred) in production environments
• Familiarity with:
• Storage and networking
• CDN integrations
• Understanding of cloud-native design principles

DevOps & CI/CD

• Hands-on experience with CI/CD pipelines (Jenkins, GitHub Actions, or similar)
• Experience with build, release, and deployment workflows
• Exposure to containerization (Docker preferred) is a plus

Databases & Storage

• Strong experience with relational databases (PostgreSQL / MySQL)
• Working knowledge of NoSQL databases (MongoDB / Firestore / DynamoDB)
• Ability to design scalable data models and optimize queries

APIs & Integrations

• Strong experience building and consuming RESTful APIs
• Understanding of API security, authentication (OAuth/JWT), and rate limiting
• Experience integrating with third-party services and financial systems

Observability & Monitoring

• Exposure to logging, monitoring, and debugging tools (e.g., ELK, Datadog, Cloud Monitoring)
• Ability to analyze production issues using metrics and logs

Security & Best Practices

• Understanding of:
• Secure coding practices
• Data protection and privacy
• Experience in building secure financial or regulated systems is a strong advantage
• 4–7 years of strong full stack development experience in product or SaaS environments
• Proven experience working on production-scale applications (not just projects or POCs)
• Demonstrated ability to handle both frontend and backend ownership
• Experience working in cloud-native, distributed systems
• Only worked on support / maintenance / L1-L2 roles
• Experience limited to academic projects or small-scale applications
• No exposure to system design, scalability, or production environments

What Makes a Strong Fit

• Has owned features or systems end-to-end in production
• Demonstrates clear understanding of scalability and performance trade-offs
• Experience improving:
• System performance
• Cost efficiency
• Reliability / uptime
• Comfortable working in fast-paced product environments with global stakeholders
• Shows engineering depth, not just framework familiarity
• Strong problem-solving mindset with ability to debug complex real-world issues
