Full Stack Developer - Senior / Lead

Remote (India)

About FinOpSys 

At FinOpSys, we’re building a modern SaaS-platform that automates financial operations workflows for small and mid-sized U.S. businesses. Our mission: let businesses focus on growth while we handle their financial operations with precision, AI integration and scalability.

Position Summary

We are hiring a Senior Full-Stack Developer who can take ownership of end-to-end design and development across multiple customer-facing systems. While this is a full-stack role, we prefer someone with a stronger backend foundation, solid system thinking, and excellent database design skills. If you have industry experience (fintech, accounting, bookkeeping, SaaS) that’s a strong plus. 

You will work directly with the CTO, guide developers, maintain execution quality, and help shape the engineering culture as the company grows.

Working Hours: US Pacific timezone overlap required (5-6 hours)

  • Provide code reviews, technical guidance, and unblock team members 

  • Participate in architectural discussions and long-term planning

  • Use AI tools effectively to speed up development, debugging, documentation, and iteration 

  • Maintain quality, consistency, and testing discipline across assigned modules 

Required Skills & Competencies

  • 5+ years of full-stack development experience 

  • Strong backend fundamentals (Node.js preferred; flexible if strong in another backend language and can adopt quickly) 

  • Strong understanding of relational database design, normalization, and optimization 

  • Ability to think about performance, scalability, and efficient query design 

  • Proficiency in JavaScript/TypeScript or ability to pick it up quickly 

  • Experience with modern frontend development (React or similar) 

  • Ability to design structured APIs and clean application layers 

  • Experience integrating with AI/LLM services or willingness to adopt them quickly 

  • Ability to leverage AI tools (coding assistants, debugging, documentation, schema design exploration) to achieve high-quality output faster 

  • Exposure to Infrastructure-as-Code (IaC) tools (Terraform, CloudFormation, or similar) for basic environment setup and service configuration 

  • Clear communicator with strong ownership and proactive problem-solving 

Nice to Have

  • Experience with low-code / no-code tools like Bubble.io (helpful but not required) 

  • Familiarity with n8n, Retool, Zapier, or workflow automation 

  • Exposure to cloud environments (AWS preferred) for deployments and service configuration 

  • Experience working in early-stage teams 

  • Experience implementing multi-tenant SaaS patterns and ensuring secure data separation 

  • Experience designing workflow-heavy or approval-based systems 

Who Will Thrive 

  • Someone comfortable working with autonomy and clarity 

  • Someone who communicates clearly, works reliably, and maintains strong follow-through 

  • Someone who can think across the stack but is naturally stronger in backend logic 

  • Someone who cares about clean architecture, meaningful schema design, and maintainable code 

  • Someone who likes fast pace, responsibility, and direct collaboration with leadership 

  • Someone with strong enthusiasm, work ethic, and communication clarity 

  • Someone who can take high-level requirements and turn them into clear technical designs, data models, and actionable tasks without needing constant supervision 

Why Join FinOpSys 

  • High-impact role working directly with the CTO 

  • Ability to influence product and engineering from early stages
