Staff Software Engineer

Staff Engineer - Fintech Startup (Remote)

About Us

We're a well-capitalized fintech startup building critical infrastructure for underserved verticals.

We're revenue-generating with two active product lines and have significant customer demand.

The Opportunity

We need a player-coach engineer to take ownership of our reconciliation SaaS platform and scale it from MVP to a production-ready, multi-tenant system serving hundreds of customers. You'll work alongside our founding engineer (who focuses on innovation and new modules) while you build the robust, well-architected foundation our growing customer base requires.

We need someone who can deliver consistently while maintaining high technical standards.

What You'll Do

• Own the core platform: Take our working MVP and architect/build a scalable, multi-tenant SaaS product that can handle massive data volumes
• Ship to customers: Get our reconciliation product across the finish line so we can convert our waitlist into paying customers
• Build for scale: Design infrastructure and architecture that supports hundreds or thousands of customers, not just one design partner
• Bridge the gap: Take prototypes from our innovation-focused engineer and transform them into production-ready features integrated into the core platform
• Set the standard: Establish reliability, security, and compliance practices as we handle sensitive financial data
• Communicate clearly: Translate complex technical concepts for non-technical founders and keep everyone aligned on timelines and progress

What We're Looking For

Must-Haves

• 7-10 years of full-stack engineering experience with proven ability to build 0-1 products from scratch
• Full stack Engineer with Deep expertise in TypeScript and React, AWS and Postgres (our current stack)
• Strong architectural instincts for multi-tenant SaaS systems and large-scale data handling
• Zero-to-one startup experience, you've thrived in ambiguous, high-ownership environments before
• AI-augmented development skills, you know how to leverage AI tools effectively while maintaining code quality and staying close to the codebase
• Security and compliance mindset when handling financial data
• Experience in fintech, payments, or financial services
• Background building reconciliation systems or data-intensive applications
• Track record of taking products from MVP to scale
• Comfort working directly with customers to understand their needs
