Founding Engineer

About Finta Have you tried renewing a driver’s license online? The site looks stuck in 2000, it is confusing and slow. That is how most accounting and tax software still feels. The space is crowded with sales teams who rely on fear to close deals, and the result is bad experiences justified by “compliance.” Finta is changing that. We automate bookkeeping, file taxes quickly and compliantly, and give companies real-time financial metrics. Our goal is simple: to remove the manual, tedious parts of finance so that smart people can focus on hard problems. We raised $2M from Y Combinator, Mercury’s CEO, leaders at Mercury, Brex, and Ramp. Since launching in 2023, we have grown organically through word of mouth and now serve hundreds of paying customers. See what they say at www.finta.com. What you'll do\

• Ship secure, fast, and scalable production code across the stack.
• Collaborate directly with the CEO and designer to deliver complete product features - backend to frontend.
• Work with our modern, opinionated stack: Ruby on Rails, React, Stimulus, Tailwind, Redis, and more.
• Build and maintain banking and accounting integrations with rigorous data-quality and reliability standards.
• Continuously improve testing, observability, security, and deployments on Render.
