Senior Full-Stack Engineer

Ready to architect the next generation of point‑of‑sale financing technology?

At Digni Fi, you’ll build the intelligent systems powering real‑time financing decisions for over 2,000 automotive partners nationwide. Our engineering team designs scalable platforms that process thousands of financing applications daily, leveraging cutting‑edge machine learning, cloud‑native architecture, and seamless API integrations that transform how consumers access automotive financing.

You’ll tackle fascinating technical challenges: building millisecond‑response credit decisioning engines, designing fault‑tolerant payment processing systems, and creating intuitive interfaces that work seamlessly across dealership workflows. Working with modern tech stacks—including cloud services, containerized microservices, and advanced data pipelines—you’ll have the autonomy to architect solutions that directly impact our partners’ revenue growth and customer satisfaction.

This isn’t just another fintech engineering role—you’re building the infrastructure that helps working families afford critical car repairs they couldn’t otherwise access. Every system you design, every optimization you implement, directly enables someone to keep their vehicle running and maintain their livelihood.

Join us in engineering solutions that make automotive financing more accessible, transparent, and immediate than ever before.
