hace 2 semanas

About Us

We’re a newly funded B2C FinTech startup on a mission to democratize private banking. Our platform combines AI-driven intelligence with the expertise of human financial advisors to deliver holistic, personalized wealth management advisory — making high-quality financial advice accessible to a wider audience than ever before.

Backed by leading investors in our Pre-Seed round, we’re building the product foundation that will power a new generation of intelligent financial advisory.

The Opportunity

We’re looking for a Senior Backend Engineer to join as one of the early technical hires and play a key role in developing our core advisory engine — the heart of the product. You’ll work hand-in-hand with the Founders to architect, build, and scale systems that are secure, modular, and ready for growth.

This is an opportunity to have outsized impact, influence product and technical decisions from day one, and help shape the future of wealth management.

What You’ll Do

  • Design and develop scalable, maintainable backend systems to power our AI-human hybrid advisory engine

  • Write clean, well-documented, and testable code following SOLID principles and Domain-Driven Design (DDD) best practices

  • Collaborate in system architecture, service design, and API development

  • Implement robust security, data integrity, and performance strategies in a financial environment

  • Contribute to setting engineering standards and help build a culture of technical excellence

  • Participate in code reviews, technical discussions, and team decision-making


What We’re Looking For

  • 5+ years of experience in backend development with a strong track record of designing and implementing scalable, maintainable systems

  • Deep understanding of software architecture, system design, and best practices for building reliable, scalable services

  • Proficient in modern backend languages and frameworks—Node.js experience is a big plus

  • Ability to write clean, testable code following SOLID principles and Domain-Driven Design (DDD) practices

  • Comfortable working in a fast-paced, collaborative, and product-driven startup environment

  • Excellent communication and problem-solving skills


Bonus Points

  • Experience in FinTech or regulated environments (e.g. banking, insurance, wealth management, etc)

  • Familiarity with AI/ML integrations or recommender systems

  • Knowledge of security and compliance standards in financial services

  • Experience working in early-stage startups or as a founding engineer


What We Offer

  • A front-row seat in a mission-driven FinTech startup reinventing how people manage wealth

  • The chance to build and own systems from the ground up

  • A collaborative, high-trust environment where your voice matters

  • Competitive salary

  • Hybrid office/remote policy


If you're excited about creating technology that empowers people to take control of their financial futures, we'd love to meet you.
