About DreamFi

DreamFi is building the future of accessible digital banking—fast, intuitive, and secure. We’re leveraging cutting-edge technology and Banking-as-a-Service (BaaS) platforms to launch financial products that help people take control of their money without the complexity of traditional banks.

• Collaborate closely with product, design, and leadership to translate business needs into technical execution
• Mentor and support engineers through code reviews, guidance, and career growth
• Scale and maintain infrastructure using modern DevOps practices (IaC, CI/CD, monitoring)
• Help define and support hiring efforts to grow a world-class engineering team

Desired Skills & Experience:

• 5+ years of professional experience in software engineering, with 1–2+ years in a leadership role
• Deep backend experience with Golang in production environments

• Experience integrating BaaS or third-party fintech APIs
• Proficiency in PostgreSQL, including schema design, query optimization, and migrations
• Working experience with TypeScript in production environments
• Familiarity with secure API design, authentication (OAuth2, JWT), and data protection
• Strong understanding of engineering best practices around testing, version control, CI/CD, and code maintainability
• A collaborative mindset, strong communication skills, and the ability to work across disciplines
• A passion for mentoring, shipping high-quality code, and working in a fast-paced startup environment
• Experience with early-stage fintech startups or regulated environments
• Familiarity with compliance frameworks (e.g., PCI, SOC 2)
• Familiarity with accessibility standards, including WCAG guidelines
• Experience with observability tools
• Background in setting up engineering documentation and onboarding processes

Why Join Us

• Take a leadership role with real influence on product, architecture, and culture.
