About the role
structured by ORIBackBackFounding EngineerFounding EngineerProduct EngineeringPresidio, San FranciscoPresidio, San FranciscoProduct EngineeringPresidio, San FranciscoAs our Founding Engineer, you will define, build, and maintain the technical foundation of our platform. You will join us in-person in a fast-paced, high-ownership…
What you will do
- Full Stack & End-to-End – Design, implement, and operate complete services and user-facing features, from requirements gathering through production support
- System Design & Architecture – Develop highly available, event-driven systems for ledgering, compliance, and risk that scale with transaction volume while maintaining zero downtime
- Implementation Engineering – Embed with customers, collect feedback, and iterate rapidly to ensure our roadmap aligns with user needs
- Technical Decision-Making – Balance speed and long-term scalability, selecting appropriate technologies (Next.js/TypeScript, C#, Go, Python, modern cloud infrastructure) for each problem domain
What they are looking for
- 2–5+ years of professional software engineering, including the delivery of 0-to-1 products and scaling them in production
- Proficiency in at least two of: Next.js/TypeScript, C#, Go, Python
- Hands-on expertise with asynchronous and event-driven architectures
- Full-stack ownership spanning modern front-end frameworks, back-end services, and cloud infrastructure
- Excellent written and verbal communication; ability to influence internal and external cross-functional stakeholders
- Proven expertise with AI-assisted development tools—especially Cursor or windsurf, to accelerate code generation, refactoring, and automated test creation
Nice to have
- Practical experience deploying lightweight machine-learning models for real-time anomaly detection, automated compliance reporting, or incident triage in production systems
- Experience designing and contributing to fintech, payments, or ledgering systems (e.g., double-entry ledgers, payments, clearing, or settlement)
- Experience integrating banking, payments, or compliance providers, or a demonstrated ability to onboard unfamiliar financial APIs quickly
- Prior leadership or mentorship in a high-growth engineering team
