Job Description
Full Stack Engineer - Fintech (Remote / MENA Focus)
Principled Search is partnering with a venture-backed fintech startup that has raised over $3M to rebuild cross-border banking and payments infrastructure across MENA. With a small but exceptional founding team, the company is tackling one of the toughest problems in global finance: enabling seamless, compliant, and low-cost money movement across borders.
We are now looking for two Full Stack Engineers to join at the ground floor - defining, building, and scaling the technical foundation of the platform.
The Role
As a Full Stack Engineer, you'll operate as a true generalist designing, implementing, and operating complete end-to-end systems that power modern cross-border payments. You'll have significant influence over product direction, technical architecture, and engineering culture as the company scales.
What You'll Do
  • Full Stack Ownership: Design, build, and operate services and user-facing features from concept to production, ensuring reliability and scalability.
  • System Design & Architecture: Architect distributed systems capable of scaling transaction volume globally with zero downtime.
  • Implementation & Customer Feedback: Work closely with customers and partners to iterate rapidly, aligning the product roadmap with real user needs.
  • Technical Decision-Making: Balance execution speed with long-term scalability, choosing the right technologies for each challenge.
What You've Done
  • 3-6+ years of professional software engineering experience, including taking 0→1 products into production and scaling them successfully.
  • Background in a leading fintech or crypto company
  • Expertise in React / React Native, TypeScript, Node, Supabase, and AWS.
  • Strong full-stack capability spanning frontend frameworks, backend services, and cloud infrastructure.
  • Proven use of AI-assisted development tools (e.g. Claude-CLI, Cursor, or similar AI-first workflows).
  • High personal drive, ownership mindset, and readiness for an early-stage startup pace.
Bonus Points
  • Experience integrating banking, payments, or compliance providers, or fluency in onboarding new financial APIs.
  • Knowledge of ledgering systems, payments infrastructure, or settlement flows.
  • Understanding of stablecoins, blockchain-based payments, or crypto rails.
  • Familiarity with global FX markets and cross-border flows.
  • Arabic language skills.
Why This Opportunity
  • Competitive early-stage compensation + equity
  • Remote-first with flexibility across time zones
  • Direct impact on shaping one of the most ambitious fintech infrastructures in the MENA region
  • Build alongside an elite founding team solving a high-impact, high-barrier global problem

Application Process
