Their responsibilities often include writing code, testing applications, fixing bugs, and collaborating with teams to deliver functional software. Through this internship, they develop practical skills and a deeper understanding of how web systems work end-to-end.

Familiarity with frameworks such as React or Angular, backend systems like Node.js or Django, version control (Git), and basic database management is typically expected. Strong problem-solving skills, eagerness to learn, and effective communication help interns stand out in fast-paced development teams. These skills and qualities are essential for contributing to real-world projects, collaborating effectively, and accelerating professional growth in a technical environment.

You'll likely collaborate closely with designers, product managers, and other developers, gaining exposure to the complete software development lifecycle. This hands-on experience is designed to help you build practical skills and contribute meaningful code to real applications.

Job description

Washington DC, United States | Posted on 10/27/2025

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.
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

Principled Careers is managing recruitment for this role. We take a values-aligned, transparent approach and ensure candidates feel supported every step of the way. Expect a structured and respectful process, including an initial screen, technical or role-aligned assessment, and culture conversation.

We’re looking for candidates who are based in, or willing to relocate by Q3 2026 to Washington DC (For US candidates only), Saudi Arabia or UAE. You must have a valid Right to Work in the US and one of the countries listed, otherwise your candidacy will not be considered.
