Thndr is a fintech platform democratizing investment access across the MENA region. The Money Movements Squad owns the critical systems that move money in and out of the platform—deposits, withdrawals, settlement, and reconciliation—processing over 1 billion EGP daily across hundreds of thousands of transactions. Approximately 40% of all Egyptian Exchange transactions flow through Thndr, making this one of the most sensitive and consequential systems in the company.
In this role, you will design, build, and operate backend services that handle money movements across Egypt and the UAE, with Saudi Arabia coming next. You'll own end-to-end correctness and reliability, ensuring that every transaction lands in the right place, in the right amount, every time. You'll build and maintain integrations with banks, payment gateways, payment providers, and asset managers, handling real-world complexities like timeouts, partial failures, retries, and provider outages. You'll raise the bar on quality through strong observability, sensible on-call practices, thorough testing, and systems designed to fail safely. You'll partner closely with finance and operations teams to bring the same connectivity and rigor to new markets.
This is a role where uptime and correctness are not nice-to-haves—they are the entire job. A delayed settlement, a double credit, or a balance that doesn't reconcile is never just a bug; it's real money belonging to real people. You'll work alongside some of the company's strongest engineers on unusually hard and unusually consequential problems.
The Money Movements team operates on a custom in-house ledger built on TigerBeetle, a bleeding-edge financial database designed for correctness and throughput in financial systems.
REQUIREMENTS:
- Strong track record of designing, shipping, and operating reliable backend systems in production used by large numbers of people
- Real depth in distributed systems and clear understanding of what it takes to keep them correct under load and under failure
- Comfort owning systems end to end, from design through production and on-call; you care about how systems behave at 3am
- Familiarity with the stack or confidence to get there quickly: Python, C#, .NET Core, PostgreSQL, SQL Server, RabbitMQ, and Redis
- High bar for correctness and operational discipline; you understand what it means to run a system where mistakes have real consequences
- Clear, candid communicator who can hold their own with other engineers and work closely with finance and operations teams
- Strong debugging skills; when a balance is off by 50 cents across a million transactions, you can find the real cause, not just a quick fix
