With an experienced leadership team spanning financial services and technology, the company is assembling its founding engineering team. This is an opportunity to join at an early stage, where you'll help define the architecture behind a platform designed to process financial transactions with the reliability and scalability expected of modern brokerages.

What you will do:

Designing and building highly reliable backend services for transaction processing and financial operations.

Developing scalable services that support order processing, account balances, funding workflows, reconciliation, and other mission-critical financial functions.

Building resilient distributed systems capable of handling failures gracefully through robust retry strategies, idempotent processing, event-driven architectures, and strong observability.

Working closely with engineering leadership to define backend architecture, engineering standards, and long-term technical direction.

Integrating with third-party financial institutions, banking partners, identity verification providers, and other external platforms.

Building internal operational tools that improve visibility, troubleshooting, reconciliation, and support workflows.

Contributing to infrastructure supporting AI-powered financial research and data processing initiatives.

Participating in production operations, monitoring, incident response, and continuous platform improvements.

What you will need:

Around 6+ years of experience building production backend systems.

Strong experience designing scalable distributed systems running in production.

Hands-on experience with backend technologies such as Go, Java, Kotlin, Python, C#, Rust, or similar modern languages.

Strong understanding of databases, event-driven architectures, messaging systems, caching, and scalable infrastructure.

Experience designing systems where correctness, consistency, and reliability are essential.

Solid understanding of transactions, concurrency, retries, reconciliation, and failure recovery.

Experience supporting production systems, including monitoring, debugging, and incident management.

Comfortable working in fast-moving startup environments where priorities evolve quickly and engineers take ownership beyond writing code.

Strong English communication skills and the ability to collaborate with distributed international teams.
