Backend engineer - Follow the white rabbit

Société : Metal Gear

Metal Gear is a B2B fintech company that provides infrastructure for cross-border payouts. Using stablecoins, our platform facilitates fast, cost-efficient fund transfers, challenging the conventional remittance model. Our primary clients are remittance companies that deliver cross-border money transfer services to their customers.

We’ve built a culture and a high-caliber engineering team that relies on on-site presence — not just for collaboration, such as brainstorming and pair programming, but also to foster stronger team dynamics and cohesion. We value teamwork, camaraderie, whiteboard sessions, and good laughs. Our engineers work methodically with processes that have evolved with us in our past experiences and have proven very successful.

We are looking for curious, open-minded, and ambitious people to join us and contribute to the overall development of Metal Gear.
