Freelance Software Engineer - Backend TypeScript

Swan is Europe’s embedded banking specialist. We empower software companies to embed banking features like accounts, cards, and payments directly into their products, under their own brand.Swan processes over €1.5 billion in monthly transactions for more than 150 companies—like Pennylane, Indy, Agicap, Libeo, and Lucca. Founded in 2019, the company has received growth capital from leading investors such as Lakestar, Accel, Creandum, Bpifrance and Eight Roads. Swan is a principal member of Mastercard and a licensed financial institution, regulated by the French banking authority (ACPR).

Many software companies already serve small businesses incredibly well: helping them send invoices, run payroll, manage inventory, and more. They’re on a mission to become the central hub for managing every aspect of business life.

But when it comes to financial workflows, there’s still a gap. Too many critical tasks like managing cash flow, tracking payments, or reconciling accounts happen outside the software, across spreadsheets, email threads, banking portals.

It’s a missed opportunity. Business software shouldn’t just record financial activity — it should run it.

Swan’s core values guide our actions daily. Individually, they may seem obvious, but together, they form a unique culture.

Simplicity: Leonardo Da Vinci said: “simplicity is the ultimate sophistication.” If something's convoluted or confusing, we work extra hard to break it down. - Making complex things simple is what we do.

Long Term: We always play the long game, whether it's to support our partners in their growth journey, or make tangible commitments to climate action.

Excellence: We are a team of experts who consistently go all out to create pixel-perfect banking services and exceed our partners' expectations— whatever it takes.

Be Human: We believe in the power of kindness and the importance of acting with integrity. But embracing our humanity extends beyond interpersonal interactions, it means caring about greater issues that affect our planet.
