You will take ownership of functional and technical topics across the full feature lifecycle, from discovery and specification through technical design, development, testing, documentation, deployment, and maintenance.

As a Senior Software Engineer, you will also help shape the squad’s technical direction, lead initiatives, support strong engineering practices, and contribute to a positive and collaborative team culture.

Key responsibilities

• Design, develop, and maintain reliable backend services and workflows for KYC and customer onboarding.

• Contribute to frontend development with React, representing approximately 30% of the role.

• Own complex technical and functional topics throughout the full feature lifecycle.

• Define and evolve robust architectures, applying principles such as hexagonal architecture and clear domain boundaries.

• Lead technical initiatives from discovery and design through implementation, delivery, and continuous improvement.

• Build maintainable, performant, observable, and well-tested software.

• Collaborate with Product, Design, Engineering, Compliance, Operations, and other stakeholders.

• Use AI-assisted development tools daily, share effective practices, and help promote responsible usage across engineering.

What we’re looking for

• Fluency in written and spoken English, our business language.

• At least 5 years of experience in software development, ideally in a product-focused environment.

• Strong expertise in TypeScript, particularly for backend development with Node.js.

• Experience with AWS, Kubernetes, Terraform, or infrastructure-as-code.

• A proven track record of designing and delivering high-quality, scalable products.

• Strong architectural knowledge, including experience with hexagonal architecture and maintainable system design.

• The ability to lead initiatives and make sound decisions with a high degree of ownership and autonomy.

• A product-oriented mindset, with the ability to contribute to discovery, prioritisation, meetings, and squad rituals.

• A collaborative attitude, strong customer focus, and enthusiasm for building a positive team culture.

Nice to have

• Experience working in financial services, payments, fintech, or another regulated industry.

• Experience integrating with third-party providers through APIs, external services, and webhooks.
