Lead Software Engineer

As a Senior Engineer in the Finance cluster, you will architect and build the technological infrastructure that powers On s global financial operations. You will play a pivotal role in transitioning our finance ecosystem toward a "North Star" architecture - moving away from legacy patterns toward a high-performance, event-driven landscape. By leveraging Kafka for real-time data streaming and NestJS for robust microservices, you will ensure our financial systems - from global tax compliance to automated bank integrations - are scalable, reliable, and future-proof.

Your Story

• TypeScript Mastery: Extensive experience building backend services specifically with NestJS and Node.js.
• Streaming Expertise: Proven experience implementing Apache Kafka in production environments to handle high-throughput data.
• Logical Problem Solver: Proficient in leading technical discovery and breaking down "Big Bang" migrations into manageable, iterative releases.
• Cloud & DevOps Native: Strong track record with Kubernetes, Terraform, and automating deployments through GitHub Actions.
• Domain Curiosity: Technical experience with ERP systems (D365 F&O) and financial processes - such as Landed Cost, tax engines, or CNAB bank integrations - is a plus.
• Collaborative Partner: You communicate effectively with both technical peers and Finance stakeholders to translate business needs into architectural requirements.
