About the Job
We are looking for a Senior Software Engineer to drive backend development for mission-critical services, data workflows, and third-party integrations. You will collaborate directly with non-technical stakeholders and the tech team to deliver highly available APIs, custom logic for data transformations, and seamless integrations with key systems like CRMs, WFM, and more that will be the foundation for further product development. You will drive both what needs to be built and how to build it, turning shared ideas into working solutions, with full ownership from idea to deployment.
Responsibilities
- Backend Architecture: You’ll design and implement scalable APIs and services using languages like Python (Flask, FastAPI, DAF), TypeScript (Node.js), or C#.
- Integration Development: You’ll connect and synchronize external systems (CRM, WFM, Wilken) with our internal data and business logic.
- Workflow & Business Rules: You’ll partner with data engineers and platform engineers to develop or integrate rule engines and automation scripts that support device or data-driven operations (e.g., self-healing, auto-escalation).
- Code Quality & Testing: You’ll maintain best practices in unit testing, code review, and continuous integration.
- Performance & Reliability: You’ll monitor and optimize service performance and troubleshoot complex issues across multiple environments.
- Mentorship & Knowledge Sharing: You’ll coach junior developers, foster a culture of clean code and innovation, and lead by example in technical discussions.
