Senior Backend Developer

We’re looking for a reliable Back-end Developer to build and enhance modern, high‑quality backend services using C#, ASP.NET Core with solid experience in ORMs such as Entity Framework Core or Dapper. In this role, you’ll design and implement RESTful APIs, improve data workflows, and ensure strong system performance across our platform. You’ll work closely with cross‑functional partners to deliver clean, maintainable backend logic powered by efficient SQL and robust data access patterns. Experience with search technologies like Elasticsearch is a plus but not required. If you enjoy building clear, scalable backend systems and contributing to steady, high‑quality technical improvement, we’d love to meet you.

What You’ll Do

• Build New Features: Collaborate with Product Managers, Frontend Developers, and fellow Backend Engineers to design and implement new features that enhance functionality, performance, and user experience across our core applications.
• Modernize Our Architecture: Help lead the transformation of our existing monolithic application into a modern, scalable, service-oriented architecture. You’ll have the opportunity to influence key architectural decisions and implement services that are robust, secure, and maintainable.
• Embrace Quality & Scale: Contribute to a codebase that’s clean, well-documented, and covered by tests. You’ll write scalable code with a focus on performance, fault-tolerance, and long-term maintainability.
• Solve Meaningful Problems: Work on real-world challenges in safety, compliance, and operations that have a measurable impact on our customers’ businesses and the well-being of their employees.
• Thrive in a Supportive Culture: Be part of a small, collaborative engineering team where your ideas are heard, your contributions matter, and your growth is supported.
