Integration Engineer / Hybrid / Chciago

A growing technology company is hiring a full-time Integrations Engineer for a remote role with a hybrid requirement in the Chicago or Denver area (two days per week in office). This opportunity focuses on building and scaling enterprise integrations using C# and modern .NET, supporting a SaaS platform used by large B2B organizations.

This role is ideal for a senior engineer who enjoys solving messy, real-world integration problems and designing systems that scale beyond one-off solutions. The team is building a configurable, API-first integration layer that connects with complex ERP environments. Engineers here have real autonomy, direct impact on the product, and the chance to influence architecture in a fast-moving startup environment without heavy bureaucracy.

• Strong experience building and consuming RESTful APIs

• Exposure to iPaaS platforms or similar integration patterns
• Understanding of workflow orchestration or state machine concepts

• Familiarity with CI/CD pipelines and DevOps practices
• Experience managing database schema changes using tools like Liquibase

What You Will Be Doing
