Senior Integration Developer (SaaS)

We're looking for a Senior Integration Developer to design and build the core integration logic that connects our platform with external systems. This role is for someone who enjoys writing complex backend business logic, handling real-world system interactions, and building reliable integration workflows inside a product not just moving data from point A to B.

You'll work on features that allow our platform to communicate with partner systems, client environments, and third-party applications in a reliable, maintainable way.

What you'll do

Design and build integration modules within the application that handle communication with external systems

Develop and maintain business logic for data exchange, synchronization, validation, and reconciliation

Implement workflows that manage request/response handling, retries, failure handling, and state tracking

Translate external system requirements and specifications into clean, maintainable application logic

Ensure integrations are resilient, auditable, and aligned with real-world operational scenarios

Build reusable components and frameworks that standardize how integrations are handled across the platform

Handle edge cases such as partial failures, duplicate messages, out-of-order data, and system timeouts

Participate in design and architecture discussions to evolve the platform's integration capabilities

Mentor junior developers and promote clean coding practices for complex logic-heavy modules

What we're looking for

6+ years of software development experience, with strong experience building integration logic inside product applications

Proven experience designing backend workflows that interact with external systems and handle complex state and error scenarios

Extensive hands-on development experience in .NET (C#) with ASP.NET MVC applications

Strong database expertise in SQL Server, including writing complex queries and ensuring consistency in transactional workflows

Strong understanding of application-layer data validation, transformation, and mapping

Ability to design systems that are reliable, fault-tolerant, and easy to support in production

Comfort working with evolving external requirements and translating them into stable internal logic

Strong debugging skills across multi-step workflows and distributed interactions

Clear communication skills for working with cross-functional teams on integration features and production issues

Nice to have

Experience integrating SaaS platforms with third-party business systems

Exposure to healthcare or other regulated industry environments

Experience working in multi-tenant SaaS architectures

Understanding of logging, monitoring, and audit practices for integration workflows

Experience designing reusable frameworks or libraries within large applications

This role is critical to how our platform interacts with the outside world. You'll be building the integration engine inside the product ensuring external system interactions are reliable, predictable, and production-ready.
