Software Engineer ( Integrations (C#/.NET))

Join a tight-knit development team building integration capabilities across our Process Manufacturing platform. You will design and implement connections between CAIs products and third-party systemsERPs, lab systems, IoT platforms, and customer data sources—that allow manufacturers to operate with a unified data picture. You will collaborate in an apprenticeship-style environment with senior developers, gaining deep product knowledge while owning meaningful integration work from day one. We work with .NET 8+ across a variety of applications, using Visual Studio 2022 and Git, and expect you to move confidently across our codebase. Over your first year you’ll absorb our architecture, contribute to core initiatives, and eventually mentor newer teammates. All you need is strong .NET experience, a systems-integration mindset, and overlap with U.S. Pacific time for smooth collaboration.

The Software Engineer - Integrations responsibilities include but are not limited to:

• Collaborate with senior developers on integration initiatives across CAI’s process manufacturing product suite
• Design, implement, and refactor C#/.NET 8+ code for REST APIs, event-driven connectors, and reusable integration frameworks
• Participate in sprint planning to scope and estimate integration tasks
• Stay organized with work item management and proactively communicate progress and blockers to teammates
• Submit pull requests for your own features and review peers’ PRs, ensuring code quality and integration contract consistency
• Become a product expert by understanding the existing codebase, the product data structures, and the systems we connect to
• Triage and resolve customer-reported integration failures (no on-call rotation)
• Contribute ideas to existing designs and suggest improvements as you become familiar with the product

What You’ll Do

• Design, build, and maintain REST APIs and event-driven integrations between CAI products and external systems (ERPs, LIMS, WMS, IoT, etc.).
• Build and extend reusable integration frameworks that can be adopted across product lines.
• Write integration and contract tests to validate data flows between systems.
• Document integration patterns, authentication flows, and data contracts for internal and customer use.
• Participate in sprint planning and communicate integration design tradeoffs clearly to teammates and stakeholders.
• Leverage AI-assisted development tools—including Claude Code—to accelerate coding, code review, and documentation tasks as part of our standard development workflow.

What We’re Looking For

• 4+ years of professional C#/.NET development demonstrating rapid growth and initiative
• Expert fluency in modern .NET (5+) and Visual Studio 2022; strong understanding of OOP design and API design patterns
• Experience building REST APIs, webhooks, or message-queue integrations in C#/.NET
• Familiarity with integration patterns: pub/sub, ETL, API gateways, OAuth, and API versioning
• Proficiency with JSON, XML, and common data exchange formats (EDI, flat-file) • Strong logical and analytical thinking; comfortable mapping data contracts across systems
• Availability for at least 4 hours daily overlap in U.S. Pacific Time
• • Reliable internet connection to participate in working sessions with screen share

Nice to have:

• Experience with middleware platforms (MuleSoft, Azure Integration Services, Boomi, or similar)
• Exposure to manufacturing data contexts (ERP, MES, SCADA)
• Familiarity with async messaging (Azure Service Bus, RabbitMQ, Kafka)
• Familiarity with Claude Code or similar AI-assisted development tools.

Why Join Us
You’ll work at the intersection of software and manufacturing operations—building the connections that make our customers’ data visible and actionable. This is a growth role with clear paths into integration architecture, product engineering, or technical leadership. You’ll gain deep domain knowledge in process manufacturing while contributing to a product used by 5,000+ customers worldwide.
