Sr. Integration Engineer

Hybrid position (ideal candidate located in the Denver area)

C#/.NET 8 required — minimum 5 years | ERP integration experience essential | API-first mindset

You're a senior engineer who thrives in the messy middle — where 'just sync it' is never just syncing it. You've worked with ERPs (Infor, Eclipse, Acumatica, or similar) and know they each have opinions about customers, orders, and inventory — and none of them agree.

You understand that enterprise integration isn't about point-to-point connections — it's about building models that abstract complexity, configurable workflows that adapt without code changes, and architectures that scale across dozens of clients without copy-paste nightmares.

This is a startup environment. You'll have significant autonomy and direct impact on a platform serving enterprise clients. Come grow with us!

Continuum is disrupting the $22B+ B2B Reverse Logistics market — the first and only network-deployed platform to solve complex multi-party returns, warranties, and repairs. Our mission:
If a product moves up the supply chain in B2B distribution or manufacturing, we own it.

• Design and implement connectors that map external ERP schemas to our data model
• Build configurable robust integrations to ERPs and other services
• Create robust API integrations with customer and partner systems (REST, SOAP, webhooks, file-based)
• Lead discovery sessions to understand client ERP configurations and map their data to our platform
• Troubleshoot integration issues in collaboration with customer IT teams and internal engineering
• Optimize for reliability: idempotent operations, retry logic, observability

• 5+ years hands-on with C# and .NET (preferably .NET 8+)
• Strong background in RESTful API development and integration patterns
• Experience with at least one major ERP system
• Postgre
  
  SQL or similar relational database experience
• Comfort with JSON, XML, and data transformation
• Strong problem-solving skills for ambiguous integration challenges

• Azure services:
  Functions, Service Bus, Key Vault, Logic Apps
• Experience with iPaaS platforms (Mule Soft, Boomi, Workato) we use similar patterns
• Understanding of state machines and workflow orchestration
• CI/CD pipelines and Dev Ops practices
• Familiarity relational data schemas and tools like Liquibase

• We're looking for builders, not task-takers.
• Ownership over assignment:
  You see a problem, you own it. You don't wait for a ticket to figure out what needs to happen and make it happen.
• Energized by ambiguity:
  Documentation might be sparse. Requirements might be evolving. Given a goal, you'll find the path.
• Bias for action:
  Done is better than perfect. You ship, learn, and iterate rather than over-engineer in isolation.
• Strong opinions loosely held:
  You have a point of view on architecture, but you're open to being wrong and learning from the team.

We welcome you to join our journey to make B2B returns simple, economical, and green.
