Senior Integrations Engineer

Senior Integrations Engineer

Greater Cleveland, OH — hybrid, 2–3 days on-site

The short version

We are an established B2B software company. We grew by building and by integrating products we purchased, so we now run a suite of products rather than one — and a growing roster of outside vendors wants to plug into them.

Somebody has to build the front door. That is this job.

The distinction that matters

There are two kinds of integration work here, and we are only hiring for one of them.

The first is building a specific integration for a specific business need — wiring product A to product B for a particular workflow. We already have a team that does that.

The second is building the platform everyone else integrates (including Vendors) through. You design and publish the APIs. You decide how an outside company reaches our core systems securely, quickly, and without any hand holding them. Once a vendor is connected, they run on their own and nobody on your team touches it again.

That second one is the job. If you have built the thing partners integrate into, rather than integrations between things, keep reading.

What you would own

- The public API surface: designing it, publishing it, versioning it, and holding it to real standards for security, performance and documentation

- Partner enablement — the connectors, tooling and documentation that let an outside company integrate with very low effort and no help from us

- Integration patterns across the platform: API-based integration, event-driven messaging, data synchronization, workflow orchestration

- Building in C#  on Azure, with an embedded iPaaS (we run Prismatic) for connector development

- CI/CD, automated testing and deployment automation for integration work

- Monitoring and observability, so integration health is something you can see rather than something you guess at

- The hard failures — the ones that cross system boundaries and nobody else can reproduce

Honestly, what this role is not

- It is not a pure architecture seat. The first three to six months are heavy on architecture while you set the direction, and you will have other architects to lean on. After that it settles into a hands-on senior engineering role owning what you built.

- It is not a low-code configuration job. We are not using someone else's connectors to integrate our software. We are building the connectors.

- It is not a maintenance role. The person who built this platform has moved on, which means it is open for someone to shape.

What we are looking for

- 7+ years building software, with a real share of that on APIs and integrations

- Strong, current C#  with REST API development — this stays hands-on

- Hands-on Azure: API Management, Service Bus, Event Grid, Functions. We are a Microsoft shop and we mean it

- Experience building connectors or an integration platform — Prismatic, Mule Soft, Workato, a homegrown connector framework, or comparable

- A track record designing APIs that people outside your own company consumed

- Working knowledge of event-driven and API-first design across distributed systems

- CI/CD and Dev Ops practice applied to integration work

- Someone who communicates well across product, engineering and support, and can turn architectural direction into something built

What makes you stand out

- You have built or run an integration marketplace, or a developer portal partners self-serve from

- EDI or other standardized data exchange with outside partners

- Payments experience — ACH, card rails, reconciliation

- AWS or GCP alongside Azure

- You have absorbed an acquired company's product into an existing platform

- You have put AI into an engineering workflow and governed it properly, not just used it

Why this one is worth a look

The direction is already funded and decided. Tooling already chosen, a clear mandate. You are not fighting for budget or relitigating strategy.

Real ownership. You are not inheriting somebody's platform and keeping it warm. You are deciding how partners connect to a product tens of thousands of professionals already run on.

Stability with momentum. A forty-year-old, profitable market leader that is investing seriously in engineering right now.
