Integration Engineer

You're an integration engineer by instinct, not just by job title. You've spent your career making other people's systems talk to yours — the APIs, the SDKs, the protocols no one documents properly, the on-prem environments that don't want to meet the cloud. You'll design and ship the integrations that connect the platform to the third-party systems enterprise customers already run. System to system, on-prem to cloud, cloud to cloud, and the gnarly hybrid in between. You'll own the full lifecycle: scoping, build, UAT, deployment, documentation, training, and the escalations no one else can crack. Stack: .NET / C#. Networking background preferred. 3+ years hands-on .NET development with real third-party API and SDK integration experience required. Strong IP networking fundamentals — firewalls, load balancing, on-prem and cloud environments. Suitable for engineers who like the problems no one else wants, who get bored in pure product-dev roles, or who've been doing integration work under a Software Engineer title for years and want the scope and recognition that comes with owning it properly. Up to £55k. Fully remote within the UK. No office days. No CV required to start the chat. Message Kieran on LinkedIn to fast track. If you use AI to write slop, I won't reply.
