Senior Software Engineer – AI Automation Platform – Belfast/Hybrid
We're partnered with an AI‑Powered Fintech that is moving into the first stage of a large scale expansion over the next six months.
The team is currently focused on developing a platform designed to accelerate AI and generative AI initiatives across the organisation, leading the build and implementation efforts.
Join a high‑growth SaaS team building real AI automation — not chatbots. We are talking end‑to‑end workflow intelligence: document ingestion → accounting → tax → filing — used by tens of thousands of businesses.
You’ll architect and own the API layer that powers product integrations, platform scalability, and smart AI features across multiple mission‑critical systems.
What you’ll do:
* Design and build secure, scalable APIs in C#/.NET and Azure
* Shape API standards, gateway strategy, versioning, and authentication
* Drive event‑driven integrations and seamless third‑party connectivity
* Lead API performance, reliability, and observability improvements
* Mentor engineers and influence architecture across multiple teams
What you bring:
* Deep C#/.NET experience in production systems
* Strong REST API design and OpenAPI/Swagger knowledge
* SQL expertise and cloud experience with Azure services
* Security‑first engineering mindset (sensitive data handling)
* Ownership across the lifecycle – design, build, deploy, and run
