Integration Engineer (Mid-Level & Senior)
Enterprise SaaS Platform | Central Manchester | Hybrid (2 days onsite)
Location
Central Manchester (Hybrid working – 2 days per week onsite)
Salary & Level
* Mid-Level Integration Engineer: £50,000 – £55,000
* Senior Integration Engineer: Up to £70,000 + 10% bonus
Hiring Plan
Two roles available. The hiring manager is open to appointing one Mid-Level and one Senior Integration Engineer as part of a growing integration and platform engineering function.
The Opportunity
Our client is a well-established, enterprise-scale SaaS business undergoing a significant period of platform growth and modernisation. Integrations sit at the heart of their product ecosystem, enabling high-volume data flows between internal platforms, customers, and third-party partners.
This is a genuinely exciting opportunity to join a business where integration engineering is viewed as a strategic capability rather than a support function. The team is expanding to meet increasing demand, improve scalability, and raise engineering standards across a complex, distributed technology estate.
The role offers strong technical challenge, long-term stability, and clear progression, whether you are an experienced Mid-Level engineer ready to step up or a Senior engineer looking to take ownership of enterprise-grade integrations.
What You'll Be Doing
* Designing, developing, and maintaining scalable integration solutions
* Building and supporting APIs and event-driven integrations
* Working closely with Product, Architecture, QA and Platform teams
* Ensuring integrations are secure, performant, and production-ready
* Supporting live integrations operating at enterprise scale
* For Senior hires: mentoring engineers, influencing design decisions, and setting best practice
Technical Skills & Experience
* Strong experience building integrations using modern integration platforms (e.g. MuleSoft or similar)
* Solid understanding of RESTful APIs, messaging, and integration patterns
* Experience with data transformation (JSON, XML, flat files)
* Exposure to cloud platforms (Azure or AWS)
* Understanding of CI/CD pipelines, version control, and modern SDLC practices
* Experience working in Agile engineering teams
Senior-level candidates will bring deeper architectural experience, confidence owning complex integrations end-to-end, and the ability to guide others technically.
Why Join
* Enterprise-scale SaaS platform with real-world complexity
* Clear investment in engineering and integration capability
* Hybrid working with a collaborative Manchester-based team
* Strong salary, bonus (Senior), and long-term progression
* A role where your work directly impacts platform reliability and growth
