Integration Engineer (Mid-Level & Senior)

Enterprise SaaS Platform | Central Manchester | Hybrid (2 days onsite)

Central Manchester (Hybrid working – 2 days per week onsite)

• Mid-Level Integration Engineer : £50,000 – £55,000
• Senior Integration Engineer :
  Up to £70,000 + 10% bonus

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.

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.

• 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

• Strong experience building integrations using modern integration platforms (e.g. Mule Soft 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.

• 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
