Job Description

The Senior Backend/Integration Engineer is responsible for taking ownership and further developing an existing integration solution built on Microsoft Azure. This role requires a hands-on backend engineering expert with solid experience in Azure-based integrations, system design, and production support. The engineer will join an ongoing project to ensure continuity and improvements in a business-critical integration setup.

Role and Responsibilities

Take over and enhance an existing integration solution primarily based on Azure Logic Apps and Azure Functions;
Design and develop integration solutions using Azure Integration Services (Logic Apps, Azure Functions, Service Bus, Event Grid, API Management etc.).
Participate in knowledge transfer sessions with the current engineer to ensure a smooth handover;
Design, build, maintain, and optimize backend integration flows and services to improve reliability, scalability, monitoring, and maintainability;
Collaborate closely with stakeholders to understand business requirements and translate them into effective technical solutions;
Troubleshoot incidents, resolve issues, and support stable day-to-day operations of the integration solution;
Contribute to architectural decisions and recommend best practices for Azure integration services;
Document the solution comprehensively and help establish a sustainable long-term setup.
Collaborate with cross-functional teams to gather requirements and translate them into technical specifications.
Monitor and troubleshoot integration issues, ensuring high availability and reliability.
Optimize integration processes for performance and scalability.
Document integration solutions and provide training to end-users and team members.
Stay updated with the latest Azure technologies and best practices.

This profile typically represents someone who:

Brings transferable knowledge from traditional/legacy iPaaS or ETL tools (MuleSoft flows → Logic Apps mappings, DataWeave transformations → Functions/Liquid, etc.);
Understands migration paths (e.g., MuleSoft → Azure Logic Apps + API Management + Functions);
Is comfortable building hybrid, event-driven, and API-led integrations in a Microsoft-centric/cloud-native environment.

The ideal candidate is a senior-level consultant who can quickly join the project, absorb the existing context, and create continuity in an integration setup currently dependent on a departing engineer. The candidate is practical, hands-on, proactive, and confident working in Azure-heavy environments with real ownership from day one. Strong communication skills and the ability to work directly with client stakeholders are essential.

Requirements

Strong commercial experience with C# / .NET;
Solid hands-on experience with Microsoft Azure;
Proven experience with Azure Functions and Azure Logic Apps;
Experience building and maintaining system integrations, APIs, and backend services;
Good understanding of event-driven and serverless architectures;
Experience with REST APIs, asynchronous processing, and integration patterns;
Ability to work independently in an existing environment with limited ramp-up time;
Strong communication skills and ability to work directly with client stakeholders;
Comfortable taking ownership of a business-critical solution.
Most likely have prior experience with other major integration platforms, such as MuleSoft (MuleSoft/Anypoint), Informatica, Dell Boomi, Workato, or AWS Glue;
But in recent years have increasingly shifted toward (and gained deeper hands-on expertise in) the Azure integration stack.

Additional Skills (Nice to Have)

Experience with other Azure integration services and tooling;
3–5+ years in one or more of the "legacy" platforms (MuleSoft being especially common in transitions to Azure).
Experience with CI/CD pipelines and deployment automation in Azure;
Experience with monitoring, logging, and performance optimization in cloud environments;
Experience with enterprise integration landscapes or business-critical workflows;
Previous experience in energy, utility, or IoT-related domains.
