Company Description

Join us as a Senior Configuration Engineer (XML)/Technical Lead! Build XML configs, deploy via Azure pipelines, and support UK clients. Grow your skills in our dynamic team!

We have a great opportunity for a Senior Configuration Engineer (XML)/Technical Lead who is ready to solve complex issues and would like to work closely with the product.

In this role, you will be responsible for implementing technical tasks related to XML files that are used as configuration files for the engine that generates reports and Azure DevOps pipelines. You will work in a team directly with the client, so it is a great opportunity to build strong professional relationships. Are you with us?

CUSTOMER
Our UK client is an environmental and sustainability reporting company with a focus on supporting businesses that comply with or commit to a wide range of global packaging, plastics, tax, EPR, and corporate metric submissions.

PROJECT
We are looking for a proactive and detail-oriented Configuration Tech Lead to join our team on a long-term project in the environmental compliance and packaging data management domain. The system processes large volumes of structured product and packaging data to ensure compliance with regulations across multiple markets. The role is focused on configuration, XML-based tasks, testing, and leading a team of engineers.

You will work closely with the client to analyze business requirements, convert them into structured technical specifications, and oversee their implementation by your team. This is not a traditional software development role — it requires precision work with structured data, test design, quality control, and strong communication with both your team and stakeholders.

Job Description

• Lead a team of Junior engineers by providing technical guidance, assigning task, and offering mentorship
• Review and analyze business requirements provided by the client, and translate them into detailed technical configurations (e.g. a traceability matrix with development acceptance criteria)
• Design, implement, and execute test cases based on business logic using a custom client framework
• Work with XML data structures, ensuring correctness, completeness, and consistency
• Perform code and configuration reviews, ensuring high-quality deliverables from Junior team members
• Maintain clear documentation of configurations, processes, and logic for future reference
• Communicate with the client to clarify requirements, provide updates, and proactively raise issues or suggestions
• Track the progress of assigned tasks and teamwork against planned deadlines and project milestones
• Collaborate with the team to manage and troubleshoot Azure Pipelines, builds, and deployment processes

• Ensure that all configuration and testing activities aligned with internal SDLC and quality standards

   

Qualifications

• At least 5+ years of experience in a technical role (strong Middle or Senior level)
• Experience in team leading, including mentoring, task breakdown, and progress tracking
• Strong knowledge of testing principles: ability to design test cases based on business requirements and implement them using a custom client framework
• Ability to analyze and clarify business requirements, transform them into configuration logic, and create WBS for teammates
• Solid understanding of structured data formats, especially XML
• Familiarity with typical SDLC processes: code reviews, test runs, and version control
• Experience with Microsoft Azure Pipelines, including setup, monitoring, and troubleshooting of builds and deployments

• Upper-Intermediate level of English or higher, with strong verbal communication skills

   

WOULD BE A PLUS

• Ability to independently research domain-specific information (e.g., properties of packaging materials)
• Familiarity with environmental regulations or data reporting systems

• Prior experience of working in configuration-heavy or non-development roles
