Technical Support Engineer

Tech Support Engineer

Do you enjoy solving complex technical issues and getting to the root cause of problems? Are you comfortable working with SQL, REST APIs and enterprise software while interacting directly with customers? Join Aon and help support a growing technology platform used by enterprise clients!

This is a hybrid role based in Poland, offering flexibility to work both virtually and from an Aon office in line with our local smart working policy.

Aon is in the business of better decisions

At Aon, we shape decisions for the better to protect and enrich the lives of people around the world.

As an organization, we are united through trust as one inclusive team, and we are passionate about helping our colleagues and clients succeed.

What the day will look like

In the role of a Customer Support Engineer, you will investigate and resolve technical issues reported by business clients and internal teams. You will engage with different areas of the platform, fix integration failures, authentication errors, data delivery issues and performance anomalies.

Your day-to-day responsibilities will include:

• Investigating technical issues using SQL queries, REST API debugging, application logs and Azure monitoring tools, reproducing problems and identifying root causes.
• Handling support tickets from initial investigation through resolution, providing customers with clear updates, next steps and resolution information.
• Working directly with enterprise customers and adapting your communication for both business users and technical IT teams.
• Collaborating with the Technical Support Lead, ATS Integration Consultant, QA and engineering teams when issues require deeper investigation or indicate potential platform defects.
• Documenting solutions and sharing knowledge with the team, while using AI tools to support technical investigations and everyday customer communication.

How this opportunity is different

You’ll analyze and resolve technical issues, engage personally with customers, and collaborate with engineering and platform teams when deeper technical expertise is needed.

You will have the opportunity to investigate issues across multiple components of an evolving technology platform rather than simply passing complex problems to another team. You will work alongside specialists across technical support, integrations, quality assurance, and development, building knowledge across the wider platform.

AI-supported ways of working are also a meaningful part of the role. You will be encouraged to use AI tools effectively and responsibly as part of your day-to-day technical support activities.

Knowledge and experience that will lead to success

• 2+ years of experience in technical support, platform operations or application support within a SaaS or enterprise software environment.
• Strong hands-on SQL proficiency and demonstrated experience in troubleshooting REST API integrations, including interpreting error codes and analysing request/response payloads.
• Strong analytical and troubleshooting skills, showing proficiency in investigating complex problems methodically and uncovering underlying causes.
• Excellent written communication skills and the ability to explain technical findings clearly to both non-technical personnel and technical collaborators.
• Working knowledge of C#/.NET applications at a diagnostic level, combined with capacity to balance multiple support cases independently and work effectively in an international team.

Experience with Azure, Application Insights, Datadog, Kubernetes, enterprise ATS integrations such as Workday, SAP SuccessFactors or Taleo, and support tools such as Zendesk or Jira Service Management would be an advantage.
