We have an exciting opportunity for a Technical Support Analyst to join our Technical Solutions team, supporting complex integrations and applications within a fast‑paced, data‑driven environment.

Joining the Technical Solutions team, you will play a key role in investigating, diagnosing, and resolving technical issues across our systems and interfaces. This role is ideal for someone who enjoys working with data, logs and integrations – someone who is naturally curious, technically minded, and enjoys getting to the root cause of complex issues.

You will work closely with developers, internal teams and clients to ensure issues are understood, communicated clearly and resolved effectively.

• Support developers by clarifying and reviewing task requirements, reproducing issues and providing technical context from support investigations.
• Investigate incidents and defects: triage, gather logs and evidence, identify root cause where possible and raise/track tickets through to resolution.
• Test and QA modifications and fixes, including regression checks, validation against requirements and verification in the relevant environments.
• Deploy and configure software and application servers, including environment setup, configuration changes and post‑deployment smoke checks.

• Experience working with common data formats such as XML, JSON, CSV and plain text (TXT).
• Experience administering and troubleshooting IIS (Internet Information Services), including websites, applications and application pools.
• Experience with software deployments, release management and configuration (including environment setup and post‑deployment checks).
• Experience with software testing/QA and working with application and IIS log files to diagnose issues.
• Experience using fault logging/issue tracking tools (e.g., Jira, Azure Dev Ops, or similar).
• Strong working knowledge of Microsoft Windows and server administration fundamentals.
• Confidence using file searching and log analysis tools (built‑in Windows tools and/or third‑party utilities).
• Understanding of relational databases (e.g., Oracle, SQL Server), including writing and running basic SQL queries.
• Understanding of caching and search technologies (e.g., Elasticsearch, Redis) would be an advantage.
• Good understanding of APIs and web services (REST/SOAP) and how integrated systems exchange data.
• Working knowledge of one or more programming languages (e.g., C#, Java, Python, or similar).

We are a hybrid model, with full‑time employees typically required to come into the office three days per week, with more time in office during onboarding.

In addition to a competitive salary, we offer a wide range of benefits including employer‑matched pension, travel insurance, healthcare schemes, life insurance and more.

We pride ourselves on retaining and developing our people, with a uniquely low employee turnover rate of around 5 % and most employees having been with us for over 10 years.

Based in Slough, UK, Atcore employs around 250 people with an unrivalled combination of industry and technical expertise.

Join us in supporting technology that powers millions of travel experiences worldwide.
