Application Developer

Application Engineer

Location: Hybrid / Belfast (flexible)
Salary: Competitive + benefits
Type: Permanent

I'm working with my client, a well-established and forward-thinking technology organisation, to recruit an Application Engineer to join their growing technical team. This is an excellent opportunity for someone who enjoys working close to both software and infrastructure, and who takes real ownership of application performance, stability, and continuous improvement.

The Opportunity

As an Application Engineer, you'll play a key role in ensuring business-critical applications are reliable, scalable, and well-supported across development and production environments. You'll collaborate closely with development, infrastructure, and support teams, acting as the technical bridge that keeps systems running smoothly and users supported.

This role would suit someone who enjoys problem-solving, improving processes, and working across the full application lifecycle rather than being siloed into a single function.

Key Responsibilities

• Supporting, maintaining, and enhancing business-critical applications

• Troubleshooting application issues across development, test, and production environments

• Working closely with developers, infrastructure, and third-party vendors to resolve incidents and implement improvements

• Monitoring application performance, availability, and stability

• Supporting deployments, upgrades, and configuration changes

• Contributing to documentation, knowledge sharing, and best-practice processes

• Participating in incident management and root cause analysis

• Identifying opportunities for automation and optimisation

What My Client Is Looking For

• Experience supporting or engineering applications in a production environment

• Strong understanding of application architecture and how systems interact

• Experience with Windows and/or Linux environments

• Exposure to databases, APIs, or middleware technologies

• A logical, methodical approach to troubleshooting and problem resolution

• Strong communication skills and the ability to work across technical and non-technical teams

• A proactive mindset with a desire to improve how things are done

Nice to Have (But Not Essential)

• Experience with cloud platforms (AWS, Azure, or similar)

• Scripting or automation experience

• Exposure to CI/CD pipelines or DevOps practices

• Experience working in regulated or enterprise environments

What's in It for You

• The chance to join a stable organisation with a strong technical roadmap

• Meaningful work on systems that genuinely matter to the business

• A collaborative, supportive engineering culture

• Hybrid working and flexibility

• Competitive salary and benefits package

• Clear opportunities for learning and progression
