Job description

Applications Engineer – Tier 3

Location: Halifax | Working arrangement: Hybrid 2 days a week onsite Bayers Road

Ready to solve complex problems and make application services smarter?

We’re looking for a hands‑on Applications Engineer to join a team responsible for keeping critical business applications running securely, reliably and efficiently.

This is a senior technical support and engineering role where you’ll go beyond fixing immediate issues. You’ll investigate complex problems, get to the root cause, implement lasting solutions and look for smarter ways to manage and improve application services.

You’ll be working across enterprise applications, application servers, middleware, APIs and the infrastructure that supports them, collaborating with teams across infrastructure, networking and security.

With a growing focus on automation, simplification and AI, this is an opportunity to help shape how application services are supported and improved, rather than simply maintaining the status quo.

What you’ll be doing

Own complex technical issues: Act as a Tier 3 escalation point, taking challenging application problems from investigation through to resolution.

Keep applications running: Support and administer business-critical enterprise applications, application servers and middleware across Linux and Windows environments.

Get to the root cause: Use logs, monitoring and performance data to diagnose issues, eliminate recurring problems and implement permanent fixes.

Connect the dots: Troubleshoot APIs, integrations, database connectivity, authentication and secure communications between applications and infrastructure.

Automate the everyday: Use scripting and automation to reduce manual tasks, improve consistency and make operational support more efficient.

Improve reliability and security: Support application deployments, upgrades, patching, monitoring and performance improvements.

Explore AI‑driven improvements: Bring an interest in AI and new ways of working to help simplify operations and make application support more proactive.

Share your expertise: Work closely with other technical teams, contribute to standards and documentation, and help develop the skills of more junior engineers.

What we’re looking for

We’re looking for someone with strong hands‑on application engineering experience who enjoys solving problems, understanding how systems fit together and finding better ways to do things.

You’ll ideally bring:

• Experience supporting business‑critical enterprise applications in a Tier 3 or similarly senior technical support role.
• Strong application administration and troubleshooting skills, including experience with application servers and middleware.
• A good understanding of Linux and/or Windows application hosting environments.
• Experience working with APIs, integrations and secure connectivity, including HTTPS.
• An understanding of database connectivity and application authentication technologies such as LDAP, Kerberos, SAML or OAuth.
• Experience with application monitoring, logging, performance troubleshooting, deployments and patching.
• Scripting or automation experience, alongside a genuine interest in reducing repetitive manual work.
• A proactive approach to problem‑solving, a strong sense of ownership and the ability to work independently on complex technical issues.

Useful experience to have

You don’t need to have worked with every technology listed, but experience with some of the following would be beneficial:

• Scripting and automation: Python, Bash, PowerShell or Ansible.
• Version control and engineering tools: Git and GitHub.
• Application and identity platforms: Mattermost, Keycloak, Apache or NGINX.
• APIs and integrations: REST APIs and application‑to‑application connectivity.
• Monitoring and observability: Grafana, LogicMonitor or Icinga.
• An interest in AI and how it can improve application operations is particularly welcome.

Why consider this opportunity?

• This is a chance to take ownership of meaningful technical challenges, work across a broad application and infrastructure landscape, and have a genuine impact on how services are delivered.
• You’ll be able to use your technical expertise to improve reliability, reduce recurring issues, introduce automation and contribute to the evolution of application services, with AI and continuous improvement firmly in the picture.
• If you’re an engineer who likes getting hands‑on, solving the problems others struggle with and making systems work better for everyone, we’d love to hear from you.
