Principal Software Engineer

• AI workflow usage and implementation are a key part of this role: use AI tooling heavily and daily, and design/ship agentic workflows that improve team delivery.

• Maintain a quality and testing-first engineering approach: automated unit, integration, end-to-end, and acceptance testing are core to delivery.

• Own SRE and DevOps outcomes as a top priority: reliability, observability, operability, CI/CD health, and continuous improvement are part of day-to-day ownership.

Scope of the Role

• Work profile: approximately 80% hands-on engineering, 20% planning, triage, review, retros, and technical leadership activities.

• Ownership: own modules and features end-to-end (design, build, test, release, production support), not entire enterprise products.

• Landscape influence: understand the broader enterprise landscape, form strong technical opinions, and drive change across products.

• Stewardship: adopt and stabilise orphaned modules, then bring them up to current standards.

Core Responsibilities

• Use AI tooling heavily and daily: Copilot, Claude, and agentic workflows, including creation of skills, agents, rules, plugins, instructions, and prompt patterns.

• Champion and train others (technical and non-technical) in collaborative AI tooling and workflow agentification.

• Ensure outward communication is human-curated, concise, and thoughtful; never publish unedited AI output.

• Maintain a quality and testing-first approach with automated unit, integration, end-to-end, and acceptance testing.

• Deliver and improve complex enterprise systems spanning hybrid monoliths and standalone modules.

• Build, scale, and optimise solutions across .NET, SQL Server, Azure, Terraform, Docker, PowerShell, bash, XML, and XSL.

• Own CI and CD through Azure DevOps pipelines, including quality gates and deployment automation.

• Run structured release management using established CD systems, disciplined tagging/versioning, and Jira release management.

• Integrate and support third-party components, packages, and integrations.

• Follow established patterns and practices, and introduce better ones where justified.

Required Experience and Attributes

• Significant hands-on engineering experience with deep .NET and SQL Server capability.

• Comprehensive scripting capability in PowerShell and bash for build, deployment, operations, and troubleshooting.

• Proven CI/CD and release management capability (including tagging/versioning and Jira release practices).

• Strong ownership mindset, proactive communication, and high personal organisation.

• Demonstrated ability to mentor others and raise technical standards through influence.

• Confidence working directly with customer technical teams in regulated settings.

• Ability and willingness to obtain Security Clearance

Nice to Have

• Experience scaling and optimising legacy systems.
