Xanalys, a Harris Computer company, is currently recruiting for a Principal Software Engineer on a permanent, remote-working basis. This role sits in a small, high-trust business unit supporting a cross-functional, cross-product platform portfolio: legacy and greenfield applications, developer tooling, internal dashboards, and company-wide tools.
This is a senior individual contributor role with technical leadership influence (no direct reports), working closely with the Platform Team Lead and Director of R&D.
Top Priorities
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.

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.
