Principal Software Engineer (AI-Assisted Development Focus)

We are looking for a Principal Software Engineer with strong AI-assisted development skills to lead the design, modernization, and delivery of mission-critical platforms across our products.

This role requires a hands-on senior engineer who:

Writes production-grade code across the full stack

Uses AI coding tools (e.g. Claude Code, Cursor, Copilot) to accelerate development

Can rapidly refactor, modernise, and stabilise large existing codebases

Acts as a technical leader, mentor, and problem solver under tight timelines

You will work closely with architects to rebuild and consolidate systems efficiently, without compromising quality or long-term maintainability.

Key Responsibilities

Cursor

GitHub Copilot or equivalent

Apply AI tools to:

Speed up feature development and refactoring

Understand and modernise large or unfamiliar codebases

Generate, review, and improve boilerplate and repetitive code

Assist with test generation, documentation, and code reviews

Design safe, review-driven AI workflows (AI assists, human validates).

Continuously improve team productivity through AI-enabled development practices and tooling.

DevOps, Quality & Delivery

Work with Azure cloud infrastructure, CI/CD pipelines, and DevOps practices.

Ensure code quality, security, performance, and reliability.

Assist in task planning, estimation, scheduling, and technical staffing decisions.

Improve engineering processes, best practices, and development standards.

Mentor and coach Software Engineers through code reviews, design discussions, and hands-on guidance.

Set examples for clean code, documentation, and maintainable system design.

Collaborate closely with product, BI, and AI teams.

Skills & Requirements

Experience

5+ years of professional software development experience, including technical leadership responsibilities.

Proven experience working on large, complex systems and refactoring legacy code.

Core Technical Skills

Expert-level backend development and database architecture.

Strong understanding of RESTful API design.

Hands-on experience with:

HTML5 / CSS3

Experience with MySQL, Azure SQL, or similar relational databases.

Experience with Azure Cloud, DevOps practices, Git, and CI/CD pipelines.

Hands-on experience using Claude Code, Cursor, Copilot, or similar AI coding tools.

Ability to:

Use AI tools productively without over-reliance

Validate, refactor, and productionise AI-generated code

Strong understanding of AI limitations (hallucinations, security, correctness).

Mindset & Soft Skills

Strong analytical and problem-solving skills.

“Get-things-done” attitude with high ownership.

Comfortable working under tight timelines and ambiguity.

Excellent communication skills, especially when explaining complex technical issues.

Strong documentation and code readability discipline.
