Conduct architecture reviews, code reviews, and technical design sessions.
Mentor and support software engineers, senior developers, and technical leads.
Drive continuous improvement initiatives across development processes and tooling.
Champion DevOps, CI/CD, cloud-native development, and automation practices.
Identify and mitigate technical risks while ensuring high-quality delivery outcomes.
Support recruitment, technical assessments, and capability development within engineering teams.
Stay up to date with emerging technologies and industry trends, recommending improvements where appropriate.

- Python
- Go
Experience designing and delivering large-scale distributed systems and microservices architectures.
Strong understanding of cloud platforms such as:
- AWS
- Azure
- Google Cloud Platform (GCP)
Experience implementing CI/CD pipelines and DevOps practices.
Strong knowledge of containerisation and orchestration technologies such as Docker and Kubernetes.
Experience with API design, integration patterns, and event-driven architectures.
Excellent understanding of software engineering principles, design patterns, and coding standards.
Experience working within Agile delivery environments.
Strong stakeholder management and communication skills.
Proven experience mentoring and leading engineering teams.

Desirable Skills

Experience working within public sector or regulated environments.
Knowledge of security, accessibility, and compliance requirements.
Experience with Infrastructure as Code (Terraform, CloudFormation, Bicep, etc.).
Experience with data platforms, analytics, or AI-enabled solutions.
Experience contributing to enterprise architecture and technology strategy.
Relevant cloud, architecture, or engineering certifications.

What We Offer
