As a Senior Software Engineer, you’ll lead by example: mentoring others, driving technical quality, and delivering scalable, secure, user‑centred solutions. You’ll work closely with engineers, product owners, and designers, and play a key role in our agile delivery.

• Write high‑quality, maintainable code with strong testing and automation
• Lead investigations into complex technical issues and ensure system stability
• Champion engineering best practices and continuous improvement
• Shape system and API design using modern architectural principles
• Communicate clearly with cross‑functional teams
• Mentor junior engineers and support knowledge‑sharing
• Contribute to technical discovery (spikes) and document findings
• Support CI/CD, IaC, and cloud environments (GitHub Actions, Terraform, AWS CDK, CloudFormation)
• Monitor and support live services, including incident analysis and preventative fixes
• Ensure solutions meet security, accessibility, performance, and data‑protection standards

What You’ll Bring

You will be able to demonstrate clear expertise across the following areas:

Development & Coding Hands‑on experience with TypeScript (React, AWS CDK), Git, YAML, Terraform, CloudFormation, Bash/Zsh, and modern tooling (VSCode, GitHub, Vite, Rollup, tsx, npm). Strong logging, monitoring, and branching practices.

Testing & Quality Proficiency with unit, integration, and E2E testing (Vitest, Jest, Cypress, Playwright). Skilled in mocking, dependency isolation, refactoring, and peer review. Understanding of accessibility, performance, load, and security testing.

DevOps & Delivery Experience building and maintaining CI/CD pipelines and working with IaC. Strong focus on observability through metrics, logging, and tracing.

Maintenance & Operations Ability to investigate incidents, perform root‑cause analysis, implement preventative fixes, and ensure backward compatibility.
