Senior Software Engineer in Test

Enterprise SaaS Platform | Manchester | Hybrid (2 days onsite)

Salary: up to £70,000 + 10% bonus

The Opportunity

This is a chance to join a high-growth, enterprise SaaS organisation building complex, high-throughput platforms used at scale across the UK and Europe. Quality Engineering is treated as a core engineering discipline, not a support function.

As the platform scales, the business is investing in engineers who can engineer quality in from day one — not test at the end.

The Role

As a Senior Software Engineer in Test, you’ll operate as a true engineer within a product-aligned squad. You’ll own automation-first testing across cloud-native, API-driven systems and play a key role in shaping how quality is embedded across the wider platform.

This is a hands-on role with real influence — not a test-lead-by-proxy position.

What You’ll Be Doing

• Designing and delivering robust test strategies aligned to product and platform goals
• Building and evolving automated test frameworks across UI, API, integration, and performance
• Driving a culture of automation-by-default and continuous improvement
• Testing complex, distributed systems and high-volume integrations
• Contributing to CI/CD pipelines and release confidence
• Partnering closely with Software Engineers and Product teams
• Mentoring junior engineers and raising quality standards across squads

What They’re Looking For

Essential

• Strong coding background (C# preferred)
• Automation experience with Playwright, Cypress, or similar
• Solid API testing experience (REST, Postman, SoapUI)
• Experience working in Agile, product-led teams
• Cloud exposure (Azure or AWS)

Nice to Have

• Docker / containerised test environments
• Performance testing (k6 or similar)
• Experience testing complex integrations and platform systems

Why This One’s Different

• Up to £70k base + 10% bonus
• Hybrid working – Manchester, 2 days onsite
• Long-term SaaS product, not short-term projects
• Real ownership, autonomy, and technical influence
• Clear progression for senior engineers who want depth, not people management
