Software Engineer at CipherTek Recruitment, London Area, £700 per day

🚨 Senior Playwright SDET | £700/day | Outside IR35 | Front Office Trading | London

I'm working with a leading global investment bank looking to hire an exceptional Playwright SDET to join their Front Office Derivatives Technology team.

This isn't your typical automation role. You'll be embedded within a high-performing engineering team, working directly alongside developers on a strategic front end trading platform. The rate reflects the calibre of engineer they're looking for.

💰 Package

• £700 per day
• Outside IR35
• 12-month rolling contract
• 1 day per week in the London office

What they're looking for

This role is suited to a highly technical SDET who is passionate about automation and enjoys writing production-quality code.

You must have:

• ✅ Strong commercial experience with Playwright
• ✅ Excellent coding skills in JavaScript and TypeScript
• ✅ Experience building and maintaining automation frameworks
• ✅ Previous experience working on trading applications within an investment bank or financial markets environment would be highly advantageous.
• ✅ Strong understanding of modern front-end technologies
• ✅ Experience integrating automated tests into CI/CD pipelines
• ✅ Ability to work closely with developers on a complex front-end application

The opportunity

You'll be responsible for designing and maintaining automation frameworks, improving test coverage and helping deliver one of the bank's strategic trading platforms. You'll work in a collaborative engineering environment where quality is treated as a core part of software development, not an afterthought.

This is a genuinely challenging role for someone who enjoys solving complex technical problems and wants to work on a business-critical trading platform. The successful contractor will be a strong engineer first and foremost, with testing as their specialism.
