Senior Software Development Engineer in Test (SDET)

About BR-DGE 

BR-DGE is an award-winning FinTech founded in Edinburgh, powered by a high-performing, remote-first team across the UK and beyond. Our platform gives e-commerce and technology businesses the freedom and flexibility to redefine how they handle payments. 

Since 2018, we’ve been pioneers in payment orchestration, enabling enterprise brands to optimise their infrastructure and create frictionless digital experiences. From travel giants to household retail names, our global customer base is growing fast, supported by world-class partners like Visa and Worldpay. 

The journey so far has been incredible, but we’re just getting started. We are looking for exceptional talent to join us as we level up our engineering maturity.

About this role 

At BR-DGE, we champion an inclusive and collaborative approach. Our Senior Software Development Engineer in Test (SDET) role exists to strengthen engineering-led quality across the organisation. You will enable our teams to ship high-quality software frequently and with total confidence. 

As a Senior SDET, you are an engineer first. You will operate both centrally (owning our standards and frameworks) and as an embedded partner within development teams. You’ll be a champion for testability, observability, and the systemic improvements that allow us to scale safely. 

What you’ll be doing 

• Automation and Framework Engineering: Design, maintain and evolve automation frameworks across the full stack: Component, Integration, Contract (Pact), E2E, and Performance/Load testing. 

• Embedded Partnership: Partner with development teams during refinement, build and release phases to embed quality criteria into sprint planning and definitions of done. Coach on automation, testability, observability and quality first design. 

• CI/CD Optimisation: Ensure our pipelines are fast, reliable, and CI-native, implementing meaningful quality gates and reducing feedback loops. 

• Engineering for Testability: Suggest architectural improvements to enhance testability and advocate for patterns that support robust contract testing. 

• Observability and Reliability: Strengthen our monitoring and alerting standards, participating in incident post-mortems to turn ‘learnings’ into automated safeguards. 

• Metrics-Driven Growth: Use DORA metrics to provide visibility into quality trends and drive continuous improvement. 
• Leadership and Engineering Maturity: Proactively drive forward the organisation-wide quality strategy, designing the high-level architecture of our testing ecosystem, and mentoring junior engineers. Act as a thought leader to coach development teams, championing 'quality-first' design to improve delivery speed and move the needle on engineering maturity.

What we’re looking for 

This role is for an engineer who wants to shape our architecture and culture. We are looking for someone who balances deep technicality with the ability to influence how we work.
Essential Experience 

• Recent professional experience as a Software Development Engineer in Test (SDET) or equivalent role. 

• Strong software engineering fundamentals with professional proficiency in Java, TypeScript, or similar modern languages. 

• A proven track record of designing and maintaining multi-layered automation frameworks from Component and Integration to Contract (Pact), E2E, and Performance/Load testing. 

• Hands-on experience building CI/CD pipelines, integrating automated quality gates, and optimising for fast, parallelised feedback loops. 

• The ability to independently debug application issues, influence product design to maximise testability, and proactively coach engineers on best practices for unit and component testing. 

• The ability to suggest architectural system design improvements that enhance testability, observability, and logging across cloud-native environments. 

• Passionate about monitoring and alerting standards, with experience turning incident learnings into systemic, automated safeguards. 

• Communication skills to be able to coach development teams, drive ‘quality-first’ design, and move the needle on engineering maturity. 

• Display thought leadership in the quality space, focusing on improving delivery speed whilst maintaining quality. 

Nice to Have 

• Experience implementing and tracking DORA metrics (Deployment Frequency, Lead Time for Changes, Change Failure Rate and Time to Restore Service). 

• Familiarity with feature flagging and progressive delivery strategies. 

• Experience in fintech, payments or other highly regulated environments where transactional integrity and reliability are critical. 

Why this role exists 

Our business is growing rapidly. We recognise that to achieve fast delivery and systemic quality, we need engineers who shape how quality is built into the system. If you are passionate about delivering engineering excellence, we want to talk to you. 

What we offer 

We provide a supportive, high-growth environment where your impact is visible every day. 

• Financial: Competitive salary and life insurance. 

• Time Off: 33 days holiday (including public holidays) plus Birthday Leave. 

• Flexibility: Remote-first working culture that respects your other priorities. 

• Health: Family private healthcare and an Employee Assistance Programme. 

• Growth: A culture that champions career progression and direct investment in your learning and development. 

• Community: Regular team events and socials to keep our remote team connected.
