Mid-Senior QA Engineer (B2B SaaS | Fully Remote | UK)

Role Overview

Accessible rail travel depends on systems that work reliably in live environments. Our Passenger Assistance platform turns passenger assistance requests into coordinated action inside live rail operations. We’re hiring a QA Engineer to lead manual quality and release confidence across our UK and Global web and mobile platforms.

Strategic Context

Transreport exists to remove structural barriers in rail travel. Our vision is that everyone has access to travel everywhere. We operate across the UK, Japan, and the EU and have supported over 10 million assistance requests for more than 1 million users. We are a Series A company recognised with a King’s Award. Because we operate in live, safety‑critical environments, quality discipline is fundamental, not optional. As the platform grows in complexity across markets, this role ensures that reliability remains uncompromised.

Outcomes & Impact

• Within 6 months, you will:
• Own manual QA for at least one active product stream.
• Embed earlier into refinement and design to strengthen acceptance criteria.
• Improve regression structure and reduce escaped defects.
• Bring clarity and consistency to our TestRail coverage.
• Act as a trusted release partner for Engineering and Product.
• Within 12 months, you will:
• Confidently rotate across UK and Global teams.
• Influence how we balance manual testing and automation coverage.
• Identify recurring quality risks and drive preventative improvements.
• Raise the overall standard of release confidence across web and mobile.

Tasks

• Execute & Manage Testing: Own the manual testing lifecycle for web (Vue.js/Rails) and mobile (Native Swift/Kotlin) applications.
• Shift Left: Participate in design and requirements sessions, clarifying how A/Cs are tested before a single line of code is written.
• Test Case Management: maintain and expand our TestRail repository. You will decide what needs a manual pass and what candidates should be handed off to SDETs for automation.
• Release Confidence: Act as the final gatekeeper for releases, conducting smoke tests and regression passes to ensure high reliability for our public‑facing and B2B users.
• Cross‑Platform QA: Verify consistency across our web dashboard and mobile apps, ensuring data syncs correctly between the Rails backend and the client devices.

The Tech Environment

• Management: TestRail, Jira.
• Web: Vue.js (Frontend), Ruby on Rails (Backend).
• Mobile: Native Swift (iOS) & Native Kotlin (Android) as well as React Native.

Note: While our stack includes RSpec and Vue wrapper, this is a functional QA role. You are not expected to write code, but you should be comfortable navigating a technical environment.

Requirements

• Experience: 3+ years of experience in manual QA for web and mobile applications.
• Process Mindset: You understand that QA is a process, not just a phase. You can demonstrate how you’ve improved QA workflows in previous roles.
• Context Switching: You are comfortable moving between an established legacy project and a fast‑moving greenfield/scaling project.
• Mobile Proficiency: You know the difference between testing on iOS vs. Android and are familiar with mobile constraints (offline mode, location services, etc.).

• Experience in Government, Public Transport, or Logistics sectors.
• Experience testing SaaS platforms with complex user permissions.

Benefits

• Private healthcare after your probation (including children)
• Hybrid working model
• 25 days holiday
• Cycle and Tech Scheme
• Volunteering Leave
• Free flu jab for you and your family

Culture & Operating Principles

We value: Ownership over hierarchy, Clarity over bureaucracy, Impact over job titles. We operate with high autonomy and high accountability. People are expected to raise risks early, communicate clearly, and take responsibility for outcomes. Quality here is not cosmetic. It protects real journeys.
