Shape product quality end-to-end by owning testing across web and APIs, embedding in Agile teams, and building scalable QA frameworks.

Changing the world of pet food for good

We’re Tails.com, a dog food subscription company with a big difference. We create truly tailored food for each and every dog we serve. We start by asking people a few simple questions about their dog. Then we use that information to create their dog’s unique Tails.com recipe – so their dog gets exactly the nutrition they need, in the taste they love, delivered to their door every month. It’s clever stuff.

We’ve got bold plans. Having created an entirely new category in pet food, we’re now scaling fast – backed by Purina, one of the world’s largest pet food companies. You’ll join a bunch of smart people working towards the same goals – and a bunch of smart-ish dogs, all working on their own thing.

Together, we’ll change the world of pet food for good.

Build our brand

We’re building an international brand, fast. We set ambitious goals. We challenge and support each other in equal measure. At the pace we’re moving, we prefer to test ideas and learn quickly rather than spend months building a business case. That means we celebrate when things go right, and we learn when things go wrong.

Sound like a team you want to join? Here’s how you’ll make a difference:

We’re looking for a Mid-Level Quality Assurance Engineer to own day-to-day manual and automated testing of new and amended features across web applications, APIs, and supporting data stores. You’ll work embedded in an Agile squad, partnering closely with engineers, product and design to ensure requirements are clear, risks are understood early, and quality is built in from the start.

You’ll create high-quality test cases through in-depth technical analysis of functional and non-functional requirements (e.g., reliability, security, performance, accessibility). You’ll specify what’s needed for effective testing (environments, data, tooling), design reusable test scripts and regression packs, and contribute to improving best practices—particularly helping evolve our approach and framework for API testing.

The role

What you’ll do

Create test cases from functional and non-functional specifications, defining test requirements and coverage by risk.
Specify test environment, test data, resources, and tooling needs to execute testing effectively.
Design and maintain reusable test scripts, procedures, and regression packs with expected results.
Execute and document complex test scripts using agreed methods and standards; monitor progress and report anomalies, risks, and issues.
Maintain traceability from requirements to test cases and provide clear reporting on system quality and test metrics.
Log, triage, and manage defects with strong evidence and analysis; maintain a defect register and contribute to root-cause prevention.
Test across key areas:
- Web applications: cross-browser/platform, user flows, security and performance risks
- APIs (REST/GraphQL): request/response validation, error handling, response times, data correctness
- Databases: data integrity, consistency, accuracy, resilience under volume and change
- Performance: front-end/back-end response and behaviour under load; document results and insights
Use diagnostic tools and system documentation to identify, diagnose, and report system errors.
Provide advice and guidance to colleagues on test planning and execution; help prioritise testing work to meet milestones.
Collaborate continuously with developers and specialists to drive requirement clarity and a quality-first mindset.

What you’ll bring

Strong knowledge of QA methodologies and processes (ad-hoc, exploratory, equivalence partitioning, risk-based testing).
Experience working in Agile/Scrum and/or DevOps delivery environments.
Ability to write clear, concise, and comprehensive test artefacts (test cases, charters, plans, evidence, reports).
Experience with BDD and converting scenarios into executable specifications (feature files + step definitions).
Automation experience using tools/frameworks such as Behave, Cucumber, Pytest-BDD, Cypress, with Python as a core language.
Practical experience with Selenium, Postman, and GraphQL tooling.
Familiarity with test/defect tracking tools (e.g., Jira).
Understanding of CI practices and how automated tests should run in pipelines for fast feedback.
Good understanding of testing layers (unit, integration, end-to-end) and the ability to advise what should be tested as part of a cohesive strategy.
Strong collaboration, communication, and stakeholder management skills.

Desirable

Experience creating a Test Automation Strategy / Approach / Plan.
Proven track record writing API automation tests and contributing to an API testing framework/standards.
Experience collaborating with engineers to build API integration test suites in Cypress.

Working style

You’re proactive, structured, and thorough. You can break down complex work into clear steps, communicate effectively in writing, build strong relationships across disciplines, and escalate risks early to keep delivery on track.
