About the Role

Job Title: QA Engineer
Location: unspecified
Employment Type: Full-time
Department: unspecified

As our QA Engineer, you’ll be the champion for product quality across a fast-moving platform built for engineers and QAs. We’re expanding the team so our automated testing can keep pace with the rapid growth of our hybrid architecture—SaaS control plane plus on-premises agent data plane. Reporting to the Head of Engineering, you’ll design the quality strategy, build the tooling, and lay the foundations for a future QA team with a growth path toward Lead/Manager as we expand.

Core Responsibilities

• Define and own the end-to-end test strategy for both control-plane (cloud) and data-plane (agent) components.
• Design, implement, and maintain multi-layer automation—UI (Playwright/Selenium), API/contract, integration, and distributed-system scenarios.
• Build a protocol-level test harness for our remote-agent communication, including fault-injection and network-chaos cases.
• Embed quality gates and trend reporting into our GitHub Actions CI/CD pipeline.
• Partner with Product Manager and Solution Architects to clarify acceptance criteria, surface risks, and verify real-world workflows.
• Leverage observability-driven testing (logs, traces, metrics) to detect hidden regressions and performance bottlenecks.

About You

• Obsessed with quality and user experience for developer-oriented tools.
• Solid hands-on experience in software testing/quality engineering, preferably within cloud-native or hybrid/edge architectures.
• Understanding of modern testing theory.
• Proficiency automating tests in Kotlin or Java (JUnit, Testcontainers, REST-assured/Ktor tests) and UI automation with Playwright or Selenium.
• Comfort validating distributed systems: asynchronous protocols, chaos/failure scenarios.
• Familiarity with Docker/Kubernetes and infrastructure-as-code to spin up realistic test topologies.
• Fluent with CI/CD tools like GitHub Actions.
• Experience using observability stacks (OpenTelemetry, Prometheus, Grafana) to derive test assertions.
• Clear, concise communicator able to collaborate effectively with engineers, PMs, Solution Architects, and (occasionally) customers.
• Security, compliance, or data-privacy testing exposure is a plus (our agents run inside customer networks).

What We Offer

• Wonderful office in the heart of Shoreditch, hybrid 3-days 🏢
• Generous cash compensation and share options 💰
• Flexible work hours ⏰
• Personal development budget (coaching, courses, events) 📚
