The Nym team is a world-class mix of privacy experts, engineers, and thinkers spread across Europe. We believe that user privacy underpins democratic freedoms in a networked world, and we're proud to help roll back the surveillance society.
We're looking for a SDET to lead the testing of our decentralised VPN across multiple platforms (Windows, macOS, iOS, Android, Linux). You’ll be the technical authority for ensuring performance, reliability, and security across complex distributed systems, with strong ownership of automation, networking validation, and DevOps integration.
In the first month you might
- Set up and stabilise test environments across all supported platforms (Windows, macOS, Linux, Android, iOS)
- Build or improve automated test cases for VPN tunnels, networking flows, and security protocols
- Investigate cross-platform connectivity issues and contribute to root cause analysis
- Collaborate with engineers to define test strategies for upcoming decentralised networking features
Key Responsibilities
- Cross-Platform Testing: Design and implement test strategies for 5+ platforms; build automated test suites using WebDriverIO (web) and Appium (mobile).
- Networking & VPN Validation: Test tunnel stability, peer discovery, routing, and encryption protocols (WireGuard, OpenVPN, IPSec); troubleshoot DNS and network issues.
- DevOps & CI/CD: Manage automated test pipelines (GitHub Actions/GitLab CI); provision containerised environments (Docker); support CI for multi-platform builds.
- Diagnostics & Incident Response: Investigate critical bugs, network failures, and performance bottlenecks; lead root cause analysis and improve observability.
- Collaboration & Process: Partner with engineering teams to drive continuous improvement in test reliability and coverage.
Technical Skills
- Automation: Strong in Appium and WebDriverIO; experience with API testing, scripting (TypeScript/JavaScript, Bash), and CI/CD.
- Networking: Deep understanding of VPN protocols, NAT/firewalls, DNS, routing, and P2P networking.
- Systems & CLI: Comfortable across Windows/macOS/Linux; proficient with shell scripting, Docker/Kubernetes, and system admin tools.
- Tooling: Prometheus, Grafana, Wireshark, tcpdump, Terraform, Ansible, AWS.
Requirements
- Proven experience testing complex networked systems and VPNs.
- Hands-on with distributed system testing, cross-platform QA, and environment configuration.
- Strong DevOps and CI/CD practices in production environments.
Nice to Have
- Experience with blockchain, Tor/I2P, mesh networking.
- Security or compliance knowledge (e.g. data privacy, regulatory frameworks).
- Background in load testing and performance tuning.
What we offer you:
- A diverse, global team of 50+, interested in learning and solving problems together.
- 6 Weeks annual leave plus national holidays.
- Yearly learning and development allowance.
- IT hardware package tailored to your role.
- Remote working (with a bias towards being able to do in-person meetups periodically).
- A competitive salary.
