• Monitoring: Experience with observability tools such as Sentry, Prometheus, and Grafana.
• Soft Skills: Clear, proactive communication skills suited for a distributed, async-first team and a strong ownership mindset.
• Web3 Knowledge: Hands-on experience with blockchain systems, dApps, or smart contracts is highly preferred.
• Bonus Qualifications: Knowledge of Golang, prior experience in a high-autonomy startup environment, and location within time zones close to Europe (CET/EET).
