Help Power the Infrastructure Behind the Future of Digital Assets
At OnchainLabs, we’re reshaping how businesses engage with customers through digital assets — from branded wallets and loyalty programs to product passports and verified ownership. WalletTwo is our universal wallet infrastructure that makes Web3 invisible, intuitive, and frictionless.
We’re scaling rapidly and need someone to help us maintain and optimize the physical backbone of it all — our server operations hub in Sanlúcar de Barrameda
Your Role
We’re hiring a DevOps Developer with hands-on experience managing physical server infrastructure. You’ll work closely with our CTO and engineering teams to ensure our systems run with maximum reliability, security, and performance — directly from our data hub in Spain.
You will:
• Manage and optimize our physical server infrastructure, with additional responsibilities across cloud environments.
• Execute hardware and software upgrades, monitor uptime, and manage system performance
• Build and manage CI/CD pipelines, monitoring tools, and backup solutions
• Ensure compliance with internal security and redundancy protocols
• Collaborate with our remote team on backend integration and performance tuning
• Manage local networking and connectivity systems
What You Bring
Proven experience in DevOps or system administration roles with physical infrastructure
• Strong knowledge of Linux server management, virtualization, Docker, and networking
• Experience setting up and maintaining CI/CD pipelines (e.g., GitHub Actions, Kubernetes, Docker, Javascript)
• Understanding of system security, firewalls, and data backup strategies
• Fluent in English and preferably conversational in Spanish
• Located in or nearby Sanlúcar de Barrameda, Spain — this role is fully on-site
Bonus Points
• Familiarity with blockchain environments or secure, high-availability systems
• Experience with monitoring tools (e.g., Prometheus, Grafana)
• Scripting abilities in Bash, Python, or similar
• You like organizing cables (you know who you are)
What You Get
• Join a fast-growing, well-funded startup on the cutting edge of digital engagement
• Work closely with an expert international team across product, blockchain, and design
• Take pride in owning a mission-critical part of our infrastructure
• Modern, respectful working culture
