Senior DevOps Engineer

Lisk is building a modern financial platform for businesses that integrates crypto infrastructure. They are seeking a Senior DevOps Engineer to help evolve their cloud infrastructure, ensuring security, reliability, and efficiency as they scale their services.

Responsibilities:

• Work as part of a tight-knit platform team
• Drive the platform roadmap
• Own our Infrastructure as Code
• Run production at a fintech bar
• Lead on security
• Build safe delivery pipelines
• Make the platform observable
• Plan for failure
• Control cost
• Raise the team's bar

Requirements:

• 5+ years in DevOps / SRE / SysOps / Platform Engineering, with significant ownership of production AWS environments
• Deep, hands-on AWS. Real depth across IAM, compute, networking, managed databases, storage, secrets, and observability, not just 'I've used the console.'
• Expert in Infrastructure as Code, specifically Terraform or OpenTofu, covering modules, remote state, drift management, and managing multiple isolated environments from one codebase
• Strong security instincts. You design least-privilege by default, think in blast radius, and have managed secrets and credentials for systems that matter. You can explain why a permission exists
• CI/CD fluency, ideally GitHub Actions, including OIDC / keyless cloud authentication
• Production operations maturity. Observability, alerting, incident response, backups, and disaster recovery, all as lived experience
• A bias for shipping. You deliver, you don't just advise, bringing a track record of actually shipping hardening, migration, and reliability work, not only designing it
• Self-sufficient in a lean team. Comfortable owning large areas independently on a small platform team, without needing a big platform org around you to be effective
• Remote-first working style. Clear written communication, self-direction, and comfort owning outcomes across time zones
• Ability to work with significant overlap (at least 4–6 hours) with European business hours to collaborate effectively with the team
• Experience in FinTech, payments, banking, or another regulated/high-trust environment (SOC 2, ISO 27001, PCI-DSS, or similar compliance exposure)
• Web3 / crypto infrastructure experience running nodes, managing keys and HSMs, and securing systems that touch on-chain assets
• Threat modeling, security audits, or formal incident-response leadership
• Database operations depth (Postgres tuning, zero-downtime migrations)
• Kubernetes, service mesh, or large-scale container orchestration
• Cost-optimization wins you can point to
• Network architecture at scale: multi-account/Transit Gateway or VPC peering, private egress design, or hardening east-west traffic between services
• Exposure to a second cloud (GCP/Azure) or genuine multi-cloud networking, useful as a signal of provider-agnostic IaC and network design, even though our stack is AWS-first today
