Senior Devops Engineer; Remote - EU

The employer develops a breakthrough high-performance onchain exchange that delivers institutional grade execution, whilst delivering superior speed, security and reliability guarantees to users. Their revolutionary decentralized exchange operates as the world's first trading‑specific Based Rollup on Ethereum offering core competitive advantage:
Unlike traditional Layer 2 solutions that rely on single sequencers, Based Rollup grants transaction sequencing rights directly to Ethereum validators, achieving true decentralization.

• Speed: < 1ms trade execution (100 times faster than top DEXs)
• Security: verifiable order execution and settlement via zk‑proofs, with executed trades settling on Ethereum. Over 950,000 Ethereum validators securing every transaction. Transaction data ultimately settles on Ethereum mainnet, inheriting all L1 security guarantees.
• Reliability: No single point of failure, with the rollup design having multiple rotating L2 nodes (unlike generation‑1 rollups)

Their custom trading engine is written in Rust, achieving deterministic execution. Their engine is cross‑compiled into zero‑knowledge circuits, allowing the network to generate validity proofs for each state transition, ensuring provably correct order execution.

They’re looking for a Senior Dev Ops Engineer based anywhere in Europe (Remote), to join their team.

As a Senior Dev Ops Engineer, you will play a pivotal role in building and maintaining the infrastructure that powers the company's DeX and Network. Your mission is to ensure systems are secure, scalable, and highly available — enabling the team to deliver quickly without sacrificing reliability.

You thrive in a small, highly skilled team dealing with complexity, unknowns, and rapid iteration.

You enjoy automating away toil and creating scalable, self‑healing systems.

You are excited by the opportunity to help shape the future of finance through reliable, secure infrastructure.

You embrace end‑to‑end ownership of systems, from design to monitoring to incident response.

Design, implement, and maintain cloud‑native infrastructure using Infrastructure as Code (IaC). Build scalable, reproducible environments that support high-throughput, low‑latency trading systems.

Own and improve the CI/CD pipelines for backend, frontend, and smart contract codebases. Ensure fast, reliable builds and deployments with strong observability and rollback mechanisms.

Define and implement monitoring, logging, and alerting strategies to achieve maximum system reliability and early incident detection. Drive SLO/SLI/SLAs and participate in on‑call rotations.

Optimize infrastructure for latency‑sensitive workloads. Tune autoscaling policies, network configurations, and resource utilization to ensure consistent performance during peak loads.

Implement robust security practices across infrastructure, CI/CD, and runtime environments. Protect systems from evolving threats through network segmentation, secret management, and runtime hardening.

Establish and maintain playbooks, failover mechanisms, and disaster recovery plans. Lead post‑incident reviews and proactively address root causes.

Continuously monitor and optimize cloud costs while ensuring performance and redundancy requirements are met.

Stay current on infrastructure tooling, orchestration frameworks, and security best practices. Evaluate new technologies for potential adoption to improve performance and resilience.

Maintain clear, detailed documentation for infrastructure, processes, and runbooks. Mentor engineers and help foster a culture of reliability and automation across the team.

• 8+ years of experience in Dev Ops, SRE, or infrastructure engineering roles in high‑availability, mission‑critical systems with prior Web3 and trading experience
• 6+ years of experience with major cloud platforms (AWS and GCP)
• Experience supporting low‑latency trading systems or other real‑time financial applications
• Familiarity with blockchain infrastructure,…
