- Lead DevSecOps evolution across devnets, testnets, and mainnet, including launch readiness and upgrade paths.
- Own the infrastructure security posture across environments.
- Integrate security into the delivery lifecycle, including: secure CI/CD pipelines, secrets and key management, access control and IAM, node and peer identity handling.
- Harden infrastructure against Web3-specific threats (DDoS, eclipse/sybil patterns, replay attacks, resource exhaustion).
- Set DevSecOps standards for infrastructure-as-code and orchestration (Terraform, Kubernetes, Helm).
- Ensure fast, reproducible, and auditable deployments across environments.
- Drive DevSecOps automation as a first-class principle.
- Define and own SLOs/SLIs around: propagation latency (including tail behavior), availability and fault tolerance, peer churn, packet loss, and network stability.
- Build reliability processes suitable for mission-critical mainnet systems.
- Own build, release, and rollout pipelines (e.g. GitHub Actions).
- Enforce artifact integrity, versioning, controlled rollouts, and fast rollback paths.
- Balance velocity with production safety.
- Partner closely with protocol engineers and researchers to productionize new networking and RLNC-based capabilities.
- Work with product and BD to ensure infrastructure constraints and guarantees are well understood.
- Provide infrastructure input to roadmap, launch planning, and external commitments.
- Leading company wide security practices & provide educational awareness of new threats.
- Own on-call strategy, escalation paths, runbooks, and incident communication.
- Lead post-mortems focused on systemic improvement.
- Establish a culture of operational discipline.
- Stay hands-on where it matters: build internal tools, automation, and operators (Go, Python, Bash).
Requirements
- 8+ years in Infrastructure, SRE, or DevOps roles, including ownership of DevSecOps in production systems.
- Demonstrated experience operating distributed systems at scale, ideally in Web3 or similarly adversarial environments.
- Proven experience leading incidents, setting reliability standards, and interfacing with non-infra teams.
- Strong security mindset applied to infrastructure and delivery workflows.
Benefits
- Competitive compensation package, including token incentives.
- Remote-first environment with flexible hours.
- High ownership role with real influence on protocol success.
- Close collaboration with world-class researchers and protocol engineers.
