Requirements and responsibilities
Readable role content extracted into sections for faster review.
You will ensure:
- High-quality, secure, and scalable infrastructure capable of supporting modern applications and advanced AI workloads
- Robust automation across CI/CD, infrastructure provisioning, and operations to increase reliability and reduce manual overhead
- Thoughtful and pragmatic integration of AI into operational workflows to improve efficiency, detect anomalies, and accelerate delivery
- Reliable systems engineering practices, including monitoring, incident response, performance tuning, and capacity planning
- Strong DevOps standards, including reproducibility, testing, documentation, and operational excellence
- Clear technical communication and cross-team alignment to enable predictable delivery and collaborative problem-solving
- Mentorship and technical leadership that elevates platform engineering, DevOps maturity, and overall engineering quality across the organisation
Outcomes:
- Conduct a full review of Sleek’s cloud infrastructure and propose a roadmap for reliability and scalability improvements
- Lead upgrades or redesigns of core platform components such as networking, containers, orchestration, or databases
- Improve incident response processes, SLIs, SLOs, and on-call readiness.
Outcomes:
- Ensure platform and infrastructure are capable of supporting AI-powered features
- Build or refine pipelines for model hosting, embeddings, vector search, or related AI services if required
- Implement monitoring and guardrails for AI service performance, cost, and stability
Increase Engineering Velocity Through Automation
- Enhance CI/CD pipelines for speed, safety, and reliability
- Introduce infrastructure automation, testing automation, and deployment tooling to reduce manual steps
- Champion modern DevOps and AI-assisted tooling to improve engineering productivity.
Improve Observability and Operational Excellence
- Strengthen logging, monitoring, tracing, and alerting across services
- Reduce noisy alerts and improve the signal-to-noise ratio for incidents
- Implement readiness checks, runbooks, and automated recovery paths for critical services
Security and Compliance Improvements
- Ensure secure configuration, secrets management, access control, and identity management
- Implement automated security scanning, dependency monitoring, and hardened pipeline practices
- Prepare platform-level requirements needed for reliable and secure AI usage
To do this you will have:
- 6+ years of progressive experience in Site Reliability Engineering (SRE)
- 6+ years of strong, hands-on experience across multi-cloud environments such as AWS, GCP, Azure including expertise in networking, compute, storage, security, and cost optimization.
- 6+ years of deep expertise in containerization and orchestration (e.g., Kubernetes, EKS, ECS)
- 6+ years of extensive experience with Infrastructure as Code (IaC) (e.g., Terraform, Pulumi, CloudFormation).
- System Reliability: Proven ability to design, build, and operate highly reliable, scalable production systems utilizing advanced Zero-Downtime Deployment Patterns (e.g., Blue/Green, Canary, progressive delivery).
- Modern Delivery & Tooling: Expertise in modernizing deployments via GitOps practices (e.g., ArgoCD, Flux) and building Self-Service Developer Platforms that enable engineering efficiency (e.g., environment automation, internal tooling).
- Networking & Edge Routing: Experience implementing and managing Multi-Cloud API Gateways and Edge Routing solutions (e.g., Kong, Traefik, Cloudflare, multi-cluster ingress).
- Security & Hardening: Strong background in platform security, including secrets management, Identity and Access Control (IAM), and Runtime/Security Hardening with tools like Falco/eBPF and WAFs.
- Observability: Solid understanding and practical experience with modern observability stacks (e.g., Prometheus, OpenTelemetry, OpenSearch, ELK, CloudWatch).
- AI/ML Infrastructure: Experience supporting or deploying AI/ML workloads (e.g., model inference, vector databases, GPU workloads), or strong familiarity with the infrastructure requirements for these systems.
- Communication: Excellent communication and collaboration skills with a proven ability to describe complex infrastructure decisions clearly and a background in driving improvements in engineering practices.
- Development Expertise: Familiarity with modern programming languages like Node.js, NestJS, and Python is highly desirable for extending DevOps capabilities or integrating tooling.
