Senior Engineer, Site Reliability

Role Description

The Senior SRE – Applications will design and implement automation, CI/CD tooling, and resilient infrastructure for Syniti's cloud-hosted SaaS platform (SKP Northstar). This role sits within the Application SRE team, supporting 79+ microservices across data migration, quality, matching, orchestration, and catalog product lines. The engineer will lead Azure environment buildout while maintaining and improving existing AWS infrastructure, supporting Northstar's global compliance and scalability objectives including FedRAMP High, Cyber Essentials+, and SecNumCloud adherence. The role requires close collaboration with development, infosec, platform SRE, and compliance teams to enforce Zero Trust patterns and observability across all layers of the stack.

What You Will Do

• Design and build automated cloud infrastructure for Syniti-hosted SaaS workloads across Azure and AWS.
• Implement and manage CI/CD pipelines using GitHub Actions and ArgoCD GitOps workflows for multi-environment deployments (dev, preprod, prod, GovCloud).
• Develop and maintain Terraform modules for infrastructure provisioning, including EKS/AKS clusters, Aurora PostgreSQL, Redis, OpenSearch, and S3/Azure Storage.
• Integrate and maintain observability frameworks (Prometheus, Grafana, Loki, Mimir, Jaeger) and enforce structured logging of application, audit, and security events.
• Support and extend Istio service mesh configurations including mTLS policies, AuthorizationPolicies, and SPIFFE-based workload identity.
• Implement and maintain supply chain security controls: container image signing (Cosign), SBOM generation (Syft), provenance attestation (SLSA), and vulnerability scanning (Trivy, Inspector, Snyk).
• Collaborate with security teams to meet FedRAMP High, Cyber Essentials+, NIST 800-53, and SecNumCloud control objectives across Azure and AWS environments.
• Provide L3 incident response and lead root cause analysis efforts for application-tier outages across the Northstar platform.
• Support the automated compliance gate (11 controls: NAC, FIPS, STIG, IRSA, SAST, DAST, SBOM, Sign, Vuln, Audit, Auth) and ensure application services pass all gates.
• Manage Kubernetes workload autoscaling (Karpenter, KEDA, HPA) and pod security policies (Kyverno) for production services.

Qualifications

• Strong communication skills and ability to operate in a globally distributed team.
• Ability to work across development, compliance, platform SRE, and infrastructure teams.
• Self-starter with strong service ownership and ability to handle on-call escalations autonomously.
• Commitment to continuous improvement and infrastructure-as-code principles.
• Solid documentation skills for runbooks, architecture decisions, and operational procedures.

Requirements

• 10+ years of experience in SRE, DevOps, or Cloud Engineering.
• 5+ years of hands-on experience with Microsoft Azure including AKS, Storage, Monitor, and IAM/Entra ID.
• 3+ years of hands-on experience with AWS (EKS, RDS/Aurora, IAM, S3, SQS, Cognito).
• 3+ years of Terraform module development for cloud infrastructure provisioning.
• 3+ years in CI/CD tooling (GitHub Actions, ArgoCD, or equivalent GitOps platforms).
• Strong Kubernetes operations experience: cluster management, pod security, autoscaling, troubleshooting.
• Experience with service mesh technologies (Istio, Envoy, or Linkerd) and workload identity (SPIFFE/SPIRE, IRSA, or workload identity federation).
• Proficiency in scripting languages: Python, Bash, or PowerShell. Go or .NET experience a plus.
• Experience implementing regional compliance controls (FedRAMP, SOC 2, Cyber Essentials+, or equivalent).
• Understanding of Zero Trust principles, mTLS, service identity, and network segmentation.
• Experience with observability stacks (Prometheus, Grafana, Loki, or equivalent) and distributed tracing.
• Familiarity with container supply chain security (image signing, SBOM, vulnerability scanning) is a plus.
