What will you do?

We are looking for an engineer who will own the end-to-end evaluation, design, and implementation of security and observability solutions for a container-based private cloud platform. This role spans the full lifecycle — from architectural research and tool selection through production deployment and ongoing operations — across unified telemetry, security detection, vulnerability management, supply chain security, and automated incident response.

You will be the technical owner of the platform's observability and security monitoring stack, working across platform engineering, security operations, and SRE teams to deliver a unified telemetryfirst architecture.

Evaluation & Research

• Conduct structured evaluation of candidate tools against criteria including license compliance, community governance, vendor independence, and technical fitness
• Perform proof-of-concept exercises to validate architectural decisions (e.g. ingestion throughput, storage efficiency, query
• latency, operational complexity)
• Assess and track governance posture of selected tools; maintain contingency paths for vendor-led dependencies
• Engage with upstream open-source communities and foundations to stay current on project maturity and roadmap changes

Design & Architecture

• Design unified telemetry pipelines using open standards to serve both SRE observability and security operations from a single data layer
• Architect security detection workflows using vendor-neutral detection languages to ensure portability of detection content across backends
• Design vulnerability aggregation and management workflows spanning container scanning, software composition analysis, static analysis, infrastructure vulnerability scanning, and software bill of materials generation
• Design supply chain security controls including image signing, provenance attestation, and registry policy enforcement
• Design exposure path analysis using graph-based tooling to map relationships across compute orchestration, identity, source control, and vulnerability data
• Design automated remediation and orchestration workflows integrated with alerting, ChatOps, and ticketing
• Produce and maintain architecture decision records documenting design rationale, trade-offs, and change history

Implementation & Operations

• Deploy and operate the observability stack: telemetry collection, columnar storage, dashboarding, metrics scraping, alerting, and log routing

• Deploy and operate the security monitoring stack: endpoint/hostbased detection, detection rule evaluation, vulnerability aggregation, and infrastructure scanning
• Deploy and operate CI pipeline security scanning: container image scanning, dependency scanning, SBOM generation, static analysis, infrastructure-as-code scanning, and secrets detection
• Implement image registry security with integrated vulnerability scanning and admission policy enforcement
• Implement identity, directory, secrets management, and certificate lifecycle infrastructure
• Implement collaboration and incident management tooling (ChatOps, ticketing)
• Build and maintain detection rules, alerting rules, and automation playbooks
• Operate all components on a container orchestration platform with fleet-wide deployment tooling

Process & Governance

• Define and document operational runbooks for each capability area
• Establish and maintain vendor-independence contingency entries for all vendor-led tools
• Conduct periodic licence and governance re-assessment of selected tools
• Collaborate with legal/compliance on copyleft licence reviews before deployment
• Define SLOs for telemetry pipeline availability, ingestion latency, and detection coverage
• Participate in security incident response using the tooling you build and operate

Required Skills & Experience

• 5+ years in platform engineering, SRE, or security engineering roles
• Strong hands-on experience with at least 3 of the following:
• Telemetry collection frameworks and instrumentation standards
• Columnar or analytical databases for log/trace/event storage
• Metrics scraping and alerting ecosystems
• SIEM operations and detection engineering (vendor-neutral detection rule formats preferred)
• Search-based log analytics platforms (to understand migration context)
• Production experience deploying and operating on Kubernetes or equivalent container orchestration platforms
• Experience with container security scanning and software composition analysis tooling
• Familiarity with supply chain security concepts: SBOM, image signing, provenance attestation, admission control
• Experience with at least one SOAR or automation/orchestration platform
• Solid understanding of log collection and routing architectures
• Experience writing detection rules or correlation logic for security monitoring
• Ability to evaluate open-source projects for governance health, license risk, and production readiness
• Strong Linux systems fundamentals

Preferred Skills

• Experience with host-based intrusion detection or endpoint detection and response tooling
• Experience with graph databases and asset/infrastructure relationship mapping
• Familiarity with vulnerability management and aggregation platforms
• Experience with identity providers, directory services, and secrets management
• Contributions to open-source security or observability projects
• Experience operating in government or regulated environments with strict vendor-independence or sovereignty requirements
• Familiarity with enterprise Linux and container platform ecosystems
• Experience with GitOps workflows for deploying infrastructure services
• Static/dynamic application security testing tooling experience

Qualifications

• Bachelor's degree in Computer Science, Cybersecurity, Information Systems, or equivalent practical experience
• Relevant certifications are a plus but not required (e.g. Kubernetes security, Linux administration, offensive security, or cloud security specializations)

What do we offer in return?

• Fun working environment
• Employee Wellness Program
• To work in Singapore Government Agencies projects
• We provide structured development framework and growth opportunities. (We are a “SHRI 2025 Gold winner” in “Learning & Development; Coaching & Mentoring”)
