DevSecOps Engineer - Part-Time

Position Overview

We are seeking an experienced DevSecOps with Observability Engineer to join our team

and drive the implementation of secure, scalable, and comprehensively observable

cloud infrastructure. The successful candidate will be responsible for building and

maintaining CI/CD pipelines, implementing security controls throughout the

development lifecycle, and establishing enterprise-grade observability practices that

provide deep insights into system performance, security posture, and operational

health across our entire technology stack.

Key Responsibilities

Infrastructure & Cloud Management Design, implement, and maintain cloud

infrastructure on AWS using Infrastructure as Code principles. Manage containerised

applications using Amazon EKS and ensure optimal performance, security, and cost

efficiency. Collaborate with development teams to architect scalable solutions that

meet both functional and non-functional requirements whilst embedding observability

from the ground up.

Security Controls Implementation Implement and maintain security controls

throughout the development lifecycle, from code commit to production deployment.

Integrate automated security testing, static and dynamic code analysis, and

vulnerability scanning into CI/CD pipelines. Establish security gates and approval

processes that prevent vulnerable code from reaching production environments.

Develop and enforce security policies for container images, infrastructure

configurations, and application deployments with comprehensive security

observability.

Advanced Monitoring & Observability Design and implement enterprise-grade

observability solutions using ELK Stack or Prometheus-Grafana to provide

comprehensive insights into system performance, security events, and operational

health. Architect distributed tracing solutions using OpenTelemetry to monitor

application performance across complex microservices architectures and troubleshoot

issues with precision. Create sophisticated dashboards, alerts, and reporting

mechanisms that provide actionable insights to stakeholders whilst ensuring security

events, performance anomalies, and operational issues are proactively identified and

investigated. Implement observability-driven incident response and post-mortem

processes.

CI/CD Pipeline Management Build, maintain, and optimise CI/CD pipelines using

GitLab Runners to enable rapid, reliable, and secure software delivery. Embed security

controls and observability instrumentation at every stage of the pipeline including pre-

commit hooks, automated security testing, compliance checks, and deployment

validation. Implement automated testing, security scanning, and deployment

processes that support continuous integration and deployment practices whilst

maintaining zero-trust security principles and comprehensive pipeline observability.

Infrastructure as Code & Policy as Code Implementation Leverage Infrastructure as

Code tools, particularly Terraform, to automate infrastructure provisioning and

management with built-in security controls, compliance checks, and observability

instrumentation. Implement Policy as Code frameworks to codify governance,

compliance, and security policies that are automatically enforced across all

infrastructure deployments. Develop custom automation scripts and tools to

streamline operational processes whilst ensuring security standards and observability

requirements are maintained. Integrate and utilise GenAI-based coding agents to

enhance development productivity and code quality, implementing appropriate security

guardrails and observability for AI-assisted development.

Observability Strategy & Implementation Develop and execute comprehensive

observability strategies that encompass metrics, logs, traces, and events across the

entire application and infrastructure stack. Implement service level objectives (SLOs)

and service level indicators (SLIs) to measure and improve system reliability. Design and

maintain observability platforms that support real-time monitoring, historical analysis,

and predictive insights for both operational and security use cases.

requirements codified and enforced through Policy as Code implementations

• Understanding of network security, identity and access management, and data

protection defined and managed through Infrastructure as Code templates and

policy definitions

• Experience with security orchestration and incident response procedures

automated and standardised through Infrastructure as Code and Policy as Code

frameworks

Professional Experience

• Minimum 5 years of experience in DevOps, SRE, or similar roles with security and

observability focus

• Minimum 2 years of hands-on Terraform experience in production environments

• Proven track record of implementing and managing secure cloud infrastructure

at scale with comprehensive observability

• Experience working in agile development environments with security integration

and observability practices

• Strong problem-solving skills and ability to work under pressure whilst

maintaining security standards and observability requirements

Preferred Qualifications

• AWS certifications (Solutions Architect, DevOps Engineer, or Security Specialty)

• HashiCorp Certified: Terraform Associate or Professional certification

• Observability and monitoring certifications or demonstrable experience

• Experience with Terraform Enterprise or Terraform Cloud

• Experience with additional monitoring tools, APM solutions, and observability

platforms
