DevSecOps Engineer

Join our Team

About this opportunity:

BNEW RCE Lab Operations provides lab infrastructure, networks, and hardware services that enable R&D teams to configure and deploy design and test environments globally. 

Hardware Management (HWM) provides hardware asset management for R&D, covering the full asset lifecycle to support data-driven decisions and maximize value. 

Join Ericsson as a DevSecOps Engineer and help build, secure, and operate COS (Central Observability System), the platform behind our global observability services used by thousands of developers and testers worldwide. 

We’re hiring a DevSecOps Engineer to evolve and run COS (Central Observability System), Ericsson’s global observability platform. Join our journey into secure automation and AI-enabled operations. 

COS is used daily by thousands of developers and testers worldwide. You’ll own the DevSecOps setup end-to-end: secure CI/CD, infrastructure/configuration as code, operational readiness, and continuous improvement. You’ll also help introduce AI, from AIOps workflows to MLOps/LLMOps pipelines keeping features safe, observable, and reliable. 

Tech stack spans cloud-native microservices (e.g., Go, Svelte, Kubernetes), telemetry backends (e.g., Cortex), and data systems (e.g., Postgres/Cassandra/Kafka). 

You like automation, clear guardrails, and measurable outcomes. You turn telemetry into action and help teams move fast without compromising security or reliability. 

What you will do 

• Build and run COS as a secure cloud-native platform (containers, Kubernetes, OpenStack), using infrastructure/configuration as code. 


• Introduce AI-enabled operations (AIOps) and MLOps/LLMOps practices: automate detection/diagnosis, and set up safe, observable delivery and monitoring of AI components. 


• Execute deployments, upgrades, and configuration changes; troubleshoot by reproducing issues, restoring service, and running performance/load tests as needed. 


• Improve secure CI/CD for platform and services: testing, scanning, policy checks, controlled releases, and compliance (risk assessments, audits, configuration baselines). 


• Apply SRE practices to improve availability, scalability, and performance, and drive proactive monitoring and reliability improvements. 


• Take operational ownership with the team: runbooks, on-call readiness, incident/problem management, SLA follow-up, access management, and service performance reporting. 

The skills you bring

• 5–8+ years in DevSecOps or platform engineering in a cloud-native environment, with end-to-end ownership across build and run. 


• Strong CI/CD and automation skills, including security checks (SAST/SCA, image scanning, policy checks) and controlled releases. 


• Solid understanding of cloud-native observability (Grafana, Prometheus, Loki) and instrumentation with OpenTelemetry. 


• Comfortable working across a broad tech stack and learning new tools and concepts quickly. 


• Clear communicator who collaborates globally and can explain our work across development, operations, and security. You enjoy mentoring and sharing practices in the team/community. 


• Proactive problem-solver who thrives in hands-on engineering and structured delivery, and enjoys making production systems secure, predictable, and observable. 


• Merit: AI platform engineering (MLOps/LLMOps), deploying/monitoring LLM services, RAG pipelines, and embeddings/vector search. Ericsson experience is a plus.
