About the Role:

While primarily remote, this role requires occasional visits to the office in Coimbra. We plan to open offices in Aveiro and Porto in the future. This approach gives team members the flexibility to work remotely while also coming together in the office for collaboration and teamwork.

The Unite Services & Unite Integrations teams build and operate the backend platforms that power the Unite app (messenger) and integrations ecosystem. This includes:

• Integration APIs and microservices
• Multi-region Kubernetes clusters (cloud & on-prem)
• CI/CD and GitOps tooling (GitHub-centric)
• Internal Developer Platform (IDP) components
• Critical shared infrastructure (RTE, Redis, Harbor, Consul, Chart Museum, API Gateway, etc.)

We are looking for a Sr. DevOps Engineer, Team Lead to take over the hands-on technical and leadership scope: owning reliability, security, and operational efficiency for Unite Services & Unite Integrations, while leading a small DevOps team.

You will be the go-to person for Kubernetes, GitHub-based CI/CD, disaster recovery, security hardening, and platform-wide DevOps practices.

What you will be doing:

Team Leadership & Ownership

• Lead and grow a small DevOps engineering team supporting Unite Services and Unite Integrations.
• Drive team planning and execution across operational efficiency, security, reliability, and platform maturity epics (e.g., quarterly OKRs/initiatives).
• Provide technical mentorship on Kubernetes, GitHub, CI/CD, and cloud infrastructure.
• Collaborate closely with Engineering, SRE, Security, and Ops on roadmap, incident resolution, and cross-team initiatives.

Platform Operations (UST / Unite Services / Integrations)

• Own the operational health of Unite Services and Unite Integrations: Lead production deployments and release processes for backend services (e.g., Unite Notifications, integrations platform, Salesforce-related services).
• Oversee multi-environment support (DEV/QA/PROD and special environments like RTE).

Kubernetes, Cloud & On-Prem Infrastructure

• Operate and evolve Kubernetes clusters (cloud and on-prem), including:
  • Cluster upgrades and migration playbooks
  • Ingress/Nginx and service mesh / networking changes
  • Resource/capacity optimization (CPU throttling, scaling, etc.)
• Manage supporting infrastructure for Unite platforms:
  • Redis, Consul, Harbor, Chart Museum, API gateways, message queues (e.g., RabbitMQ)
• Contribute to and adopt Internal Developer Platform (IDP) capabilities (e.g., API Gateway, Apache Flink management, Crossplane-based infrastructure).

CI/CD, GitOps & Tooling

• Lead migration and consolidation of repos and pipelines to GitHub (from TFS/Azure DevOps and others).
• Design, implement, and maintain GitHub-based CI/CD:
  • GitHub Actions workflows
  • Self-hosted GitHub runners (including K8s-based and Windows runners)
  • Versioning and branching strategies
• Introduce and maintain GitOps practices for infrastructure and application deployments.
• Automate repetitive tasks and operational workflows via scripting and infrastructure-as-code.

Security, Compliance & Reliability

• Drive security initiative epics (e.g., Ransomware preparedness, vulnerability remediation like Redis Lua RCE, tagging in Qualys/CrowdStrike).
• Work with Security to design and implement:
  • Rate limiting, WAF rules, and API protection (e.g., Cloudflare for SCIM and public APIs)
  • Secrets management and secure configuration
• Define and execute disaster recovery and ransomware recovery strategies for UST / Unite Services / Integrations.
• Improve reliability and quality of platforms via SLIs/SLOs, operational runbooks, and post-incident improvements.

Observability, Incident Management & Runbooks

• Own observability for Unite Services and Unite Integrations:
  • Metrics, logs, traces (e.g., Prometheus, Grafana, ELK, etc.)
  • Dashboards for capacity (Kubernetes CPU usage, throttling, etc.) and error budgets
• Lead incident response for platform issues:
  • Triage, mitigation, communication, and follow-up actions
  • Coordination with product/engineering teams during outages
• Create and maintain detailed runbooks and recovery procedures, especially for:
  • RTE environment, K8s clusters, Harbor, Consul, Chart Museum
  • Disaster recovery and ransomware scenarios

Documentation & Process

• Produce and maintain clear, actionable documentation:
  • Infrastructure design and configuration
  • CI/CD and GitOps processes
  • Recovery and maintenance procedures
  • RFCs for new platform capabilities (e.g., API Gateway, Apache Flink)
• Contribute to process improvements in CI/CD, deployment strategies, and developer experience.
• Help define and maintain product maturity models for Unite Integrations and related platforms.

What you will bring to the role:

Technical Skills

• Strong background in platform / DevOps engineering for complex distributed systems.
