Job Description

About the role

You'll join Devoteam's engineering practice and work across client engagements — from financial services to large enterprises — where the infrastructure actually matters. You'll be embedded in cross-functional teams, shaping DevOps standards from the ground up, not inheriting someone else's neglected setup.

What you'll do

• Design, build, and own CI/CD pipelines across multiple projects and platforms (GitLab CI, GitHub Actions, Jenkins), from initial design to production;
• Automate deployment and infrastructure release workflows, cutting manual toil and reducing the surface area for human error;
• Define and implement observability strategies covering metrics, logs, and distributed traces so issues are caught before users notice them;
• Design, implement, and operate Kafka-based data pipelines and real-time messaging infrastructure supporting critical business operations;
• Write Infrastructure as Code using Terraform or OpenTofu, paired with configuration management via Ansible, Salt, or Puppet;
• Investigate platform incidents end-to-end and own the resolution — including writing the post-mortem and updating the runbook;
• Actively contribute to Devoteam's internal DevOps community through code reviews, knowledge-sharing sessions, and internal talks. 

Stack & technical environment

• Core: Linux (advanced administration), Kubernetes (senior level), Docker, Helm;
• Security hardening: AppArmor, SELinux, Seccomp, eBPF;
• Messaging & streaming: Apache Kafka, Kafka Streams, KSQL, Apache Flink;
• IaC & config management: Terraform, OpenTofu, Ansible, Salt, Puppet;
• CI/CD: GitLab CI, GitHub Actions, Jenkins;
• Scripting: Bash, Python, PowerShell;
• Networking: Traffic management, secure protocols, storage architectures.

Qualifications

What we're looking for

Must-have:

• 3+ years of hands-on experience in DevOps, SRE, or platform engineering roles;
• Senior-level Kubernetes experience, including hardening (AppArmor, SELinux, Seccomp, eBPF);
• Solid IaC background: proven experience designing pipelines, not just maintaining them;
• Experience designing and operating Kafka-based architectures for real-time data processing;
• Comfortable owning infrastructure documentation — if it isn't written down, it doesn't exist;
• Fluent in both written and spoken French and English.

Nice to have:

• Certifications: CKA, CKAD, CKS, or equivalent cloud certifications (AWS, Azure, GCP);
• Experience with DevSecOps tooling: Trivy, Falco, OPA/Kyverno, HashiCorp Vault;
• Familiarity with service mesh solutions: Istio or Linkerd;
• Authentication/authorization protocols: OIDC, SAML, RBAC, ReBAC;
• Prior experience in regulated environments (banking, financial services).

Soft skills: Self-starter | Able to explain technical trade-offs to non-technical stakeholders | Quick to ramp up in new team and technical environments
