Opensee a décidé de s’attaquer à l’un des défis majeurs des institutions financières : prendre les décisions les plus éclairées, de la manière la plus simple et la plus rapide possible.
Comment ? En exploitant l’intégralité de leurs données.
Opensee, avec ses experts du secteur financier et de la deep tech, offre aux banques et gestionnaires d’actifs un accès simple et instantané à leurs données massives (en Téra) et rompt le statu quo :
- En abattant les silos,
- En questionnant les processus existants,
- En établissant des partenariats solides avec ses clients pour développer les solutions les plus adaptées.
Aujourd’hui, cette Fintech internationale en pleine expansion offre une solution performante aux grandes institutions financières sur Paris, Londres et New-York.
Vos missions au quotidien
About the role
We build analytics software for some of the world’s largest financial institutions. Our clients historically ran our products on-premises; today a growing share of them run on our cloud SaaS platform, in dedicated single-tenant environments on AWS and GCP.
Our DevOps team runs that platform end to end: dozens of Kubernetes environments across many cloud accounts, deployed through GitLab CI/CD, OpenTofu and Ansible. We are looking for a DevOps engineer to help us scale and harden it, with a strong focus on platform security, disaster recovery and production readiness.
You will join a small, experienced team where knowledge sharing and open communication matter as much as technical depth. You will support both client-facing and internal environments, and you will grow into owning key areas of the platform, with senior engineers to learn from.
What you’ll do
- Operate and improve our fleet of Kubernetes (EKS) environments: upgrades, scaling, and rolling out releases across client environments.
- Contribute to platform security: secrets management, IAM, network exposure, WAF, and fixing cloud security posture findings.
- Help implement disaster recovery for client environments: backups and regular restore drills.
- Build alerting and dashboards on our self-hosted Grafana/OpenTelemetry stack, and take part in incident response.
- Write and review infrastructure as code (OpenTofu, Ansible, Helm) and improve our GitLab CI/CD pipelines.
- Support internal teams and client environments, and document what you build.
Our Technical stack:
- DevOps: GitLab, GitLab CI/CD, Docker, Kubernetes, Helm, Terraform, Grafana, OpenTelemetry
- Cloud: AWS, Azure, GCP
- Security: HashiCorp Boundary, Vault, Keycloak, AWS WAF&Shield, Cloud Armor
- Coding & Scripts: Python, Bash, Go
Ce que l’on cherche
About you
- 3+ years in DevOps or SRE, including hands-on work on production cloud environments.
- Hands-on AWS experience: IAM, networking, and EKS or another managed Kubernetes service.
- Kubernetes in production: deploying with Helm and troubleshooting workloads.
- Infrastructure as code with Terraform or OpenTofu.
- Ansible, or a similar automation tool and the willingness to learn Ansible.
- Scripting in Bash and Python.
- Security awareness: secrets management, least privilege and network exposure.
- Good written and spoken English.
Nice to have
- Go, for building internal tooling or Kubernetes controllers.
- Experience operating a SaaS product for a commercial software company.
- AWS multi-account setups and IRSA.
- A Grafana / OpenTelemetry observability stack (Mimir, Loki, Tempo).
- Cilium, Karpenter or other advanced Kubernetes networking and autoscaling tools.
Why join us
You will shape a SaaS platform that some of the most demanding financial institutions rely on, with growing ownership and a team that values sharing what it knows. If that sounds like you, we’d love to hear from you.
