Job description

Lenstra was founded by passionate computer science engineers with a proven track record of delivering high-quality solutions. By combining technical excellence with a strong vision, we support top-tier clients across industries such as Banking & Insurance, Luxury, and Technology.

Our expertise is structured around four core pillars: Software Development, DevSecOps, Data & AI, and Product. Through a holistic understanding of our clients’ environments, we help them address their most complex challenges—from building robust software and secure cloud platforms to designing data-driven solutions that accelerate business impact.

The role is part of the Platform Engineering team - the core of products delivering by providing a reliable, secure, and scalable cloud platform. As a DevOps Engineer (AWS/Terraform), your mission is to design, industrialise, and operate the platform and tooling that enable teams to build, deploy, and evolve their applications quickly and safely on AWS.

Key tasks

As a Cloud Data Platform Engineer, you will have the following tasks:

• Design and develop advanced, reusable Terraform modules (networking, security, compute, data, edge) aligned with robust architectural standards and AWS best practices
• Evolve a multi-account (AWS Organisations, Control Tower/SCPs, governance, identities) to provide a secure, scalable deployment framework
• Define infrastructure and application blueprints(“golden paths”) for containerized (EKS/ECS/Fargate), serverless (Lambda), and traditional (EC2/ASG) workloads, including networking, observability, and security
• Build and maintain CI/CD pipelines for infrastructure and applications
• (Jenkins/GitLab CI), including testing, policy-as-code (OPA/Conftest), security (tfsec/Checkov), and automated plan/apply (Atlantis/Spacelift/Terraform Cloud)
• Operate and harden the platform: monitoring/alerting/logging/tracing
• (CloudWatch, OpenTelemetry, Prometheus/Grafana, OpenSearch, Datadog), SLI/SLO definition, capacity management, backups and disaster recovery
• Secure the environment: least-privilege IAM, KMS, Secrets Manager, patching, secret management (SOPS), IaC/image scanning
• Manage Terraform at scale: remote state (S3 + DynamoDB locking), versioning strategy, module lifecycle, multi-environment patterns, drift
• detection/remediation
• Identify and automate repetitive tasks (Bash/Python tooling, Terraform
• automation, or AI copilots) to accelerate deployments and migrations
• Contribute to L2/L3 support, incident management and post-mortems; produce clear documentation and ensure knowledge transfer

Required skills:

• Minimum 3 years in DevOps/SRE/Platform Engineering and at least 2 years of hands-on production experience on AWS.
• Bachelor’s or Master’s degree in Computer Science/Engineering (or equivalent).
• Strong mastery of Terraform: module design, providers, state management, structure and best practices, testing and release.
• Deep AWS expertise: VPC/Transit Gateway, IAM, EC2/ASG, EKS/ECS/Fargate, RDS, DynamoDB, S3, ALB/NLB, Route 53, Lambda, CloudWatch, Systems Manager, KMS, Organisations/Control Tower.
• Solid Linux, networking (TCP/IP, DNS, TLS), and scripting (Bash); Python for tooling and integrations.
• Strong DevOps practices and CI/CD experience; Git, MR/code review.
• Containers and orchestration (Docker, Kubernetes/EKS), packaging (Helm),registry and supply chain security.
• Excellent collaboration skills; ability to translate product needs into simple, robust, secure technical solutions.
• Fluent in English and French.
