What is Accountable?
Accountable is a young fintech/taxtech focused on helping the self-employed automate their accounting and taxes with a simple mobile and web app. We are 80+ people spread across offices in Berlin and Brussels, as well as remote locations throughout Europe. We aim to create a product that is incredibly easy and fun to use, requiring no knowledge of tax or accounting. We're growing at a rate of more than 150% per year, and our ambition is to become the European leader in our market.
The Role
We are seeking a Platform Engineer to own and evolve our Kubernetes-based infrastructure on AWS. You'll be responsible for ensuring our microservices platform is reliable, scalable, and cost-efficient while empowering developers to ship with confidence. Our stack runs on AWS EKS with modern tooling including Karpenter for intelligent node scaling, KEDA for event-driven autoscaling, and Datadog for full observability. If you enjoy working with Kubernetes at scale and have a passion for automation, we'd love to hear from you.
What You'll Do
* Own our Kubernetes platform: Manage and evolve our AWS EKS cluster, including node pools, networking, scaling policies, and cluster upgrades
* Optimize autoscaling: Configure and tune Karpenter (node-level) and KEDA (pod-level) to handle traffic spikes efficiently while minimizing costs
* Build reliable CI/CD pipelines: Design and maintain GitHub Actions workflows for building, testing, and deploying containerized microservices to production
* Drive observability: Own our Datadog implementation for logs, APM, metrics, and alerting—ensuring we catch issues before our users do
* Manage secrets securely: Maintain our secrets management flow using AWS Secrets Manager and External Secrets Operator
* Support the development team: Collaborate with backend engineers on Node.js/TypeScript services, helping debug performance issues and optimize deployments
* Maintain supporting infrastructure: Manage Redis clusters (used for Bull job queues), ALB ingress configuration, and DNS management
* Implement Infrastructure as Code: Use Helm, Kustomize, or Terraform to ensure our infrastructure is reproducible and version-controlled
* Respond to incidents: Troubleshoot production issues, conduct post-mortems, and implement preventive measures
* Optimize costs: Monitor and reduce AWS spending through right-sizing, spot instances, and efficient resource allocation
Required Qualifications
* 4+ years of hands-on experience with Kubernetes (AWS EKS strongly preferred)
* Strong Kubernetes fundamentals: Deployments, Services, Ingress, ConfigMaps, Secrets, RBAC, NetworkPolicies
* Experience with Kubernetes autoscaling: HPA, VPA, KEDA, or Karpenter
* AWS proficiency: EKS, ECR, ALB, Secrets Manager, IAM roles for service accounts, EventBridge, SQS, Lambda
* CI/CD expertise: Building and maintaining pipelines with GitHub Actions for containerized workloads
* Observability experience: Datadog, Prometheus/Grafana, or similar (logs, metrics, APM, alerting)
* Container expertise: Docker, multi-stage builds, image optimization, container registries
* IaC experience: Terraform
* Scripting skills: Bash, Python, or similar for automation tasks
* Working knowledge of Node.js/TypeScript: Enough to read code, debug issues, and collaborate with developers
* Redis experience: Job queues, caching, basic administration
* Strong communication skills: Ability to work effectively with distributed teams across Europe
Nice-to-Have
* AWS certifications (Solutions Architect, DevOps Engineer, or Kubernetes specialty)
* Experience with GitOps workflows (ArgoCD, Flux)
* MongoDB administration experience
* Service mesh experience (Istio, Linkerd)
* FinOps / cost optimization expertise
* Experience with security scanning (Trivy, Snyk, etc.)
* CI/CD experience for mobile applications (React Native)
* Familiarity with compliance requirements in fintech
