The Role

This is a software engineering role, not a traditional IT or DevOps position. We are looking for a Platform Engineer who loves to build products for other developers.

Your "product" is the entire developer experience (DevEx) for our R&D department. Your "customers" are all the other engineers in teams like Tenants, Assets, and Market. Your mission is to build the tools, abstractions, and self-service platforms that make our developers faster, safer, and more productive.

You won't just run RabbitMQ; you will build the "Queue (RabbitMQ) as-a-platform" that other teams consume. You won't just use an API gateway; you will build and maintain the "API gateway as-a-platform" that defines our standards. You will write high-quality, scalable code (using our company stack: TypeScript, Node.js, Nest.js) to create the internal tools that power our entire R&D organization.

While this is a remote-first role, you should be based in a CET-adjacent timezone to collaborate effectively with colleagues. You can also expect to travel for periodic in-person team gatherings.

What You'll Do

• Build 'as-a-Platform' Services: Design, code, and maintain the self-service platforms that all our engineers rely on. This specifically includes:
  • API gateway as-a-platform
  • WebSocket API as-a-platform
  • Queue (RabbitMQ) as-a-platform
  • User log processing as-a-platform
• Engineer the CI/CD Platform: Act as a core developer and maintainer of our CI/CD platform, building reusable pipelines, deployment patterns, and automation.
• Improve Developer Experience: Build the tooling and automation that defines and improves our development experience, from local setup to production.
• Infrastructure as Code (IaC): Work with the team to manage and scale our foundational AWS services (k8s, databases, cache, vault) using code (e.g., Terraform).
• Maintain Standards: Help build the tooling that defines and enforces API standards, version control policies, and best practices.

• Reliability: Participate in on-call rotations and help lead incident response procedures and post-mortems.

   

What We're Looking For

• Software Engineer First: You are a strong software engineer with 3+ years of experience, preferably with TypeScript/Node.js, who is passionate about infrastructure.
• Platform Experience: You have a proven track record of building internal tools, developer platforms, or CI/CD systems. You treat "infrastructure" as a "product."
• DevOps/Infra Skills: Deep, hands-on experience with AWS, Kubernetes, and IaC (e.g., Terraform, Pulumi).
• CI/CD Expert: Experience building and managing complex CI/CD pipelines (e.g., GitLab CI, GitHub Actions, Jenkins).
• "Customer" Empathy: You have a product mindset and genuine empathy for your "customers" (other developers) and their experience.
• Location: Based in a timezone adjacent to Central European Time (CET) for optimal team collaboration.
• Problem Solver: You are an autonomous problem-solver who can take a high-level goal (e.g., "we need a better API gateway") and own it from design to production.

Bonus Points

• Experience building custom API gateways or platform abstractions.
• Deep knowledge of our specific infra stack: RabbitMQ, PostgreSQL, Redis.

• Experience in a FinTech or high-security environment.

   

What We Offer

• Foundational Role: A unique opportunity to be a founding engineer building the entire developer platform for a high-growth FinTech.
• High-Impact: Your work will directly accelerate every other engineer in the company.
• Clear Ambition: The chance to join a company with a clear goal of becoming the #1 crypto platform in the EU.
• Greenfield Culture, Brownfield Code: A rare chance to join a new company culture with no baggage, while solving the interesting technical challenges of a mature product.
• Flexibility & Connection: A 100% remote-first role with periodic, all-expenses-paid team gatherings and a new hub in Ticino, Switzerland.
• Compensation: A competitive salary and benefits package.

The Role

We are looking for a highly skilled Senior DevOps Engineer to strengthen our Cloud Platform team. This is a hands-on technical role critical to ensuring our operational excellence, security, and resilience.

You will help build a secure, scalable, and compliant cloud infrastructure that serves as the foundation for all our product teams. This role requires deep hands-on experience with AWS, Kubernetes, and Infrastructure-as-Code.

Crucially, you will be responsible for navigating the strict regulatory landscape of a financial institution. You must have successfully navigated environments requiring ISO 27001, PCI DSS, and DORA compliance. You will work closely with the Cloud Platform Manager and security teams to implement the controls and processes necessary to keep our platform secure and compliant.

While this is a remote-first role, you should be based in a CET-adjacent timezone to collaborate effectively with colleagues.

What You'll Do

• Build Cloud Infrastructure: Design, implement, and maintain our AWS-based infrastructure (EKS, EC2, RDS, IAM, VPC, KMS, networking).
• Infrastructure as Code (IaC): Develop and manage our infrastructure using Terraform/Terragrunt, Helm, and Kubernetes manifests.
• CI/CD & GitOps: Build and optimize CI/CD pipelines (GitHub Actions/GitLab CI) and operate GitOps workflows using ArgoCD or Flux.
• Compliance Implementation: Implement and maintain the specific technical controls and processes required for ISO 27001, PCI DSS, and DORA.
• Security Operations: Apply best practices for cloud security, encryption, access control (IAM, RBAC, Zero Trust), and support incident response.
• Observability: Configure and maintain our observability stack using Prometheus, Grafana, Loki, Alloy, and OpenTelemetry.
• Documentation: Create clear technical documentation, standards, and security policies to support audits and internal knowledge sharing.

• Disaster Recovery: Support Disaster Recovery (DR) and Business Continuity planning and testing.

   

What We're Looking For

• Experience: 5+ years of professional DevOps experience, with a proven track record of building secure cloud environments.
• Compliance Expert: Mandatory hands-on experience implementing and passing audits for ISO 27001, PCI DSS, and DORA. You must understand the technical reality of these frameworks.
• AWS Mastery: Deep experience with AWS services, particularly EKS, networking, and security.
• Certification: AWS Certified Solutions Architect – Associate (Mandatory).
• Container Orchestration: Expert-level knowledge of Kubernetes (EKS), including autoscaling, IRSA, network policies, and cluster security.
• IaC Expertise: Strong proficiency with Terraform / Terragrunt and GitOps methodologies.
• Observability: Experience with monitoring, logging, and distributed tracing tools (Prometheus, Grafana, Loki).
• Security Mindset: Solid understanding of networking (TLS, VPN, WAF) and identity management (IAM, RBAC).

• Soft Skills: Strong ownership mentality, proactive problem-solving, and the ability to communicate effectively with auditors and stakeholders.

   

Bonus Points

• Certifications: AWS Security Specialty, AWS DevOps Engineer (Professional), or CKA/CKAD (Kubernetes).
• Familiarity with MiCA (Markets in Crypto-Assets) regulations.
• Experience with Vault, AWS Secrets Manager, or SSM Parameter Store.
• Experience building AWS Landing Zone / Control Tower architectures.

• Background in FinTech, RegTech, or enterprise banking environments.

   

What We Offer

• Foundational Role: A key role in building the compliant infrastructure backbone for a major European crypto platform.
