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.
