Platform Engineer (Go)

Our mission is to enable everyone to build wealth. We reinvent how trading and investing work by creating exceptional products people love. Fostering a culture of excellence and high velocity is the key to our success. Today, we serve over 5 million clients, with more than €30 billion in assets under management - a testament to the scale and trust we’ve built in just a few years.

Our Platform Engineering team is the foundation upon which our product is built. We design, build, and maintain the core developer experience, shared services, and tooling that enable our product teams to ship features quickly, reliably, and at scale. We are looking for an engineer who is passionate about automation, developer productivity, and building robust, scalable systems.

What You’ll Do

• Develop platform solutions with a holistic approach - Understand the challenges of our product engineering teams, our service architecture, and the underlying cloud infrastructure to build tools and automation that deliver a world‑class developer experience.
• Take full ownership of the platform's lifecycle - Engage directly with internal teams to define requirements, design elegant solutions, code them (primarily in Go), test them, and manage their deployment and operation.
• Build for reliability, scalability, and security – Design infrastructure, tools, or core libraries that are highly available, resilient, and secure by default.
• Work in compact, autonomous teams with short release cycles - Rely on agile, independent teams of sharp and driven people with just the right amount of processes to steer off anarchy and not sacrifice velocity.
• Learn from your colleagues and share your knowledge with them.

What You Need To Have

• A mindset for building tools and APIs for other developers.
• Professional experience building and shipping application‑level code to production with Go.
• A good understanding of common service‑to‑service communication patterns (e.g., HTTP, gRPC, messaging queues).
• Familiarity with building framework‑level components.
• Strong understanding of Go concurrency patterns and performance optimisations.
• Practical, hands‑on experience with Kubernetes.
• An ability to work autonomously.
• A knack for problem‑solving, debugging, and figuring out “weird stuff.”
• Enthusiasm and curiosity.

Nice to have

• Experience designing and maintaining reusable Go libraries or SDKs.
• Production experience with messaging brokers (e.g., Apache Kafka, RabbitMQ).
• Background in supporting critical production services.
• Experience developing custom Kubernetes controllers or other Kubernetes native APIs.
• Hands‑on experience with cloud platforms and their services (e.g., AWS, GCP).
• Experience building monitoring, alerts, and dashboards for proactive insights into system health.
• Experience building internal developer portals.
• Experience in building and managing CI/CD pipelines with GitHub Actions or similar tools.
• No fear of using OS primitives.
• Familiarity with Cloud Native projects, service mesh technologies or observability stacks.
