- Platform Engineering is the backbone of Trade Republic’s engineering velocity. Our mission is to build scalable platforms for a Europe-scale bank — serving internal engineers, and building in-house control planes for managing the bank’s infrastructure
- We’re a ~50-person Platform team focused on one thing: enabling product engineers to move fast and operate autonomously by default
- We build self-service platforms, golden paths, and opinionated tooling so that over 400 engineers can ship with confidence
- From Kubernetes fleet management and CI/CD to an internal Developer Hub built on Backstage, our work underpins every trade, savings plan, and card payment that flows through the platform
- Kafka is becoming the central nervous system of Trade Republic — connecting trading, banking, financial crime detection, and more in real time
- Today, scaling our Kafka infrastructure to match the pace of the business means too much manual work, too much operational toil, and not enough time building the platform it could be
- We are changing that — treating Kafka clusters as fungible shards of a larger resource pool, with a Temporal-backed control plane, Backstage-integrated self-service, and transparent multi-cluster routing that gives product engineers a zero‑config experience
- Run Kafka at scale: Own the reliability and uptime of our Kafka fleet — design for high availability across domains and shards, engineer for resilience, and ensure near-zero downtime across maintenance, upgrades, and failure scenarios
- Build the streaming platform: Design and implement the control plane that makes the multi-cluster platform real — cluster lifecycle automation, topic and ACL provisioning, cross-shard replication, and the self-service interfaces that let product engineers onboard without understanding the infrastructure underneath
- Make streaming best practices the default: Define standards for how product engineers produce and consume — topic design, schema management, consumer group patterns, and reliability practices — and embed them into the platform so the right thing is always the easiest thing
- Own the platform end to end: Participate in the on-call rotation, ensuring full ownership of the systems you build and operate
- Own the direction: Shape the roadmap, drive cross-team initiatives, and align the streaming platform with broader engineering and business goals
Qualifications
- We are hiring from senior to staff level — whether you are a strong Kafka engineer ready to take on platform ownership, or you have already been leading streaming platform strategy across large engineering organisations, we’d love to hear from you
- Solid backend engineering background — Go is preferred xuezdbg but any strong language is welcome; familiarity with Kotlin/JVM is a plus as you’ll work directly with product teams who rely on it
- A track record of turning streaming best practices into opinionated standards that engineering teams actually adopt
- Deep, hands‑on Kafka expertise: you have run self‑hosted Kafka in production and have strong opinions on cluster architecture, scaling, replication, multi‑cluster design, performance tuning, and security
- 4+ years of experience in streaming, platform engineering, or a related systems discipline
- Cloud‑native in your DNA: hands‑on with Kubernetes and IaC tooling, running production workloads on AWS or equivalent
- Ability to drive cross‑team initiatives and clearly communicate architectural trade‑offs to both engineers and leadership
- The ability to work in a flexible hybrid setup, with 2‑3 days a week in the office
