Senior Fullstack Devloper

Senior Fullstack Product Engineer (Fullstack, AI-native) Remote (Netherlands) | €100k | Take initiatives from PRD to production with AI coding agents for a trading SaaS | Fintech / trading | CQRS, Kafka, Angular, Kotlin, GCP
Do you enjoy owning an initiative end to end, from PRD to production, instead of just shipping code? Do you get energy from building event-driven systems with Kafka, CQRS and event sourcing?
Our client is a fast-growing fintech start-up building a SaaS platform for high-frequency, high-velocity traders. The platform empowers more than 10,000 active traders in over 100 countries to monetize their trades efficiently and securely. The backend consists of 20 microservices built in Kotlin with Kafka as the messaging layer, all hosted in GCP on Kubernetes. The company is in a maturing phase: the real-time, high performance platform is live and growing, and there is a lot of room to drive new initiatives.
Your role:
As a Senior Product Engineer you take product initiatives from PRD to production, using AI coding agents to deliver fast without cutting corners. Think new challenge plans, and integrations with new trading platforms or external systems. You turn a PRD into a technical design first, deciding which services, events and read models change and how the change rolls out, then build it across the stack: Kotlin and Spring Boot on the backend, Angular and TypeScript on the frontend, with Kafka for event sourcing, CQRS and event-driven architecture.
You run several agents like Claude Code in parallel, split work into well-scoped tasks, give them good context, and review and verify everything they produce. 'The agent wrote it' is never an excuse. You work by the test pyramid, plan safe releases with migrations, feature flags and rollbacks, and pick up production incidents and alerts independently.
What's asked:
- 5+ years of backend development experience in a statically typed language, with willingness to read and work in Kotlin and Spring Boot
- 3+ years building and running production systems with event sourcing, CQRS and Kafka.
- Able to deliver in Angular, or in React with TypeScript with willingness to work in Angular
- Daily, hands-on use of agentic coding tools such as Claude Code, running several agents in parallel and owning what they ship
- Proven broad-scope experience in small teams or start-ups, owning design, build, release and operations without a dedicated PM, QA or DevOps team
Benefits:
- Salary up to €100k annually
- 23 vacation days
- Pension scheme
- Remote first role with flexible working hours, mostly in CET hours
- International team with growth opportunities
