Jobbeschreibung

You will design and operate high availability backend services for investment platforms and help build a new channel that connects investment capabilities to external clients through e-banking. The team works across Zurich and Singapore, and the role offers scope to shape a strategic platform from an early stage.

• Design distributed systems that balance scalability, latency, consistency and fault tolerance; apply idempotency, back pressure and resilience patterns to financial workloads.
• Build and maintain Java, Spring and Spring Boot services and APIs, and optimise asynchronous processing, I/O and end to end performance.
• Develop reliable integration and messaging flows using relational databases, JPA, JDBC and JMS; protect data integrity, security and auditability.
• Investigate bottlenecks with profiling, benchmarks and load tests; own solutions from design through deployment and production support.
• Work with product and technology colleagues on the client channel, contributing to reviews, testing, CI/CD and controlled delivery.

Requirements

• Senior level Java experience, including Core Java, Collections, JSON and JDBC, with strong Spring Framework and Spring Boot skills.
• Proven distributed systems and microservices experience, including event driven design and low latency, high availability services.
• Practical knowledge of relational databases, JPA, JMS, Unix or Linux and bash scripting, plus OAuth2, API security and IAM concepts.
• Familiarity with cloud platforms (ideally Azure), Docker, Kubernetes and DevOps practices; financial sector experience is an advantage.
• Ownership, sound judgment and a collaborative approach in a global agile team.
• Two home office days per week.
• Initial 12 month contract with the possibility of extension.
• Early influence on the architecture of a strategic client facing investment channel.
• Collaboration with an international team in Zurich and Singapore.
