Senior Software Engineer (Go) - Platform API

As a Senior Go Engineer on the Platform APIs Team, you’ll work on some of our company’s most pivotal distributed services, where performance, scalability, and reliability are paramount. Our engineers are encouraged to tackle projects independently, with collaborative opportunities for solving complex challenges, brainstorming new designs, and discussing innovative ideas. You’ll play a key role in maintaining high-performance standards and contributing to cost-efficient optimisations that impact the entire platform. Design, develop, and optimise high-performance Go-based microservices, essential to transaction management and payment processing. Push the boundaries of CockroachDB with efficient database configurations and high-performing queries to support scalability and speed. Optimise inter-service communication using NATS for low-latency and distributed processing. Continuously refine services to balance cost-efficiency with high performance, maintaining strict availability and performance SLOs. Maintain high availability standards in a Kubernetes multi-cloud environment, operating across AWS, Azure, and GCP. The Platform APIs Team is responsible for low-latency, mission-critical, stateful services that support our payments infrastructure 24x7, 365 days a year. Engineers on the team take individual ownership of tasks, focusing deeply on optimisation and scalability to ensure these services operate seamlessly at high volumes. Running active-active across multiple clouds in Kubernetes, these services present complex, fascinating challenges in distributed computing. This work offers an excellent grounding in high-transaction, distributed cloud architecture on Kubernetes. The team’s culture values collaboration for complex problem-solving, architectural decisions, and innovations in scaling and cost-efficient improvements, providing a supportive environment where expertise is shared and ideas are developed together.
