Senior Systems Engineer (SRE Golang) to £130k

Are you an experienced Systems Engineer with a strong knowledge of modern software infrastructure and robust APIs?

You could be progressing your career in a hands-on Senior Systems Engineer at a scaling FinTech that is developing a fast, secure cross-border payments platform that is designed for ultra low-cost, near-instant money transfer at significantly higher transaction sizes than what's currently possible, with a mission to break down the barriers that have held back African businesses for decades.

As a Senior Systems Engineer you'll design and build the infrastructure that runs production applications while contributing directly to the backend codebase. Working primarily with Go, you'll tackle technically challenging problems across authentication, security, networking and WebSockets, with the opportunity to understand and influence systems right down to the operating system level.

Reliability will be central to everything you do. You'll design systems with the assumption that failures will happen, building resilient, adaptable and highly available services, working across performance, observability and security, using logs, metrics and traces to understand system behaviour and correlate technical performance with business outcomes. You'll also work with Infrastructure as Code such as Terraform and Kubernetes, with a genuine understanding of what sits underneath these abstractions.
