The OpportunityHelp build the systems that keep millions of payments safe. Electrum processes financial transactions for millions of South Africans every day. We are looking for a software engineer who wants to spend their time building the libraries, tooling, and automation that make secure code the default across Electrum. This is a hands-on engineering role. You will design and ship internal platforms that other engineering teams depend on. You will be the person who makes "doing the secure thing" the easiest path for every developer at Electrum not by writing policy documents, but by writing code. If you are a strong backend or platform engineer who has been gravitating toward security work and wants to make it your specialism, this role is built for you. The RoleYou'll spend most of your time shipping code on projects like: • Secure-by-default Java libraries for encryption, authentication, and logging that every product team in the company builds on top of. • An AI-assisted code review system that runs against high-impact pull requests, flagging real security issues without drowning teams in noise. • Kubernetes admission controllers and IDE tooling that catch security problems before code is ever committed, shifting feedback from CI/CD into the developer's editor. • Automated remediation pipelines that don't just find vulnerabilities but actually fix them like having dependency upgrades and configuration drift handled without human intervention. • Self-service security platforms that replace manual reviews with proper internal tooling teams can use to assess their own posture. • Pipeline integrations that pull signals from security solutions and underlying infrastructure into a single coherent picture for engineering teams.
