Time ZoneUS Time Zone (PST - EST)
Role OverviewThis role sits at the intersection of AI engineering and platform development. As a Senior AI Platform Engineer, you will own the contextual intelligence layer that powers our AI agents — ensuring they understand, reason, and act with precision across our SaaS ecosystem.
You will work at the cutting edge of how structured knowledge is used to make AI agents smarter and more reliable. This is a role for an engineer who thinks deeply about context, meaning, and how machines can be equipped to make better decisions — and who can also build the frontend surfaces that make those capabilities accessible to end users.
Key Responsibilities
* Design and maintain semantic context layers — knowledge graphs, ontologies, and structured context stores — that inform agent behaviour

Tips for South African Applicants
Timezone Advantage
South Africa (SAST, UTC+2) overlaps well with European business hours and has a few hours of overlap with US East Coast. Mention your timezone flexibility in your application.
Salary in Context
At R46,250/month, this role is competitive with the average South African remote salary. The USD equivalent ($2,500/mo) benefits from the favourable exchange rate.
Application Tips
Tailor your CV to international standards — use a clean format, highlight remote work experience, and include your English proficiency. Many SA applicants succeed by emphasising their strong work ethic and cultural adaptability.
Load Shedding Preparedness
If you're applying for a remote role, having a backup power solution (UPS, inverter, or generator) and mobile data as a backup internet connection shows employers you're prepared for South Africa's infrastructure challenges.
