API Platform Engineer (George Western Cape, On-site)

API Platform Engineer

Softsure | George, Western Cape | In-Office

Turn a Monolith into a Platform Others Can Build On

At Softsure we’re not just modernising a system, we’re turning it into a platform.

That means APIs, consistent, secure, versioned and documented.

At Softsure, our platform has been running for 15 years. It works but it’s time to evolve. We’re moving toward an API-first, event-driven architecture that enables the entire group to build faster and integrate seamlessly.

This role is about defining what “good” looks like and making sure it’s the standard.

What You’ll Do

You’ll own and shape the API layer of the platform:

• Define and enforce API design standards aligned with OpenAPI 3.1

• Architect and manage Azure API Management (APIM) across internal and external APIs

• Design API versioning strategies that enable evolution without breaking consumers

• Build API templates and code generators for consistency and speed

• Implement API security standards (OAuth 2.0, JWT, rate limiting, IP restrictions)

• Establish contract testing practices to prevent breaking changes

• Build and maintain the API documentation portal

• Act as the quality gate, reviewing APIs before production release

• Create mock services to enable parallel development

• Define integration patterns across systems within the Group

Engineering Contribution (Non-Negotiable)

You’re not just defining standards, you’re building:

• Design, develop, and maintain production-grade APIs using C# and ASP.NET Core

• Contribute to backend engineering and platform development efforts

• Build reusable API components, templates, and frameworks

• Participate in code reviews, testing, and engineering best practices

• Support the modernisation of legacy systems into API-driven services

What You Bring

• 5+ years experience in API development or API platform engineering

• Proven experience building and maintaining API platforms at scale

• Deep understanding of REST principles and real-world application

• Hands-on experience with Azure API Management (or similar gateways)

• Ability to design and write OpenAPI specifications from scratch

• Strong understanding of API security (OAuth 2.0, OpenID Connect, JWT, threat modelling)

• Proficiency in C# and ASP.NET Core Web API

• Experience with API testing and contract testing tools

Education

• Degree or Diploma in Computer Science, Information Technology, Software Engineering, Computer Engineering, or a related technical field

Advantageous:

• Certifications in cloud platforms, API management, or platform engineering (Azure preferred)

• Equivalent practical experience building and maintaining production APIs and distributed systems will be considered.

Nice to Have

• Experience with GraphQL or gRPC

• Event-driven API patterns (webhooks, AsyncAPI)

• Exposure to Backstage or developer portals

• Insurance / integration standards knowledge (ACORD)

• Experience driving API standardisation across teams

Why Join Softsure

• Define the API strategy for an entire platform, work with Azure APIM and modern tooling

• Build APIs that become the integration backbone of the Group

• Join a team that treats APIs as products, not afterthoughts

• Play a key role in transforming a legacy system into a modern platform

Location

George, Western Cape (In-Office) We believe the kind of engineering required to build something meaningful happens best together.

Final Word

This role is for someone who:

• Knows the difference between an endpoint and a product

• Designs APIs people actually want to use

• Can bring structure to complexity at scale

If you’ve built APIs that others depend on then we should talk.
