Job description

Founded in 2003, our client is a South African specialist software vendor known for providing elegant solutions to complex business challenges, backed by deep technical and operational expertise. They provide managed investment administration platforms for financial institutions, integrating investor and portfolio management with compliance and reporting.

Job Type: Full Time

Workplace: Remote

Working Hours: Monday to Friday, 09:00–16:00 SAST

Role Overview

Our client is seeking experienced mid-to-senior software engineers or infrastructure specialists who are excited by the challenge of building and operating a complex, business‑critical managed service used daily by hundreds of users.

You will join a highly skilled team and apply your expertise in infrastructure engineering, automation tooling, systems design, and operational resilience. Their environment offers opportunities to work on everything from CI/CD pipelines and container orchestration to configuration management, infrastructure as code, and observability tooling. While you may bring experience in specific tools or platforms, you will be expected to contribute broadly across the infrastructure landscape.

Our client’s core product is a comprehensive administration platform delivered as software‑as‑a‑service to leading South African investment and wealth management firms. Their mission is to provide a platform that leads the market in accuracy, resilience, and functionality.

As a cloud‑hosted solution, their stack includes modern tooling across CI/CD, containerization, monitoring, and cloud infrastructure. You will help build, maintain, and evolve this environment to meet high standards of performance, reliability, and security.

They make extensive use of automation tools such as Terraform and Ansible, alongside programming in Python. Their environments are entirely based on Ubuntu Linux. Experience with server monitoring software (e.g. Prometheus, Grafana, Zabbix, Datadog) and a solid understanding of security principles and best practices (including hardening, access control, auditing, and incident response) is highly valued.

This is a remote‑first role, and they are looking for individuals who can thrive in a distributed work environment. You must be able to work independently, manage your time effectively, and take initiative in progressing your tasks. Clear communication and self‑direction are essential.

Our client is headquartered in Johannesburg, South Africa, but operates as a fully distributed team. You can work from anywhere with a timezone within 3 hours of South African Standard Time. You must be available during our core business hours (Monday to Friday, 09:00–16:00 SAST). The full team meets annually for planning and social events, with additional in‑person collaboration among Johannesburg‑based staff.
