Job description

Techno Park, Stellenbosch – My client, a well‑established engineering company is seeking to employ a Senior Software and Systems Architect with at least 8 years' substantial professional software experience in ownership of production applications as well as Senior development, technical lead, software architect or comparable role to join their team.

The main purpose of this role is to take technical ownership of the architecture, design, development, and evolution of software platforms and supporting systems. The primary focus is full stack software architecture and hands‑on development, covering back‑end services, databases, APIs, integrations, and web applications. The role also provides senior technical ownership of ICT infrastructure, security, and operational practices required to deliver dependable systems. This is a hands‑on technical leadership position with responsibility throughout the software lifecycle—from requirements and architecture through development, deployment, support, and continuous improvement

Requirements:

• A degree or diploma in Computer Science, Software Engineering, Electronic Engineering, Information Technology or a related discipline; equivalent demonstrable experience will also be considered.
• Substantial professional software development experience, typically eight or more years, including ownership of production applications.
• Demonstrated experience in a senior development, technical lead, software architect or comparable role.
• Proven experience designing and delivering full stack applications from requirements through deployment and operational support.
• Practical experience with Linux, databases, cloud infrastructure and production troubleshooting.
• Experience guiding developers, reviewing technical work and making architectural decisions.
• Relevant cloud, networking or Linux certifications would be advantageous

Required Technical Competencies

• Software Engineering & Architecture: Strong back‑end skills in Java and/or languages like Python, PHP, TypeScript, or C#; proficiency in JavaScript/TypeScript, HTML, CSS, and modern front‑end frameworks.
• Core Principles: Expertise in object-oriented design, SOLID principles, modular architecture, REST APIs, asynchronous processing, and secure development (authentication/authorization).
• Databases & Data Processing: Strong SQL skills and relational database experience (MySQL, MariaDB, PostgreSQL) covering indexing, transactions, optimisation, and migrations, plus familiarity with NoSQL, caching, and messaging.
• Infrastructure & DevOps: Solid Linux administration, cloud experience (preferably AWS), Git, CI/CD pipelines, Docker deployments, networking (TCP/IP, DNS, firewalls, VPNs), and system monitoring/backups.

Advantageous Experience

• Industrial IoT, telemetry, smart metering, utilities, renewable energy, MQTT, or event‑driven systems managing fleets of intermittent devices.
• MongoDB, Redis, message brokers, event‑streaming, IaC, hybrid/hosted infrastructure, Android development, and embedded hardware collaboration.
• Operational analytics, anomaly detection, or practical AI integration.

Personal Attributes

• Takes full ownership, combines architectural judgement with hands‑on coding, and balances technical quality with practical delivery.
• Systematic problem solver, independent worker, and effective cross‑functional collaborator.
• Communicates clearly and maintains a customer‑focused approach to reliability and service delivery

Duties will include, but not limited to:

Software and systems architecture

• Lead the architecture and technical design of new software platforms and enhancements to existing systems.
• Translate business objectives, customer requirements and operational constraints into practical technical solutions.
• Define application structures, service boundaries, data models, APIs and integration approaches.
• Design for security, maintainability, scalability, performance, availability and interoperability.
• Assess existing applications and infrastructure, identify technical debt and develop prioritised improvement roadmaps.
• Evaluate technologies and frameworks, considering lifecycle cost, team capability and long‑term supportability.
• Maintain architectural documentation and provide technical authority for design decisions and reviews.

Full stack software development

• Lead and contribute directly to developing, maintaining and improving back‑end services, web applications and operational tools.
• Develop business logic, APIs, dashboards, reporting functions and customer workflows.

• Develop device‑management, alerting, incident‑management and diagnostic capabilities.
• Support integration with metering, utility and industrial systems.
• Work with hardware and firmware engineers to define interfaces, communication behaviour and diagnostic requirements.
• Establish data foundations for reporting, analytics and appropriate AI or machine‑learning applications.

Development planning and delivery

• Work with management, engineering teams and customers to define scope, priorities and acceptance criteria.
• Prepare technical specifications, development estimates and implementation plans.
• Identify technical risks, dependencies and resource requirements.
• Break complex projects into achievable development stages and communicate progress clearly.
• Support technical proposals, feasibility assessments and customer demonstrations.
• Take responsibility for technical delivery against agreed requirements and quality expectations.

Software quality, DevOps and deployment
