Core Responsibilities

Primary Functions

Lead the design, architecture, development and deployment of complex software applications from concept through production, ensuring scalability, reliability and maintainability.
Translate business and product requirements into coherent technical specifications and actionable development tasks, driving the full software lifecycle.
Mentor, coach and guide other software engineers on the team — supporting skill development, promoting best practices and performing code reviews.
Define, enforce and evolve software development standards, coding guidelines, automated testing frameworks, CI/CD pipelines and release processes.
Collaborate closely with cross‑functional teams (product management, UX/UI, QA, DevOps, infrastructure) to align software deliverables with business objectives.
Lead architecture discussions, technology evaluations, and make strategic decisions on frameworks, languages, libraries and infrastructure.
Monitor, measure and optimise application performance, identify bottlenecks, implement caching, concurrency, asynchronous processing and distributed systems design.
Ensure robust application security, authentication/authorization, encryption, data protection and compliance to relevant regulatory standards.
Drive initiative to refactor legacy systems and reduce technical debt, balancing feature delivery with long‑term sustainability and code quality.
Manage software release planning including version control, branching strategies, release documentation, rollback procedures and post‑release support.
Conduct risk assessments, define mitigation plans for software projects, escalate issues and ensure the team meets delivery commitments on time and within budget.
Provide visibility of progress, impediments and technical risks to senior leadership and stakeholders; produce project reports, deliverables and status updates.
Participate in and lead agile development ceremonies (sprint planning, stand‑ups, reviews, retrospectives), estimate development tasks and prioritise backlog items.
Work hands‑on alongside your team, contributing to development tasks, debugging production issues, performing root‑cause analysis and guiding operational support.
Define and maintain technical documentation including architecture diagrams, interface definitions, data models, run‑books and onboarding guides.
Evaluate new tools, frameworks, development methodologies and champion continuous improvement across processes, codebase and team productivity.
Lead recruitment, hiring and onboarding of software engineering talent; help build the technical culture and growth path within the team.
Oversee integration of software applications with cloud infrastructure, containerisation (Docker/Kubernetes), microservices, REST and/or event‑driven architectures.
Support the operations and monitoring of software services post‑deployment, ensure high availability, incident response, root‑cause analysis and post‑mortems.
Act as a technical liaison between engineering and business stakeholders, translating complex engineering ideas into business‑friendly language and vice versa.

Secondary Functions

Support ad‑hoc data requests and exploratory data analysis.
Contribute to the organisation’s data strategy and roadmap.
Collaborate with business units to translate data needs into engineering requirements.
Participate in sprint planning and agile ceremonies within the data engineering team.

Required Skills & Competencies

Hard Skills (Technical)

Proficiency in one or more major programming languages (e.g., Java, C#, Python, JavaScript/TypeScript) and deep experience building full‑stack software.
Solid understanding of software architecture, design patterns, distributed systems, microservices, event‑driven architecture and web services (REST, GraphQL).
Experience with relational and/or NoSQL databases, data modelling, performance tuning and query optimisation.
Hands‑on experience with containerisation (Docker), orchestration (Kubernetes), cloud platforms (AWS, Azure, GCP) and CI/CD pipelines (Jenkins, GitLab, GitHub Actions).
Strong track record of leading code reviews, establishing coding standards, automated unit/integration testing, TDD/BDD practices and continuous deployment.
Experience in application performance monitoring, logging, tracing tools and techniques for production systems.
Knowledge of security principles, authentication/authorization mechanisms (OAuth2, JWT), encryption, data protection and regulatory compliance.
Understanding of front‑end technologies/frameworks (React, Angular, Vue) or at least ability to collaborate across full‑stack developers.
Strong ability to translate business requirements into technical solutions and deliver enterprise‑grade software.
Familiarity with Agile/Scrum methodologies, backlog management, sprint ceremonies, estimation techniques and team planning.
