Job description

Type of employment : Permanent or Contract

• 12+ years of hands-on full stack development of enterprise-grade applications, across front-end, back-end and data layers.
• Strong command of modern languages, frameworks, microservices, REST/event-driven APIs and cloud-native architecture.
• Proven ability to define and own an architecture vision, set patterns, standards and drive them through delivery.
• Deep expertise in enterprise security, data privacy and adherence to multiple organisational and regulatory policies.
• Experience engineering for business continuity, resilience, high availability and disaster recovery (BCM).
• Excellent communication and stakeholder-management skills across technical and business teams.
• Hands-on experience with spec-driven development frameworks (e.g GitHub Spec-Kit) for writing specifications, plans and tasks that drive code generation.
• Practical experience with intent-based development, translating high-level intent into working, testable software rather than manual line-by-line coding.
• Proficiency with AI pair-programming assistants such as GitHub Copilot paired with Claude Code for large-scale, production-grade code generation and refactoring.
• Working experience with agentic AI IDEs / cloud coding agents (e.g., AWS Kiro) for spec-to-code and autonomous task execution.
• Ability to reverse-engineer and re-platform legacy applications from limited vendor documentation, strategy/configuration files and tacit process knowledge.
• Skilled at structuring SME knowledge-elicitation by defining a repeatable approach to convert undocumented process knowledge into precise, AI-consumable specifications and developer-ready requirements.
• Ability to take initiative and lead technically along with people management skills without being implicitly authoritative and to orchestrate interfacing with external databases, systems and cross-functional teams.

Behavioural / Soft Skills

• Self-starter who brings structure to ambiguous, evolving programmes.
• Collaborative, consultative style & comfortable guiding SMEs and peers alike.
• Ability to simplify and communicate technical aspects with a delivery and outcome-first mindset.
