Senior Software Engineering Lead

The Senior Software Engineering Lead plays a critical role in contributing to high-performing teams, ensuring the Telstra network delivers a superior network experience for consumer and business customers.

The role combines extensive domain expertise and technical capabilities to influence the team to deliver a great customer experience.

Job Description

• Lead end-to-end solution architecture and design, taking solutions from discovery and requirements through detailed design, build, testing, production deployment, and transition.
• Define solution architectures, integration patterns, technology options, and Key Design Decisions, supported by clear architecture documentation and diagrams.
• Design API-first, microservices, and event-driven solutions across network and OSS/BSS environments, including ingress and egress APIs, asynchronous messaging, and integration contracts.
• Work closely with TPOs, Mission Leads, Engineering Leads, delivery squads, Security teams, and other stakeholders to translate business and technical requirements into practical solution designs.
• Facilitate architecture and design reviews, communicate architectural decisions and trade-offs, and resolve technical dependencies across upstream and downstream systems and delivery teams.
• Review functional and non-functional requirements, ensuring scalability, reliability, resilience, observability, security, data protection, and operational supportability are built into solution designs.
• Lead security endorsement and architecture governance activities, working with security architects and risk teams to address authentication, authorisation, encryption, compliance, and data protection requirements.
• Support engineering teams throughout implementation by reviewing technical designs, interfaces, and stories, clarifying architectural intent, and ensuring delivery remains aligned with the agreed architecture.
• Manage architectural risks, dependencies, and technical constraints throughout delivery, including coordinating between engineering, security, delivery, and stakeholder groups.
• Support production readiness and transition planning, using phased implementation approaches where required to enable safe and effective production delivery.
• Lead architecture for legacy transformation, simplification, modernisation, and cloud migration, identifying opportunities to move towards sustainable future-state architectures.
• Evaluate emerging technologies and alternative design approaches, recommending solutions aligned with strategic architecture direction and long-term platform objectives.

Skills & Experience

• 5+ years' experience working as an End-to-End Solution Designer, Solution Architect, or equivalent technical architecture role.
• Strong knowledge of fixed-line, wireless, and satellite services, including network elements, alarms, and alerts.
• Demonstrated experience designing solutions across network, OSS, and BSS environments.
• Strong experience in data and service modelling, API design, integration design, and ETL, including defining interfaces and integration contracts between platforms.
• Proven experience designing microservices, event-driven architectures, asynchronous messaging, and distributed systems.
• Experience in legacy transformation and cloud migration, with AWS experience highly desirable.
• Strong understanding of security architecture and encryption standards, including authentication, authorisation, compliance, and data protection considerations.
• Strong understanding of non-functional requirements, particularly reliability, resilience, scalability, observability, and operational supportability.
• Experience managing architectural dependencies and assessing solution impacts across upstream and downstream systems.
• Ability to translate complex business and technical requirements into clear, pragmatic, and implementable solution architectures.
• Strong stakeholder engagement and communication skills, with the ability to explain architectural decisions, risks, and trade-offs to both technical and non-technical stakeholders.
• Experience working collaboratively with engineering, architecture, security, risk, product, and delivery teams throughout the solution lifecycle.
• Experience supporting engineering teams through implementation, production readiness, and transition to production.
• Experience evaluating technology options and identifying opportunities for modernisation, simplification, and future-state architecture.
• Experience delivering solutions across Agile/Scrum and Waterfall environments.
