Job description

Together, We Can Make A Significant Impact – Position Overview

As a Senior Software Engineer, you will be part of an Agile, cross‑functional product delivery team responsible for designing, developing, testing, and maintaining mission‑critical digital solutions. You will deliver the full scope of Software Engineer responsibilities while taking on greater ownership in technical design, code quality, testing strategy, estimation, delivery risk management, and technical guidance for assigned modules or workstreams.

Working under the guidance of the Solution Architect and Software Architects, you will analyse existing software codes and processes, recommend scalable and secure software solutions, and collaborate with the Engineering Team and HTX work units to make informed decisions on tools, technologies, and design patterns. This role is suitable for engineers with a minimum of 4 years of relevant software development experience who are ready to contribute as a technical lead within an Agile delivery environment.

Key Responsibilities

Core Software Engineering

• Deliver functional, tested, secure, and scalable software features based on the product backlog, agreed sprint priorities, and project delivery plans.
• Work in cross‑functional Agile teams and contribute to sprint planning, backlog refinement, development, reviews, retrospectives, and continuous improvement.
• Collaborate with QA engineers, Product Designers, DevOps engineers, Business Analysts, Product Owners, Product Managers, and stakeholders to ensure solutions meet both technical and user requirements.
• Clarify requirements where required and translate business or user needs into technical specifications, implementation tasks, and acceptance considerations.
• Design and develop front‑end applications, backend services, APIs, and software modules using the project’s approved technology stack.
• Support software development for Proof of Concept (POC) and/or Initial Operations Capability (IOC) initiatives, enabling safe experimentation and incremental delivery.
• Write, maintain, and guide the implementation of unit, integration, and end‑to‑end tests to support automated testing, quality gates, and continuous integration pipelines.
• Design, implement, and maintain CI/CD pipeline templates for automated build, testing, security scanning, and deployment in alignment with the Authority’s toolchain.
• Set up, maintain, and troubleshoot development environments to support productive development, testing, experimentation, and onboarding of engineers.
• Apply DevSecOps practices, Infrastructure as Code (IaC) principles, secure coding standards, and software maintenance best practices where applicable.
• Investigate, troubleshoot, and resolve software defects, technical issues, and post‑deployment support matters in a timely manner.

Software Leadership and Technical Ownership

• Lead software teams, modules, projects, or workstreams, ensuring that engineering delivery is well planned, coordinated, and aligned to sprint and release objectives.
• Analyse existing software codebases and processes, identify improvement areas, and provide technical recommendations for scalable, secure, and maintainable software solutions under the guidance of the Solution Architect and Software Architects.
• Collaborate closely with the Engineering Team and HTX work units to make informed decisions on tools, technologies, architecture implementation, and design patterns to address complex problems.
• Lead technical design discussions, implementation planning, technical evaluation, benchmarking, and solution trade‑off assessments.
• Oversee code quality through regular code reviews, ensuring adherence to coding standards, secure coding practices, design principles, documentation expectations, and engineering best practices.
• Establish and uphold testing strategies, including unit, integration, end‑to‑end, performance, and reliability testing approaches, to improve software quality and reduce delivery risk.
• Collaborate with Product Managers, Product Owners, Business Analysts, and Designers to define, refine, and implement software requirements that are technically feasible and aligned with user needs.
• Work with Product Managers and delivery stakeholders to estimate timelines, resources, dependencies, and technical risks, and support timely delivery of software projects.
• Provide technical leadership, coaching, and mentorship to engineers, including reviewing technical approaches, unblocking issues, and raising engineering capability across the team.
• Promote continuous improvement in development practices, team collaboration, quality assurance, DevSecOps adoption, and software maintainability.
• Escalate technical risks, delivery blockers, and design concerns early, with practical options and recommendations for resolution.

Job Requirements

• Degree in Information Technology, Computer Science, Software Engineering, or a related discipline, with at least 6 years of hands‑on software development experience and a minimum of 3 years leading software teams, modules, workstreams, or projects.
• Professional experience and demonstrated skills in Software Architecture, Systems Design, or related areas may be considered in lieu of formal education.
• Proven experience leading a technical team or software project in Agile/Scrum environments, including planning, coordination, technical guidance, and delivery follow‑through.
• Strong proficiency in one or more relevant languages or frameworks, such as TypeScript with Angular, React, or Next.js; C#; Java; or other languages depending on project needs.
• Experience with one or more database technologies, such as MSSQL, PostgreSQL, or Oracle.
• Strong understanding of SDLC practices, object‑oriented programming, RESTful API design, microservices architecture, software maintenance, secure coding practices, and DevOps principles.
• Hands‑on experience with CI/CD pipelines, automated testing, code quality practices, version control tools such as Git and GitHub or equivalent platforms, and collaboration tools used in Agile delivery.
• Knowledge of containerisation and orchestration technologies such as Docker and Kubernetes. Exposure to cloud environments, Infrastructure as Code, and DevSecOps toolchains will be advantageous.
• Ability to establish and uphold testing approaches across unit, integration, end‑to‑end, performance, and reliability testing to improve software quality and delivery confidence.
• Ability to apply industry best practices in quality assurance, technical evaluation, benchmarking, and software delivery, and adapt approaches based on project requirements.
• Excellent analytical and problem‑solving skills, with the ability to investigate complex issues, evaluate options, and propose practical technical solutions.
• Strong leadership, communication, and interpersonal skills to effectively manage and mentor engineers, collaborate with cross‑functional teams, and engage stakeholders.
• Responsible, adaptable, and comfortable working in a mission‑driven environment where quality, security, reliability, maintainability, and impact matter.

What We Offer

• Opportunity to work on meaningful public sector digital initiatives.
• A supportive, purpose‑driven team culture.
• Structured career development and technical upskilling.
• Access to modern tools, cloud technologies, and secure DevSecOps environments.
