Senior Fullstack Developer (.NET)

Our Why
Datacom works with organisations and communities across Australia and New Zealand to make a difference in people’s lives and help organisations use the power of tech to innovate and grow. 

About the Role (your why)

We are seeking a versatile and highly skilled Senior Fullstack Developer with a strong generalist mindset to join our engineering team. In this role, you won't just write code; you will design, build, and maintain robust, end-to-end applications and integration solutions. As a generalist, you thrive on solving complex engineering problems across the entire stack—from crafting intuitive user experiences to architecting scalable backend systems. You are highly adaptable, cloud-agnostic, and passionate about seamless system integrations and modern software engineering principles.

Key Responsibilities

• End-to-End Application Development: Design, develop, and deploy scalable, high-performance web applications, managing the full software development lifecycle from concept to production.
• Modern Frontend Development: Build responsive, highly interactive user interfaces primarily utilizing React, ensuring a focus on clean architecture, state management, and optimal user experience.
• Robust Backend & Integration Architecture: Architect and implement secure, scalable backend services and APIs using the .NET stack (C#). Design integration solutions that connect internal systems, microservices, and third-party APIs seamlessly.
• Cloud-Agnostic Deployment: Deploy and maintain applications across various cloud ecosystems (e.g., AWS, Azure) utilizing infrastructure-as-code principles and modern CI/CD pipelines.
• Data Layer Management: Design, optimize, and manage both relational (e.g., SQL Server, PostgreSQL) and non-relational databases, leveraging ORMs like Entity Framework while maintaining the ability to write raw, high-performance queries.
• Quality & Automation: Write comprehensive unit, integration, and end-to-end tests. Champion automated testing strategies to ensure application stability and continuous delivery.
• Technical Leadership & Collaboration: Actively participate in design reviews and code reviews. Mentoring and fostering a culture of technical excellence and shared learning.
• Agile Delivery: Partner with product managers and stakeholders to break down complex business requirements into clear technical specifications within an Agile framework.

Key Skills & Qualifications

Technical Core

• Backend Expertise: Strong proficiency in modern .NET (.NET Core / .NET 6+) and C#, with deep experience building Web APIs, RESTful services, and microservices.
• Frontend Expertise: Solid experience with modern React (including hooks, state management, and modern build tools) alongside a strong foundation in TypeScript/JavaScript, HTML5, and CSS3.
• Integration & Systems Design: Proven experience designing and integrating complex APIs, webhooks, event-driven architectures, and third-party services.
• Cloud & DevOps: A cloud-agnostic mindset with experience deploying to platforms like AWS or Azure. Familiarity with Docker, containerization, and building automated CI/CD pipelines.
• Database Proficiency: Strong skills in database design, query optimization, and data modelling (SQL and NoSQL options).

Soft Skills

• Generalist Aptitude: A strong ability to quickly pick up new technologies, frameworks, or languages as required by the business problem.
• Problem Solving: Exceptional analytical and debugging skills across distributed systems.
• Collaboration: Excellent communication skills with the ability to articulate technical concepts to both technical and non-technical stakeholders.
• Leadership: Proven track record of mentoring team members and driving software engineering best practices (Clean Code, SOLID principles, TDD).
