SENIOR .NET BACK-END DEVELOPER

.NET / JAVA

WHO PLATFORM45 IS

We are responsible for code changing the lives of people around the world, every day. We solve complex problems and build big ideas. We believe in the ability of technology to make the world a better place; we’re driven to rip through conformity and create new solutions, and smarter habits. We know why we’re here: To unleash the potential of people through the power of technology. We are people multiplied by the power of tech and together we are changing the world.

CONTEXT | THE ROLE

As a Senior Back-End Developer, you will lead the development of complex software solutions, collaborate with cross-functional teams, and drive technical excellence within our organisation. You’ll be embedded on a strategic engagement with an enterprise financial-services client that is migrating its platform to AWS cloud services - an exciting opportunity to work on challenging, high-impact projects, contribute to the success of our clients, and shape the future of not only our business but theirs.

ROLE RESPONSIBILITIES | THE WHAT & THE HOW

The Essentials

Software Development

Lead the design, development, and implementation of scalable, robust back-end systems and APIs that meet client requirements and industry standards.

Technical Leadership

Provide technical expertise and guidance to development teams, ensuring adherence to best practices, coding standards, and architectural principles.

Solution Architecture

Collaborate with stakeholders to define system architecture, identify technical requirements, and design innovative solutions that address complex business challenges. Architect and implement microservices and distributed systems that ensure high availability and performance. Contribute to the migration of services and workloads to AWS, ensuring reliability, security, and performance throughout the transition.

Code Review and Quality Assurance

Conduct code reviews, perform thorough testing, and implement quality assurance processes to ensure the reliability, performance, and security of software applications.

Requirement Analysis

Work closely with clients to understand their needs, gather requirements, and propose technical solutions that align with their objectives and budget constraints.

Continuous Improvement

Stay updated on emerging technologies, industry trends, and best practices in software development, and leverage this knowledge to enhance our development processes and capabilities.

Mentoring

Provide mentorship to junior / less-experienced engineers, helping them grow their technical expertise and guiding them on best practices, coding standards, and architectural principles.

Documentation

Strong documentation practices that prioritise practical value over exhaustive detail are essential: maintaining clear, purposeful documentation focused on architectural decisions, system boundaries, and integration points that future team members will actually need, while avoiding docs that quickly become outdated or remain unread.

TECHNICAL REQUIREMENTS

• Bachelor’s degree in Computer Science, Engineering, or a related field, or provable, self-taught development skills with a good understanding of how the web works.
• 5 – 7+ years of experience in back-end software development, with strong proficiency in .NET (C#) and/or Java and their associated server-side frameworks and tooling. Proficiency with Ruby on Rails, or React/similar front-end frameworks and meta-frameworks would be an advantage.
• Experience with databases (SQL and NoSQL), such as PostgreSQL, MySQL, or MongoDB, and an understanding of data modelling.
• Strong knowledge of RESTful APIs, microservices architecture, and asynchronous programming.
• Hands-on experience with Microsoft Azure, particularly Azure App Services.
• Strong, demonstrable experience with AWS is essential. The client’s platform is undergoing a strategic migration to AWS cloud services, so you should be comfortable designing, deploying, and operating workloads on AWS. Experience migrating workloads from Azure to AWS is a significant advantage.
• Familiarity with containerization technologies (Docker, Kubernetes).
• Understanding of security best practices and performance optimisation techniques.
• Strong proficiency in modern testing practices including unit testing, end-to-end testing, and the ability to establish robust testing strategies.
• Advanced Git workflow management and experience implementing version control and CI best practices.
• Proven track record of successfully delivering complex software projects from conception to deployment.
• Deep understanding of software architecture, design patterns, and development methodologies.
• Excellent problem-solving skills and the ability to troubleshoot technical issues effectively.
• Experience working in Agile environments and familiarity with Agile practices and tools (e.g., Scrum, Kanban, JIRA).
• Strong communication and interpersonal skills, with the ability to collaborate with cross-functional teams and communicate technical concepts to non-technical stakeholders.
• Commitment to continuous learning and professional development.

CRITICAL COMPETENCIES

• You have an entrepreneurial mindset and can understand the business value of a project.
• You have the ability to research and develop new products and modifications to existing software when needed.
• You are someone who is motivated, energetic, and always focused on the task at hand.
• A strategic thinker who can work under pressure, independently problem-solve, and draw knowledge from a broad range of experiences.
• A proactive, continuous, and quick learner who is genuinely excited about industry trends and has a passion for technology and knowledge.
• A resourceful, ‘big-picture’ thinker who considers how the code that is written will have an impact later on.
• Good communication and teamwork are critical - you’ll be dealing not only with developers but also designers, product owners, clients, and other key stakeholders.
• Play a mentorship role to our interns, juniors, and other less-experienced engineers.
