Senior Developer

The Senior Developer will be responsible for designing, developing and maintaining backend services using .NET Core / ASP.NET Core on AWS, with a strong focus on serverless architectures and event-driven systems using Kafka / AWS MSK. The Senior Developer will also work with containerised workloads on Kubernetes, and have exposure to modern DevOps and CI/CD practices.

The Senior Developer will be part of an agile product team, collaborating closely with product owners, business analysts, engineers, architects, QAs and DevOps to deliver secure, performant and reliable solutions.

Key Responsibilities

• Design, build and maintain backend services and APIs using .NET Core / ASP.NET Core.
• Develop modern web UIs (React / Angular / TypeScript or similar) and integrate them with backend services.
• Develop and support AWS serverless solutions (e.g. Lambda, API Gateway, Step Functions, DynamoDB, S3).
• Implement event-driven architectures using Kafka (preferably on AWS MSK) for high-throughput, near real-time processing.
• Work with Docker and Kubernetes to build, deploy and run containerised services.
• Contribute to the design and implementation of scalable, secure and resilient cloud architectures.
• Work with DevOps engineers to enhance CI/CD pipelines, automated testing and deployment processes.
• Model and optimise data across SQL and NoSQL stores.
• Drive code quality: write clean, efficient, well-documented and reusable code.
• Participate in code reviews, technical discussions and agile ceremonies.
• Troubleshoot production issues and improve monitoring, logging and alerting across services.
• Collaborate with stakeholders to refine requirements and deliver high-quality solutions on time.
• Build positive relationships with rest of development teams.
• Strong communication, and interpersonal skills.

Skills and Experience required

• Strong commercial experience with .NET Core / ASP.NET Core for backend development.
• Proven experience building solutions on AWS, ideally including serverless services (Lambda, API Gateway, DynamoDB, etc.).
• Hands-on experience with Kafka (preferably AWS MSK) for messaging/stream processing.
• Experience with Docker and Kubernetes for container orchestration.
• Good understanding of DevOps concepts, with practical experience using Git and working with CI/CD tooling (e.g. GitHub Actions, Azure DevOps, GitLab CI or similar).
• Experience with both SQL (e.g. SQL Server, PostgreSQL, MySQL) and NoSQL databases (e.g. DynamoDB, MongoDB).
• Exposure to Big Data tools/platforms and data pipelines (streaming and/or batch) is strongly preferred.
• Comfortable working in an agile environment (Scrum/Kanban).
• Strong problem-solving skills, attention to detail and a collaborative mindset.
• Ability to take ownership, solve complex problems and mentor more junior engineers where required.

Nice to have

• Experience delivering systems on GCP.
• Knowledge of microservices and event-driven architectures.
• Experience with Infrastructure as Code (e.g. CloudFormation, CDK, Terraform).
• Any experience with MCP (Model Context Protocol) and/or MLOps (e.g. model deployment pipelines, monitoring and lifecycle management) is highly desirable.
• Understanding of compliance requirement around SDLC, ITGC,ITAC

The Senior Developer will demonstrate strong collaboration skillset with the rest of the development team, as well as producing high-quality code and showing initiative by identifying solutions to increase productivity.
