Job Description

Our client is looking for a Senior API Developer who thrives on writing great code and delivering solutions that make a measurable impact. This is a hands-on development role — you’ll spend most of your time designing, coding, and optimizing APIs that drive essential business systems.

The ideal candidate is an experienced engineer with deep technical expertise in C#, Azure Functions, Logic Apps, and GitHub, and who takes pride in crafting clean, scalable, and secure solutions. You think about performance and security from the start, test thoroughly, and collaborate effectively across teams. You move quickly but never at the expense of long-term quality.

If you’re a senior-level developer who loves building elegant, high-performance APIs and enjoys working closely with a team of professionals to deliver real value — we’d love to hear from you.

What You’ll Do

• Design, develop, test, and deploy high-quality APIs in C# and .NET Core to support core business applications and integrations.
• Collaborate with product owners, UI engineers, database specialists, and QA to deliver cohesive, end-to-end solutions.
• Build serverless workflows using Azure Functions and Logic Apps for automation and event-driven processes.
• Implement best practices for API performance, scalability, and security, including OAuth, JWT, and API Gateway policies.
• Write clean, testable, and maintainable code, proactively addressing quality issues before they reach QA.
• Monitor, debug, and optimize API performance using Azure Application Insights and Log Analytics.
• Set up and maintain CI/CD pipelines in GitHub Actions to automate builds, testing, and deployments.
• Manage and secure APIs through Azure API Management (APIM), ensuring efficient governance and monitoring.
• Participate in code reviews, mentorship, and knowledge sharing to strengthen team capabilities.
• Continuously explore new technologies and approaches to improve processes and system performance.

What You’ll Bring

• Bachelor’s degree in Computer Science, Engineering, or equivalent practical experience.
• 6+ years of experience developing APIs using C# and .NET Core.
• Strong hands-on experience with Azure Functions and Logic Apps.
• Expertise in Azure API Management (APIM).
• Solid understanding of RESTful API design, authentication standards (OAuth, JWT), and security best practices.
• Experience implementing CI/CD pipelines, preferably with GitHub Actions.
• Knowledge of SQL/NoSQL databases and integration design patterns.
• Skilled in logging, monitoring, and debugging with Azure tools.
• Proven track record of delivering high-quality, scalable code in an Agile team environment.
• Excellent communication and teamwork skills, with the ability to collaborate across technical and business teams.
• Experience with GraphQL or gRPC is a plus.

Bonus Skills

• Familiarity with message queues such as Azure Service Bus or Event Grid.
• Experience with Docker, Kubernetes, and microservices architecture.
• Knowledge of Infrastructure as Code tools like Terraform or Bicep.
• Experience using Jira and Confluence for project collaboration.
