We are looking for a Senior Full-Stack Developer who thrives at the intersection of technical design and hands-on execution. In this role, you will be the technical engine driving key initiatives for integration projects. Unlike a traditional architect role, your focus will be on Solution Design: creating the technical 'how-to' for complex integrations and then leading the end-to-end development.

Main Responsibilities:

• Draft end-to-end technical designs for API solutions and microservice integration patterns.

• Own the full development cycle, ensuring secure, low-latency communication paths between backend systems and UI/UX layers.

• Manage the technical integration of platforms using Azure Functions and Service Bus.

• Fine-tune Python-based code while having the agility to refactor logic as needed.

• Participate in design reviews and incorporate stakeholder feedback.

• Support discussions surrounding potential migrations to managed environments.

Key Requirements:

• 7+ years of hands-on experience in Azure development (Functions, App Insights, APIM, and Service Bus).

• Expertise in Python, with strong proficiency in Java or .NET.

• A 'quality-first' mindset with extensive experience writing and maintaining unit tests.

• Deep expertise in using Application Insights for monitoring and optimizing live applications.

• Proven experience in designing and building integration patterns within a CRM context.

Nice to Have:

• Experience with Google Cloud Platform (GCP).

• Prior experience with Highspot, Pendo, or MS Dynamics integrations.

Other Details:

This position will involve working on integration projects, with potential opportunities for remote collaboration. The role emphasizes hands-on development and strategic planning for future migrations.
