We are looking for a Senior Software 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 mainly for specific transformations (e.g. Pendo-related) 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).

• Strong experience in .NET development (primary technology.)

• Experience in building integration solutions using .NET and Azure.

• Expertise in Python (basic/working knowledge required, mainly for integration/transformation tasks), with strong proficiency in .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:

• Exposure to Power Platform (optional).

• Experience with Google Cloud Platform (GCP).

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