Role summary

We're looking for a hands-on Senior Backend Developer / Technical Lead (Python) to drive the technical execution of an enterprise integration solution built on top of the VMIA framework and Azure cloud. This role sits at the core of a system-to-system integration initiative for an international client — you'll design and build serverless backend components that move data reliably between Salesforce and surrounding systems, own the CI/CD pipelines that ship them, and use AI-assisted tooling to accelerate delivery without cutting corners on quality.

Responsibilities

• Design, build, and scale Azure Functions and lightweight integration microservices, including background workers that handle large file attachment streaming (>10MB) and asynchronous payload processing.

• Implement webhook listeners for Vault Spark notifications and outbound REST clients for write-backs to Salesforce.

• Own REST API and integration architecture -JSON processing, asynchronous communication patterns, and system-to-system data transformation pipelines.

• Configure and maintain automated CI/CD pipelines in GitHub (GitHub Actions / Workflows) to build and deploy containerized/serverless components into client-owned Azure environments.

• Actively use GitHub Copilot and AI coding assistants to accelerate development, boost unit test coverage, and streamline documentation.

• Contribute to architectural decisions and technology stack choices as part of a small, senior technical team.

Requirements

Must-have:

• Strong hands-on experience with Azure Functions and serverless/microservices architecture

• Advanced proficiency in REST APIs, webhooks, JSON processing, and asynchronous communication patterns

• Practical experience setting up CI/CD pipelines in GitHub (GitHub Actions / Workflows)

• Familiarity with GitHub Copilot or similar AI coding assistants in daily development work

• Solid programming skills in Python, React.js, and TypeScript

• Fluent English, both written and spoken

Nice-to-have:

• Experience integrating with Salesforce (REST write-backs, event-driven patterns)

• Experience with enterprise document/attachment streaming and large-payload processing

• Familiarity with Veeva Vault or similar validated/regulated system landscapes

• Understanding of Infrastructure as Code (Terraform, ARM Templates)

We offer:

• B2B contract (rate negotiated individually, up to 220 PLN net/h + VAT)

• Fully remote service delivery

• Broad range of projects (internal, international) - genuine variety of clients and tasks

• Budget for skills development and certifications as part of the collaboration

• Regular collaboration reviews and discussion of project scope

• Additional benefits available as part of the collaboration

• Networking and team-building events for project teams
