Backend Software Engineering

Remote, Remote

Connectivity Credits is moving from MVP and pilots to a production-grade platform that supports multiple countries, internet providers, measurement systems and funding models. We're looking for a backend engineer to add dedicated capacity for that move.

You will:

• Design, build, test and deploy backend services and APIs in Python (TypeScript also used)
• Build event-driven workflows and rules, e.g. turning measured connectivity performance into credits
• Integrate with measurement systems, partners and other platforms
• Own software quality: automated tests, CI/CD, deployment and operations
• Apply secure development practices
• Document your work and collaborate closely with the product and tech team, who set the architecture

Most of the work is greenfield, with existing MVPs and prototypes as a starting point. You'll work independently once direction is agreed.

This is a 6-month consultancy (contract), fully remote. Apply by 12 November 2026 via UNICEF's careers site with a CV, a cover letter (max 2 pages) and a financial proposal (template on the posting).

Required:

• 3+ years of professional software development, mostly hands-on backend
• Backend services and APIs in Python and/or TypeScript
• Distributed or service-oriented systems: async processing, retries, idempotency, failure handling
• REST APIs, JSON integrations and relational data modelling
• Containers, CI/CD and automated testing
• Secure development: authentication, authorization, input validation, secrets management, least privilege
• Bachelor's degree in computer science, software engineering, IT or a related field
• Fluent English (another UN language is a plus)

Nice to have:

• Apache Kafka or other event streaming platforms
• Rule engines or workflow engines
• Java
• Blockchain / Web3 systems
