Backend Software Engineering

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
