Job Description

Join Our Dynamic Team as a Developer! 🌟

Are you passionate about telecoms? Do you thrive in a fast-paced, innovative environment? At Babble, we’re on a mission to be our customer’s most trusted advisor for cloud-based technologies. We’re looking for passionate and talented individuals to join our dynamic team. If so, we have the perfect opportunity for you!

What will you be doing?

The purpose of this role is to design, build, and maintain custom software solutions that extend the functionality of our platform and connect it with the systems of our partners, customers, and third-party services, ensuring reliable and secure data exchange throughout. The primary focus of the role is on extending existing functionality and building integrations, with the Developer also designing and delivering full standalone solutions for customers, and occasionally for internal use, as requirements demand.

The Developer will design and implement solutions end to end, resolve issues in development and production, and contribute to a resilient, observable and maintainable technology platform. The Developer is accountable for delivering custom solutions from initial design and implementation through to secure, reliable operation in production, whether that solution extends an existing system, integrates it with another, or stands alone. The role sits at the intersection of software development and solution architecture, works closely with internal teams and external customers to understand requirements and define data contracts, upholds engineering standards through code reviews and clear documentation, and, as opportunities arise, cross-skills into other development projects across the business.

Main Accountabilities

The role holder will be directly accountable for delivering the following technical and delivery objectives, with measurable outcomes aligned to agreed engineering standards, security requirements, and solution reliability, maintaining a hands-on approach when required:

Solution & Integration Design and Development

Design, develop, and maintain custom solutions using .NET (C#, .NET Core / .NET 6+), primarily by extending existing platform functionality and building integrations between internal and external systems.
Build and consume RESTful APIs, alongside other interfaces such as SOAP, GraphQL, or messaging/event-based integrations where relevant; version, publish and maintain APIs to consistent standards.
Design and build full standalone solutions for customers, and occasionally for internal use, where requirements go beyond extending or integrating existing systems, taking a solution from requirements through to delivery.

Security & Authentication

Implement secure authentication and authorisation across the solutions and integrations you build, applying the appropriate methods (e.g., OAuth 2.0, OpenID Connect, JWT, API keys, mutual TLS) for each scenario.

Monitoring, Troubleshooting & Reliability

Troubleshoot solution and integration failures, data mismatches, and performance issues across development and production environments, debugging across system and application boundaries to isolate root causes.
Monitor solutions and integrations in production and contribute to logging, alerting, and observability practices to support prompt detection and resolution of issues.

Documentation, Collaboration & Engineering Standards

Write clear technical documentation for the solutions, APIs, and integrations you build, ensuring they are usable by both internal teams and external consumers.
Collaborate with internal teams and external customers to understand requirements, define data contracts and integration specifications, and translate them into technical designs, setting expectations and communicating progress throughout delivery.
Participate in code reviews and help uphold engineering standards across the team, contributing to CI/CD practices and Git-based workflows.

The Employer reserves the right to amend the employee's job title or description to meet its business needs subject to giving the employee reasonable notice.

Qualifications

Solid commercial experience developing in .NET (C#, .NET Core / .NET 6+), able to work independently on a feature or solution as well as part of a team.
Strong familiarity with API development, including designing, building, versioning, and consuming RESTful web APIs.
Experience building custom features, extensions, or applications, in addition to integration work, ideally including some exposure to delivering a standalone solution for a customer or internal team.
Good understanding of security concepts as they apply to applications, integrations and APIs, including secure handling of data in transit and at rest.
Practical experience with authentication and authorisation methods, such as OAuth 2.0, OpenID Connect, JWT, API keys, and mutual TLS, and an understanding of when each is appropriate.
Comfortable working with common data formats such as JSON and XML, and familiar with version control (Git) and CI/CD practices.
Strong problem-solving skills and the ability to take a solution from requirements through to production support, debugging across system boundaries where needed.

What Else Looks Good For This Role

Experience with message brokers or event-driven architectures (e.g. Azure Service Bus, RabbitMQ, Kafka).
Familiarity with cloud platforms, with Azure preferred.
Exposure to integration platforms or middleware (e.g. Azure Logic Apps, MuleSoft, BizTalk).
Understanding of API gateways and rate limiting.
Awareness of common security standards and threats, such as the OWASP API Security Top 10.
