Collaborate with the Head of DevOps on cross-domain architectural decisions that span telco and enterprise systems

Design and build integrations between BSS and OSS systems including billing (Sage), order management, and ServiceNow

Develop and maintain RESTful APIs for inter-system communication, ensuring resilience, idempotency, and fault tolerance

Build middleware and orchestration layers to support complex telco business processes (provisioning, service activation, order fulfilment)

Implement event-driven architectures using message queues (RabbitMQ, Kafka, or similar) for asynchronous system communication

Develop observability pipelines including logging, metrics, alerting, and dashboarding for telco platform health

Ensure data consistency and integrity across integrated systems through validation, error handling, and reconciliation logic

Lead and technically mentor a team of five engineers: Billing Systems Developer, OSS Systems Developer, UE Management Specialist, and API/Portal Backend Developer

Demonstrated experience as a tech lead, principal engineer, or technical design authority, with evidence of owning architectural decisions and being accountable for their outcomes

Strong proficiency in Python, with production experience building API-driven microservices using frameworks such as Django REST Framework, Fast API, or Flask

Hands-on experience with REST API design, development, and governance, including versioning, authentication (JWT/OAuth), documentation (Swagger/OpenAPI), and contract-first design

Experience with distributed systems patterns including message queues (RabbitMQ, Kafka, NATS), event-driven architectures, retry/fail-safe logic, circuit breakers, and graceful degradation

Solid experience with cloud platforms (AWS and/or Azure) including containerisation (Docker), CI/CD pipelines, and multi-environment deployment practices

Experience with relational databases (PostgreSQL, MySQL) including schema design, data modelling, query optimisation, and cross-system data reconciliation

Track record of mentoring and leading engineering teams of 3-6 people, including conducting code reviews, setting standards, and driving delivery

Strong documentation and communication skills, including the ability to produce ADRs, integration design documents, and API contracts

Ability to troubleshoot complex integration failures across multiple systems in production environments

Experience in telecommunications, ISP, or network service provider environments - this is strongly preferred given the telco-facing nature of the role

Direct experience with telecom provisioning systems, network management platforms, or BSS/OSS integration

Familiarity with TM Forum Open APIs and the Open Digital Architecture (ODA), particularly APIs related to service ordering (TMF641), product catalogue (TMF620), and resource management (TMF639)
