Software Engineering Professional

The Software Engineering Professional supports the execution of BTs software engineering strategy through cross-functional delivery, contributing to the development of technical solutions and platforms that enable innovation and engineering excellence.

Backend Development & Microservices
Design, develop, and maintain scalable microservices using Java (Spring Boot), with a focus on performance, modularity, and maintainability. Implement inter-service communication using REST and Kafka for event-driven architectures.

Frontend Engineering
Build interactive and intuitive web applications using React, ensuring responsive design, accessibility, and state management with Redux or similar libraries. Collaborate with UX/UI designers to bring user-centric designs to life.

Database Engineering
Work with relational databases like PostgreSQL/MySQL, crafting complex queries and optimizing data access patterns. Integrate and manage NoSQL databases like MongoDB, caching using Redis, and graph databases such as Neo4j as needed. Leverage object storage systems (e.g., S3-compatible storage, MinIO) for managing unstructured data like images, documents, and logs.

Cloud-Native Development
Develop and deploy cloud-native applications on AWS, leveraging services like EC2, Lambda, S3, RDS, DynamoDB, EKS, and CloudWatch. Implement CI/CD pipelines, infrastructure-as-code (IaC), and automated deployment strategies.

Event Streaming and Messaging
Integrate and manage Apache Kafka for high-throughput event processing and real-time data pipelines. Design robust Kafka consumers/producers with a focus on scalability and fault tolerance.

Testing & Quality Assurance
Write unit, integration, and end-to-end tests using JUnit, Mockito, Cypress, or equivalent tools to ensure code quality and system reliability. Participate in code reviews and enforce best practices across the full stack.

DevOps & Observability
Monitor application health using logging and APM tools (e.g., Dynatrace); implement alerts and dashboards for proactive issue resolution. Contribute to performance tuning, load testing, and system hardening.
    
Innovation & Continuous Learning
Stay current with evolving tech trends including AI/ML (e.g., NLP, Agentic AI, LangChain, n8n), container orchestration, and serverless architectures. Participate in architecture discussions and POCs to introduce new patterns and technologies.

About us

BT Group was the world's first telco and our heritage in the sector is unrivalled.  As home to several of the UK's most recognised and cherished brands – BT, EE, Openreach and Plusnet, we have always played a critical role in creating the future, and we have reached an inflection point in the transformation of our business. 

Over the next two years, we will complete the UK's largest and most successful digital infrastructure project – connecting more than 25 million premises to full fibre broadband.  Together with our heavy investment in 5G, we play a central role in revolutionising how people connect with each other. 

While we are through the most capital-intensive phase of our fibre investment, meaning we can reward our shareholders for their commitment and patience, we are absolutely focused on how we organise ourselves in the best way to serve our customers in the years to come.  This includes radical simplification of systems, structures, and processes on a huge scale. Together with our application of AI and technology, we are on a path to creating the UK's best telco, reimagining the customer experience and relationship with one of this country's biggest infrastructure companies.  

Change on the scale we will all experience in the coming years is unprecedented.  BT Group is committed to being the driving force behind improving connectivity for millions and there has never been a more exciting time to join a company and leadership team with the skills, experience, creativity, and passion to take this company into a new era.

A FEW POINTS TO NOTE:

Although these roles are listed as full-time, if you're a job share partnership, work reduced hours, or any other way of working flexibly, please still get in touch.

We will also offer reasonable adjustments for the selection process if required, so please do not hesitate to inform us.

DON'T MEET EVERY SINGLE REQUIREMENT?

Studies have shown that women and people who are disabled, LGBTQ+, neurodiverse or from ethnic minority backgrounds are less likely to apply for jobs unless they meet every single qualification and criteria. We're committed to building a diverse, inclusive, and authentic workplace where everyone can be their best, so if you're excited about this role but your past experience doesn't align perfectly with every requirement on the Job Description, please apply anyway - you may just be the right candidate for this or other roles in our wider team.
