Senior Software Engineer

Role Description

As a Software Engineer in the Telco Experience Team, you’ll help build and integrate APIs that power stakeholder-facing telco journeys, working closely with product managers, frontend engineers, and business stakeholders to deliver customer-focused features.

• Collaborate with core platform teams responsible for supplier integrations and shared infrastructure.
• Contribute to projects that shape how our telco products are experienced end-to-end.
• Work primarily with Go, Kafka, Kubernetes, Postgres, and MongoDB.
• Gain hands-on experience with event-driven systems and modern observability practices.

We’re looking for a backend-focused engineer who enjoys learning, collaboration, and contributing to frontend-heavy initiatives while building reliable services.

• Thrive if you’re curious, proactive, and comfortable working in a fast-moving, evolving team.
• Experience in regulated consumer services or consultancy is a plus.
• Value a growth mindset and a desire to build great customer experiences together.

Qualifications

• Experience with Go is preferred but not essential.
• Proven fluency with Postgres, Kafka, and Kubernetes.
• Solid experience building distributed systems, including concurrency and event-driven architectures.
• A strong understanding of system resilience, observability, uptime, SLAs, and progressive degradation.
• The ability to deliver end-to-end solutions, from design through build, deployment, and ongoing support.
• Experience working with CI/CD tooling, Terraform, and modern cloud workflows.
• Familiarity with Kafka and database migrations (e.g. CockroachDB to RDS) as a plus.
• Strong communication, collaboration, and problem-solving skills.
• The ability to thrive in an agile, iterative environment while delivering continuous feature improvements.
• Experience mentoring mid-level engineers and modelling engineering best practices.
• Comfort working in autonomous, product-focused teams.

Requirements

• Contribute to team goals by delivering well-scoped work that aligns with agreed objectives.
• Participate in prioritisation discussions and raise risks or opportunities as they arise.
• Design and implement reliable technical solutions within existing architectures and standards.
• Make sound technical decisions for your work, drawing on experience across relevant technologies and seeking guidance when needed.
• Deliver features and improvements from design through to completion with support from senior engineers.
• Balance quality and progress, address technical debt as part of regular work, and help keep services and processes maintainable.
• Build a solid understanding of the product and services your team supports.
• Understand how your work contributes to user and business outcomes, and factor this into day-to-day technical decisions.
• Work collaboratively through pairing, code reviews, and team discussions.
• Be open to feedback, support teammates when possible, and actively develop your technical and professional skills.
