Job description

Job Description

Purpose of the role: To design, develop and improve software, utilising various engineering methodologies, that provides business, platform, and technology capabilities for our customers and colleagues.

Accountabilities

• Development and delivery of high‑quality software solutions by using industry‑aligned programming languages, frameworks, and tools.
• Ensuring that code is scalable, maintainable, and optimised for performance.
• Cross‑functional collaboration with product managers, designers, and other engineers to define software requirements, devise solution strategies, and ensure seamless integration and alignment with business objectives.
• Collaboration with peers, participation in code reviews, and promotion of a culture of code quality and knowledge sharing.
• Staying informed of industry technology trends and innovations and contributing to the organisation’s technology communities to foster a culture of technical excellence and growth.
• Adherence to secure coding practices to mitigate vulnerabilities, protect sensitive data, and ensure secure software solutions.
• Implementation of effective unit testing practices to ensure proper code design, readability, and reliability.

Expectations

• Perform prescribed activities in a timely manner and to a high standard consistently driving continuous improvement.
• Requires in‑depth technical knowledge and experience in their assigned area of expertise.
• Thorough understanding of the underlying principles and concepts within the area of expertise.
• Lead and supervise a team, guiding and supporting professional development, allocating work requirements and coordinating team resources.
• If the position has leadership responsibilities, demonstrate a clear set of leadership behaviours: L – Listen and be authentic, E – Energise and inspire, A – Align across the enterprise, D – Develop others.
• If an individual contributor, develop technical expertise in the work area, acting as an advisor where appropriate.
• Partner with other functions and business areas, take responsibility for end results of a team’s operational processing and activities, and advise and influence decision making within own area of expertise.
• Take ownership for managing risk and strengthening controls in relation to the work you own or contribute to, delivering work in line with relevant rules, regulation and codes of conduct.

Role Focus: Software Engineer – Observability

• Design, implement, and integrate end‑to‑end observability solutions by instrumenting applications and platforms with Metrics, Events, Logs, and Traces (MELTs), ensuring consistent visibility across distributed systems.
• Integrate application using OpenTelemetry (OTEL), with strong preference for the Grafana suite, enabling unified monitoring, visualisation, and operational insight.
• Develop and maintain high‑quality dashboards that provide actionable insights into system health, performance, capacity, and business‑critical metrics, tailored for engineering, operations, and senior stakeholders.
• Define and implement alerts, notifications, and escalation mechanisms using metrics and logs.
• Apply observability best practices to Kafka‑based event‑driven systems: integrate Kafka clients (producers and consumers), monitoring broker health, consumer lag, throughput, latency, error rates, and topic‑level behaviour.
• Implement observability for NoSQL data stores (MongoDB preferred), capturing performance metrics, query behaviour, resource utilisation, and failure patterns.
• Work within cloud‑native environments (AWS preferred) to implement observability across compute, storage, networking, and managed services, ensuring alignment with Barclays security and resilience standards.
• Contribute as an Individual Contributor (ICE), owning end‑to‑end technical delivery of observability capabilities from design and implementation through to production readiness and ongoing optimisation, with minimal supervision and strong engineering accountability.
• Operate effectively within Agile / Scrum delivery models, actively participating in sprint planning, refinement, reviews, and retrospectives, with practical experience using Jira for backlog management.
• Demonstrate excellent verbal and written communication skills, able to articulate technical concepts to both technical and non‑technical stakeholders.
• Collaborate with cross‑functional teams including application engineers, DevOps, SRE, security, platform, and architecture teams to deliver cohesive and well‑integrated solutions.
• Deploy and operate applications and monitoring components on Kubernetes, with hands‑on experience observing containerised workloads, pods, services, and cluster‑level behaviour.
• Integrate observability into CI/CD and DevOps pipelines using Git and DevOps toolchains, enabling early detection of issues through automated checks, deployment health validation, and post‑release monitoring.
• Apply strong understanding of microservices architecture, event‑driven design, and distributed systems principles to ensure observability is designed‑in rather than retrofitted.
• Hands‑on understanding of stream‑processing frameworks such as Apache Flink for stateful stream‑processing jobs.
• Implement and operate observability with Grafana LGTM stack: Loki, Tempo, Mimir; support production systems, contributing to incident response, root‑cause analysis, and continuous improvement.
• Hands‑on experience with Docker Desktop for local containerised development, IntelliJ IDEA or equivalent enterprise IDEs, secure source control, branching strategies, and automated quality gates.

Required Skills & Competencies

• Knowledge of cloud‑native technologies, distributed streaming platforms, Kubernetes orchestration, and multi‑region architecture patterns.
• Experience with OpenTelemetry (OTEL) and Grafana suite.
• Proficiency with Kafka, NoSQL (MongoDB preferred), AWS services.
• Experience deploying and monitoring microservices and containerised workloads.
• Strong communication and stakeholder engagement abilities.
• Self‑motivation, proactive risk identification, and continuous improvement.
