Event Driven Software Engineer

Event Driven SME Software Engineer

Contract: Inside IR35
Location: Sheffield – 2–3 days per week

We’re looking for an experienced Event Driven SME Software Engineer to join a greenfield project building a large-scale, high-throughput platform processing billions of cloud telemetry and log events every day.

You’ll be hands-on with the design and engineering of event-driven data ingestion and streaming capabilities, helping shape the architecture, engineering standards and testing strategy across the platform.

Key Responsibilities

* Build high-volume, event-driven data ingestion pipelines across multiple Cloud Service Providers.

* Design and engineer streaming solutions using Kafka and Flink, with Java-based services and jobs.

* Deploy and operate cloud-based services with a focus on scalability, resilience, security and observability.

* Contribute to technical architecture covering event schemas, partitioning, ordering, state, replay, retention and failure handling.

* Optimise solutions for performance and cost at significant scale.

* Establish mature automated testing across unit, integration, contract, end-to-end and performance testing.

* Work with cloud-native data collection approaches across AWS, Azure and GCP.

* Contribute to CI/CD, infrastructure automation and operational best practices.

Essential Experience

* Proven experience delivering large-scale event-driven systems in production.

* Strong hands-on Kafka experience, including partitioning, consumer groups, ordering, schema evolution, retention and replay.

* Strong hands-on Flink or equivalent stream-processing experience, including stateful processing, checkpoints, back-pressure and delivery semantics.

* Excellent software engineering skills, with strong knowledge of clean code, design patterns, microservices, TDD/BDD and performance engineering.

* Strong cloud engineering experience, ideally AWS.

* Demonstrable experience building robust automated testing strategies and driving a quality-first engineering culture.

* Strong understanding of scalability, performance, bottlenecks and cost optimisation at high volumes.

Desirable

* Multi-cloud telemetry/log collection experience across AWS, Azure and GCP.

* Terraform and Infrastructure as Code.

* Strong CI/CD and automated deployment experience.

* Experience contributing to cloud/application architecture while remaining hands-on technically.

* Observability and SRE practices.

This is a genuinely hands-on SME role for someone who can make architectural decisions, write production-quality code and build platforms that are scalable, resilient, testable and cost-effective
