We at Coforge are looking for Backend Engineer in Sheffield, UK.

This is a hands-on, high-impact role for someone who thrives at the intersection of platform engineering and developer experience. You will become the crucial link between infrastructure and development — understanding pain points, designing elegant solutions, and shipping tools that make other engineers faster and happier.

What You'll Do

• Partner with Product Owners to deeply understand requirements and break them down into focused, deliverable items.
• Design and build robust, scalable microservices with high observability and supportability, following DevOps and Agile principles.
• Own your deliverables end-to-end — from design through deployment — and hit agreed timelines.
• Provide rapid, effective production support; perform root cause analysis on incidents and drive long-term fixes that stick.
• Act as a trusted technical consultant for platform users, resolving queries and unblocking teams with speed and clarity.
• Collaborate closely with cross-functional IT teams and coordinate stakeholder activities to keep the platform evolving.
• Proactively manage technical debt and keep security and vulnerability posture sharp.
• Mentor junior developers, share knowledge generously, and champion a high-performing team culture.

What You'll Need to Succeed

• Bachelor's degree (or equivalent) in Computer Science or a related discipline.
• 8+ years of software engineering experience, with at least 3 years in a leadership or technical lead role focused on DevOps, Platform Engineering, or SRE.
• Solid understanding of how the internet and HTTP work under the hood — DNS, TLS, load balancing, reverse proxies, service meshes, and API gateways — and how these come together in modern microservice architectures.
• Strong programming ability (structured and OOP) in one or more of: Java, JavaScript, Python, or Clojure.
• Hands-on experience with monitoring and observability tools such as Grafana and InfluxDB; familiarity with time-series databases and data visualisation concepts.
• A proactive mindset — you spot problems, performance bottlenecks, and improvement opportunities before they become urgent.
• Proven experience managing critical production incidents under pressure.
• Excellent communication and collaboration skills; comfortable working with cross-functional and geographically distributed teams.
• Demonstrated ability to rapidly learn new technologies and drive self-development and knowledge sharing within the team.

Nice to Have

• Strong knowledge of Linux/Unix systems and networking fundamentals.
• Hands-on experience with KVM/VMware virtualisation.
• Familiarity with cloud platforms (AWS, GCP, or Azure) and containerisation (Docker, Kubernetes).

This role supports Hybrid working.
