Hackajob Ltd; Leeds; On-site; GBP 61,000 - 101,000; Full time

Job summary

Hackajob Ltd. is seeking a Site Reliability Engineer to enhance the reliability, observability, and operability of customer‑facing digital banking services. You will join a distributed, cross‑functional team to reduce toil and improve resilience across microservices.

The role requires hands-on experience with Kubernetes, AWS, and monitoring stacks (Grafana/Prometheus/Elasticsearch/Kibana). Strong scripting and AI-assisted tooling experience are also valued.

Qualifications

• Formal training or certification in software engineering concepts.
• Proven software engineering experience in at least one language (Python/Go/Java).
• Experience designing, coding, testing and delivering software in at least one tech stack.
• Strong debugging and troubleshooting across distributed systems.
• Experience as an SRE or supporting production services in an SRE capacity.
• Working knowledge of microservice infrastructure: service discovery, ingress, networking, load balancing.
• Experience with Kubernetes and cloud computing services.
• Familiarity with observability tools (Grafana, Prometheus, Elasticsearch, Kibana, Jaeger).
• Ability to use AI-assisted engineering tools responsibly, validate outputs, and handle sensitive information securely.
• Preferred: AWS experience.
• Preferred: building internal reliability tooling (CLI tools, automation pipelines, operators).
• Preferred: improving developer experience via golden paths, templates, or reusable patterns.
• Preferred: applying AI to operational workflows with approved tools and patterns.

Responsibilities

• Improve reliability, monitoring, and alerting of mission-critical microservices.
• Reduce operational toil by automating processes and building reliable infra and tooling.
• Develop service metrics, SLIs/SLOs, error budgets, dashboards, and alerts.
• Work with development teams to design services for reliability and scale.
• Design self-healing and resiliency patterns (graceful degradation, rate limiting, circuit breakers, failover).
• Partner with engineering, product, and platform teams to promote reliability standards.
• Conduct performance testing and capacity planning to address bottlenecks.
• Incorporate metrics, alerting, logging, automation, resiliency, capacity in feature planning.
• Use approved AI tools for root-cause analysis, log/traces, runbooks, post-incident reviews, test scaffolding, docs.
• Develop AI skills: prompting, output validation, automation workflows, safe usage practices.
