Platform Engineer GCP / AWS Docker & Kubernetes Terraform Linux Stockport - Hybrid working (2 days per week onsite) Up to 70,000 + 10,000 On-Call Allowance + Benefits A well-established tech company in Stockport is looking for an experienced Platform Engineer to join their team. They've recently completed a large-scale migration from their traditional data centre into Google Cloud Platform and are now looking for someone to help them improve, maintain and develop their cloud infrastructure. You'll be joining a small and experienced Platform team, working closely with their Software Engineers to make sure their systems are secure, reliable and performing well. This is a genuinely hands-on role, with a good mixture of modern cloud technologies alongside traditional infrastructure and troubleshooting. They're not looking for someone to come in and architect an entirely new cloud platform from scratch. The migration to GCP has already happened, so the focus now is on incremental improvements - improving automation, monitoring and reliability, refactoring where necessary and making the platform easier for their development teams to work with. They work with a modern infrastructure stack including GCP, Docker, Kubernetes, Terraform, FluxCD and GitHub, alongside a predominantly Linux-based environment. You'll ideally have experience with most of the following: Strong Linux infrastructure and troubleshooting skills Docker and containerised environments Kubernetes Terraform / Infrastructure as Code Monitoring, logging and troubleshooting production systems Cloud platforms - ideally GCP or AWS CI/CD and deployment tooling Previous GCP experience would obviously be useful, but it isn't essential. They're very open to someone coming from a strong AWS background who understands cloud infrastructure and has solid experience with Docker, Kubernetes and Terraform. More than anything, they're looking for someone who understands the technologies they work with rather than simply having exposure to them. You should enjoy troubleshooting problems, digging through logs and understanding why something isn't working. The company has a really good culture and people tend to stick around for a long time. They're independently owned, have a relatively small technology team and have created a collaborative environment where the Platform and Software teams work closely together. They've also recently purchased their own office in central Stockport, which is currently being renovated into a new purpose-built space for the team. They support hybrid working, with everyone getting together in the office on Wednesdays and Thursdays. There is also the opportunity to join their paid on-call rota once you're comfortable with the environment. This adds around 10,000 per year to the package, alongside additional days off. In return, they can offer: Salary up to 70,000 Circa 10,000 additional on-call allowance 35-hour working week Flexible working around core hours Hybrid working - 2 days per week in Stockport 25 days holiday + bank holidays Additional holiday for those participating in on-call Matched pension up to 5% Private healthcare / healthcare cash plan Regular team lunches, socials and company events This would be a great opportunity for an experienced Platform, DevOps, Cloud or Infrastructure Engineer who enjoys being hands-on and wants to work across modern cloud technologies without losing the troubleshooting and infrastructure side of the job. Interested? Apply now or get in touch for more information - even if you don't have a CV ready, we're happy to chat. Cathcart Technology is acting as an Employment Agency in relation to this vacancy.

Implement and maintain client quotas, broker quotas, throttling, and back pressure strategies. Plan and execute upgrades/patching with zero/minimal downtime; maintain version currency against EOL and security advisories. Own backup/restore workflows for metadata (eg, cluster configs), Schema Registry, and Connect configs Implement authentication (mTLS/SASL: SCRAM, OAUTHBEARER with IdP, or Kerberos if Legacy) and authorization (Kafka ACLs, Confluent RBAC).

Analyze broker hotspots, partition skew, large message handling, compaction and retention settings, and tune GC/JVM for sustained throughput. Implement consumer lag monitoring and alerting with actionable runbooks to prevent data loss or SLA breaches. Model workload growth, topic/partition scaling, storage/IOPS, network egress/ingress, and broker sizing. For Confluent Cloud, optimize environment - cluster - topic hierarchy, throughput tiers, retention costs, and data flow egress; right size Dedicated vs. Standard clusters. Design partitioning strategies to meet throughput targets while balancing consumer concurrency and avoiding small partitions anti patterns Automate cluster and topic life cycle using Terraform (providers for Kafka/Confluent), Helm, GitOps workflows. Operate and scale Kafka Connect with distributed workers; manage connectors (JDBC, Debezium CDC, S3/ADLS/GCS, Elasticsearch, etc.), transforms (SMTs), and converter settings. Administer Schema Registry (compatibility levels, subject naming strategies, serializers/deserializers, schema size & references). Operate ksqlDB and/or Flink for streaming SQL; enforce resource limits and multi tenant governance.
