Role Title: Splunk and Openshift Observability Engineer

Location: Sheffield/Birmingham/London/ Hybrid - 2/3 days per week onsite

Duration: 8 months

Rate: £494 per day inside ir35

We're looking for a Splunk & OpenShift Observability Engineer to design, deploy, and optimise enterprise-grade monitoring across hybrid Kubernetes and OpenShift environments.

This is a high-impact role where you'll shape observability strategy, enhance service intelligence, and ensure platform reliability at scale - balancing performance, cost efficiency, and security governance.

You'll work at the intersection of platform engineering, observability, and service intelligence, helping to transform raw telemetry into actionable insight. This is an opportunity to influence reliability strategy, improve operational maturity, and deliver measurable value across a modern cloud-native estate.

What You'll Be Doing

Design, deploy, and operate Splunk Enterprise and ITSI across hybrid Kubernetes/OpenShift platforms

Onboard and normalise data at scale (HEC, Universal Forwarder, Deployment Server), aligning to CIM standards

Build and optimise ITSI service models: service trees, KPIs, adaptive thresholds, NEAP policies, glass tables, deep dives, and health scoring

Deliver OpenShift-focused executive and operational dashboards, including:

Cluster/API/etcd health

Node readiness and resource pressure

Pod restart trends and noisy-neighbour detection

Network and storage error visibility

Capacity, quota, and burst analysis

Optimise search and platform performance (workload rules, DMA, summary indexing, scheduling hygiene, concurrency tuning)

Implement intelligent alerting and automated routing into ITSM and ChatOps platforms, including enrichment, suppression windows, and maintenance scheduling

Govern data ingestion and security controls (RBAC, retention, PII handling, TLS, token governance, index and role mapping)

Integrate telemetry pipelines including OpenTelemetry, Prometheus, Fluentd/Fluent Bit/Vector, Kafka, CMDB and AIOps/ML solutions

Drive SLO/KPI alignment, golden signal monitoring, rollout/rollback health validation, and executive reporting

What You'll Bring

Deep expertise in Splunk Enterprise (SPL mastery, CIM alignment, saved searches, macros, KV stores, index/retention/RBAC design, performance tuning)

Strong experience with Splunk ITSI (service trees, KPIs, adaptive/time-based thresholds, NEAP tuning, Service Analyzer configuration)

Proven OpenShift/Kubernetes observability experience across control-plane metrics, events, logs, workload correlation, and capacity management

Hands-on experience with telemetry pipelines (OpenTelemetry/OTLP, Prometheus exporters, Fluentd/Fluent Bit/Vector, Kafka with TLS, HEC/UF/DS onboarding)

Strong understanding of reliability engineering principles (golden signals, SLO design, namespace/application KPI mapping)

Experience optimising performance and licensing costs using workload rules, DMA, and summary indexing

Solid security and compliance knowledge (TLS/mTLS, certificate/token hygiene, PII controls, auditability, role/index mapping)

Automation and integration expertise across ITSM, ChatOps, webhooks, CMDB enrichment, and AIOps tooling

Where to Advertise Space Jobs in the UK (2026 Guide)

Advertising space jobs in the UK requires a different approach to most technical hiring. The candidate pool spans satellite engineers, propulsion specialists, mission analysts, ground segment software developers, space systems architects and commercial space professionals — a highly specific multidisciplinary community that general job boards are poorly equipped to reach. The strongest space candidates are often embedded in ESA programmes, academic research groups, UK Space Agency-funded projects or established primes, and move between roles through sector-specific networks, industry bodies and conference communities rather than mainstream platforms. This guide, published by UKSpaceJobs.co.uk, covers where to advertise space industry roles in the UK in 2026, how the main platforms compare, what employers should expect to pay, and what the data says about hiring across different role types.

How Many Space Industry Tools Do You Need to Know to Get a UK Space Job?

If you’re pursuing a career in the space industry — whether that’s spacecraft engineering, mission operations, space software, satellite systems, ground segment integration or space data analytics — it’s easy to feel overwhelmed by the sheer number of tools, platforms and technologies mentioned in job adverts. One role wants experience with CAD and FEA software. Another asks for experience with GNSS simulation. A third mentions mission scheduling tools, RF link analysis suites, Python, C++, continuous integration — and it seems there’s always another acronym to learn. With so much listed, many candidates fall into the trap of thinking they must master every tool under the sun before they’ll be taken seriously. Here’s the honest truth most UK space hiring managers won’t say out loud: 👉 They don’t hire you because you’ve heard of every tool — they hire you because you can apply the right tools to solve real space problems, explain your reasoning clearly, and deliver results. Tools matter, but they always serve a purpose: achieving mission goals, improving reliability, reducing risk, delivering data, or enabling collaboration. Tools are enablers — not trophies. So how many tools do you actually need to know to get a space job? The answer is much fewer and far more strategic than you might think. This article breaks down: what tools employers really expect which ones are core across most space roles which ones are role-specific how to present your tool proficiency on your CV and in interviews
