Senior Platform Engineer - Observability

About RHAELM RHAELM is the sovereign AI cloud built to accelerate secure AI deployment at scale , combining power and infrastructure pipelines with global capability and local, in-country operations . Headquartered in London, with deployments across Europe and APAC , we deliver ring-fenced compute, networking, and storage infrastructure alongside a sovereign platform and flexible Bare Metal, Kubernetes, and AI-as-a-Service models . Focused on regulated and mission-critical sectors including Government, Defence, Healthcare, and Financial Services , we give organizations sovereign control over their AI infrastructure, platform, and data.

OUR TEAM We’re growing in Poland with a brand-new team hub in Wrocław . As we build our local community, we’re searching for top tech enthusiasts and industry experts to join the journey. If you want to build mission-critical solutions on an impressive scale - join us!

We’re looking for new team members to join our o bservability team . We build the telemetry platform that the rest of the company runs on. Every layer of our infrastructure reports into it - from facility and power, network fabrics, bare-metal hosts and their management controllers, to GPUs , the control plane, and the managed Kubernetes running above it.

About The Role

• Building and maintaining core platform infrastructure: Managing Kubernetes clusters, CI/CD pipelines, artifact registries, and identity & secrets management systems
• Driving automation and tooling: Implementing Infrastructure as Code (IaC), streamlining operational workflows, and developing tools for engineering and ops teams
• Ensuring reliability and security: Focusing on supply chain security, deployment repeatability, and production environment stability
• Coding for automation and integration: Writing code primarily for smart process automations, system integrations, and batch operations (e.g., data migrations, auto-synchronizations)

YOU ARE A PERFECT MATCH IF YOU HAVE

• A track record of designing, building and running production observability platforms at scale (LGTM stack or ELK): metrics with long retention and high cardinality, log aggregation and distributed tracing
• Deep experience with OpenTelemetry: instrumenting applications and infrastructure, and building telemetry pipelines (collection, processing, sampling, routing)
• Experience defining SLIs/SLOs and alerting strategies
• An observability-as-code mindset: dashboards, alerting rules and data sources versioned and validated in CI
• A solid DevOps foundation: hands-on Kubernetes operations, IaC in production (Terraform, Ansible), CI/CD and GitOps
• Linux knowledge at the level of diagnosing problems, plus professional Python experience (async programming, FastAPI) for building tooling, exporters and integrations
• Ownership of architectural decisions and the ability to set observability standards across teams
• English at B2+ level or higher

NICE TO HAVE

• Multi-tenant observability with real per-tenant isolation (queries, retention, encryption keys)
• Low-level telemetry: eBPF, hardware and network devices (SNMP, syslog, gNMI, BMC interfaces), GPU accelerators and RDMA networking
• Continuous profiling
• Golang, e.g. for extending OpenTelemetry Collector or writing exporters
• Advanced platform skills: self-managed Kubernetes, packaging and versioning manifests, software-defined storage
• Security fundamentals: secrets management, PKI, mTLS and automating the certificate lifecycle
• SIEM experience: normalization, event taxonomy, index design, capacity planning

What We Offer

• Work on every layer of an AI Factory - from the hardware and the newest GPU architectures up to the software that runs training and inference, on infrastructure measured in hundreds of megawatts
• Work alongside a team of highly experienced Cloud and Infrastructure experts in building mission-critical solutions
• Collaborate with international Client and internal teams across the UK, Japan and other top-tier tech hubs
• Real impact - directly shape and influence the final design of our infrastructure, applications, and processes
• Friendly start-up culture where everyone knows each other, help is always around the corner, and regular team integration events keep us connected
• We offer full-time employment based exclusively on an employment contract
• Comprehensive private healthcare (Medicover Premium) plus affordable family packages
• Hybrid model (3 days in-office) - work from our office located right at Nowy Targ in Wrocław
• MultiSport Plus card, with option to add family members and partners at preferential rates
