Senior Platform Engineer

Senior Platform Engineer

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Senior Platform Engineer based in Ireland.

As a Senior Platform Engineer, you'll build the shared infrastructure and platform capabilities that enable engineering teams to deploy, operate, and scale services across a globally distributed environment. You'll work hands-on across bare-metal infrastructure, Linux, Kubernetes, and cloud technologies to solve complex platform challenges. Your focus will be on creating self-service tools, automating operational work, and making infrastructure simpler and more resilient.

You'll work closely with Infrastructure and Engineering teams to turn recurring problems into scalable, reusable solutions. The role combines deep technical ownership with a strong focus on observability, reliability, and developer experience. In a small, highly autonomous team, you'll have significant influence over platform decisions and the systems used by engineers around the world.

• Design and build self-service platform capabilities that enable engineering teams to deploy and operate workloads efficiently.
• Shape and improve workload deployment practices, including Git Ops and Kubernetes-based workflows.
• Develop and maintain global hybrid infrastructure spanning bare-metal servers, Linux systems, containers, and Kubernetes.
• Automate repetitive operational tasks and transform recurring infrastructure challenges into reusable tools and solutions.
• Design platform systems with scalability, resilience, reliability, and failure scenarios in mind.
• Improve system visibility through meaningful observability, including metrics, logs, alerts, and operational runbooks.
• Work closely with engineering teams to identify infrastructure friction and develop platform capabilities that address their needs.
• Own the systems and services you build through production, including participation in a follow-the-sun on-call rotation.
• Contribute to Infrastructure-as-Code, CI/CD pipelines, deployment automation, and platform engineering practices.
• Build practical internal tooling using technologies such as Go, Python, and Bash.
• Operate and support production databases and related infrastructure where required.
• Contribute to security, identity, and compliance initiatives and translate requirements into robust engineering solutions.
• Participate in technical decisions around when to use bare metal, Kubernetes, managed services, or other infrastructure approaches.
• Continuously improve platform architecture, developer experience, operational processes, and infrastructure reliability.

• Strong professional experience working with large-scale, multi-region Linux infrastructure.
• Hands-on experience operating Kubernetes in production environments.
• Proven experience building platforms, infrastructure tooling, automation, or workflows designed for other engineers.
• Strong understanding of distributed systems and core infrastructure concepts, including DNS, HTTP, TLS, networking, and containers.
• Practical experience with Infrastructure-as-Code and CI/CD practices.
• Proven experience owning production observability, including metrics, logging, alerting, monitoring, and runbooks.
• Ability to develop useful engineering tools and automation, particularly using Go, Python, and/or Bash.
• Experience operating production databases such as PostgreSQL, MariaDB, Redis, Click House, or Elasticsearch.
• Strong understanding of infrastructure reliability, scalability, failure modes, and operational resilience.
• Comfortable working across multiple engineering teams, time zones, and sometimes incomplete or ambiguous information.
• Strong ownership mindset, with the ability to take platform and infrastructure projects from concept through production.
• Experience with globally distributed infrastructure or internet-scale products is a strong advantage.
• Ability to make pragmatic infrastructure choices between bare metal, Kubernetes, and managed services based on actual requirements.
• Experience with Argo CD, Flux, or comparable Git Ops technologies is a plus.
• Familiarity with OIDC, SAML, and SSO is…
