[Hiring] Senior Engineer - Platform @Buildkite

Role Description

We’re hiring a Senior Platform Engineer to join our Platform engineering organisation. The Platform team builds and operates the shared foundations that help Buildkite teams ship and scale products securely and reliably.

This is a hands-on role for a senior platform engineer with strong cloud and infrastructure foundations. You’ll design and operate reliable Kubernetes platforms across multiple clusters, solve distributed-systems challenges, automate infrastructure at scale, and take ownership of the systems you build.

We’re also hiring a Platform Engineer at intermediate level. If you’re earlier in your career than this role describes but the work below appeals, apply anyway and we’ll consider you.

Qualifications

• Clear communication and effective collaboration in a distributed team.
• Technical influence: navigating ambiguity, explaining trade-offs, building consensus, and driving cross-team work.
• Developer experience: Experience building CI/CD, internal-platform, or self-service capabilities that make the safe path easier for other engineers.
• Experience owning production systems through growth, failures, migrations, and incidents.
• Production AWS, Kubernetes, and infrastructure-as-code experience.
• Infrastructure as Code: Experience managing production infrastructure with Terraform or an equivalent tool, including DNS, IAM, monitoring, and secrets.
• Strong reliability practices, including observability, incident response, recovery testing, and operational improvement.
• Experience building platforms or self-service capabilities that make secure, reliable delivery easier for engineers.

Requirements

• Multi-region or multi-cluster systems, traffic routing, and disaster recovery.
• Progressive delivery, deployment guardrails, and rollback.
• Platform-level authentication, identity, or compliance controls implemented through engineering rather than paperwork.
• Datastores: Experience operating relational databases, caches, or queues, including migrations, replication, failover, and workload isolation.

Benefits

• Work from anywhere in the world for up to 6 weeks a year, on top of a fully remote setup.
• 20 days paid annual leave plus 10 days sick & carer's leave.
• 16 weeks paid parental leave for primary carers (6 for secondary).
• A remote-work allowance for home-office kit, co-working, or working elsewhere.
• Confidential EAP & mental health support.
• Support for learning and growth with time and budget for conferences, courses, and coaching.
• Retirement and health coverage (based on your region).
