Sr. Platform Engineer

Job Description

- Design, build, and operate a secure and reliable internal platform for running business applications and machine learning workloads at scale.

- Develop and maintain self-service capabilities (golden paths) for provisioning infrastructure, deploying workloads, and managing the application lifecycle through standardized APIs, templates, and automation.

- Build and evolve reusable platform primitives such as K8s clusters, ingress, service networking, secrets management, policy controls, and identity integration.

- Maintain cloud and platform infrastructure using Infrastructure as Code (e.g., Terraform, Pulumi, Crossplane) in a secure, scalable, and reusable manner, including modular design, versioning, policy guardrails, automated validation, and safe rollout practices.

- Implement and maintain platform-level CI/CD patterns that support multiple teams while enforcing secure and compliant SDLC practices.

- Provide opinionated reference architectures and reusable building blocks (e.g., Helm charts, Argo CD apps, Terraform modules, scaffolding tools) that enable consistent delivery.

- Implement guardrails for security and compliance (policy-as-code, least privilege, workload identity, image provenance, runtime controls) while maintaining developer velocity.

- Own platform observability by establishing monitoring, logging, tracing, alerting, and SLO practices to keep the developer platform stable and measurable.

- Drive platform reliability and operational excellence through incident response, root cause analysis, postmortems, and continuous improvement to reduce toil.

- Support daily operations, monitoring, and security functions of the platform stack, including routine maintenance, access and identity workflows, vulnerability remediation, and operational support for internal platform services.

- Partner closely with application teams and stakeholders to understand friction points, prioritize the platform roadmap, and deliver measurable improvements in developer experience and time-to-production.

- Lead through influence and consensus, providing technical guidance, reviews, and mentorship to peers and junior engineers.

- Own your professional development, continuously learning new technologies and domain context to operate as a subject matter expert (SME).

- Bachelor's degree in Computer Science, Information Technology, Engineering, or a related field.

- Hands‑on experience designing and operating platform services using Infrastructure as Code (Terraform, Pulumi, Crossplane, or CSP-native tooling) with a modular, reusable approach.

- Strong experience with K8s or Open Shift and core platform components, including networking, ingress, service discovery, storage, RBAC, admission control, and multi‑tenancy.

- Experience implementing and standardizing CI/CD for multi‑team environments, ideally with Git Hub Actions and Argo CD, including release strategies and deployment automation.

- Experience with at least one major Cloud Service Provider such as Azure, GCP, or AWS.

- Strong networking fundamentals, including DNS, TLS, load balancing, routing, and private connectivity.

- Strong security foundations across identity, application, data, network, and supply‑chain security, including scanning, signing, SBOM, secrets handling, and policy enforcement.

- Strong software engineering fundamentals and experience building internal tooling and automation, ideally in Go, Python, or Type Script.

- Experience with containers and container tooling, including Docker, registries, and image build pipelines.

- Excellent knowledge of Linux operating systems and operational troubleshooting.

- Proven experience leading incident response, including triage, mitigation, coordination across teams, and driving post‑incident improvements.

- Deep knowledge of observability tooling and practices, such as Prometheus, Grafana, and Datadog.

- Strong problem‑solving and analytical abilities, with excellent communication and cross‑functional collaboration skills.
